Bug#1269: X2go server crashes on Ubuntu 16.04
by Philip Kollmannsberger 14 Mar '18

14 Mar '18

package: nxagent Version: 3.5.99.15-0~201803072246~ubuntu16.04.1 Severity: grave We have the same problem here after upgrading x2go from 4.0.1.22 to 4.1.0.0. It is independent of client version and OS (both Linux and Windows), and seems to be related to Xinerama: - when enabling Xinerama support in the client, x2go works in fullscreen, but leads to a crash in windowed mode as soon as the window is resized or moved to a different display. - when disabling Xinerama support, everything seems ok The log shows a segfault of nxagent, exactly as described above.

Bug#1269: X2go server crashes on Ubuntu 16.04

Package: nxagent Version: 3.5.99.15-0~201803072246~ubuntu16.04.1 Severity: grave I can confirm this bug and would like to ask that its severity is changed to GRAVE, as it makes x2go server unusable. In a nutshell: attempt of starting a session on a client causes a window to briefly appear and then disappear. Server syslog shows a segfault: kernel: [ 3899.187248] nxagent[7306]: segfault at 0 ip 0000558c9d0045fb sp 00007ffdad91c1f0 error 4 in nxagent[558c9cf39000+432000] In my case, a routine system update (apt-get update && apt-get dist-upgrade) rendered a production server unusable, with no way to rollback the botched x2go update. The issue did not appear before the update. I also recreated the issue on a vanilla Ubuntu 16.04 server running in a VM. I use this install as a basis for the description below. Versions - server: x2goserver: 4.1.0.0-0~1517~ubuntu16.04.1 nxagent: 3.5.99.15-0~201803072246~ubuntu16.04.1 uname -a: 4.4.0-116-generic lsb_release -d: Ubuntu 16.04.4 LTS Versions - client: x2goclient: 4.0.5.1-1 uname -a: 4.13.0-32-generic lsb_release -d: Ubuntu 16.04.3 LTS Steps to reproduce: 1. Install Ubuntu 16.04 server in a VM (from ubuntu-16.04.3-server-amd64.iso downloaded from ubuntu.com) 2. Update the system (apt-get update && apt-get dist-upgrade) and reboot. 3. Install x2go as described on https://wiki.x2go.org/doku.php/wiki:repositories:ubuntu All commands run as root (sudo su -) apt-add-repository ppa:x2go/stable apt-get update apt-get install x2goserver x2goserver-xsession --no-install-recommends 4. Install minimal XFCE desktop: apt-get install xfwm4 xfce4-panel xfce4-settings xfce4-session xfce4-terminal xfdesktop4 xfce4-taskmanager xfce4-appfinder xfce4-artwork --no-install-recommends 5.
