Hi all,
I have a problem, that I can not solve by myself..
I had multiseat system with two graphic cards ( Intel i5 integrated and Nvidia gtx560 with nouveau). One session (on intel connected to monitor) is for user with gnome-shell, another (on nvidia connected to TV) is xbmc session.
It worked fine. But about two weeks ago I upgraded and reboot system. And now works only one of the graphic card (which is the default in bios). In Windows works both (as extended desktop)
Logs looks fine. There are no error messages..
~# uname -a
Linux 3.13.6-1-ARCH #1 SMP PREEMPT Fri Mar 7 22:47:48 CET 2014 x86_64 GNU/Linux
Using testing repositories now, but it happened when I have used only 'stable' repos.
I removed multiseat configuration, but it did not help.
After I tried to reinstall xf86-video-intel, module i915 no longer loaded automatically. And even after 'modprobe i915' xrandr see only nvidia card.
:~$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x64 cap: 0x7, Source Output, Sink Output, Source Offload crtcs: 2 outputs: 3 associated providers: 0 name:nouveau
Any suggestions, what should I do to fix it?
TIA

So, after some manipulations, intel drivers are loaded automatically.
Xrandr see second card, but does not see connected TV

What kind of manipulations did you do? I'm facing the same issue that xrandr --listproviders only shows the nouveau provider, while the intel one is missing.

Never mind, with the latest update today, the second graphic card started to work again.

The problem was in bios settings. To allow to work both cards simultaneously you should activate something called "Multicard mode", name depends on your BIOS/UEFI manufacturer.
But it only make visible second card in the system.
