Resolution Support?
 
Hello,

I am currently running SuSE 10.1 with an nVidia 6800 GT video card. My current monitor supports a native resolution of 1280x1024, however the monitor I am planning to purchase tonight runs at a native resolution of 1920x1200. Under the assumption that my video card supports this resolution, will plugging the new monitor into the computer cause Linux to recognize and change to the new resolution? Do I need to make some kind of change/addition to xorg.conf before this happens? Do I need to somehow reconfigure X? My worry is that I plug the monitor in then get no picture because it's trying to run at 1280x1024 or something it doesn't really support.

Thank you :)

It depends a bit; if SuSE tries to find new hardware during startup, when it detects the screen it ought to configure it (set xorg.conf) automatically. But there is a chance it doesn't, and that's when you need to alter your xorg.conf a bit - the least you need to do is to scroll down to the Screens section, locate your monitor (probably there is only one section for it), find the resolutions-line (may be multiple, if there are multiple depths specified) and add the new resolution in the beginning of the resolution list.

The list is space-separated like

resolution1 resolution2 resolution3

and the first in the list (resolution1) is used if possible; then resolution2 etc. So just add your new resolution to the beginning of the list, written just like the others, save and restart X.

Here is how it looks...
Code:
Section "Screen"
  DefaultDepth 24
  SubSection "Display"
    Depth      15
    Modes      "1280x1024"
  EndSubSection
  SubSection "Display"
    Depth      16
    Modes      "1280x1024"
  EndSubSection
  SubSection "Display"
    Depth      24
    Modes      "1280x1024"
  EndSubSection
  SubSection "Display"
    Depth      8
    Modes      "1280x1024"
  EndSubSection
  Device      "Device[0]"
  Identifier  "Screen[0]"
  Monitor      "Monitor[0]"
EndSection
My assumption is I should just add another SubSection with Depth 24 and Modes "1920x1200", would this reasonable?

Follow-up question: Does Linux handle dual monitors well? Like, could I have a desktop on each monitor without much trouble? I believe I read that XGL/Compiz doesn't support dual monitors yet, but I'm not using that at this time.

This monitor is going to be here tomorrow, am I on the right track here or what?

Umm. Why don't you use SAX2? It is part of YAST2...
Simply call YAST and click on the hardware part. It will recognize your new monitor (hopefully ;)) and make the appropriate changes interactively via SAX2 then. (Hardcore-users can call sax directly...)

If that doesn't bring the wanted results you can still follow the other poster's suggestions.
