Monitor display off-centre

[Hush Lorentz]

I wasn't sure if this was hardware or software related, I assume it's both. I apologise in advance for this post as is will be quite untechnical. :) I'm new to Linux, in fact I just installed RedHat 7.3 on Friday night.

Ok, the problem: my monitor is displaying the desktop shifted to the right by about 70 pixels which causes it to overlap on the far righthand side. I booted into KDE and I can fix the problem with xvidtune but when I reboot the system, it goes back to being off-centre.

I tried booting into the failsafe console but it was also partially off the screen and I couldn't actually use it.

From the xvidtune man page:

"It will also print the settings in a format suitable for inclusion in an XF86Config file."

Specifically, the parameter you want to pass to xvidtune after centering the display is:

"-show - Print the currently selected settings to stdout in XF86Config "Modeline" format."

Once it spits out the modeline, paste it into your /etc/X11/XF86Config-4 file and you should be sorted.

That did the trick. :) Thanks very much!
