SUMMARY
On Kubuntu 25.10 With the KDE desktop:
After monitor sleeps and awakes, I get no logon screen. Instead I get this
work around screen:
1) Press ctrl+alt+F2.
2) In the terminal type "loginctl unlock-session 3".
3) Press ctrl+d.
4) Press ctrl+alt+f1.
Ctrl+alt+f2 does not bring up terminal. So I had to hard power off.
STEPS TO REPRODUCE
1. Allow monitor to sleep in Kubuntu 25.10 on a HDD or a the Kubuntu 25.10
64bit ISO flashed to a USB thumb drive and booted.
2. Attempt to get back on your desktop.
3. Try the 4 steps above.
Note: I upgraded KDE so this bug may not affect my system.
OBSERVED RESULT
I did get my login screen after doing step 1 above, but the screen was frozen.
EXPECTED RESULT
Logging back in to my desktop.
