How top setup T41 to use external monitor.
Previously used “sytem-config-diaplay”
this caused problems where login at X would log staight back out again.
Ran “aticonfig --initial=dual-head --screen-layout=left” and so am now using proprietary ATI drivers.
“sytem-config-diaplay” will no longer work as the ati drivers are now in force.
The external monitor now shows “Input signal out of range”.
Running the command “xrandr -s 1024x768” changes the resolution and the external screen displays properly.
Running the command “xrandr -s 1400x1050” changes the resolution back again and the external screen shuts off.
Now the external screen is working as a second screen - where I want a clone for presenting.
Run "aticonfig --desktop-setup=clone --overlay-on=1"
