Ubuntu 9.10 - Monitor not detected - No xorg.conf

dean_e_boy · 4 Nov 2009 at 13:22

Hi all,

Has anyone else had this problem, I have a samsung syncmaster monitor and in Ubuntu 9.10 my screen resolution is set to 800x600 ( from memory ), when I used an older version of Ubuntu I edited the xorg.conf file so I could set the resolution to 1440x900, however this does not exist now.

Has anyone had this problem and resolved?

Regards

Dean

Not had the prob, but this should fix it.

Code:

# X -configure
# X --config /root/xorg.conf.new
~~ If successful ~~
# cp /root/xorg.conf.new /etc/X11/xorg.conf
# /etc/init.d/gdm restart (assuming gnome is your DE.  Could also be xdm, kdm, whatever)

EDIT: the test line might be "# X -config-file /root/xorg.conf.new"... not sure

i had the same problem with adding modelines on karmic eventually i found some xorg settings that pretty much turned every protection off and allowed for a custom modeline.
i didn't much me much though either something in xorg or the nvidia driver had changed i could get the res i wanted but couldn't adjust the picture being too wide and too far left. :/

Why in late 2009 is a supposedly mainstream Linux distro still unable to even get the monitor detection right, OR allow you an easy way to set it yourself?

When I tried Ubuntu 9.10 recently I had the same problem, and it is ridiculous.
