Default Re: Linux 2.6.29, nvidia 177.82-180.41 = glxgears: 3 FPS

Is "direct rendering enabled"?

If you have "direct rendering: yes", edit /var/log/dmesg and search for messages like this:
Code:
 IRQ XX IRQF_DISABLED is not guaranteed on shared IRQs
Many users have reported problems with 2.6.29 and IRQF SHARED/DISABLED; in some cases, this problem affects nVidia cards too.

In my case, after I have switched to 2.6.29, I get the message (at boot):
Code:
IRQ 18 SAA7133: IRQF_DISABLED is not guaranteed on shared IRQs
and my DVB-T card does not work!
