Attaching Viewsonic VX2453MH-LED via USB-C/HDMI-Adapter does not work
Hi,
I am currently using a Librem 5 Evergreen and try to connect it to an external screen Viewsonic VX2453MH-LED. The screen is not always detected, but when it gets detected, I can see some edid data (only checked via cat, contained VX2453 Series, so obviously related to the screen) and modes got detected. However, I cannot get any output on the screen. I mainly tested via the adapter delivered together with the Pinephone (not Pro), but also tried the Digitus DA70882 docking station, both work fine with a Dell notebook.
I currently use stock PureOS with 6.1.0-1-librem5 kernel.
When executing echo 0x2f > /sys/module/drm/parameters/debug
and connecting the screen, I get the attached output. Would it make sense to use the kernel currently in development? Or should I get the l5devkit and try whether it works there? screen-connect-hdmi-viewsonic-VX2453-Series
