Unfortunately, I can't reproduce your error in my hardware. Both seats wake up correctly here. My hardware consists of an integrated Intel graphics device and a Silicon Motion SM501 PCI graphics card. I'm also using Xubuntu with lightdm 1.10.3 from trust-updates repo. BTW, did you upgrade your lightdm to 1.10.3? Dou you know this version has backported automatic multiseat feature introduced in 1.12 series? Although this is the default behaviour in 1.12 series, it must be enabled manually in 1.10.3. Just drop all your previous manual seat configurations ([Seat:0], [Seat:1], etc.) in lightdm.conf and put the following: [LightDM] logind-load-seats=true If you want to seat e.g. autologin user for each seat, just append the following sections: [Seat:seat0] autologin-user=USER FOR seat0 [Seat:seat-1] autologin-user=USER FOR seat-1 Now you can test again that setting above for disabling DPMS for your seat-1 X server: [Seat:seat-1] xserver-command=/usr/bin/X -core -dpms -s 0 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1209008 Title: [SRU] X doesn't work for video cards with non-KMS drivers on non-seat0 seats Status in X.Org X server: Fix Released Status in xorg-server package in Ubuntu: Fix Released Status in xorg-server source package in Trusty: Fix Committed Bug description: [Impact] * In Xorg-server versions older than 1.16, if Xorg is started as a non-seat0 X server (i.e. if it was started with -seat option where != seat0), it only probes platform bus for graphics devices, leaving devices with non-KMS drivers (like NVIDIA proprietary drivers and old ones like xf86-video-siliconmotion) unreachable.

[Desktop-packages] [Bug 1209008] Re: [SRU] X doesn't work for video cards with non-KMS drivers on non-seat0 seats
I have two discrete cards. So the difference is that your integrated card is probably on the platform bus, while both of my discrete cards are PCI-E devices. I started testing multiseat setup described in this thread only last Saturday and since then have always been using the lightdm version which supports automatic multiseat; in one of my posts above (where I thought that the multiseat setup didn't work) I enclosed my full lightdm.conf; it only consisted of logind-load-seats and logind-check-graphical. # apt-cache policy lightdm lightdm: Zainstalowana: 1.10.4-0ubuntu2 # means: Installed Kandydująca: 1.10.4-0ubuntu2 # means: Candidate Tabela wersji: *** 1.10.4-0ubuntu2 0 500 http://archive.ubuntu.com/ubuntu/ trusty-proposed/main i386 Packages 100 /var/lib/dpkg/status 1.10.3-0ubuntu2 0 500 http://pl.archive.ubuntu.com/ubuntu/ trusty-updates/main i386 Packages 1.10.0-0ubuntu3 0 500 http://pl.archive.ubuntu.com/ubuntu/ trusty/main i386 Packages The full lightdm.conf I'm using now: [LightDM] logind-load-seats=true logind-check-graphical=true [SeatDefaults] allow-guest=false [Seat:seat-1] xserver-command=/usr/bin/X -core -dpms -s 0 And with this setup the card assigned to seat0 in xorg.conf wakes up correctly, but the other does not.

Oh sorry! I didn't catch your lightdm.conf above. When you restart lightdm service, all Xorg processes are killed and then restarted. That's why your seat-1 goes back to normal when you do that. I suspect your seat-1 Xorg may be killed when suspending. You can confirm it by running ps -FC Xorg | less. Also take a look at lightdm and Xorg log files when your seat-1 fails to wake up.

Yesterday the behaviour was as described above: seat-1 card wouldn't come back. I'm also noticing a changed behaviour after boot and when greeters first appear: until yesterday, they appeared almost at the same time, with mouse pointers exactly in the middle of both.

SInce yesterday evening I played with printer drivers from http://www.bchemnet.com/suldr/; I installed/removed some of them back and forth. Then today I did apt-get install apt-show-version, and then did apt-get autoremove as suggested by apt.

[Desktop-packages] [Bug 1209008] Re: [SRU] X doesn't work for video cards with non-KMS drivers on non-seat0 seats
More details on todays behaviour: After boot both screens come up, but sometimes seat-1 does appear, sometimes not and instead seat0 display extends to both monitors. Regardless of whether seat-1 appears or not, the initial position of mouse pointer of seat0 is offset BUT related to seat0's monitor. I think it is exactly in the middle of a big screen composed of BOTH monitors. If, after boot, seat-1 does not appear, when I do ctrl-alt-f1 ctrl- alt-f7 at seat0 (which CanTTY=yes) then greeter at seat1 appears. BUT only until a screensaver kicks-in: then when I move a mouse at seat-1 (or even without it), instead of seat-1's greeter (no one is logged in at seat-1) a missing part of seat0's display appears - I have same folders at the desktop and they tend to appear in a part of the screen covered by seat-1's greeter. And then if I ctrl-alt-f1 ctrl-alt-f7 again, seat-1's greeter appears again. The difference to yesterday and the day before is that I played with installing/uninstalling some packages. The versions of packages of interest as of now are: lightdm: 1.10.4-0ubuntu2 xserver-xorg-core: 2:1.15.1-0ubuntu2.6 I'm using Unity. I have no light-locker installed. I must say that until yesterday I had rock-solid behaviour and fully functioning system except waking up from suspend. Then I perhaps messed something up with the installed packages. What packages other than lightdm and xserver-xorg-core should I check?

