Re: [X2Go-User] X2Go server, nxagent causes segfault

2018-03-20 Thread Kalle Tuulos


Hello

I just upgraded my Ubuntu setup with a normal apt-get upgrade and 
nx-agent version 2:3.5.99.16-0~201803162252~ubuntu16.04.1 was installed. 
The segfault problem went away, X2Go works again "as specified".


BR,

Not sure if this is the same for all my users though.

Re: [X2Go-User] X2Go server, nxagent causes segfault

2018-03-12 Thread Norman Gaywood

I'm thinking it may be the latest update to libNX_X11 (a few days ago)

But the x2go repo does not contain old versions, so I can't test the
downgrade.

Anyone know how to downgrade?

libNX_X11-6-3.5.99.15-0.0build1.1.git20180308.2971.main.fc27.x86_64

AEDT.
