I don’t see an option to edit video cards in yast. I’m trying to get multiple screens but cant get to it. What should I do. Thanks for the help.
Welcome aslantek87. The tools for doing this actually depend on the video drivers in use, and the desktop environment.
For KDE: System Settings >> Display and Monitor
I’m not a Gnome user, but AFAIK there is the ‘gnome-display-properties’ applet. It should be available from one of the config menus.
If you’re using proprietary drivers, then there are proprietary config tools to assist. For example, nvidia uses the ‘nvidia-settings’ utility.
If you still have problems after this, please post your graphics hardware details, and desktop environment.
(Just the lines pertaining to your graphics card)
This command will show you what display devices are detected/connected:
and can also be used to dynamically re-configure your display devices (if using open-source drivers).
