By this do you mean xf86-video-nouveau?

At the moment you see LianLi kernel: nouveau 0000:01:00.0: gr: TRAP_CCACHE 00000001 [FAULT] your GPU has locked up.

Depending on your hardware, kernel and Xorg version you may have better luck updating one or the other but since you did not say what you are running exactly it is hard to tell. You can also peruse the kernel.org an freedesktop.org bugzilla and search for (probably numerous) reports with similar error messages.

Having neither proprietary NVidia nor xf86-video-nouveau drivers installed in my Leaps and TWs with various GeForce devices seems perfectly fine using the built-into-Xorg modesetting driver. People keep pointing out that the modesetting driver is only 2D, but I can't grok what 3D is supposed to bring to a two dimensional viewing surface. -- "The wise are known for their understanding, and pleasant words are persuasive."

Messages come from the kernel module nouveau...

Most nouveau GPU acceleration to be precise. This is delivered in concert by the kernel dri driver, mesa dri driver, and the X11 nouveau driver. If you remove some of these bits you lose the ability to accelerate rendering projection of 3d models on your 2d screen surface and the ability of the window manager to wobble your windows as you drag them across your screen but the stability of your graphics hardware will likely increase because most of its features will go unused.

HI

I get the occasional desktop freezes that needs a reboot and it looks like its down to a failing GPU or could it just be a bug? I get the following (just a subset) log records for nouveau. I also get various nouveau log records that reference things like kmail or akonadi_xxx - is this usual?

Any ideas?

It is normal. Nouveau is broken. You had to agree to it when you installed it.

I know its not well at times but the card is quite old now and i've been considering moving to AMD because of the consistent issues but i'm not sure if its the card failing or just nouveau having an issue

At the moment you see LianLi kernel: nouveau 0000:01:00.0: gr: TRAP_CCACHE 00000001 [FAULT] your GPU has locked up. Yep, i saw that. I thought the other messages referencing things like kmail and akonadi on nouveau logs records as strange

Depending on your hardware, kernel and Xorg version you may have better luck updating one or the other but since you did not say what you are running exactly it is hard to tell. You can also peruse the kernel.org an freedesktop.org bugzilla and search for (probably numerous) reports with similar error messages. I think i am as up-to-date with tumbleweed as i can be.

HTH

Michal Thanks
