Thanks. These messages look the most suspicious to me: Mai 04 11:04:24 mamba kernel: i915 0000:00:02.0: [drm] *ERROR* mstb 00000000caa481c4 port 1: DPCD read on addr 0x4b0 for 1 bytes NAKed Mai 04 11:04:24 mamba kernel: i915 0000:00:02.0: [drm] *ERROR* mstb 00000000caa481c4 port 2: DPCD read on addr 0x4b0 for 1 bytes NAKed Mai 04 11:04:27 mamba kernel: xhci_hcd 0000:2d:00.0: xHC error in resume, USBSTS 0x411, Reinit Mai 04 11:04:27 mamba kernel: usb usb3: root hub lost power or was reset Mai 04 11:04:27 mamba kernel: usb usb4: root hub lost power or was reset ...

It's certainly possible that if gnome-shell is expecting a working monitor then such kernel/hardware/dock/firmware bugs might make it appear to freeze, as it waits forever. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1971536 Title: Gnome shell freezes when plugging in external display Status in gnome-shell package in Ubuntu: Incomplete Bug description: I have a Lenovo Thinkpad X1 Yoga with Ubuntu 22.04 and a dock for it. If the laptop is in the dock and I plug a monitor into the display port gnome shell freezes. When this happens I can still go to other ttys. This exact setup used to work for Ubuntu 20.04 so I assume it must be connected to wayland somehow. lsb_release -rd Description: Ubuntu 22.04 LTS Release: 22.04 apt-cache policy gnome-shell gnome-shell: Installed: 42.0-2ubuntu1 Candidate: 42.0-2ubuntu1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1971536/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
