Increasing a 800x600 resultion to a 1024x768 [New User]

[edghh]

¡Hi!

I'm a new Linux Ubuntu 9.04 user and i would appreciate any help with the following problem:

I just installed Ubuntu 9.04 on Lap Toshiba Satellite A20 - SP279 and after checking up the basic configuration, i found that the highest resolution i'm able to choose is "800x600" and it would be great if a could increase it to "1024x768

Because of my inexperience with linux, i don't know if it's a driver problem or if i just have to edit the xorg.conf (i have seen in other posts that its a common solution).

I don't even know my video information, all I can share now, it's my actual "xorg.conf" file info

-------

# 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

Thank you all.

Hey,
I had some trouble finding what kind of video chipset your laptop has. Could you please go into a terminal and post the results of running

lspci |grep VGA

Stuff in terminal is CaSE SenSItIve, by the way. If you have trouble copying it, copy in gnome-terminal is shift-ctrl-c , or you can highlight and right click to copy/paste.

When asking for help with video stuff, we need to know what drivers your card runs, things are different between nvidia, ati, intel and others. Best of luck!

Try this on the file xorg.conf

Section "Monitor"
Identifier "Configured Monitor"
Option "DPMS" "true"
HorizSync 30.0-60.0
VertRefresh 50.0-70.0
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1024x768" "800x600"
EndSubSection

After typing lspci |grep VGA in the terminar i got this result:
