Hi team and all. I'm stuck with a similar issue. The solution with MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 helped me! Thanks guys!
I created logs for you (without kernel parameter: drm.debug=0xff, can't find how do it). If somebody wants to help collect logs it easy perform without working screen: 1. Disable authorization after sleep in the settings->privacy->screen. 2. Send Ubuntu sleep. 3. Start Ubuntu. Now goes steps with a black screen but PC looks working: 1. Ctrl + Alt + T for open terminal. 2. Write journalctl -b0 > journal.txt ( I used the UP key for using the last terminal command). 3. restart your PC. 4. journal.txt will be in the HOME directory. Good luck all us! ** Attachment added: "journal.txt" https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1968040/+attachment/5663333/+files/journal.txt ** Attachment removed: "journal.txt" https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1968040/+attachment/5663331/+files/journal.txt -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1968040 Title: Blanked screen doesn't wake up after locking [drmModeAtomicCommit: Argument invalide] [drmModeAtomicCommit: Invalid argument] To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1968040/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
