[Cialug] Changing X settings from the command line

[Bailey, Jonathan C]

Hmm.. Found something called 'xrandr'.. Anybody have any experience with
this? Also, does ACPI fire an event when the laptop is docked or is the
only way to tell the docking status is to check the number of fingers
and toes attached?

AFAIK the X Server has to restart to change resolution. You can have
multiple virtual resolutions, but that means screen-scrolling, which you
probably don't want.

A fairly simple method would be for it to have 2 versions of your X
config files (1 for docked, 1 for standalone), when it detects a change
in the docking status, have it copy the new config... then restart X.

I use the 2 config file thing on my laptop, so I can switch down to the
1024x768 that the LCD projector uses - but I just copy the file
manually.
