Yes, indeed, commenting out that line starts the display on an external monitor. |
| 23 |
|
| 24 |
With a bit of experimenting I now have instead |
| 25 |
|
| 26 |
Option "TwinView" "true" |
| 27 |
Option "TwinViewOrientation" "clone" |
| 28 |
|
| 29 |
in my xorg.conf. Now I can switch between the external monitor and my |
| 30 |
LCD by pressing the "Fn-CRT/LCD" key. However, I need to issue the |
| 31 |
command "xrandr -s 1024x768", since the external monitor doesn't |
| 32 |
support my default of 1400x1050. Does anyone know how to make the |
| 33 |
virtual screen size default to one supported by both monitors? |
| 34 |
|
| 35 |
Also, when connecting the external monitor I need to restart X. Would |
| 36 |
be nicer if that weren't necessary. Ideas? |
