XRandR
I have installed Fedora 8 on my
workstation. Everything works as expected, except the multihead support.
I am getting the "Requested Entity already in use!
" error message.
The problem is that my xorg.conf
uses two separate screens,
instead of one screen merged by XRandR extension (which is
apparently
the preferred way of doing dual-head now).
While not a bad thing per se, XRandR seems to be unusable for my dual head setup: I want the workspace switcher work separately for each head. With XRandR, there is only one big virtual screen area, so the workspace switcher switches both heads at once.
I think XRandR would be useful for my laptop which has 16:10 screen, so the aspect ratio for the external beamer would be different. Also, it could allow to see the lecture notes together with slides when doing a presentation. Here is a little RandR dualhead howto.
My dear lazyweb, does anybody know how to do a multi-screen setup (as opposed to one virtual screen area) in XRandR? For now, I have downgraded to the Fedora 7 version of the ATI driver, which works the way I want. Bug reported as #368531.

My WM can switch workspaces separately for each screen, so it is possible to do what you want even with one big virtual desktop across multiple screens. You only need better WM :o)

GNOME workspace switcher also can switch virtual desktops separately for each screen. But with XRandR, you don't have two screens.

Screen = one head (physical device). Evil terminology :-)

I have the same problem. I found the latest xorg 6.6 broke, and was suggested to upgrade to 6.7 (with RandR 1.2). But that prevents me from doing the two-screens-with-separate-WMs trick to allow me to control workspaces on each independently. thingie, which WM do you have that allows this? (I'm using sawfish.)
