[Bug 1925344] Re: [nvidia] Session not started after reboot (black screen) - requires switching tty back and forth
I believe I am experiencing this on 20.04 > (EE) open /dev/dri/card0: No such file or directory The problem seems to be that gdm-wait-for-drm doesn't work for (muxless) dual GPU laptops when using the dGPU. GDM will start when only card1 is available, *both* card0 and card1 need to be available before starting X. (As a quick hack, I am using `ExecStartPre=/bin/sleep 1` to give drm enough time before starting GDM.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1925344 Title: [nvidia] Session not started after reboot (black screen) - requires switching tty back and forth To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1925344/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
