<buZz>
there are two connectors on that side of the board
<buZz>
one has a slightly higher connector
<buZz>
the shallow hole allows space for the higher connector
<lawrence>
also buzz - the ethernet is a bit of a female dog to fit
<buZz>
lawrence: yep, its ment that way
<lawrence>
as the metal spacer bits stick out
<buZz>
thats why its a Frictionfit case
<buZz>
USB, Ethernet and SATA are what the top holds on to
<lawrence>
so its angle in, but then its tight on the sata, so its a bit arggh fit dammit
<lawrence>
and the tolerance for the sata is too tight imho (as noted)
<buZz>
hehe yeah, push in the board when the printer only JUST finished, so the plastic is still a bit soft
<lawrence>
mine isn't soft that long, only soft as coming out
<lawrence>
even with preheated base
<buZz>
it should be, PLA over 60 celcius is still moldable
<lawrence>
ABS...
<buZz>
i never use ABS as it gives me terrible headaches
<lawrence>
there you go, thats the diff :)
<buZz>
;)
<buZz>
ABS should be softer than PLA though
<lawrence>
not when its about 0.8cm up already
<lawrence>
its pretty solid by that stage
<buZz>
no its softer
<lawrence>
as thats like 20 min into printing +-
<buZz>
you can always bend ABS
<buZz>
PLA just breaks
<lawrence>
i didn't time it
cheng has quit [Quit: Leaving]
<lawrence>
anyway, i did say thx for saving me doing it :)
<lawrence>
so i really can't complain at ALL
<lawrence>
thank you thank you thank you :)
<buZz>
;)
<hramrach>
lawrence: would be interested in some price and weight estimation of a thinkpad case adapted to accept a cubieboard or odroid or olinuxino or whatever
* lawrence
bows graciously
<buZz>
its fine, complain all you want :D
<buZz>
i dont feel offended ;)
<lawrence>
i'm always constructive criticism
<lawrence>
never otherwise
<buZz>
i think someday in the future i will design a new case
<lawrence>
eg its kak because 1,2,3,… not its kak
<buZz>
but for now this one fits my purpose
<hramrach>
if it can be done with off-the-shelf electronic adaptors that would be really cool
<lawrence>
can't do that in china though, you have to go softly softly
<buZz>
hramrach: motorola lapdock is nice ;)
<lawrence>
as telling people here like that, is going to get them all pissed and miffy
<hramrach>
buZz: no, it is not
<buZz>
lawrence: yeah i am not chinese :D
<lawrence>
so its always, hey great design, but if we try this next time...
<buZz>
hramrach: ok ;)
<lawrence>
dutch is easier
<lawrence>
straight to point, no hassle
<buZz>
we are mellow
<hramrach>
lame keyboard, lame screen, lame mechanics, the board does not fit inside
<buZz>
hramrach: i like the screen, 11" 1366x768 and nice brightness
<buZz>
the keyboard is a bit meh, i agree
<hramrach>
you can get full hd screen in a thinkpad
<lawrence>
i'm going for 1920x1080 for 11"
<buZz>
but all the apple fanboys think the keyboard looks great :D
<buZz>
lawrence: sweet
<lawrence>
just the eDP bit that worries slightly
<lawrence>
but eDP is DP in a diff format + power so not too hassleish
<lawrence>
and i found DP connectors already
<hramrach>
the problem is that with the board supporting only two display outputs one has to be connected to the internal panel
<buZz>
two display outputs?
<buZz>
simultanious?
<hramrach>
and if that's hdmi the one left is VGA/CVBS
<hramrach>
yes, some people use it reportedly
<lawrence>
i think for a mockup i would do DP + eDP display in 11 + thinkpad 12" case A/B + CD + hinge
<buZz>
why not connect internal panel with LVDS?
<lawrence>
LVDS panels > $
<lawrence>
for smaller sizes
<lawrence>
and everyone moving to ePD
<lawrence>
eDP
<lawrence>
eDP means no driver board needed too
<lawrence>
but if we need to support hdmi, need to have one
<hramrach>
if there was LVDS -> DP adaptor then maybe
<hramrach>
but yuo lose VGA
<lawrence>
there are
<hramrach>
so not that good tradeoff
<hramrach>
and extra $$ most likely
<lawrence>
there are multi use lcd driver i/c do vga, hdmi, dp … for cheap
<lawrence>
so not that bad
<buZz>
but there is a LVDS driverboard internal to A10
<lawrence>
yeah, but we're trying to not make a laptop
<lawrence>
and make a display
<lawrence>
well, thats initial idea
<hramrach>
yes, the adaptors I have seen are wrong way
<lawrence>
making a laptop would be cheaper
<lawrence>
as the a10 is dirt cheap
<buZz>
ah ok
<hramrach>
DP to anything
<hramrach>
or anything to LVDS
<buZz>
i would think a thinkpad still is a laptop ;)
<hramrach>
not LVDS to DP
<lawrence>
dp -> lvds
<lawrence>
has
<lawrence>
if people need it, there is a chipset that does it generally
Ershov has joined #arm-netbook
Ershov has left #arm-netbook [#arm-netbook]
<lawrence>
its not a wierd need, so they're out there
<hramrach>
yes but (board) LVDS -> DP (screen)
<lawrence>
honestly, worse case we stick an a10 or similar and screen grab the input, and stick output to lcd
<lawrence>
retarded, but i have seen solutions done like that
<hramrach>
and LVDS shares pins with VGA on A10 so no VGA then
<lawrence>
i priced out ethernet today
<lawrence>
ethernet costs < 5rmb here
<lawrence>
crazy
<hramrach>
or maybe cloned with some weird hack
<lawrence>
.9 for rj45 header, 3.5 rmb for realtek 100MB ethernet i/c and some misc resistors
<lawrence>
< 5rmb...
<lawrence>
(assuming on a larger pcb of course)
Gujs has quit [Read error: Operation timed out]
<hramrach>
ethernet is cheap
<lawrence>
yeah
<lawrence>
i didn't realise just HOW cheap
<lawrence>
and the power draw is quite minot
<hramrach>
but with cubieboard or other board with ethernet all you need is patch cable
<hramrach>
or mounting that edge at case edge but that would be rather difficult to pull off for multiple different boards
<hramrach>
if you stick the board someplace in the middle and mount it on piece of 3d printed plastic you can have compatibility with multiple boards
<lawrence>
for now not thinking at ethernet
<buZz>
sad thing that you machine will be superthick
<buZz>
or you can not use SATA
<lawrence>
as then need something to talk usb -> i2c -> ethernet
<buZz>
arduino? :P
<lawrence>
1-2rmb usb chip really, but complexity = cost
<Turl>
a keyboard with variants available (ñ :P) would be great
<lawrence>
sl300 casing
<lawrence>

