Bug ID: 494815 Summary: Display randomly has low brightness (one or both monitors) Classification: Plasma Product: Powerdevil Version: 6.2.0 Platform: Arch Linux OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: plasma-b...@kde.org Reporter: hira...@gmail.com CC: natalie_clar...@yahoo.de Target Milestone: --- SUMMARY Often one or both of my monitors have very low brightness on session start. STEPS TO REPRODUCE 0. Use Wayland. 1. Log in to a session from SDDM. 2. If monitors have normal brightness, log out and go to 1. OBSERVED RESULT One or both monitors have very low brightness. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.2.0 KDE Frameworks Version: 6.7.0 Qt Version: 6.8.0 Kernel Version: 6.11.3-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 16 × Intel® Core™ i9-9900K CPU @ 3.60GHz Memory: 31.1 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 3090/PCIe/SSE2 Also, this is a desktop system with two monitors connected. ADDITIONAL INFORMATION 1. Started once I updated to KDE 6.2. 2. I could not reproduce it on X, only happens on Wayland. 3. This is NOT likely related to ddcutil - the value it sets matches the value I see in monitor. Unfortunately I have not found a way to correct the problem even after logging in, except to log out and log in again, or reboot, and hope for the best. I am unsure if it is an issue with powerdevil, but brightness appears to be related to it? -- You are receiving this mail because: You are watching all bug changes.
