 Posted: Mon May 12, 2008 5:35 pm Post subject: How to make laptop monitor off and use CRT only in X? |
 |
|
First of all, I must say I have the worst of the bunch: ati-drivers. I am looking to have one configuration where X completely ignores my laptop's monitor and only works with the CRT port of my laptop. I have a 19" WS screen that can do 1400x1050 resolution, meanwhile my 15.4" laptop screen can only 1280x800. I would hope that after achieving the "shut-off and enable", that X would assume resolutions up to and including the native 1400x1050 pixels of the 19".
Here is my current xorg.conf (generated by aticonfig --initial --force to fix previous problems with dual-head configuration):
| Code: |

I am pretty sure xorg.conf just needs to be slightly modified for this to work. The resultant configuration is one that I would just switch manually, so I'd have two xorg.confs, one for regular mode, and one for CRT only mode. There might be some options specific to ati-drivers/fglrx. That is why I mentioned it.
Any help is greatly appreciated. |

Run to get output names, for example: | Code: | $ xrandr
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1280
VGA disconnected (normal left inverted right x axis y axis)
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 331mm x 207mm
1280x800 59.9*+
1024x768 60.0
800x600 60.3
640x480 59.9
TV disconnected (normal left inverted right x axis y axis) |
And disable one of them:
| Code: | | xrandr --output LVDS --off |
