** Description changed: - From https://bugs.freedesktop.org/show_bug.cgi?id=66851: + [Impact] - I have a multiseat setup with a primary on-board Intel graphics - device and a secondary Silicon Motion SM501 graphics card.

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). - Note that this bug only affects detection of cards when X is passed the - '-seat' argument with a seat name OTHER than seat0. Thus, this only - happens in multiseat setups. + 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.

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

Hi there! Oleg Samarin, who introduced the master-of-seat concept in systemd- logind, has recently submitted a patch for xorg-server that introduces a new capability: MatchSeat. The concept is explained here: http://lists.x.org/archives/xorg-devel/2013-September/037945.html and the patch is available here: http://lists.x.org/archives/xorg-devel/2013-September/037946.html As you can see, it includes my small patch for fixing that no devices detected error. In fact, I've shared privately this patch with him before opening bug freedesktop#66851, and I believe it makes more sense to include my patch in a more comprehensive work like his. I strongly recommend that you try this new patch. I'll finally begin my switch back to Ubuntu tomorrow, so I can upload to Multiseat PPA soon. -- 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: X fails to detect certain video cards on non-seat0 seats Status in X.Org X server: Confirmed Status in “xorg-server” package in Ubuntu: Confirmed Status in Fedora: Unknown Bug description: From https://bugs.freedesktop.org/show_bug.cgi?id=66851: I have a multiseat setup with a primary on-board Intel graphics device and a secondary Silicon Motion SM501 graphics card.

[Desktop-packages] [Bug 1209008] Re: X fails to detect certain video cards on non-seat0 seats
(continuing the conversation from bug #976124 here since this bug report seems more relevant) but there were problems - huge memory leaks. In attached zip are log files for xorg and lightdm. My .xsession-errors was full of error lines: dconf-CRITICAL **: unable to create file '/home/alberts/.cache/dconf/user': Permission denied. dconf will not work properly. And at least one line of this: WARNING: Could not get session id for session. Check that logind is properly installed and pam_systemd is getting used at login.

[Desktop-packages] [Bug 1209008] Re: X fails to detect certain video cards on non-seat0 seats
These did not go away when you added the 'master-of-seat' udev tag? I did not test it... But memory leaks is not releated to this bug. I think it caused because o permission denied error. Memory leaks was for gnome-settings-daemon, indicator-applet-complete if I remember correctly. Xorg itself worked ok. So patch from upstream fixes problem failing to detect video card for seats other than seat0. -- 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: X fails to detect certain video cards on non-seat0 seats Status in X.Org X server: Confirmed Status in “xorg-server” package in Ubuntu: Confirmed Status in Fedora: Unknown Bug description: From https://bugs.freedesktop.org/show_bug.cgi?id=66851: I have a multiseat setup with a primary on-board Intel graphics device and a secondary Silicon Motion SM501 graphics card.
