If I plug an external CRT to my laptop, it normally either displays the same picture as the laptop's panel, or extends the desktop area. But I'd like it to be a separate virtual desktop (a workspace, in terms of Gnome). Is it possible?

I use Toshiba L10 laptop with Intel 82852/855GM onboard card. And I switch (which, AFAIK, can be an inconvenience with Xinerama) monitor configurations (detach all monitors but a laptop's built-in panel, attach monitors with different resolutions) pretty often (sometimes many times a day).

What kind of videocard are you using? With an nVidia card I would recommend using twinview. Otherwise it should be possible to simply enable xinerama for it to work.

@Ivan: you're right, xinerama sometimes get confused when changing monitor sizes dynamically (on my laptop with nvidia drivers I am sometimes required to restart X to make it work properly). If you have all the resolutions you commonly use preconfigured in your xorg config than it usually works fairly well with intel though. Or atleast... the last time I tried (admittedly, 2-3 years ago) it worked nicely. –  Wolph Oct 3 '10 at 2:51
    
Would you be so kind to take a look and share your experience at this question then: ubuntu.stackexchange.com/questions/5138/… –  Ivan Oct 3 '10 at 20:51
    
I've enabled Xinerama the way yo wrote, but the situation has not changes. Both displays are still merged into one big workspace instead of 2 separate. There are minor signs of that something has changed, but no practical difference. Any further ideas? –  Ivan Oct 4 '10 at 23:19
    
@Ivan: with xinerama you have 1 screen, but they are virtually separated so you can maximize everything per screen and it should feel for most things as a separate screen. You can still drag screens from screen 1 to screen 2. The alternative is 2 completely separate screens but that way you won't be able to move anything from screen 1 to screen 2 anymore. –  Wolph Oct 5 '10 at 10:11
