In your xorg.conf file try editing the Modes part of the screen section. Add your desired resolution there. It should look something like

Code:

Section "Screen"
  DefaultDepth 24
  SubSection "Display"
    Depth      15
    Modes      "1400x1050" "1280x768"
  EndSubSection
  SubSection "Display"
    Depth      16
    [b]Modes      "1280x768"[/b[
  EndSubSection

As a last resource, you could use the gtf command. gtf <horizontal> <vertical> <refresh> -x

For example:
gtf 1400 1050 56 -x

This will produce a modeline called "1400x1050_56.00". Edit the name to "1400x1050_56". Add the entry to the "Screen" modes section and the entire modeline into the "Modes" section. If you don't have a modes section, then you can add it to the "Monitor" section. Read the "man 5 xorg.conf" manpage for details on the format of the xorg.conf file.

You need to configure your X with the correct driver for your card. lspci should provide you the information about the card.

If it is an ATI card you'll want to download the xorg driver from the ATI website. google linux ati

after running the ati driver installer and then the ati config app your xorg file should be set up properly for the card and you'll have a full range of modes. The vesa driver you're most likely using now is pretty limited.

If your card isn't ATI you'll need to configure for the correct driver. In this case try running xorgsetup as root.

Hallo again well it doest work neither the first way nor the second i changed the xorg.conf but nothing then i instal ati's drivers properly and i type aticonfig --resolution=0,1400x1050 as it sais in the manual and now i cant even start with startx!!!;-(What the hell t do??

Then I would suggest what jschiwal said about creating a modline.

ryudo · 11-29-2006, 01:01 AM

ok i wrote gtf and the other and t sais that modline created but i cant find were is it to rename it can someone tell me step by step what 2 do?
