Brightness control slider restored following reboot of system
After I reboot, the brightness control slider is present on the
System Settings -> Display & Monitor pane.
And I am also able to adjust screen brightness via the keyboard keys.
There were fixes related to this in Plasma 6.3 with ddcutil 2.2.1 or later Are you still experiencing this bug with ddcutil 2.2.1 or later? (In reply to TraceyC from comment #2) > There were fixes related to this in Plasma 6.3 with ddcutil 2.2.1 or later > Are you still experiencing this bug with ddcutil 2.2.1 or later? I just installed ddcutil 2.2.1-1.fc42 I'll run my system for a few days to test and see if I can still reproduce the problem. The problem is extant as of today's observations. |
Created attachment 182074 [details] Brightness control slider gone from settings screen SUMMARY Cannot control screen brightness. STEPS TO REPRODUCE 1. Nothing... the problem manifests periodically, presumably randomly. 2. When the problem occurs, I try to hit the brightness controls (less brightness, more brightness) on my keyboard, but there is no response from the display. 3. Alternatively, I go to the System Settings -> Display Configuration pane. There is no "Brightness control" slider. When the problem occurs, this slider has disappeared. 4. I have to reboot my system to clear the problem. OBSERVED RESULT No change in brightness occurs. The "Brightness control" on the System Settings -> Display Configuration pane has disappeared. EXPECTED RESULT I should be able to adjust the screen brightness up or down by either hitting the brightness control keys on my keyboard OR via the System Settings -> Display Configuration pane.

If I update my system via dnf, I ALWAYS reboot immediately to avoid conflict between incompatible changes to various shared objects or applications. I've attached screen grabs.
