Public bug reported:
Binary package hint: xserver-xorg-video-intel
Laptop Lenovo G550, video card : Mesa DRI Mobile Intel® GM45 Express
Chipset GEM 20091221 2009Q4 x86/MMX/SSE2
System doesn't fully support it. The display works fine, but 3D
applications run very slow(and always with errors in textures), or
textures in 3D games flashing or graphic-polygons disappear. Under
Fedora and Windows XP, everything works fine.
lshw-gtk says for video card "this device hasn't been claimed". Some
games detects my card as Nvidia or X11 Configured ?
Wine for most of games reports 1-2 times per second:
GL_FRAMEBUFFER_UNSUPPORTED and GL_INVALID_FRAMEBUFFER_OPERATION related
errors
