Bug ID: 470383 Summary: Displays connected through USB-C Dock give Black Display Classification: Plasma Product: kwin Version: 5.27.5 Platform: openSUSE OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: wayland-generic Assignee: kwin-bugs-n...@kde.org Reporter: sfal...@cloverleaf-linux.org Target Milestone: --- Using a Lenovo Thinkpad T16 AMD, and Lenovo Universal USB-C Dock, a plasma-wayland session gives me no output to the displays. kscreen *sees* the displays there, but the displays remain blank. This behavior is the same whether I have the dock and displays plugged in while booting, or if I plug the dock into an already booted plasma-wayland session. STEPS TO REPRODUCE 1. Plug displays via displayport cables into USB-C Dock 2. Plug Dock into Laptop OBSERVED RESULT No Output to dock connected displays, but all other dock functions work (audio passthrough, mouse/keyboard, etc), Kscreen reports the displays are there and enabled, but displays remain blank. EXPECTED RESULT Output of Graphical desktop to dock attached displays SOFTWARE/OS VERSIONS Linux/KDE Plasma: openSUSE Tumbleweed (available in About System) KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.106.0 Qt Version: 5.5.19 ADDITIONAL INFORMATION This behavior is the same for me on both openSUSE Tumbleweed, and Fedora 38, so it doesn't appear to be a distro specific issue. Not that it matters to wayland, but using plasma-x11 also is problematic. The Dock works *fine* and as expected in Gnome 44, for both X11 and Wayland sessions, on both openSUSE and Fedora -- You are receiving this mail because: You are watching all bug changes.
