vnc does not respond after reboot (nvidia driver) #1

Open pieper opened 3 years ago

pieper commented 3 years ago

After reboot the noVNC endpoint will not connect.

Looking at systemctl the slicerX service does start, so none of the down-stream services start (x11vnc, mwm, slicer...).

Running nvidia-smi says it cannot connect to driver.

Workaround: Based on this suggestion, running sudo apt purge *nvidia*; sudo apt autoremove; sudo ubuntu-drivers autoinstall and rebooting worked but also required manual restart of slicerX and x11vnc after boot.

Still needed: need to be able to cleanly reboot without losing driver state.

The workaround is not consistent, so more research is needed.

Restarting via systemctl is not working for slicerX but running sudo /usr/bin/xinit -- +extension GLX in a tmux session does work. Then doing sudo systemctl restart x11vnc allows connection.
