 |
|
Hi,
I got a few problems with my triple head setup using gnome:
2 monitors and a tv connected to a AMD Radeon HD6870
Dell U2412M connected via display port (primary screen, 1920x1200)
Dell 2007FP connected via DVI (secondary screen, right of primary, 1600x1200)
Samsung TV connected via HDMI (1920x1080)
The two Dell screens should display the gnome desktop (DISPLAY=:0.0) and the tv should be a second screen for XBMC (DISPLAY=:0.1, so that XBMC can change the refresh rate of the tv to match the video, no gnome/desktop). I got it sort of working but there are still some problems:
When X starts without the tv running the gnome desktop looks like I want it to on the two monitors (top bar only on the primary screen, maximized windows not spanned across both monitors, windows draggable from one monitor to the other).
When X starts with the tv running everything gets spanned across both monitors (i.e. they act as one big monitor). Is it possible to make gnome/X behave as above in that case?
Additionally when X starts without the tv being on and I later turn on the tv it isn't a separate screen but displays the same image as the primary screen. Is there any way to change that, without having to restart X/gdm every time?
Im using gnome 3.8 and ati-drivers (fglrx) 13.9. The xinerama use flag is not set and my xorg.conf was created by amdcccle (I only modified the identifiers).
Any help is much appreciated

In the meantime I tried the radeon driver (because with that I get LPCM over HDMI).
But with that I can't get the secondary screen to work.
With the following xorg.conf only one of the monitors work (hdmi always works). When I try to turn on the other one I get this:
| Code: | $ xrandr --output DVI-1 --auto --right-of DisplayPort-0
xrandr: cannot find crtc for output DVI-1 |
When I configure all three displays as separate devices (see # lines in xorg.conf), they all work but of course I don't get one desktop out of the two monitors.
Has anyone run into similar problems with the radeon driver?

edit2: I fiddled around a little bit more and it looks like there is something wrong with the way the CRTCs get allocated. When I put all three screens on one device it looks great on the desktop. xrandr gives the following then:

But then of course XBMC doesn't work as I want it to.
When the TV is on a separate device, both displays (ie DISPLAY=":0.1" and ":0.2") only have CRTCs: 0 and the tv and the primary screen both get CRTC: 0. But then of course there is no CRCT left for the secondary screen.
Am I doing something wrong here or is that a bug in the software? (if so, which? xrandr, x.org, radeon?)
I also tried kernel 3.13.1-gentoo but that didn't change anything. |
