We are testing a new computer and have discovered something irritating. It claims there is a second (or more) display even though there is only one connected. So the OS install windows are shown off screen. Well, off the one that really has a display connected.
We do not see in the BIOS how to make the system do the right thing (e.g., only enable one display connector). And we are a bit surprised that the displays are thought to be active when there is no connected display.
It seems that the install GUI is the one that gets fooled. We are still testing to verify that.
Is there a kernel command line option that limits graphics to the main display? Our thought is that we could use that during the OS install.
Is _anything_ attached to any of the computer's display connectors? A projector, a TV set, a connector-convertor, an unused display cable? Is this a desktop or a laptop? If it's a desktop, is it possible that you have 2 different connections to a single screen? (E.g. DVI plus VGA. Don't laugh -- I have done this myself, by accident.) Is it possible to temporarily connect a 2nd screen, just for the installation? I suspect the problem may go away once the OS is installed & updated, and any graphics drivers are installed. So you could disconnect the supplementary monitor then. -- Liam Proven - Technical Writer, SUSE Linux s.r.o.
