Public bug reported: I recently updated to Ubuntu 24.04 and I noticed that the Gnome Shell frequently crashes when I disconnect the USB-C cable that connects by laptop to my screen.
This is sporadic and not easy to reproduce, but when it happens, the sequence usually is: 1. Run Ubuntu 24.04 with Gnome desktop on a laptop, connected to a screen with USB-C cable 2. Use it for several hours. I am not able to reproduce this issue directly after startup. 3. Disconnect the USB-C cable Expected result: Gnome session should continue on laptop screen after cable disconnect Actual result: Gnome session crashes and user is presented with Gnome login screen The journald logs from the time of each crash consistently shows these log lines: ``` Jan 21 16:07:00 u513b3c1e6b045d.ant.amazon.com kernel: usb 3-8: USB disconnect, device number 10 Jan 21 16:07:00 u513b3c1e6b045d.ant.amazon.com kernel: usb 3-8.1: USB disconnect, device number 11 Jan 21 16:07:00 u513b3c1e6b045d.ant.amazon.com kernel: usb 2-1: USB disconnect, device number 4 Jan 21 16:07:00 u513b3c1e6b045d.ant.amazon.com kernel: r8152-cfgselector 2-1.2: USB disconnect, device number 5 ...
