This is a known major bug and has already been reported. https://mirror.git.trinitydesktop.org/gitea/TDE/tdebase/issues/163 Unfortunately we still don't know the cause. Apparently the display configuration module somehow messes up while trying to set the settings with XRandR. Meanwhile you can use another tool like LXrandr or the CLI. I have also written a small TDE app for my own needs with three simple options, disable HDMI, mirror and extend (side of screen selectable). It is a wrapper around the xrandr tool so it shouldn't mess up anything: https://github.com/blu256/tde-easy-projector -- Philippe M. -------- Αρχικό Μήνυμα -------- Την 6/6/24 10:51 μ.μ., Thierry de Coulon via tde-users ο/η <users@xxxxxxxxxxxxxxxxxx> έγραψε: > I use a Lenovo X390, MX-Linux 21.3, with one user using xfce (the "original" > DE) and the other using TDE. > > When I plug in HDMI (for a beamer, in this case), xfce can easily be set up to > mirror the display. > > When I use TDE and connect the Beamer (seen as HDMI-2), TDE automatically > extends my screen to the beamer. xrandr -- output HDMI-2 --same-as eDP1 > (where eDP-1 is the internal screen) does mirror the screen, but it remains > extended. > > Now if I run "Configure Displays" and select "Enable local Display control for > this session" (which was not activated), I do get the mirroring I am looking > for.
