Hi all,

I've been having some issues with nouveau drivers.

After everything working fine for a few minutes (sometimes a couple of hours), gnome-shell text and icons become garbled. I need to refresh gnome-shell and sometimes it freezes and I need to restart the environment.

I'm using the latest kernel 3.7.8-202.fc18.x86_64
It worked fine for a couple of days with two previous kernels and then broke again.

I've tried to use NVidia propietary drivers, but they didn't work. I think my card is not supported (I'm not sure of which video card I have, this is a company computer and nobody knows), it is reported as NV50.

So far, I've been able to locate this errors:

any help is welcome.

I have an old laptop on which I installed F-18. On that laptop, the nouveau driver would not work, and I could not get a usable screen with any 3.7 kernel until I switched to the nv driver and abandoned the nouveau one. (Well, setting the kernel options to nomodeset xdriver=vesa gave me a working (all be it distorted) display.)

On the other hand, those messages seem to suggest that the page memory on the nVidia board may be faulty. Do you have have any spare video boards you could use to check the hardware? (Of course a "company computer" is more likely to have an "on board" video chip set, and no option for hardware upgrades.)

You are right about the no option for hardware upgrades. I should mention that I'm using a iMac (10,0).

The odd thing is that it worked fined a couple of kernels upgrades back (3.7.4 or 3.7.3, don't remember) and since then it's broken again (it was broken when I upgraded to FC18 from FC17.
