[opensuse] Multiple displays during OS install
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. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Does the system maybe have two graphic cards/chips? lspci -- Gertjan Lettink, a.k.a. Knurpht openSUSE Board Member openSUSE Forums Team -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

No. Just one. It is a 6th gen Skylake i7 6700 CPU with 530 HD Graphics -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

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.

Nothing at all. Only one of the three connectors has anything attached.
Is this a desktop or a laptop?
A desktop computer.

Only one cable connected to one display.
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.
We are going to do that when we rustle up the various display cables and such for the other connectors. We are evaluating a new small MB that has 6 NIC chips. These are rare. So we would like it to work. We did not expect the display to act like this during installation. It's a first. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Other option would be text-mode install (just the basics), and do configuration later (I'd assume display to work better once the main system is running - but might of course be wrong :P )

Oh, sounds nice. Care to share the name? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I encountered a case, on a laptop, where the display went to the vga display, present or not and whatever we did on the keyboard (bios included) the laptop seemed impossible to install when somebody thought of connecting an other display and then no more problems. it's pretty often the case when on use an external display and forget to disconnect it before switching off, but on the case I speak of it was an old machine never used with external jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
