Weird Display Thing

[AliasN]

I'm sure everyone's sick of hearing this right now, but hear me out.

I just installed Fedora Core 5 on an eMac (Radeon 7500, 1Ghz), it installed fine. However, whenever X starts, the screen is off center. More than a little bit. About 1/4 of the screen is missing. So, I heard about xvidtune, and that allowed me to get it almost on center (the icons in the applications menu were cut in half). However, the Modeline statement in the Monitor section prevents X from starting; if I change the ModeLine's name to 1280x800 (which X wants to use, even though I specifically say 1280x960), X starts, but the display is cut off. There is no auto-center button, it's an eMac. I can't seem to drop the resolution down, for some strange reason it doesn't seem to care which res I have in the xorg.conf file. I even tested 640x480 (really noticable), made sure changes were saved, and did a killall Xorg, but still no go. Changing the Monitor type to generic gives me a bad refresh rate, and I get a black screen (although X has started). Ubuntu 5.10 worked fine for this, and I tried using my Ubuntu config file; same thing, 1/4 the screen missing. Is there a bad X server in FC5?

Thanks,

I had a similar problem with X on my iBook (Rage 128 card) withthe display appearing up and to the left of the screen, changing the resolution didn have any effect but hacking the xorg.conf file to change the depth from 24 to 16 and then restarting X sorted it. My the Screen section in my /etc/X11/xorg.conf file looks like:

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 16
SubSection "Display"
Viewport 0 0
Depth 16
Modes "1024x768"
EndSubSection
EndSection
