Display configuration not responding
+++ This bug was initially created as a clone of Bug #514106 +++
SUMMARY
This bug is a regression from Plasma 6.3 Kubuntu the 25.04. Since upgrading
to Kubuntu 25.10 Plasma 6.4 the Dispaly configuration panel and especially the
screen rotation and sceen orientation freatures continually lapse and get stuck
in incorrect properties. The Display Configuration widget itself fails on
start-up (lomg delay) and appears to reset before showing.
These features worked promptly and smoothly for the previous Kubuntu 25.04 on
this, the same laptop.
STEPS TO REPRODUCE
1. Begin with a suspended laptop (Kubuntu)
2. Open laptop screen from Suspend, with screen vertical and keyboard in your
lap (normal)
3. The 25.10 screen and keyboard seem to be locked for a good amount of time,
more than a minute.
* Every previouos version of Kubuntu until 25.04 the KDE screen refreshed
almost immediately on awaken.
3. The screen is stuck in up-side-down orientation when SLEEP was issued on
upside-down orientation.
* In the Plasma 6.4 the screen flipped right-way-up almost immediately
4. The user must use the upside-down screen to get started
5. Open the launcher and select 'Display Configuration' (up-side-down)
6. 'Display Configuration' shows as "Not Responding"
* see screenshot: Display-Conmfiguration.01:Not-Responding
* The PC is locked during this time. Keys, mouse, touchpad and touchscreen
do not respond.
* Including that command line is not working either until the Display
Configuration comes up.
7. When the Display Configuration finally comes-up you, the "Automatic" screen
orientation sub-section is not present.
* see screenshot: Display-Conmfiguration.02:Automatic-Missing
8. When you use APPLY the PC is locked-up and there is a very noticible delay
OBSERVED RESULT
As described doesabove
1. Screen orientation is upside-down
2. Display Configruation lost and fields missing
3. Lock-up or no response during APPLY actions.
4. Display Configuration settings fail to persist
When I originally submitted this bug it was closed as multiple issues. That is
incorrect. There is ONE issue the Display Config does not persist and
consequent behaviours are symptoms.
EXPECTED RESULT
I would like everyting to work nice and smoothly as it did with Plasma 6.3 /
Kubuntu 25.04
* The display configuration and screen rotation ALL work as long as the PC is
active so all drivers and such are running as intended.
* The screen roation and other fuctions Actually Work when the Dispklay
Configuration has been "restored" by manually working the screens.
