Title:
Empty desktop background after screen unlock - only dock with app
icons and top panel, cannot see any app
Status in gnome-shell package in Ubuntu:
Expired
Bug description:
Steps to reproduce (intermittently, ~1 per 10 times):
1. Leave the computer until the screen is blank - two monitors, no
multimonitor plugin
2. Move the mouse to unblank the screen
3. Drag lock screen to top + enter password
Actual results
- Ubuntu dock is visible (with app icons)
- Top panel is visible, but with limited options (e.g. no "Sleep" button, no
app indicators)
- Empty desktop background
- Clicking the app icon does nothing - there is some animation effect, but it
looks like the application would be 'behind' the background
- Clicking "Applications" menu animates but then disappear as well
Partial workaround:
1. Ctrl-Alt-F1
2. Choose the same user and enter password
3. You'll come back to the "empty desktop". But in a few seconds applications
appear with a few limitations:
a) Top panel features are still limited (no sleep/power off buttons in menu,
no app indicators)
b) Ubuntu dock shows different set of apps on each 1st and 2nd monitor
Might be related to one of the stack traces in journalctl -first is probably
when the screen was locked, second when unclodked
