Public bug reported: Upgraded to Cosmic Cuttlefish a little over a week ago, Now every time that the computer locks the screen, the screen is mostly blank and shows only the launchpad with favorites at the left, and the status icons at the top right. Clicking on the apps shows the app for a moment before being hidden again. The system drop down menu shows the usual information except the system tools / lock / power icons with a pause button displayed in their place but all is disabled except the pause button which suspends the computer. Upon waking again the computer is still locked. Have not discovered a key sequence that does anything when in this state. Cannot even switch virtual terminals or desktops. My only solution has been to power off the machine and do a hard reboot.
I expected the lock screen to blank out the screen as it did in the previous release and show a login My computer is a Lenovo Thinkpad T-410 with 6Gb RAM.
