Hello! I have 2 identical Dell P2719H monitors. When I installed garuda, the default monitor setup in KDE settings → Display and Monitors worked perfectly (both side-by-side).
-
Today I cleaned my setup, so had to unplug and replug the monitors. Now both are showing up in KDE settings, but only one shows display, other shows black screen
(i.e. it’s not that the monitor isn’t detected…it is, but isn’t showing display.)
I can even move a window to the black monitor. But the monitor complains it isn’t receiving a signal. -
Things I tried:
a. Unplugging and replugging hdmi cable, power cable to monitor.
b.garuda-update
-
My GPU is an NVIDIA GTX 1650 Super. The working monitor is plugged in via displayport, and the black-screen one is plugged to the VGA port via an HDMI-to-VGA adapter.