<buZz>

<buZz>
pffff
<buZz>
taobao is a mess
<lawrence>
its not for you
<lawrence>
its for me
<lawrence>
:)
<buZz>
they use 3 different hosts for their javascript!
<lawrence>
anyway thats retail
<buZz>
come on man
<lawrence>
we would talk to factory direct
<lawrence>
but 35rmb for a chassis like that with mounting premade would be interesting i think
<lawrence>
if we did go 13.3"
* lawrence
needs to look for who makes 11" lappers and find casings..
<lawrence>
if we reused that case, stuck a screen in, used ibm keyboard, make a pcb to do screen + usb + keyboard would still have a build price < $100
<lawrence>
probably in the $70 odd range even
<lawrence>
which is interesting
<lawrence>
and thats in low volume
<lawrence>
thinkpad a10 :)
<buZz>
maybe one of those ancient Luggable computers would be a fun cubieboard case

because they're 3rd tier, and need to be friendly

which chip is it?
<jinzo>
exynos something something
<w00tc0d3>
jinzo: Exynos 5250?
<Jef91>
buZz: its a ARM Mali-T604 (Quad-core) @ 533 - 566MHz
<Jef91>
(68 - 72 GFLOPS)
<Jef91>
for the GPU
<Jef91>
Exynos 5 Dual (or 5250)
<buZz>
no, the video decoder
<jinzo>
and the prize goes to w00tc0d3 for being soo close.
<buZz>
thats not mali

yes, usually video decoder is separate
<w00tc0d3>
buZz: it is

ah

he is asking about accelerated video

GeorgeIoak, regarding the serious stuff (GPU/VPU) - doesen't look open on i.MX6
<jinzo>
but we'll see
<w00tc0d3>
buZz: ? Android needs certain interfaces/hals, and Samsung differs a lot of the standards. This developer is one with the biggest knowledge of CM. He's a legend lol
<GeorgeIoak>
i think there's a better chance i.MX6 opens up that any other part out now

