Dual monitor configuration

Beginner

Wednesday, July 26th 2006, 4:43am

I have a 19"LCD monitor and a 17" CRT monitor. I've managed to get dual head working reasonably on my nvidia 6600, using seperate devices and seperate screens; i.e. each monitor has its own instance of KDE (there are two kdesktops active). This is not ideal.

Problems:

a) Settings are not shared between both KDE instances. E.g. I have different desktop backgrounds; the panel has different settings, shows different things, etc.
b) However, some settings are linked; I have the panel configured to unhide when I touch the top of the screen. However, the panel on the LCD never hides; the panel on the CRT shows and hides when I touch the top of either screen.
c) There's some sort of geometry constraint; when I drag the panel on the LCD screen, it jumps around an imaginary 1024x768 box (i.e. taking the resolution of the CRT, as opposed to the LCD.)
d) I can drag icons between the two screens (KDE prompts me with the "move here?" dialog, which is pretty cool; however, windows are stuck in the screen that I open them in.
e) Global key shortcuts only work on the LCD monitor; e.g. I have ctrl+alt+. set up to open an aterm; whether the mouse pointer is on the CRT or the LCD, the aterm always opens on the LCD screen.
f) KDM launches on the CRT; I'd far prefer it to launch on the LCD.

Here's the goal, and use case:

My LCD is center; the CRT is off to the left. Most of the time, I plan only to use the LCD, since the CRT is a different size. However, when e.g. editing video in cinelerra (which has a multiple window interface, like GIMP) it would be cool to drag some of the less important windows to the CRT, but be able to see them without switching the z-order of any windows. Or, when working on a web page, I can have quanta active on the LCD, and a browser sitting on the CRT ready to be refreshed. Etc.

It seems that this might be best accomplished by mapping each screen to a different KDE desktop.

My xorg.conf is attached. Any help here would be appreciated. It seems like some of the problems I found so far are genuine bugs that I should file, but if you know workarounds I'd like to know them first.

Thanks!

Hi I am sorry I cannot really help you with your problem because I don't really understand what you want, but I have problem you might be able to help me with.

I have a Samsung X10plus with a Nvidia Fx 5200go [LCD/CRT].
I have setup my xorg.conf like the following, which works very good for my needs.
But it only works when I have both of my screens in a 1024x768 solution.
Which is a little bit to low for my CRT Monitor (LG 901B) but if I set the resolution of that screen to something higher my desktop is bigger than the display of the monitor.
