[Andrzej Pietrasiewicz]

I followed your advice and multiseat setup still works. And still seat-1
resume problem remains.

I noticed that if I do (as root) a number of commands like:

# DISPLAY=:1 XAUTHORITY=/var/run/lightdm/root/:1 xrandr --output DVI-I-2 --off
# DISPLAY=:1 XAUTHORITY=/var/run/lightdm/root/:1 xrandr --output DVI-I-2 --auto

Then seat-1 comes back after suspend.

[Laércio de Sousa]

Anyway, have you tried to simplify your config files? For example, in your
udev rules, you don't need to tag anything as "seat0" explicitly, and in
your xorg.conf file, are you sure you need all that "Screen" and
"ServerLayout" sections? In principle just the "Device" sections would be
enough.

[Ubuntu-x-swat] [Bug 1209008] Re: [SRU] X doesn't work for video cards with non-KMS drivers on non-seat0 seats

[Andrzej Pietrasiewicz]

I GOT ENLIGHTENED.

I know what changed since yesterday. I don't have my printer installed
in the multisesat ubuntu, so I'm ocassionally booting into my Debian
install where I have my multiseat setup based on a Xephyr approach,
where both monitors are connected to the two heads of JUST ONE of the
graphics cards. So today the monitor of seat-1 was connected to TWO
cards. Hence seat0 saw two monitors and extended its desktop to both,
and seat-1 also saw one monitor. When I unplugged the reduntant cable,
it all behaves like yesterday: seat-1 wouldn't come back after resume.
That's good and bad news: the good news it that the world still works as
it is supposed, the bad news is that the seat-1 resume problem remains.
I need a break...

[Ubuntu-x-swat] [Bug 1209008] Re: [SRU] X doesn't work for video cards with non-KMS drivers on non-seat0 seats

[Andrzej Pietrasiewicz]

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? Is it possible that
lightdm 1.10.__4__ is causing problems?

You could also disable light-locker for user logged in seat-1 and see if
problem persists.

[Ubuntu-x-swat] [Bug 1209008] Re: [SRU] X doesn't work for video cards with non-KMS drivers on non-seat0 seats

[Andrzej Pietrasiewicz]

Regarding the doubt whether not coming back of seat-1 greeter is caused
by the screenscaver kicking-in: that is not the case. I checked again
and did a quick suspend and then resume and then looked up the
x-1-greeter.log and there was no line about the screensaver. It does
activate but far later than the failed suspend/resume.

[Ubuntu-x-swat] [Bug 1209008] Re: [SRU] X doesn't work for video cards with non-KMS drivers on non-seat0 seats

[Andrzej Pietrasiewicz]

Before suspend:
UIDPID  PPID  CSZ   RSS PSR STIME TTY  TIME CMD
root  1236  1223 12 55708 73248   0 20:56 tty7 00:00:10 /usr/bin/X -core

:1 -seat seat-1 -sharevts -auth /var/run/lightdm/root/:1 -nolisten tcp

After resume:
UIDPID  PPID  CSZ   RSS PSR STIME TTY  TIME CMD
root  1236  1223 10 93676 173432  1 20:56 tty7 00:00:13 /usr/bin/X -core
:0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch

:1 -seat seat-1 -sharevts -auth /var/run/lightdm/root/:1 -nolisten tcp

A big difference today is that the monitor assigned to seat-1 comes back alive 
BUT it extends the display of session at seat0!
In other words, today, after resume, both monitors provide a big desktop for 
session @ seat0.
I can't understand how it changed since yesterday. 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. Today, they tend to blink a couple of 
times, and seat0 mouse pointers appears offset to the right.

In /etc/lightdm/x-1-greeter.log I can see at the end:

[+61,04s] DEBUG: user-list.vala:1030: Adding/updating user hajaszek ()
[+398,50s] DEBUG: settings-daemon.vala:209: Screensaver activated

Please compare the times. The screensaver activates after about 5 minutes after 
the greeter is first displayed at system start.
I can't tell at this moment if this corresponds to the time when I 
suspended/resumed or to the time where screensaver kicked-in on an otherwise 
unavailable display.

