Random Freezes

So I'm using the nouveau driver on an nvidia gtx 660 along with gnome DE. The video output crashes randmoly (mainly when using browsers either firefox or chromium) but the sound continues to play normally (e.g music). I've managed to ssh to the machine and below is the dmesg output since the last crash happened:

Re: Random Freezes

I run into this regularly when watching more than a single short video. Unfortunately all of the advice (i.e. the top-voted answers or posts that mark the issue as "[Solved]") says to install the proprietary NVidia drivers, which I would rather not do.

Re: Random Freezes

Does it work if you opt for xorg instead of using Wayland?

I use X11 exclusively, and so I've always encountered this crash with it.

Re: Random Freezes

And you get the exact same error ? FWIW additional things to try are running xorg with/without xf86-video-nouveau

Sorry, not the exact same error, but the same symptoms. I didn't catch the dmesg output last time, but I'll try to post it next time.

I know I see a line like:

[DRM] GPU lockup - switching to software fbcon
