#269924 — lightdm errors

If this is off topic, let me know a better forum please.

Overnight, I'm getting errors every 2s from lightdm.
Jun 04 01:57:01 cerberus lightdm[1546921]: xrandr: cannot find mode 1920x1200
Jun 04 01:57:03 cerberus lightdm[1546948]: xrandr: cannot find mode 1920x1200
Jun 04 01:57:05 cerberus lightdm[1546982]: xrandr: cannot find mode 1920x1200
Jun 04 01:57:07 cerberus lightdm[1547009]: xrandr: cannot find mode 1920x1200

and so on.

I have three monitors on the onboard connectors.  The left (1920x1080) is
tall, the other two (1920x1200) are wide.  The default situation was that
the monitors were in the wrong order, and the left one was sideways.  I
wrote a script which used xrandr to fix this in XFCE, though I rarely need it.

Anyhow I don't know where that error is coming from.  There's a line

eben@cerberus:/etc/lightdm$ grep fixm *
lightdm.conf:# greeter-setup-script = /export/bin/fixmonitors

but as you see it's commented out.  And the string "1920x1200" appears
nowhere in the config files:

eben@cerberus:/etc/lightdm$ grep 1920 *
eben@cerberus:/etc/lightdm$

Does anyone know how to increase logging in lightdm so I can see why it's
complaining?  Thanks.

I suggest you use arandr to set things as you wish, then export a
script to automate that setup. Then call the script from your session
manager.

Or, since you are using XFCE, Applications -> Settings -> Display and
set things up there.

I did that a while back, when I set the monitors up this way.  They were
arranged correctly once I logged in.  It's just in lightdm that they were
wrong.  They are correct now (I actually don't know why, unless it's
ignoring the hash mark for that line), but I get those errors, which might
be related to it not going into suspend overnight.

I modified lightdm's config on 20 May (so says my log), but:

eben@cerberus:~$ sudo journalctl | grep xrandr | uniq -c --check-chars=6
    3015 May 24 21:25:03 cerberus lightdm[2714286]: xrandr: cannot find mode

There are no errors on the 23rd related to xrandr, so I suspect something
happened on the 24th.

<investigation happens>

The logged event right before lightdm started acting up was
May 24 21:25:01 cerberus dbus-daemon[1362]: [session uid=1000 pid=1362]
Activating service name='org.xfce.Xfconf' req>
May 24 21:25:01 cerberus dbus-daemon[1362]: [session uid=1000 pid=1362]
Successfully activated service 'org.xfce.Xfco>

Maybe that dbus update was bad?  Or I only updated part of it or something?