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.

I would say this situation is even more annoying compared to the one
when seat-1 consistently refuses to show up after resume.

[Laércio de Sousa]

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.

[Ubuntu-x-swat] [Bug 1209008] Re: [SRU] X doesn't work for video cards with non-KMS drivers on non-seat0 seats

[Andrzej Pietrasiewicz]

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. I'm wandering which step of
restarting lightdm does the trick of waking it up fully? Because, as I
said before, the seat-1 is not completely lost after wakeup; if I
brutally restart lightdm it comes back, of course all graphical sessions
terminated and lightdm login screen displayed again at both seats.

My random guess is that the problem is in the X server. Perhaps for
waking up there is some code path which works in a similar way to what
probing used to work, that is,  it only searches for platform display
devices?

[Ubuntu-x-swat] [Bug 1209008] Re: [SRU] X doesn't work for video cards with non-KMS drivers on non-seat0 seats

[Laércio de Sousa]

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=

[Seat:seat-1]
autologin-user=

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

[Andrzej Pietrasiewicz]

The xserver-command with dpms does not work.

If I swap the cards in xorg.conf I can see symmetric behaviour: the card which 
is assigned to seat0 wakes up correctly,
but the other one does not, it's just this time that the cards are swapped.

[Ubuntu-x-swat] [Bug 1209008] Re: [SRU] X doesn't work for video cards with non-KMS drivers on non-seat0 seats

[Laércio de Sousa]

A possible workaround is preventing your seat-1 X server from
suspending. Include the following config to your lightdm.conf:

[Seat:seat-1]
xserver-command=/usr/bin/X -core -dpms -s 0

Anyway, if you swap your video cards bewteen seats (i.e. swap "seat0"
and "seat-1" occurences in your xorg.conf), do you see the same
behaviour?

[Andrzej Pietrasiewicz]

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. Any better ideas?

I've just updated xorg packages in my computer lab to
2:1.15.1-0ubuntu2.6. Multiseat is working pretty well (even with non-KMS
video devices on non-seat0 seats). No regressions observed at the
moment.

Hi Laércio,

SHAME ON ME

When I started looking for files to paste here, I had a closer look at
my xorg.conf:

Section "ServerLayout"
Identifier "Layout0"
Screen  0  "Screen0" 0 0
MatchSeat  "seat0"
EndSection

Section "ServerLayout"
Identifier "Layout1"

EndSection

Section "Monitor"

EndSection

Section "Device"

EndSection

Section "Screen"

Option "Stereo" "0"
Option "SLI" "Off"
Option "MultiGPU" "Off"

Option "SLI" "Off"
Option "MultiGPU" "Off"
Option "BaseMosaic" "off"
SubSection "Display"
Depth   24
EndSubSection
MatchSeat  "seat1"
EndSection

The problem is in naming. I dutifully named seat 0 "seat0", but I also 
dutifully followed the convention of naming
seat 1 "seat-1", with a dash between the "t" and the "1" - _EXCEPT_ in my 
xorg.conf...

When I did s/seat1/seat-1/g in my xorg.conf, the two seats appear correctly.
I did not stress test it too much, but will do now. If I have a problem I will 
let you know immediately.

I've been using multiseat setups for over a decade now and it has always
been at least a bit "hakish"; each and every dist-upgrade (I've been
using Debian testing, where dist-upgrades happen frequently) has been a
threat that thigs would stop working. What is proposed here looks like a
proper solution to multiseat setups. Thanks for your work!

Andrzej, please paste here the xorg.conf you've written for your NVIDIA
card, as well as your /var/log/Xorg.1.log, when you use the proprietary
driver.

