--- Comment #5 from d3vilguard <g.igna...@outlook.com> --- (In reply to Natalie Clarius from comment #1) > I've encountered this as well today, haven't yet figured out under what > condition this happens. final update 6.2 is affected too. Issue occurs if I leave the monitors off for at least a few hours (set in power menu to turn off after 20 minutes automatically). CURRENT BEHAVIOR: - 6.2 will be able to control monitor brightness but now the monitor (ACER) that it looses control over is dim. There is some level of brightness control but the monitor is visually very dim, compared to the monitor that plasma has no problems with. - removing powerdevil (for testing) leads to both monitors being dim after a reboot. This led me to the conclusion that powerdevil after some time looses control over one of the monitors. In 6.1 it lost full control, in 6.2 in seems to be partial (due to the some level of brightness control, yet being very dim). - Restarting powerdevil fixes the issue (fixing as in temporary untill it reoccurs): systemctl --user restart plasma-powerdevil.service Video with the latest findings: https://www.youtube.com/watch?v=sV6BkxrI1Gg Video doesn't show me playing around with monitor brightness. Dim/ACER monitor will get a bit brighter but still will be very dim. Restarting powerdevil, like shown in the video, fixes that. p.s. sorry for the other messages here. Was trying to keep notes of my findings for myself included. -- You are receiving this mail because: You are watching all bug changes.
