How to change the color depth?
Solution 1
You can create a new xorg.conf by switching into a virtual virtual console (Ctrl + Alt + (F1-F6)) and running sudo service gdm stop
.
Then run Xorg -configure
(yes, it should be Xorg
, not xorg
).
If you had an old xorg.conf file in /etc/X11/ you'd first back that up by doing sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
.
Then move your newly created xorg.conf to /etc/X11/ by running sudo mv xorg.conf.new /etc/X11/xorg.conf
and restart gdm by running sudo service gdm start
.
Then you can change the color depth in there by finding the appropriate section and changing/adding whatever's in there to DefaultDepth 16
Solution 2
Try doing this step, but before you get to the sudo service xdm start
part, change the screen section (within the xorg.conf file) to something like:
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 16
Modes "1024x768"
EndSection

I have Ubuntu 10.04 installed on a Dell C600 and the highest available resolution is 800x600. From my previous I remember 1024x768 would work after setting the colour depth to 16bit, but there is no
xorg.conf
in/etc/X11
anymore. So, how can the colour depth be changed on lucid lynx? -

xdm
withgdm
and it's fine -
Tobias Kienzler over 13 yearsThanks, that changes the depth. Unfortunately, there seem to be more steps necessary, I still cannot change the resolution to 1024x768.
