Install OpenGL driver on CLE266
« on: July 23, 2020, 03:02:58 AM »
Hello. I have been trying one day to make OpenGL work on my PC (I know it is very old). Hardware: CLE266 chipset with VT8623 intergarted graphics, VIA C3 processor (Samuel 2, with 3DNow!, without SSE). ( newbielink:https://www.viatech.com/en/silicon/legacy/chipsets/cle266/ [nonactive]). Manuals said it has DirectX 7.0 and OpenGL support (but not specify which one).

What I need is any OpenGL context with possibility to compile shaders (OpenGL > 3.0, not sure about ES).

What I tried:
1) Written my app with EGL (newer verison fails with Illegal instruction, older - with "no protocol specified"), Freeglut ("GLX extension not supported on display ":0.0"") and SDL2 (Illegal instruction).
2) Launched apps with sudo
3) Builded my own SDL2, because thay said they have builtin KMS drivers. Result: KSM drivers not included.
4) Installed xf86-video-openchrome - no effect
5) Found VIA drivers (Debian, Suse, Ubuntu and others), tried to insmod - invalid module format.
6) Tried to compile from here ( newbielink:http://xorg.freedesktop.org/archive/individual/driver/xf86-video-openchrome-0.6.0.tar.bz2 [nonactive]) - package "dri" required by "xorg-server" not found

Please help. I will provide all configuration files/outputs needed. Thanks.

The minimum cpu for Xorg-7.7-3d (and thus libEGL, libGL) is pentium-m, you would have to go back to mesa-10.x/core-6.x to get away from this limitation.

What does this show:
Code: [Select]
$ cat /proc/cpuinfo | grep 'model name'
The xf86-video-openchrome extension should work for your hardware - you will be able to see if it is being used from /var/log/Xorg-0.log.

After you answered I tried to replace Xorg-7.7-3d with the version from 6.x, which resulted in BSOD (surely I don't it right)
Oh, and there is no /var/log/Xorg.log

If you want to use Xorg-7.7-3d from Core-6.x then you need to install Core-6.x.

Your GPU supports OpenGL 1.3, which is from ~2000 like DirectX 7. It doesn't support any kind of shaders at all.
The only barriers that can stop you are the ones you create yourself.

Oh, only 1.3... Well, now I can sleep soundly. Thank you.
