Hi, I refreshed my installation as You suggested and you were right some old files in /usr/local were interfering with new one from git. But now I still see some old problems which were reported not only by me. The problems are <ol><li>Random freezes when "faling back to classic mode", EXA with non GEM enabled kernels</li> <li>Not working GLSL in any case</li><ul><li>When I run Ethernal Lands and reflections are enabled game crash and I get [08:54:40] EXTENDED EXCEPTION(5:opengl_error): Error: 'Max instruction count exceeded' in file 'shaders/anim.vert' in load_vertex_program at actor_init.cpp (line 159). However turning off reflection helps</li><li>Nexuiz enabling GLSL and runnig game freez system</li><li>Sauerbraten enabling GLSL cause strange negative colors</li><li>Savage2 which requires shaders to run, renders white not textured objects</li> </ul><li>Sometimes when screensaver turns off monitor its not possible to turn it back on by any key or mouse, restart needed</li><li>In X switching to terminal and back with ctrl+alt+f? works but when You run any OpenGL full screen application then you can switch to terminal and switching back to X cause not reversable black screen, restart needed. </li> <li>I experienced also random freezes with UXA, but I doubt debian's xorg version 1.5.2 is aware of using dri2 so I stick to EXA.</li></ol>Configuration is kernel vanilla 2.6.26 and git eric's 2.6.27 Xorg 1.5.2 from debian (sid) libdrm master mesa master xf86-video-intel master dri2proto master I would like also to point out that GLSL is not only requited for games but latest blender is using it for realtime rendering. And they stated on their page that "Intel or VIA graphics cards, ATI Radeon cards older then the Xx00 series, and Nvidia Geforce cards olderthan the 6x00 series are unlikely to support this functionality well, unless through a slow software fallback" Is there any chance to change this ? My card is GM965 and it has full hardware support for OpenGL 2.1 but only on Windows.
