Bug ID: 477323 Summary: Samsung Odyssey G5 (LC27G5xT) display does not initialize properly after logging in Classification: Plasma Product: KScreen Version: 5.27.9 Platform: Arch Linux OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: common Assignee: kscreen-bugs-n...@kde.org Reporter: vel...@protonmail.com Target Milestone: --- SUMMARY When booting my system with NVIDIA's DRM enabled, my Samsung Odyssey display only shows a black screen after logging in. Having the screen off while I boot and log in, and then turning the display on causes no significant issues and allows for the display to work like normal. STEPS TO REPRODUCE 1. Boot your system with a Samsung Odyssey G5 display connected 2. Log in to KDE 3. Observe that the display does not show a visual output OBSERVED RESULT The display is still recognized by Plasma as a display, and windows can still be moved to and from the display. Disabling or turning the display off freezes Plasma. I have experienced that the system unfreezes itself after a while, and that enabling or turning the display back on similarly freezes Plasma. EXPECTED RESULT The display having a visual output without needing to have the display off during boot and login. SOFTWARE/OS VERSIONS Linux/KDE Plasma: 6.6.2-zen1-1-zen (available in About System) KDE Plasma Version: 5.27.9 KDE Frameworks Version: 5.112.0 Qt Version: 5.15.11 ADDITIONAL INFORMATION I'm using SDDM in Wayland mode with kwin_wayland. I'm also using the Wayland version of Plasma, I haven't checked if the issue persists when using X11. -- You are receiving this mail because: You are watching all bug changes.
