I think there is something wrong with gdm3/wayland/NVIDIA proprietary driver. If I config gdm3 as default display manager, when rebooted, I have a black screen but I'm able to switch to other tty by press crtl-alt-f2 to f7. Then I edit /etc/gdm3/custom.conf uncomment line 7th to WaylandEnable=false then rebooted, then I have system hange after reboot :(. It seems that the OS is stuck in gdm3 service. I tried to change/regenerate/delete xorg.conf but it simply doesn't work. So I think xorg.conf is not the root cause for me.
If I uninstall all nvidia stubs and install nouveau xorg driver, the system is able to boot to graphic shell with gdm3 as a display manager. Unfortunately, the nouveau driver does not support CUDA computing framework and the performance of this driver is very poor when compare to the binary one. If I config to use lightdm as default DM, it works with NVIDIA binary driver, but this is not what I expected. I expect the system have to work with gdm3, ubuntu-xorg session and NVIDIA proprietary driver. I have an app that need xorg session and CUDA, so I must install NVIDIA binary driver. PS: If you are able to boot to graphic mode but stuck with login loop, you could try to delete the ~/.Xauthority file then reboot. It worked for me. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1752053 Title: nvidia-390 fails to boot graphical display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1752053/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
