Shades of Blue

I’m not entirely sure what’s special about my machine (T61 Thinkpad) that makes it lock up and reboot at least once per day without a warning (but sometimes after showing things in blue), but I’ve decided to blame something down the Xorg/Nouveau stack.
Interestingly, SSH’ing onto the sick machine isn’t much help either – when it freezes, cat /proc/kmsg, tail -f /var/log/Xorg.0.log and /var/log/messages, or gdb attached to /usr/bin/Xorg and gnome-shell don’t react anymore and don’t show any “additional” output either. Maybe it’s time to try Wayland? Can’t get much worse. :P

gnome-shell, now with more blue!

    OK, I also have a T61 Thinkpad and I had this issue starting with GNOME 3.6. This happened to me regularly and eventually my screen just went completely black, which meant afaik meant that my gpu had died. I switched my hdd to a new Thinkpad T61, and I still have the issue. It happens less frequently, though.

    Ah thanks for the hints!

    Yes, “lspci -v” tells me

    There could be many, many reasons, but my ThinkPad is plagued by this, which could be related:

    If it sounds lke your problem, search for “aharoni” to see what solved it.

    I’ve seen this with NVIDIA + Nouveau. .When eventually I got closed drivers to work, problem went away.

    What Amir says is partly true, I have a t420s and I used to have random kernel panics (which I didn’t since can’t remember when). I am not using nvidia tho, just regular intel graphics card. Blacklisting the mei_me module fixed my issues completely, ymmv
