Display cable issues often cause subtle detection problems which can come and go. You might have full resolution available at boot, and then start to have problems when the monitor tries to wake from sleep.
The literal meaning of "[drm] Cannot find any crtc or sizes" is that it can't find the display hardware or any display modes. So this is a poorly worded error message. More likely and more simply it means it can't detect any monitor. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2168275 Title: [amdgpu] Boots to blank screen, monitor turns off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-7.0/+bug/2168275/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
