Fedora 11 + Lenovo T500 + Avocent Switchview

equals no video on startup... for some reason. It is some combination of all three hardware bits.. not sure exactly what to do about it though. My first set of problems seemed to be BIOS settings. On first connecting the monitor directly to the laptop I got no detection or startup except every few reboots. I then went into the T500's BIOS to assume a VGA out and some other flags. That has gotten it to work directly most of the time.

Going through the Avocent at startup always ends up with no video so I have to plug the monitor in directly and then everything back into the switch to get it to continue to work. I got it to work once through the avocent but got this kernel oops.

My guess is that there is something in the kernel driver that is not getting the right signal detection and the X11 code says no monitor is hooked up.. so we aren't able to connect to it via system-config-display or the new X widget tool.

Well on the good news.. I can now get my two test boxes working via the monitor/keyboard so my wires went down.. I just have to play around when I start the laptop up.

File yourself a bug, my man, on the appropriate video driver (even if it actually turns out to be in the kernel code, filing it on the video driver gets it to the attention of the right people faster). Also test with 'nomodeset' to see if that 'solves' the problem, in which case we know it's in the KMS stuff.
