Can't Change Resolution


Hello,

First of all sorry my english is not that good and im not that savy in linux but anyway i need some help.

I just installed 8.10 and im stuck at 640x480 or 800x600 resolution and i want to have it at 1024×768.

I used to have ubuntu 8.04 and Fedora 8 and it was working just fine, in windows xp works fine also.

The video card the pc has its an Integrated Intel 82845G/GL

This is what i have on the xorg.conf file:

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg


Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection




when i try to reconfigure the xserver with the command:

sudo dpkg-reconfigure xserver-xorg

it doesn't give me any option to set any resolution, or vertical-horizontal range at all.

if i try the command:

sudo dpkg-reconfigure -phigh xserver-xorg,

it just backup the current xorg.conf file and it makes a new one with the same information.

i also downloaded the drivers for this chipset from the intel website but when i try to install it says:

Compiling new agpgart module...

ERROR: AGPGART module did not compile

Compiling DRM module...

ERROR: Kernel modules did not compile

The DRI drivers can not be installed without the latest kernel modules.
Installation will be aborted. See the dri.log file for information on
what went wrong.

It's saying like im missing the kernel modules but im not sure how to verify that, i was checking on synaptic i have these installed (linux-restricted-modules-2.6.27.9-generic and linux-restricted-modules-generic). But i don't know if the error is refering to that.

Can Anybody Help Me Please. Sorry for the long post i just wanted to provide as much info as i could.

Thank You.

In xorg.conf find SubSection "Display" and manually add 1024x768 like so:

Modes "1024x768" "800x600" "640x480"

Update xorg.conf & restart X with Ctrl+Alt+Backspace. Hope that helps.

Hmm... Something is wrong with your X config... You should have Driver "intel" and not Driver "vesa".

You may also try to let everything autodetect at runtime. In my xorg.conf I have (debian and a different video chip though):
Code:
Section "InputDevice"
        Identifier      "Generic Keyboard"
        Driver          "kbd"
        Option          "XkbRules"      "xorg"
        Option          "XkbModel"      "pc105"
        Option          "XkbLayout"     "dk"
EndSection

Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "mouse"
EndSection

Section "Device"
        Identifier      "Configured Video Device"
EndSection

Section "Monitor"
        Identifier      "Configured Monitor"
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
EndSection
The driver module should be called something like xserver-xorg-video-intel
