Does Red Hat supports multiscreen configuration with GNOME3?
Issue
- How to configure dual monitors with separate screens (e.g., :0.0 and :0.1) in RHEL7, RHEL8 or RHEL9?
- GNOME desktop fails to render on second X11 screen(:0.1) when configured for two independent X screens.
- When using two monitors as two independent X11 screens ($DISPLAY = :0.0 and :0.1, respectively; sometimes called "Zaphod mode"), GNOME seems to ignore the second screen completely.
- GNOME desktop appears correctly on screen
:0.0
, but screen:0.1
is just a blank black canvas. If you force a window to the second monitor, it will render without any window manager decorations.
Environment
