Subject: lightdm: on login, lightdm starts a second xserver on the next tty, with mirrored xsession
Date: Sat, 05 Dec 2020 15:53:04 +0100
Package: lightdm
Version: 1.26.0-4+devuan1
Severity: normal

Hello,

after installing beowulf-proposed-updates on my lxqt-beowulf computer, when
logging in at the lightdm (1.26.0-4+devuan1) logon screen (tty7), a second
xserver gets startetd on tty8, which mirrors the xsession on tty7. Going back
to tty7, I have to (lightdm-)login again to the running xsession. After further
tty switching, the xserver0 on tty7 exits, while xserver1 on tty8 still serves
the "common" Desktop. Now the system is stable as before the update, with the
Desktop session running on tty8, while tty7 is not available.

The issue can be reproduced reliably, a downgrade of lightdm to the "beowulf
main" version (1.26.0-4) resolves it.

Steps to reproduce (with respective time in the attached lightdm.log):


1.) restart lightdm (init.d) +0.00s (12:20, see lightdm/x-0.log.old,
seat0-greeter.log.old):
                tty7 [gtk-greeter] -> tty8 [n/a]

2.) login @tty7 as "florian" [Desktop] +44.08s
                        [+48.59s] second xserver started (12:21, see
lightdm/x-1.log)

3.) switch from tty7 [Desktop] -> tty8 [Desktop, mirrored] ca. +120s

4.) switch from tty8 [Desktop] -> tty7 [gtk-greeter, one flicker] +235.23s
(12:24, see lightdm/x-0.log, end of seat0-greeter.log.old, beginning of
seat0-greeter.log)

5.) login #2 @tty7 [Desktop, mirrored] +386.28s

6.) switch from tty7 [Desktop] -> tty8 [Desktop, mirrored] ca. +500s

7.) switch from tty8 [Desktop] -> tty7 [n/a] ca. +620s

8.) switch around and find every thing stable, with the desktop running on tty8


When I do the second login @tty7 at 5.) with another user, the session gets
started, but always after returning to tty7 from another tty, the gtk-greeter
is presented. In the meantime, the first user's session on tty8 remains
unlocked.

Subject: Re: bug#529: lightdm: on login, lightdm starts a second xserver on the next tty, with mirrored xsession
Date: Thu, 10 Dec 2020 16:03:56 -0500
Hello,

Thank you for your report! The only changes between the versions in
question were to add pam-elogind support, and add a particular setting
to the default lightdm config.

Would you please share the results after you change the value of
"xserver-share" to "true" or omitted in file
/usr/share/lightdm/lightdm.conf.d/01_debian.conf.

This sounds directly related to your issue, and the explicit default
of false was added to resolve #493.

B. Stack

Date: Fri, 11 Dec 2020 21:17:35 +0100
Thank you, B. Stack,

setting

	xserver-share=true
in
	/usr/share/lightdm/lightdm.conf.d/01_debian.conf

resp. uncommenting it in

	/etc/lightdm/lightdm.conf

solves the issue.

If this is wanted new behavior, or my configuration is a tolerated
corner case, it perhaps should get mentioned in the release notes.
(closing)

Best regards,
Florian

Date: Sun, 13 Dec 2020 10:28:40 -0500
I got hit with this bug on chimaera when trying to connect via x11vnc. The
auth failed.

ps ax |grep auth gives me

 6147 tty7     Ssl+   0:00 /usr/lib/xorg/Xorg :0 -seat seat0 -auth
/var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
 6270 tty8     Ssl+   0:02 /usr/lib/xorg/Xorg :1 -seat seat0 -auth
/var/run/lightdm/root/:1 -nolisten tcp vt8 -novtswitch


After setting 'xserver-share=true' in
/usr/share/lightdm/lightdm.conf.d/01_debian.conf
fixes the problem. Only one display shows up with ps and I can connect
with vnc.

After Greg and my testing, it appears we can revert to xserver-share unset
(default true) which will fix this issue and if we have
debian-pulseaudio-config-override and libpam-elogind installed then
accessibility features through orca still work. The best of both worlds!

Best wishes

Mark