It works for me, too. That said, I experience problems with coming back from machine's suspend: the screen at seat-1 in my setup (please see above) remains blank. I don't know if this is related to multiseat setup in any way, but it is really annoying. I'm using a dirty workaround: at waking up I do service lightdm restart which is surely an overkill and definitely not a solution.

If it occurs, check output of command ps -FC Xorg and you'll see that a non-seat0 Xorg server has a lower PID than seat0 one. Moreover, the non-seat0 has opened a TTY, while the seat0 hasn't. [Regression Potential] * Very low. All these patches were well tested in xorg-server trusty package available in ppa:ubuntu-multiseat/ppa.

[Desktop-packages] [Bug 1209008] Re: [SRU] X doesn't work for video cards with non-KMS drivers on non-seat0 seats
** Package changed: fedora = hwe-next ** Changed in: hwe-next Importance: Unknown = Undecided ** Changed in: hwe-next Status: Unknown = New ** Changed in: hwe-next Remote watch: Red Hat Bugzilla #962907 = None -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1209008 Title: [SRU] X doesn't work for video cards with non-KMS drivers on non-seat0 seats Status in HWE Next Project: New Status in X.Org X server: Fix Released Status in “xorg-server” package in Ubuntu: Fix Released Status in “xorg-server” source package in Trusty: In Progress Bug description: [Impact] * In Xorg-server versions older than 1.16, if Xorg is started as a non-seat0 X server (i.e. if it was started with -seat option where != seat0), it only probes platform bus for graphics devices, leaving devices with non-KMS drivers (like NVIDIA proprietary drivers and old ones like xf86-video-siliconmotion) unreachable. Patch xfree86_allow_fallback_to_pci_bus_probe_for_non_seat0.patch from lp:~ubuntu-multiseat/xorg-server/trusty-matchseat fixes this. * systemd-logind has no intrinsic mechanism to assign non-KMS graphics devices to seats. In this case, one should tag another seat device (keyboard, USB hub, etc.) in udev as master-of-seat, and provide a suitable xorg.conf for that seat. In order to avoid that a given xorg.conf affects other seats, it should be passed to Xorg via -config xorg.conf.custom option, which requires X server command line customization support in DM in use (GDM, for example, has no such support). Patch xfree86_add_matchseat_key_to_xorg_conf.patch from lp:~ubuntu- multiseat/xorg-server/trusty-matchseat introduces a new MatchSeat key for xorg.conf sections Device, Screen, and ServerLayout, which will target a given seat only. Example file /etc/X11/xorg.conf.d/90-seat-1.conf: Section Device Identifier card0 Driver nvidia Option NoLogo True # This section will only apply for seat-1 MatchSeat seat-1 EndSection * systemd-logind can't handle any VT switching for non-seat0 seats, but Xorg-server older than 1.16 still opens VT even if it's started as a non-seat0 X server. This may lead to a race condition between X servers: if a non-seat0 one is started before a seat0 one, the former steals VTs from the later. If a seat0 X server can't open VTs, systemd-logind can't activate sessions for seat0, leaving user without sound or usb input support, for example. Patch xfree86_keep_non_seat0_from_touching_vts.patch from lp :~ubuntu-multiseat/xorg-server/trusty-matchseat fixes this. [Test Case] * Set up a multiseat system where your non-seat0 seats use non-KMS video drivers (you may need to tag another device in udev as master- of-seat in order to achieve it). * When LightDM/GDM tries to start a Xorg server for your non-seat0 seats, it will end up with the following error: (EE) No devices found. * After applying xfree86_allow_fallback_to_pci_bus_probe_for_non_seat0.patch, you can configure your seats in LightDM by setting appropriate xserver- config properties for each seat. However, you can't configure them in GDM. * After applying xfree86_add_matchseat_key_to_xorg_conf.patch, configure your seats properly and restart LightDM/GDM services (or reboot your computer) repeatedly. In some iterations, it may happen that logind can't activate graphical sessions for seat0. If it occurs, check output of command ps -FC Xorg and you'll see that a non-seat0 Xorg server has a lower PID than seat0 one. Moreover, the non-seat0 has opened a TTY, while the seat0 hasn't.
