Issue with screen display on Mandriva 2008

k0lvert · 11-08-2007, 07:01 AM

For some reason, certain programs like CUPS notification and screensavers are displaying off-center on my screen. It doesn't look like they are shrunk, but just off-center. In the case of my CUPS notification, it is in the upper left-hand corner, and I can't see the blue "move" bar so I can move it down... and of course I can't "move" my screensaver, since as soon as I move my mouse, it stops!

But when I test my screensaver via Desktop settings, it shows it perfectly centered on my screen, filling the whole screen. I'm pretty clueless at this point...

Check you /etc/X11/xong.conf file and make sure you have the right Vertical and Horizontal set for your monitor. If your not sure what your monitor uses do a google search on your monitor. Then edit the xorg.conf file and put in the vender recommended settings. The part you will edit will look something like this, this is my xorg.conf.

Code:

Section "Monitor"
    Identifier     "Generic Monitor"
    HorizSync       30 - 83
    VertRefresh     56 - 75
    Option         "DPMS"
EndSection

Also if you are using a LCD monitor some if not most have a autoset button on them.

I'm sorry... I should have posted more info about my monitor. I'm new to both Linux AND forums, but I'm trying my best to learn both simultaneously.

My monitor is a Dell E773c, weblinks for it's specs are:
http://support.dell.com/support/edoc...c/En/specs.htm and http://reviews.cnet.com/crt-monitors...9.html?tag=nav

This is what I found when I opened my /etc/X11/xorg.conf

Code:

Key section being:

    HorizSync 30-70

From what I can tell, my xorg.conf is setup properly... the HorizSynch and VerRefresh match up with the specs listed on the first website. So I am still stumped, but have learned a lot just from this exercise in gathering all this info.

Also, I just found the section on this forum about adding to the HCL, and I am fully intending on listing my hardware there.
