After a run-in with a cheap KVM (keyboard, video, mouse) unit, Jack Wallen discovers that the Xorg open-source implementation of the X Window System has evolved into something he never expected.
Recently I had a situation where a KVM was the cause of Xorg not being able to read the correct modes from my monitor. It took me a while to work out what was going on, but in the process I discovered something about the most recent Xorg that is both exciting and disturbing at the same time.
I had been installing Fedora 10 on my desktop, which had been running Ubuntu 8.10. Because the KVM switch was keeping Xorg from setting up 1,200×1,024 resolution, I thought I might just have to hand-tweak my xorg.conf to get it. Not a problem, I've done it hundreds of times.
