This issue is not 100% reproducible. It happens after 50% of reboots and I can't figure out regularity.
But I managed to contrive a workaround! ``` $ cat /etc/systemd/system/fix-graphics-after-boot.service [Unit] Description=Restart display-manager if amdgpu initialization failed After=display-manager.service JobRunningTimeoutSec=30 [Install] WantedBy=graphical.target [Service] Type=oneshot ExecCondition=/usr/bin/dash -c "journalctl -fk | grep -Fm1 'amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize parser'" ExecStart=/usr/bin/systemctl restart display-manager.service ``` After you've created such file don't forget to enable it: systemctl enable fix-graphics-after-boot.service The idea of this service is to scan kernel logs for 30 seconds after display-manager is started and if there is signs that amdgpu initialization failed then restart display-manager. Works for me! Though adds 15 seconds delay for 50% of boots. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870971 Title: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1870971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
