On one of the T7500 ubuntu 17.10 boxes (nvidia 340 package, Quadro K5000 card), I did sudo "do-release-upgrade -d". Went fine, but on reboot, the desktop would come up for about ten seconds, then the system would shut down. Did systemctl set-default multi-user.target then removed all traces of the proprietary driver with sudo apt remove --purge nvidia-340 nvidia-opencl-icd-340 nvidia-settings nvidia-384 nvidia-opencl-icd-384 nvidia-prime libcuda1-340 and rebooted. Logging in to the console and running 'startx' reproduces the problem reliably, and does not shut down the system. Installing lwm, and a .xinitrc that started an xterm, let startx succeed, and the system was stable running firefox, so it's not an obvious graphics problem. /var/log/syslog says Apr 25 09:59:41 rbb-ubu1710-3 org.gnome.Shell.desktop[3936]: ** Apr 25 09:59:41 rbb-ubu1710-3 org.gnome.Shell.desktop[3936]: mutter:ERROR:x11/iconcache.c:303:standard_pict_format_for_depth: code should not be reached Apr 25 09:59:41 rbb-ubu1710-3 org.gnome.Shell.desktop[3936]: == Stack trace for context 0x556d30f3c4c0 == Apr 25 09:59:41 rbb-ubu1710-3 dbus-daemon[690]: [system] Successfully activated service 'org.freedesktop.fwupd' Apr 25 09:59:41 rbb-ubu1710-3 systemd[1]: Started Firmware update daemon.
