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 XXXX" option where "XXXX" != "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. [Regression Potential] * Very low. All these patches were well tested in xorg-server "trusty" package available in ppa:ubuntu-multiseat/ppa.
