[Bug 2003031] Re: [i915] Using gnome-shell with a USB-C dock causes the kernel to log "adding CRTC not allowed without modesets" and crashes in drm_atomic_check_only

Below are the updated patches for each release.

Hey everyone, Today the changes were merged upstream after I did some slight modifications to the patch last week.

[Bug 2020641] Re: Installing or removing apps through snap-store launches another gdm session
Hello Everyone, It seems that the regression that appeared in the autopkgtest for Jammy has been resolved and now the test succeeds on all architectures. However the test for Lunar fails due to an issue related to the autopkgtest script. The test in question that is failing is the "testcase_nvme_basic" test and the issue seems to be related to the test itself since the logs report a segfault occurring in the "test- functions" script. QEMU is also reporting multiple warnings about the use of a deprecated variable name being used by the test. The logs of the error can be found here: https://pastebin.canonical.com/p/cTc2RQN84m/ Also this error is occurring very early on in the boot phase (before the kernel is even up and running) so I cannot see the GDM patch being the reason or the cause of the issue. I would love for someone to chime in and confirm if my analysis is correct or not.

** Description changed: gdm3 version: 42.0-1ubuntu7.22.04.2 Ubuntu version: Ubuntu 22.04.2 LTS [Description] Installing or removing snap packages through NICE DCV on AWS will cause the user to be kicked out of their session. The issue happens on machines running nvidia GPUs (passed through to a VM) with the GRID driver installed as well as the normal nvidia driver. [Steps to reproduce] Simply install or remove any snap through the snap store will trigger the issue, for example: $ snap install skype also running any of the following commands will also trigger the issue: $ snap connect skype:opengl :opengl $ snap disconnect skype:opengl :opengl $ snap connect skype:camera :camera $ snap disconnect skype:camera :camera After further investigation I was able to pin down the issue to udev and could reproduce the issue by running the following command: $ sudo udevadm trigger --parent-match=/sys/devices/pci:00/:00:1e.0/drm/card0 where "/sys/devices/pci:00/:00:1e.0/drm/card0" corresponds to the nvidia GPU of my instance. A more generic way of triggering the issue would be running: $ sudo udevadm trigger [Solution] I have investigated the issue and discovered that it lies within GDM3 in the "udev_is_settled" function (daemon/gdm-local-display-factory.c). In the case where the udev is settled the line "g_clear_signal_handler (>uevent_handler_id, factory->gudev_client);" at the end of the function is triggered however this is not the case when the function returns early and will lead to the user being logged out. In its current implementation there are three different return points before "g_clear_signal_handler" is executed where the udev devices would already have settled. I have written a patch that fixes this issue by making sure the function "g_clear_signal_handler" is executed in all cases for which the udev is settled. [possible regressions] Excessive clearing of the signal handler might cause a case where it is not being re-initialized the next time it is needed. + + [Base test plan] + + This test plan is to make sure the issue listed in the description + section is fixed. + + 1.
