GNOME Shell seemingly locked up at login

[Will Cooke]

In 19.10, and also running the X PPA from http://ppa.launchpad.net/canonical-x/x-staging/ubuntu

When I logged in (after having attached a Bluetooth speaker in order to test if it was being reconnected correctly) GNOME Shell isn't responding to mouse or keyboard input.

The clock continues to tell the right time, and the mouse moves around the screen and is repainted correctly.

Fix in this ppa https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/3814/ please test :)

[Adam Conrad (adconrad)]

Is there an intent to get this into eoan in the next few hours and respin beta for it?

[Marco Trevisan (Treviño) (3v1n0)]

Considering the bug is particularly bad, it probably makes sense.

Package in the ppa is enough for being sponsored (once fixed the changelog)
if there's rush.

[Olivier Tilloy (osomon)]

I tested the package from silo 3814 in an eoan VM where I can observe the hang very reliably, and the problem appears to be gone (rebooted the machine a dozen of times or so without an issue).

+1 from me (but as pointed out already the changelog entry needs to be fixed, it doesn't mention the patch name).

[Rick Gatewood (george-gatewood)]

I had this issue in VM consistently when loggin in with Xorg. No problems with Wayland.
Tried the patch from above ppa and it appears to have solved problem.

Will do physical install on laptop to verify

[Jane Atkinson (irihapeti)]

PPA package is also working in an eoan QEMU/KVM vm which was locking up with the standard packages.

I also ran into a lockup problem on the ISO file when installing. Not sure if it's related to this or not.
