| Hi, |

Hi, Michael! |
| 20 |
|
| 21 |
I wouls suggest you to remove all dual head configuration from your |
| 22 |
xorg.conf file, letting only the lcd configuration as usual and use |
| 23 |
xrandr to control the resolution of your VGA output and lcd. |
| 24 |
|
| 25 |
I'm saying that because this is exactly the setup I use here and it |
| 26 |
works perfectly! I also have an 855GM based laptop and after being |
| 27 |
introduced to xrandr, I think I would never touch my xorg.conf again for |
| 28 |
dual head configuration. |
| 29 |
|
| 30 |
|
| 31 |
When you clean up your xorg.conf file, when you start x, your VGA output |
| 32 |
will be automatically mirrored. The resolution will be different but X |
| 33 |
will try to get a resolution on both monitors to accomodate both panels |
| 34 |
(LCD and VGA). |
| 35 |
|
| 36 |
After booting, you will be able to change your resolution with the |
| 37 |
following simple command: |
| 38 |
|
| 39 |
|
| 40 |
xrandr --output VGA --mode 800x600 |
| 41 |
|
| 42 |
|
| 43 |
You may execute xrandr to see what are the available resolutions and |
| 44 |
also the syntax for using dua head. |
| 45 |
|
| 46 |
For example, this is what I use to setup my dual head: |
| 47 |
|
| 48 |
~ xrandr --output VGA --mode 640x480 --left-of LVDS --outputLVDS --mode |
| 49 |
1400x1050 --rate 60 |
| 50 |
|
| 51 |
|
| 52 |
|
| 53 |
Also note that you may need to configure in your xorg.conf (I don't know |
| 54 |
how to change it dynamically) your virtual screen size. You have to put |
| 55 |
the following in your xorg.conf: |
| 56 |
|
| 57 |
~ SubSection "Display" |
| 58 |
~ Depth 16 |
| 59 |
~ Modes "1360x768" "1400x1050" "1024x768" "800x600" |
| 60 |
"640x480" |
| 61 |
~ #Modes "1024x768" "800x600" "640x480" |
| 62 |
~ #Virtual 1360 768 |
| 63 |
~ Virtual 2048 2048 |
| 64 |
~ EndSubSection |
| 65 |
|
| 66 |
|
| 67 |
I hope it helps. |
