Display problems?

[rcrummett]

Hello -

I am a new Linux user who managed to successfully install Debian Sarge on my laptop this morning. The default display has been set for 800x600, but when I try to change it to a larger resolution like 1024x768, my screen goes all weird and has a kind of tiling effect (like it took my 800x600 screen and fit it in the upper left-hand corner then tried to fit it again over and over in the remaining space). Needless to say, this is not what I want. I know that the computer can handle 1024x768 as that is my preferred setting in Windows (dual-boot).

What do I need to do so that I can effectively view my display at this higher resolution? My laptop is a Compaq Presario 2170US, if that helps. And any other information that may be needed, I should be able to provide. Thank you.

i thought that different sceen sizes have different resolutions that shouldnt be changed with debian...

Select the size of your monitor and press Enter. When the list of video modes is presented, for a 15" monitor make sure that only 640x480 is selected, that only 800x600 is selected if you have a 17" monitor, and that only 1024x768 is selected for a 19" monitor (use the Space Bar to deselect other resolutions). Then tab to OK and press Enter

When you run dpkg-reconfigure xserver-xfree86.............chose advanced mode and select the desired resolution


then in kde or gnome........run configure background or kde control or gnome control.................in order to pick the resolution


or edit /etc/X11/XF86Config-4 and add the resolution you want to the desired depth

here is an example from my file for 24 depth

SubSection "Display"
Depth 24
Modes "1920x1440" "1856x1392" "1792x1344" "1600x1200" "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection


I have all of resolution modes enabled

then restart xserver or reboot computer

You also need to set the proper refresh rates for your monitor.

I second ToastedToad, in fact I think setting your monitor correct refresh rates is the key to higher resolutions.

Absolutely, without the proper refresh rates you can not run certain resolutions.
