Hi My laptop is an HP Pavilion 6000, with a G72M (GeForce Go 7400) chipset and the following CPU profile :
processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 14 model name : Genuine Intel(R) CPU T2250 @ 1.73GHz stepping : 8 cpu MHz : 800.000 cache size : 2048 KB ..... cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx constant_tsc arch_perfmon bts pni monitor est tm2 xtpr pdcm And objousvly I exprerienced the same problem. The latest driver 185.18.36 runs in the same way you described WITH and WITHOUT the workaround above (that looking at the code seems to be a test exclusion but does not solve the problem). I tested everything with kernels x.31-12 and x.31-13. I tested a new beta driver frome the NVIDIA site (the 190 beta) by a manual installation and it does not solve the problem so I reversed back to Ubuntu version (185). However I think this is a strange behavior because the glx module is properly installed and "glxinfo" returns a properly running extension : name of display: :0.0 display: :0 screen: 0 direct rendering: Yes server glx vendor string: NVIDIA Corporation .... glxgears runs properly and Google earth it's extremely fast, but there are problem with COMPIZ and with KDE also that does not use COMPIZ. I don't know why but probably this is due to an OPENGL feature that fall back to a software implementation if the CPU does not have PAT . I am in doubt about a kernel patch solution or a simple test removal, I think this is an architectural problem into the driver that dorce PAT instead of MTRR , and the new 190 driver still does not work.