w00tc0d3 - i agree, and given the stuff coming out of uh. china ;) no need really
<manoj_g>
@lawrence I did that, and its somewhat vast; anyway, I was hoping someone has same error for backlight
<buZz>
lets see what antutu gives on my tablet
<lawrence>
manoj_g i'd also check to see that your gpio's are what the driver expects.
<lawrence>
not uncommon for boards not to do things the right way
<lawrence>
i can look at that, and immediately go oh $$$$
<w00tc0d3>
buZz: why not? he clearly says he's making one for himself :)
<buZz>
exactly
<buZz>
w00tc0d3: yes, ONE
<buZz>
that board would cost >800 usd alone
<lawrence>
yup
<lawrence>
FPGA's gal(ore)
<lawrence>
:)
<lawrence>
slight joke there
<w00tc0d3>
buZz: it's possible to make 'friends' in the mobile industry ;)
<buZz>
i've met bunnie
<buZz>
he's nice
<buZz>
tablet scores 7629 on antutu
<w00tc0d3>
and with the right 'friends' you can do it in production
<w00tc0d3>
buZz: which tablet? :)

yeah fancy dreams

but it does show how easy it can be to make your own device
<buZz>
provided you study at MIT for a couple of years and have intimate connections with chinese factories :P
<lawrence>
not necessarily
<lawrence>
i can do it
<buZz>
;)
<lawrence>
and i don't MIT
<lawrence>
chinese is pretty useful
<lawrence>
and some sense
<buZz>
well, i mean, knowledge + connections

should land a job with some R&D firm with infinite budget
<lawrence>
so thats not as urgent
<lawrence>
and the crowdsourcing stuff works nicely
<lawrence>
for once
<buZz>
lawrence: hehe yeah, go make a chumby!
<buZz>
:P
* buZz
has a chumby
<lawrence>
the sony ones are so cheap here
<lawrence>
i can get for 100rmb
<lawrence>
but no source, no nothing
<buZz>
nice
<lawrence>
although for parts, its a temptation
<buZz>
isnt the source just chumby's source refactored?
<lawrence>
diff cpu
<buZz>
ah ok
<lawrence>
and its sonyt
<buZz>
i was thinking
<lawrence>
who are very nice about sharing and caring
<buZz>
maybe i should dump the NAND from cubieboard
<buZz>
and put it online
<buZz>
just for public backup
<lawrence>
can stick it on dl.cubieforums.com
<lawrence>
you want ftp?
<buZz>
you sure about that? ppl might be worried about binary blobs that are included
<lawrence>
its android
<GeorgeIoak>
buzz: what's in your nand
<buZz>
stock
<buZz>
just android + uboot, stuff like that
<buZz>
on cubieboard ML there are sometimes ppl complaining that they didnt back it up
ln2 has joined #arm-netbook
<lawrence>
thats all open, so i don't see issue
<GeorgeIoak>
just wondering cause why have it if the stock is already posted?
<buZz>
but what would be wise, just dd if=/dev/nand of=bla?
<buZz>
GeorgeIoak: nand is not posted
<buZz>
there are images posted which are not on the nand

'improvements'
<GeorgeIoak>
you mean different than livesuit img then?

