My Iiyama CRT dies a week or two back and I replaced it with a TFT Iiyama but now my dual-boot PC doesn't seem to know that there is a new monitor attached. The result is that despite trying to enter the interactive hardware setup when the machine boots - Mandrake 7 - it keeps going and continues into the desktop with the result that the monitor can't cope with what's being thrown at it and reverts to my other machine - not a Windows/Linux box.
Any ideas how I can fix this? I have all the Mandrake CD btw but very little understanding of Linux so far.
I'm going to assume that you're running X 4.0.? since this is presumably fairly new kit.
I understand that TFT monitors have a fixed resolution - say 1024x768 - and can't scale to anything else. What's probably happening is that X is trying to start with a different res so your monitor ignores it. The solution is to edit /etc/X11/XF86Config-4 (same file without -4 is for X < 4.0.0) and make the 'Display' things in the 'Screen' section look like this:
SubSection "Display" Depth 1 Modes "1024x768" EndSubSection SubSection "Display" Depth 24 Modes "1024x768" EndSubSection
You should probably leave in the other depths, but depth 24 is the one you're most likely using. At the moment, you probably have some other res' on the 'Modes' lines - remove all but the one your monitor supports.
Bingo! The blind leads the way.
