Lost Display Settings

[John Durant]

Hi,

After installing Edgy on a Compaq lap with an ati video chipset all 
video settings were lost. Scenario went like this:

- Installed Edgy on laptop with CRT attached. Default resolution set at 
1400x1050. After some font sizing adjustments display looked superb.

- With lid on laptop closed disconnected the monitor to use it with 
machine2, also a laptop. Machine2 runs XP SP2 at 1024x768

- Disconnected from machine2, reconnected to Edgy machine.

- Screen resolution went to 640x400 or thereabouts. System would not 
allow resetting of display options from Systems Settings,

- Reinstalled Edgy. Again resolution back to 1400x1050, the preferred 
setting

Question:

I understand it is probably not a best practice to unplug a monitor 
while the machine is running. That being considered, can these display 
settings be edited or backed up in case this situation should arise 
again? Have checked man pages for xinit and couldn't find this information.

Thanks,
John
