| From: Jim Ruxton via talk <talk@gtalug.org> | If I could ssh in via Ethernet while it is crashed what should I look for? My | card is also dual Intel/Nvidia. Magic SysRq works for me as a way to reboot | the machine. I have filed a bug report with Bugzilla. If i get any results | there I will post them here. Maybe you want to add to the Bug report? | https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1771661 I don't run Ubuntu, so this is just guess-work. 1) I detest running a proprietary driver. You could just use the Intel driver. That might well work. What have you got to lose? 2) Is bumblebee still the way to support these intel/nvidia chimera systems? 3) guess: GDM probably is wayland-only. Can you switch to LightDM, for example? That's what Ubuntu used to use. ==== when SSHed into your hung system 4) see what processes are running (ps) 5) see what the last bunch of lines from dmesg say. The problem may well be reported there. 6) I think ubuntu now uses journald. So look at the output of "journalctl -b". Focus on the last page or two of output, but do scan it all. 7) look at the most recent file in your home directory "ls -latr'. You might find an X error log. ~/.xsession-errors, I think 8) anywhere else the clues lead you.
