Description of problem: I have a server room with a single keyboard, mouse, and monitor. A KVM switch controls the machine with which those devices communicate. With both Fedora 7 and Fedora 8, the monitor is not detected properly when the KVM switch is set on the target machine. I get a resolution of 800x600 and an invisible mouse pointer. I have to explicitly set the horizontal and vertical refresh rates of the monitor, and list the modes I want in xorg.conf. I also have to turn off the hardware cursor to get a visible mouse pointer. If I plug the monitor directly into the target machine, detection works, so the KVM switch is playing a role here somehow. I am attaching the xorg.conf I have to use, as well as an Xorg.0.log when that xorg.conf is in use. You'll note that I also set the TargetRefresh option. That is because without it, I do get 1280x1024, but at a suboptimal refresh rate (I've forgotten what). I'm happy to mess around with the settings if there are things you would like me to try. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.3.0.0-42.fc8 How reproducible: Always Steps to Reproduce: 1. Set the KVM switch to the target machine 2. Boot the machine Actual results: 800x600 resolution and an invisible mouse pointer Expected results: 1280x1024 resolution and a visible mouse pointer Additional info:
Created attachment 297253 [details] xorg.conf that works
Created attachment 297254 [details] Xorg.0.log with the xorg.conf that works
There's really not a lot we can do about this. The KVM is physically preventing us from asking the monitor what it can do.
Well, that's what I thought. But in this thread: https://www.redhat.com/archives/fedora-devel-list/2008-February/msg02454.html https://www.redhat.com/archives/fedora-devel-list/2008-March/msg00046.html Matej Cepl insisted that this behavior is a bug and asked me to file it as such. So I did. Maybe you should assign the bug to Matej. :-)
I should deserve it ... Sorry.
