[SOLVED] Screen Resolution

[mcuk2010]

Hi Folks

Just Installed the latest version of Ubuntu Netbook on my Toshiba Portege 7200 and the screen resolution is set to 800x600. The OS is not recognising the fact the laptop can do 1024x768.

I've been searching the net for a few hours to fix the problem and I'm not getting anywhere.

The fix to the problem is to add the info below to the Xorg.conf file.

This file does not seem to exsist on the latest version and if I create it manually it does not work.

Can someone please advice on how to fix the problem.


# 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

First of all the silly question. Did you reboot after creating this file?

Secondly, what happens if you remove the # from the lines

#Modeline "1024x768_60.00" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
#Option "PreferredMode" "1024x768_60.00"

Yes, I did a reboot.

The file is not getting saved as it does not seem to be used in the latest version of Ubuntu which is why I'm asking what do you do in the new version.

The file is not there by default and if you create a new file with the same name it doesn't work. Even if you save your changes they are removed on restart.

New Xorg does not require xorg.conf, but it will read it if present.
First, make sure it is called xorg.conf, not Xorg.conf.
Second, I'd make sure it is there before X starts. If this file is created during X session it may get wiped when you shut down. (Not sure about this though.)

The OS is not recognising the fact the laptop can do 1024x768.

For sake of clarity, OS and Xorg are not the same. GNU/Linux OS has no GUI.

This file is outside of your home directory so you will need root privileges to edit it (more accurately to save the changes).

Press Alt + F2 and type gksu gedit, you can then edit and save this file as root by giving your password when asked. The file should not be replaced when booting. As Segfault says, make sure the file is xorg.conf in the path /etc/X11/ (that's 2 ones) as Linux is case sensitive

Cheers guys. Issue fixed. Did as you suggested and removed the # from the two lines below.