[Ubuntu-x-swat] [Bug 1209008] Re: [SRU] X doesn't work for video cards with non-KMS drivers on non-seat0 seats

[Brian Murray]

Hello Richard, or anyone else affected,

Accepted xorg-server into trusty-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/xorg-
server/2:1.15.1-0ubuntu2.6 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at

[Ubuntu-x-swat] [Bug 1209008] Re: X fails to detect certain video cards on non-seat0 seats

[Laércio de Sousa]

** Description changed:

- From :
+ [Impact]
  
- > I have a multiseat setup with a primary on-board Intel graphics
- > device and a secondary Silicon Motion SM501 graphics card. My SM501
- > is configured via custom xorg.conf with siliconmotion ddx driver, so
- > it exposes no framebuffer devices to e.g. systemd-logind. The same
- > situation is seen e.g. for a NVIDIA graphics card with proprietary
- > drivers.
- > 
- > Every time I configure my system to assign my SM501 card with a
- > secondary seat, i.e. not seat0, my X server fails to start,
- > returning a "No devices detected" error. Nevertheless, when I assign
- > my SM501 card with seat0 and attach my Intel graphics device to
- > secondary seat (via loginctl), both seats load successfully.
- > 
- > Investigating the Xorg-server sources, I've found something related
- > to "platform bus". I don't know what is it at all, but whatever it
- > means, my Intel graphics card with its open-source drivers implement
- > it, but my siliconmotion driver doesn't.
- > 
- > In its current form, Xorg-server probes for platform bus devices as
- > well as "legacy" PCI bus ones only for seat0. For other seats, it
- > only probes for platform bus devices, hence it never reaches my
- > SM501 card, returning that "No devices found" error.
- > 
- > I don't know if there's a good reason for probing only platform bus
- > devices on non-seat0 seats, but this brings a problem for multiseat
- > setups like mine.
+ * 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.
  
- This same problem was encoutered by a user with two NVIDIA cards; see
- bug #976124.
+ Patch "xfree86_allow_fallback_to_pci_bus_probe_for_non_seat0.patch" from
+ lp:~ubuntu-multiseat/xorg-server/trusty-matchseat fixes this.
  
- A patch was supplied to the upstream bug report, and this patch seems to
- fix the problem.
+ * 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).
  
- 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. 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 has

[Ubuntu-x-swat] [Bug 1209008] Re: X fails to detect certain video cards on non-seat0 seats

[Laércio de Sousa]

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.

[Laércio de Sousa]

Hi guys!

Glad to see that my patch works for you. I left Ubuntu some time ago to
try some other systemd-enabled distros (Fedora and openSUSE) for better
multiseat support. Thanks to your collaboration, I will be back to
Ubuntu soon.


BTW, the following patch is a little bit more appropriate for Xorg 1.13, used 
in raring.

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.

Created attachment 82364
Go further with "legacy" PCI bus probe on non-seat0 seats when no platform bus 
devices are found

I have a multiseat setup with a primary on-board Intel graphics device
and a secondary Silicon Motion SM501 graphics card. My SM501 is
configured via custom xorg.conf with siliconmotion ddx driver, so it
exposes no framebuffer devices to e.g. systemd-logind. The same
situation is seen e.g. for a NVIDIA graphics card with proprietary
drivers.

Every time I configure my system to assign my SM501 card with a
secondary seat, i.e. not seat0, my X server fails to start, returning a
"No devices detected" error. Nevertheless, when I assign my SM501 card
with seat0 and attach my Intel graphics device to secondary seat (via
loginctl), both seats load successfully.

Investigating the Xorg-server sources, I've found something related to
"platform bus". I don't know what is it at all, but whatever it means,
my Intel graphics card with its open-source drivers implement it, but my
siliconmotion driver doesn't.

In its current form, Xorg-server probes for platform bus devices as well
as "legacy" PCI bus ones only for seat0. For other seats, it only probes
for platform bus devices, hence it never reaches my SM501 card,
returning that "No devices found" error.

I don't know if there's a good reason for probing only platform bus
devices on non-seat0 seats, but this brings a problem for multiseat
setups like mine.

I've wrote a small patch that solves my problem, going further with PCI
bus probe, while tries to keep the current behavior if a platform bus
device is found on secondary seats. Please consider applying it, or
giving another solution.

Thanks in advance!

These did not go away when you added the 'master-of-seat' udev tag?

This same problem was encoutered by a user with two NVIDIA cards; see
bug #976124.

A patch was supplied to the upstream bug report, and this patch seems to
fix the problem.

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.