what format is MTD using for nand

i will check it out shortly

lawrence: ran into my next hurdle. video playing sucks. mplayer uses 60-70% CPU with 720P and it won't even play smoothly. looks like vlc hasn't been touched since november. what's my options?
<lawrence>
better off hassling rz2k i think for video bits
<ln2>
The user ikcl is RT?
eFfeM has joined #arm-netbook
<lawrence>
or ask mnemoc if he has the vlc compile i saw recently on the mail list
<mnemoc>
me?
<lawrence>
you know more than me for stuff
<lawrence>
i'm a newbie
<GeorgeIoak>
mnemoc: have you compiled vlc?
<mnemoc>
never :)
<ln2>
What device are you using George?
<GeorgeIoak>
any work on video playback?
<lawrence>
a10 cubie
<GeorgeIoak>
cubieboard
<ln2>
Arch Linux?
<GeorgeIoak>
linao desktop
<ln2>
If you have a spare SD and time to kill. Try an Arch install and use the Arch ARM repository to install VLC.
<GeorgeIoak>
would it be quicker to just compile vlc?
<GeorgeIoak>
i'm nervous cause i just got lvds and touch screen working on the desktop
<GeorgeIoak>
don't want to have to reinvent the wheel again
<ln2>
That depends on a lot of factors. Arch will be generally faster to begin with. And the Arch ARM repository packages are optimized for your platform.
<lawrence>
should work for you, as does the cedarx bits
<lawrence>
can you paste your Xorg.0.log somewhere?
<GeorgeIoak>
was looking at that last night but seemed odd that nothing has happened since november
<lawrence>
lets check you have mali and cedar in your X
<ssvb>
GeorgeIoak: the problem is related to the missing scaling and colorspace conversion acceleration for mplayer, you may try to use Opengl ES or wait for XV extension
<GeorgeIoak>
yes i can, let me see if i can still ssh into my board from here
<GeorgeIoak>
ssvb: i've got a project that needs to ship this week so i'm out of time and sweating like crazy here
<ln2>
Doesn't XBMC work perfectly on the Cubie/A10?
<ln2>
Do you need to use VLC?
<lawrence>
he needs video that uses cedarx
<lawrence>
that was my initial easiest option thought
<GeorgeIoak>
can't really use xbmc, my project is more like a kiosk so i was thinking chromium browser in --kiosk mode
<lawrence>
suggest something better
<mnemoc>
he wants his *browser* to play cedarx accelerated videos
<ln2>
Ahh theres the trick. You might be out of luck with the browser idea.
<GeorgeIoak>
was going to develop a Qt app but even less time to do that
<GeorgeIoak>
going to paste my log in a second
<ssvb>
GeorgeIoak: adding "-vf format=rgb32 -vo gl:backend=3" options to mplayer should work to some extent, if you have working gles acceleration in your system
<lawrence>
ssvb is a good person to ask actually for you george
<lawrence>
i can't do pastebin, maybe someone else can check his mali etc drivers are in there and working
<ln2>
I hope you are right. All this competition is making for some really cool devices. =)

where else to paste lawrence
<ln2>
The one thing that has me is that the G-T16R is going to have full 3d acceleration in any OS. Yes from a binary blob. But actually working. Will we get that from an ARM soc in the next year? Two?
<lawrence>
binary blob, oh whoopee
<lawrence>
pas
<lawrence>
pass
<ln2>
GeorgeIoak: Try tny.cz =)
<lawrence>
that isn't blocked, so yeah
<ln2>
So you would rather have no 3D at all and flaky video codecs!
<w00tc0d3>
but me haz no adress to where me can ship it (in Germany)
<lawrence>
and get going
<lawrence>
should be slightly faster at least for stuff where it matters
<GeorgeIoak>
k thanks, will do
<ln2>
w00tc0d3: You should wait for a longer list of compatible Ubuntu Phones. =)
<w00tc0d3>
ln2: nexus is imho good enough =)
<ln2>
They have strict compatibility requirements for the kernel to run. Mostly the bootloader and chipset.
<ln2>
Only the Galaxy Nexus is listed as compatible right now.
<ln2>
Once they release it next month there will probably be a massive list of working phones within a few hours. =)
<lawrence>
is ubuntu going to be html5ish style or more andriody
<lawrence>
as i haven't looked at all
<w00tc0d3>
dunno
<GeorgeIoak>
ssvb: ran autogen.sh says i need xorg-macros but not found in apt-get
<w00tc0d3>
but Canonical has to get balls. Just design a new HAL system. Base it on GNU/Linux. Use Debian/Arch Linux as examples.
w00tc0d3 is now known as w00tc0d3__

<mnemoc>
good night lawrence
<ln2>
Lawrence you are still here! Haha
<ln2>
No its full Ubuntu. =)
<ln2>
No wrapper nonsense.
<GeorgeIoak>
is xorg-macros in xutils-dev
<lawrence>
gnome?
<ssvb>
GeorgeIoak: check http://linux-sunxi.org/Mali400 for the build instructions and the information about installing dependencies
<ln2>
I agree w00t but the phones that UP will run on are more than fast enough to run the full Ubuntu. It might sound like a waste but at least it works.
<lawrence>
you only need 16G flash to run etc ? snickers
<ln2>
Its a "Tiny Unity".
<lawrence>
tiny = 16g?
<lawrence>
one wonders...
<ssvb>
GeorgeIoak: it says "apt-get install build-essential autoconf automake make libtool xorg-dev xutils-dev libdrm-dev libdri2-1 libdri2-dev git"
<lawrence>
:)
<ln2>
No. The disk space is massive.
<ln2>
The interface is a "tinyfied" Unity
<ln2>
But you are infact running the full desktop OS.
<lawrence>
i just imagine the nand flash use being a tad high
<ln2>
It will be high. But its better than Android.
<lawrence>
unfinished, but possibly a little clearer
<ln2>
And better than Tizen. So its all we have. Haha
<ln2>
By "all we have" I mean actually based "mostly" on free software and actually runs native applications. Not Java / HTML5 crap.
<lawrence>
html5 stuff isn't bad
<lawrence>
i've done neat stuff in sencha

