Have you got that the right way round? My experience is that with a KVM the monitor's EDID may not get passed to the computer. I think so. Note that _both_ of my cases are with a KVM: the first is when the KVM is switched to (connecting the monitor, etc., to) the computer I'm talking about, and one is when the KVM is switched away from the computer I'm talking about (switched to an otherwise unrelated computer). (I'm not talking about the case of having the monitor connected directly to the computer.) Of course, I'd like to force it to use the higher resolution regardless of which computer my KVM is switched to when this computer boots. Something like video=DVI-1:1280x1024 as a kernel parameter (when KMS is used) works for me. What tools (commands) are there in console-data or console-tools or whatever for getting (and changing) the console video settings?

capturing console resolution from auto-detection for when KVM switched away?
What command shows the virtual console video mode (specifically, the information needed to set it to that mode if it's in a different mode)? When I boot with my monitor connected (through a KVM), I end up with high-resolution virtual consoles (67 rows by 240 columns). However, when I boot with the KVM switched away, then since the kernel/etc. can't auto-detect my monitor, I get lower resolutions (48 rows by 128 columns, or 25 by 80 once). Of course, I'd like to force it to use the higher resolution regardless of which computer my KVM is switched to when this computer boots.

Anything interesting in dmesg? Of course, I'd like to force it to use the higher resolution regardless of which computer my KVM is switched to when this computer boots. I seem to recall that for KMS this is done via kernel parameters.
