Description Christian Stadelmann 2014-09-29 21:45:02 UTC

Description of problem:
When switching from gnome-session-wayland-session to tty using Ctrl+Alt+F<n> and back gnome-session gets hidden


Version-Release number of selected component (if applicable):
gdm 3.14.0-1.fc21
gnome-session-wayland-session 3.14.0-1.fc21
gnome-shell 3.14.0-2.fc21
wayland 1.6.0-1.fc21
xorg-x11-server-Xwayland 1.16.0-10.fc21

How reproducible:
always

Steps to Reproduce:
1. log into gnome-session (wayland) from GDM
2. switch to tty
3. switch back to gnome-session

Actual results:
gnome-session is not visible any more, seems gone. gdm shows login screen (not lock screen)

Expected results:
gnome-session should come back or at least gdm lock screen be visible

Additional info:
No crash happens, no logout happens. gnome-session (wayland) still runs in background including all open applications.

Comment 1 Christian Stadelmann 2014-12-14 15:55:47 UTC

With F21 out this sometimes happens to regular gnome-session (without using wayland). Any ideas or progress on this?

I am not using any proprietary GPU driver, just the default one for Intel iGPUs.

Comment 2 Christian Stadelmann 2015-03-24 17:45:45 UTC

This bug is still present in F22 Alpha. And it also affects GDM.
In short: Every time I switch from a GDM or gnome-shell wayland display somewhere to a tty or another GDM or gnome-shell display, the UI freezes. I can't use the computer any more.
Kernel doesn't freeze, sysrq keys still work.
This renders gdm on wayland completely useless since I can't even login.

Additional info:
I don't have plymouth installed.

Comment 3 Ray Strode [halfline] 2015-03-24 19:07:40 UTC

I think this got fixed shortly after alpha. Please try the latest updates.

Comment 4 Christian Stadelmann 2015-03-25 14:51:38 UTC

Can you please be more specific? I updated to updates-testing as of today and the problem still persists. I have
gdm 3.15.92-1
gnome-shell 3.15.92-2
wayland 1.7.0-1
installed.

Comment 5 Christian Stadelmann 2015-04-10 07:50:55 UTC

I think you are right. It can not reproduce this issue any more.
