Screen Resolution too small when upgrading Ubuntu to 8.10

gNguyen · 10-15-2008, 04:02 PM

I had Ubuntu Dapper, then upgraded to Ubuntu 8.04. The Xorg worked fine until I upgraded to Ubuntu 8.10. I'm using an old laptop and the screen resolution is 800x600 and I wish to make it 1024x768(which was what it was on Windows XP). I tried doing xrandr but the only option that comes up is 640x480 or 800x600. I ran xvidtune and it works, but I don't know how to use it. Here's my Xorg.conf:

Code:

# 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

Please Help!!!!

Hi!

Try running:

Code:

% sudo dpkg-reconfigure xserver-xorg

This will ask you detailed questions about what you want from the X server, including all resolutions.

If this doesn't work, post your model of laptop and its specs. One of us can probably post a working xorg.conf for that model.

Not with (Beta) Ibex it won't - you'll get the same junk as posted above.
Maybe it'll be better on release - I wouldn't bet on it.

I had to steal xorg.conf from another working distro for my Inspiron 1100 (I keep it just to see if it can be made to work).

This is a good example to always back up important config files;

ex. xorg.conf
grub.conf

etc . . .

I you are using gnomb just go to System -> Preferences -> Hardware and select Screen Resolution. Change it to 1024x768 and it will write it to the xorg.conf file. Then logout and back in and it should work. You can find the similar setting under KDE menu . . .

"sudo displayconfig-gtk" doesn't work on my install within VirtualBox (command not found) - this was after downloading the latest install last night and grabbing all the updates it could install (IIRC it couldn't install all for some reason)

Editing xorg.conf has no effect either.

edit: installing the guest additions didn't help either, but would only work for VirtualBox users anyway...

from the VirtualBox menus "install guest additions"
open a terminal
sudo nautilus
run the "VBoxLinuxAdditions-86.run" program from the CD

As root:

Make sure you have the right packages for a generic Xserver:

o aptitude install xserver-xorg xserver-xorg-video-vesa

Copy the following to /etc/X11/xorg.conf

Code:

# /etc/X11/xorg.conf (xorg 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 /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/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.
#
# 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

Hi I just wanted to say I have an iMac running Parallels 3.0 with 1680x1050 resolution.

I also have a MacBook Pro 1440x900 similar configuration.

It is really humorous how extraordinarily complicated, convoluted the myths and truths are regarding screen resolution in Ubuntu. There aren't as many rumors about King Tut's Tomb in Egypt in 3,000 years as there are about trying to set screen resolutions in Ubuntu. It really is crazy. In the past year of computing this is my #1 headache. Thanks to this thread if any of the above works! I am trying now!
