I'm reporting this same issue from another distro (Arch in my case). I've added the journal file with the drm.debug parameter. Hope it helps.
A summary of my issues just in case: - Lenovo T480 Laptop - Using in combination with Lenovo USB-C thunderbolt 3 dock to drive 2 screens (That are connected through HDMI if that matters) - When logged into a GNOME Wayland session and waking up from a suspend the screens don't come back on. - My logitech MX Master mouse doesn't respond anymore - My Bluetooth keyboard doesn't respond anymore - Unplugging from Thunderbolt dock makes the system run fine again when it's just the Laptop (bluetooth keyboard and mouse still dont work tho) - Replugging to dock causes same issues as I had after waking from suspend. ** Attachment added: "Output of journalctl -b0 after laptop woke up from suspend" https://bugs.launchpad.net/mutter/+bug/1968040/+attachment/5672555/+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: [i915] 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