HTML5 can be a beast. But does anyone really want to port Audacity, KiCAD, GIMP to HTML 5 ect.?
<lawrence>
its not for that
<lawrence>
right tool, right job etc
<jinzo>
ln2, you could look up the GTK backend (broadway? named, or something like that) that allows rendering in a canvas
<jinzo>
so you can run your regular GTK programs in canvas on the web
<jinzo>
quite interesting project, don't have time to look it up for you tho.
<ln2>
Interesting. I will look into that.
<ln2>
If its as fast as native applications and actually works, that would make Tizen quite competitive with Ubuntu Phone.
<jinzo>
I was suprised by the demo.
<jinzo>
he opened gimp, and even the gnome browser inside the canvas
<ln2>
Maybe it comes down to a question I dont think any of us have the answer for. Which is. Does it make sense for all applications to eventually be HTML 5 or its equal? Does it make sense to do so when mobile CPU's can execute native applications with ease now?
<GeorgeIoak>
ssvb: do i follow everything on http://linux-sunxi.org/Mali400 or sub git clone git://github.com/linux-sunxi/xf86-video-mali.git with yours?
<ln2>
If the answer is No then I think we should stop wasting developers time re-writing software for HTML 5 / Java ect. ect. And now we can run the same software on servers, desktop, laptop, tablet, phones, embedded ect.
<techn_>
GeorgeIoak: that is arm's.. ssvb's stuff is ssvb's repo
<techn_>
GeorgeIoak: arm implementation has less bugs but poorer performance
<GeorgeIoak>
need performance to run 720P
<ssvb>
GeorgeIoak: yes, you are supposed to be able to replace one with another easily
<techn_>
ssvb: I'm still trying to find out where is the problem.. It has something to do with page flipping
<ssvb>
techn_: that's not a bug in X11 DDX, and it also affects xf86-video-mali
<techn_>
I havent seen it with xf86-video-mali
<lawrence>
my notes are incomplete, but a decent enough start to get 90% there
<ln2>
lawrence: Are you sure that you are going to sleep? Haha
<lawrence>
2:40am
<ln2>
=(
<lawrence>
but my compile just finished, and i need to test something quick quick
<ssvb>
techn_: I have seen it with glmark2-es2 and xf86-video-mali, the screen starts jumping on certain tests
<techn_>
ssvb: I can reproduce rendering problems in only 2d rendering (if page flipping is used) when scaling is disabled
mashku has joined #arm-netbook
<mashku>
Hi
<ln2>
mashku: Hello. =)
<mashku>
I am trying to make a Debian build for cubieboard
<ssvb>
techn_: it is easier to reproduce without scaler_mode set (I suspect that the display controller is buffering more pixels for scanout to hdmi in this case and it becomes harder to trigger buffer underrun)
<techn_>
but with scaling layer enabled page flipping works.. thats why xbmc propably forces scaling layer on
<mashku>
does it mean I need special bootloader ?/
<ln2>
jinzo: I'm really impressed with Broadway. Thanks for the info!
<ssvb>
techn_: does xbmc use gles?
<techn_>
ssvb: yes.. its flicker free on 1080p
merbzt has joined #arm-netbook
<ssvb>
techn_: does it really have no tearing? can you try it with people.freedesktop.org/~siamashka/files/20130130-tearingtest/tearingtest_480x480.webm ?
<ssvb>
techn_: "yes == uses gles" or "yes == is flicker free"?
<mashku>
I want to install debian on cubieboard, but I have couple of problems, standard debian installer net-inst wont work right ? do I need special bootloader? do I need special kernel? if I prepared rootfs.img with with ext4 on it.. how do I make a bootable sdcard ?
<ssvb>
techn_: in fact, seems like vsync works both with and without scaler_mode
<techn_>
ssvb: yes.. I noticed that.. vsync has following sequence: blanking interrupt -> write registers ok register -> registers ok interrupt -> trigger vsync
sky770 has joined #arm-netbook

any help?

