Hi! I’m running Fedora 42 KDE Plasma and I’m running a dual-monitor setup. Both of them are external. Sometimes, after waking up from sleep, my right monitor takes a little longer to actually display the signal than the left one, and it seems that the “update brightness” command that powerdevil (I’m assuming that’s what’s responsible for dimming/brightening behavior) sends is sent too early, so it stays dim until I manually change the brightness. I was thinking of using a simple script to run after a short delay that’s triggered by the wakeup event in order to get around this, but I wanted to ask if there was a better way to address the issue? Also, if I were to go the script-after-wakeup route, is there a correct way for me to interface with powerdevil/KDE to control the brightness of a single monitor? I saw that you’re able to send a setBrightness command via qdbus but I didn’t see any documentation for the command that would target a single monitor when multiple are connected.
Thanks for any help!
