We have been seemingly seeing this same bug on the Gentoo forums. So far only with GT 730 GPUs. Downgrading libdrm to 2.4.75 resolves the problems here also. https://forums.gentoo.org/viewtopic-t-1062172.html My hardware is a GK107GLM aka Quadro K1100M in an HP Zbook17, fwiw. Please report this issue upstream at https://bugs.freedesktop.org if no report already exists there. x11-libs/libdrm-2.4.79 is not in the tree anymore. Does it still happen with a more recent version? Has it been reported upstream? Somewhere along the line I got upgraded to 2.4.88 and the problem has not reproduced. Feel free to close this bug.

I can't close it, but you as the author should be able to. Just mark it as RESOLVED-OBSOLETE. No longer reproducible. |
Recent update brought in 337 packages, after which I could no longer log in graphically. Plasma's splash screen would display, or Xfce's desktop would briefly be visible, then X would crash and drop back to the login manager. { Due to the number of new packages, including nouveau, spent quite a while poking around at other possibilities before following the Xorg single-computer gdb script procedure to get a backtrace. } Reproducible: Always Steps to Reproduce: 1. Install xorg-server-1.{18,19}.* with xf86-video-nouveau-1.0.{13,14} and libdrm-2.4.79 2. Reboot or restart X 3. Login Actual Results: X crash with truncated backtrace in Xorg.0.log.old until use flag 'unwind' was turned on. Then figured out that I was seeing X's signal handler trace. Followed x.org's instructions to replace /usr/bin/X with a gdb script. Output attached showing nouveau calling into libdrm, and failing at xf86drmMode.c:923. Expected Results: Desktop appears, in either Xfce4 or plasma-desktop. Reverting to libdrm-2.4.75 restored proper operation.
