1024x768 not available on ubuntu 9.10?


I have just updated from ubuntu 9.04 to 9.10 and everything ran beautifully until I tried to change the resolution from 800*600 to 1024*768 which isn't in the list!! I was able to run it fine in 9.04 any help?

You might be able to fix this by looking up the specification for your monitor so that you can explicitly specify the "HorizSync" and "VertRefresh" values in the Monitor section of your /etc/X11/xorg.conf

I don't know why it should not work now when it worked before, or if there is a more "ubuntu" way to do this.

xorg.conf

ummm ok I'm just using a 1024*768 hdtv with vga and my xorg.conf file has only this in it:
# 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"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

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

I had the same problem. It is about Ubuntu not including the drivers for some graphic cards. I found those drivers in the Ubuntu forum. I use the SiS Mirage 3 graphic card and the drivers are the SiS 671/672. If you use those drivers I can send you the linux driver auto-installable.

If you can't find the refresh rates from your monitor manual or from an internet search you could try following the instructions at this link and see if that helps.

http://www.cyberciti.biz/faq/howto-u...probe-command/

I had to run it a couple of times to get it to tell me the "monitorrange"

Code:
# ddcprobe | grep range
monitorrange: 30-96, 48-120
My monitor section looks like this:
Code:
Section "Monitor"
    Identifier     "Configured Monitor"
    HorizSync       30.0 - 96.0
    VertRefresh     48.0 - 120.0
EndSection
Don't just use my numbers though, as this is a different monitor and will have different ranges.

It may also be true that ubuntu is not using the correct driver but it might be easier to diagnose that once you've got the resolution you want!

Davmax could you send me a link for SiS Mirage 3 graphic 672 drivers, I also have this graphic and my resolution on 9.10 is not good
I am new to Linux so if there is something else I need to install please send some instructions!
My motherboard is SIS Mirage 3 672 and my graphic and audio card are integrated.
Btw, wireless is not working either.

I hope someone will help me because my brother gave me a two week deadline to fix this or he will install windows again

For the graphic card just download this driver, double click, install, log off, log in, and it should be ready in your high resolution.

About the wifi it was also a nightmare for me. I am a beginner so I will probably not be able to help you, but tell me what is your wireless card and if it is the same as mine I will try to help you.

As for more things to install I advice you to google for "things to do after installing ubuntu karmic". There are a few good ones. Try with this for instance: http://blog.thesilentnumber.me/2009/...nstalling.html

By the way, I always end up uninstalling Linux, I get fed up with it. Works really bad, and in my laptop it is always much slower and buggy then Windows XP, plus the programs are worse that the Windows ones. I am interested in Linux for the safety of no-virus, but bufff... it's really annoying, slow and buggy.

Good luck.
