Comment 7 for bug 103530

I just tried something totally new. I picked up an old crt monitor and booted a live CD and it completed the boot AND had a display output at 1280x1024@60mz. THEN, while it was still up and running, I unplugged the CRT monitor and plugged in the flat panel monitor, and it switched on ! I have lift off. but this re-inforces the problem, why is the flat panel monitor switching off and displaying an input out of range signal error if the display output is valid when connected to a crt when booting ? IS it possible that during the probing of the video hardware that a bad signal was sent resulting in flat panel protection shutting it off ? I have no room to keep a CRT monitor around my workstation strictly for the purpose of installing an OS when I have a perfectly functional flat panel that preforms just fine with other older Ubuntu and ubuntu derived distros. My flat panel displays the 1280x1024@60 perfectly fine with other distros, why is this issue limited to only the newer ubuntu 6.04 and on distros ? Last note: I tried this method on all the other computers that had the same result and this method worked on all of them, so it is not a computer or video card problem(because they vary greatly), it is restricted to just the flat panel display. The FP is a dell 2007, brand new. however I had the very same problem with my older dell FP1701 display that was 5 years old also, and that was why I bought a new display device, to eliminate the possibility that it was my hardware, this shows to me that it is not my hardware, it is a software issue from ubnuntu 6.04 and on. Ubuntu 5.10 did not have this issue.
