This seems to be a hardware (firmware) issue. It only happens with one monitor and only when connected via HDMI. |
Created attachment 156733 [details] journalctl output when the bug occurs SUMMARY On 5.27.0 I had the kded5 crashes after the monitor went to sleep or was manually powered off. After upgrade to 5.27.1 while that no longer happens, now there is another problem with random behavior after the monitor attempts to go to sleep or is powered off. On my normal account when typically the monitor should go to sleep instead the monitor wakes back up but most of my desktop icons are missing, sometimes terminal output is messed up, etc. For the general problem though I'll discuss what happens with a brand new account with entirely default configuration. STEPS TO REPRODUCE 1. Create a new account 2. Let the screen timeout. (Either the default 10 minutes or do "xset dpms 5 6 7" to speed things up 3. At first everything is fine. Monitor goes to sleep. 4. Open a konsole and run "sudo journalctl -f" 5. Let the monitor try to go to sleep again, it won't. (Usually, sometimes I've had to move back to the konsole that I ran xset in, or do something to start the bug.) OBSERVED RESULT The monitor will not go to sleep and instead just before it should the desktop will wake back up. There may be corruption of open apps and the Desktop. The journalctl fills with lines from kscreen like in the attachment. This journalctl output does not occur when the monitor goes to sleep and wakes back up correctly. EXPECTED RESULT The monitor should go to sleep. When the session is resumed the desktop and all applications should be as they were before the monitor went to sleep. The logs should not fill with information about the screen after every sleep/wake cycle.
