arbitrary no-connection issues with »Warning: No data received from remote proxy within 30 seconds.«
Dear X2go developers and users,
since some time I sometimes cannot connect with my client to the server.
The system the server is running on gets also used as a desktop machine. I think the issue is surfaces when a second user logs into the system using for example GNOME’s switch-user-applet.
I do not know when this problem started. I am using Debian unstable/sid. A big change was the upgrade to GNOME 2.28 and the X.org server (1:7.4 +4).
When the problem occurs nxproxy -S
$ nxproxy -S

Further tests showed that the problem also occured if only one user was logged in.
I do not know when this problem started. I am using Debian unstable/sid. A big change was the upgrade to GNOME 2.28 and the X.org server (1:7.4 +4).
I filed bug report #550277 in the Debian BTS against nxproxy [1].

Could someone on this list please confirm that everything works for him/her using Debian sid/unstable.
Thanks,

I just want to add that it is also not related to a missing loopback device on my system as last time [2]. (The error messages were also different back then.)
$ ip link

Yesterday and today it worked again, although I did not change anything related to X2go.
I will try to find the different packages in some days.