install the toolchain?
<mashku>
I have crosscompiler in the path but it is called arm-linux-gnueabihf-gcc-4.7
<mashku>
Turl, yes from embed debian
<lawrence>
mashku -better to post to 1 place, not duplicate in both
<Turl>
why that weird name
<Turl>
?
<mashku>
Turl, it's gcc-4.7 in debian I dont know why that name
<lawrence>
i had to do
<lawrence>
for i in arm-linux-gnueabi*-4.7 ; do ln -s $i ${i%%-4.7} ; done
<mashku>
thx
<lawrence>
for aliases on deb
<GeorgeIoak>
well unfortunately there isn't any improvement, mplayer takes 60-70% and x takes the rest.
<Turl>
there probably is some update-alternatives to choose default -gcc version
<mashku>
Turl, I checked alternatives
<mashku>
no file for it
<lawrence>
georgeloak - make sure X shows you're using the mali + sunfb drivers now
<lawrence>
i honestly am going to bed now though. as my stuff i wanted to get done is done now.
<ssvb>
GeorgeIoak: which command line options do you use for mplayer? and what does it write to console? (you can make it more verbose by adding one or more "-v" options)
<mashku>
lawrence, isnt the hf newest arm ?
<lawrence>
hf = hard float
<mashku>
lawrence, so which is better ?
<lawrence>
the cubie has neon
<GeorgeIoak>
for now i just used gnome mplayer as the front end and opened the file, what should i try on the command line?
<ssvb>
GeorgeIoak: like I said before, something like "mplayer -vf format=rgb32 -vo gl:backend=3 yourvideofile.avi"
<ssvb>
GeorgeIoak: assuming that mplayer is compiled with GLES support enabled, otherwise you may need to recompile it
<ssvb>
GeorgeIoak: but first it makes sense to check whether the GLES acceleration works, can you try running glmark2-es2?
<GeorgeIoak>
error opening -vo device
<techn_>
ssvb: btw. thanks for that mplayer gles info :)
<GeorgeIoak>
glmark2-es2 isn't found
<techn_>
I thought that it only supports gl
<ssvb>
GeorgeIoak: try to apt-get install it
<ssvb>
techn_: the gles support is experimental in mplayer, and it does not really provide particularly impressive results
<GeorgeIoak>
ssvb:installing now
<GeorgeIoak>
OK, I see the spinning horse
<ssvb>
techn_: I just used it a bit for testing, there seem to be very few real OpenGL ES compatible applications available :-)
<ssvb>
GeorgeIoak: great, how much FPS does it show?
<ssvb>
GeorgeIoak: and does it report that it is using Mali-400 MP as a renderer?
<GeorgeIoak>
a whopping 0..1..2
<techn_>
ssvb: I have found and tested only es2_gears, glmark, glcomp, xbmc :(
<GeorgeIoak>
Software Rasterizer
<GeorgeIoak>
is the GL_Renderer
<techn_>
ssvb: with your driver it could be nice to test plasma :)
<ssvb>
techn_, libv: but I must say I'm really disappointed. Having projects like http://en.wikipedia.org/wiki/Pandora_%28console%29 around for years, I expected a lot of properly working problem-free open source GLES games :-/
<techn_>
ssvb: I thought that someone has made some 3d games for n900 and n9
<ssvb>
techn_: yes, there should be at least tuxracer available, but it needs maemo-specific bits ripped out
<ssvb>
GeorgeIoak: you need to install libMali.so
<libv>
ssvb: yes, it is quite terrible indeed
<libv>
ssvb: i would actually welcome a working gles2 game on top of the idtech4 (doom3) engine
<GeorgeIoak>
ssvb: ok, sory install libMali.so from where?
<libv>
sadly no-one has done a decent port of idtech4 yet
<w00tc0d3>
hum buZz, ping
<libv>
idtech3 was ported for n900
<techn_>
libv: I played quake2 on my n95 or was it n82 5 years ago :p

it was pretty cool that someone ported that for gles.. and symbian :)
