Comment 17 for bug 1267742

Hello,

I installed Ubuntu Trusty on an old tower yesterday, which has an integrated nvidia Geforce 7* so this is "nouveau" running on that machine, and after a while, when clicking on some menu the mouse suddenly freezes, and there is this strange look on the screen, looking a lot like what Elfy describes.

This happened after the distro was installed and updated. I have been able to install a few packages, but then it froze again. I could not use the SysRQ, it didn't work.

This morning on my own tower, which now runs Xenial I hit the same issue : which never happened before! But my tower has the same kind of nvidia internal GPU, an old Geforce 7, and I can't use the nvidia driver because it's now unable to display the resolution properly. So I thought the fault must be the nouveau driver (or firmware? I can't know that).
I also tried to ssh my tower using my laptop, but the frozen machine was unreachable.

I don't know why I can't attach more than one file here (using Firefox 44.0.1 but never could before). So I paste down here the 80 last lines of the most relevant syslog I could find, the one that has the timestamp from just before it froze, there is a part related to nouveau in it:
