[Xrdp-devel] Suddenly: X server for display 11 startup timeout

OK. Got this one.... though I'm confused as to how this happened.

The problem, as I suspected, was not xrdp. It was a permissions error
on /tmp. The users in question couldn't for their socket to start
their x session.

Just needed a good night's sleep to figure out how to trouble shoot it.

Hello.

I hope this isn't a stupid question, but I had a really good thing
working with xrdp for years. Suddenly, I rebooted the server, and
xrdp no longer works. I do not understand why. I didn't change any
config or install any new packages -- just *poof* stops working. So,
I can only suspect that something was changed months ago, without a
reboot.

I'm runing debian wheezy, with the xrdp 5 that is in the default repository.

Now when I try to connect, I get "error problem connecting"

If I look in the xrdp-sessman.log file (or run it in the foreground) I get:

[20150321-22:08:27] [INFO ] scp thread on sck 7 started successfully
[20150321-22:08:27] [INFO ] granted TS access to user jill
[20150321-22:08:28] [INFO ] starting Xvnc session...

[20150321-22:08:38] [ERROR] X server for display 11 startup timeout
[20150321-22:08:38] [ERROR] another Xserver is already active on display 11

[20150321-22:08:38] [DEBUG] aborting connection...

It says another X server is active... which, of course, is not true.
I don't even start x on boot, or any kind of display manager.

To my great consternation, I have googled this, and found no insight
whatsoever. The couple of posts that say they fix it talk about
adding gnome as the solution. Please... Another said add pixman and
libxfonts... mine were already installed. I reinstalled these, but it
still didn't help.

I'm not seeing anythign particularly weird in my /var/log/syslog and
It doesn't look like it is writing to my Xorg.0 log.

I don't have direct access to this machine -- I can only hit it
remotely through ssh, and up to a few hours ago, through xrdp.

Can someone give me a hand here? Where do I go next? How do I
trouble-shoot this? Is this a bug?

Thank you.
