Bug#1262: autologin and ssh key options are incompatible
by Antonio Russo 25 Feb '18

25 Feb '18

Package: x2goclient Version: 4.1.1.1 Commit fe4408b12c982b81c56c52f37230865f4e9f41ea prevents an autologin attempt if an ssh key is specified. The "Session Preferences" window in the client should transparently express this limitation. I.E., if an ssh key is specified, the "try auto login" checkbox should be grayed out, and vice-versa.

x2go Zorin OS 12.2
by Robert Dinse 24 Feb '18

24 Feb '18

The stable release of x2goserver works on Zorin except for the xrandr version issue (it uses version 2, Zorin wants version 3). The nightly build earlier x2goagent cored dumped: Feb 23 18:53:48 zorin kernel: [ 1979.107382] traps: x2goagent[2003] general protection ip:7f52e6a66512 sp:7ffff6fae0b0 error:0 in libc-2.23.so[7f52e69e2000+1c0000] I was going to do a backtrace on the core but I had installed the stable release again. So I re-installed the nightly build to re-create but it no longer core dumps, still however it immediately exits (this is using mate for the desktop and mate is working with the stable except that I have to manually set the geometry with xrandr. So now no core, no errors that I can find in logs, and I don't know where to go from here.

X2go on Zorin
by Robert Dinse 24 Feb '18

24 Feb '18

The stable build of x2go presently works on Zorin except xrandr version issues but the Nightly Builds does not. Nightly builds nxagent core dumps when the session tries to start. Got to go now but will provide more details, try to get a backtrace if I can, later when I get back. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

I spaced, sorry, this is installed on Ubuntu 17.10 both client and server. Also virt-manager does not work properly over x2go, using the resize to virt option sizes to 600x800 instead of the virtual display size. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

X2go Nightly New Bugs

I have nightly builds installed, in part becuase of xrandr compatibility issues with the stable version and in part to help with the debugging process.

Attention: All X2Go Server Admins! Upcoming major X2Go (Server) Release
by Stefan Baur 23 Feb '18

23 Feb '18

Hi! We would like to inform you that a new X2Go stable version is about to be released, most likely around March 1st, 2018. In fact, the release is already ready - we are actively holding back the binary package builds at the moment so you have a chance to react. If you have set all your servers to automatically update to new releases, we suggest that you disable this mechanism now until you have verified that the new version works for you. If, on the other hand, you test and deploy updates manually, no change is required. Please test the new X2Go stable version as soon as it becomes available, so that we have a chance to fix any remaining issues that slipped through our testing early on. Should you encounter major problems with the new version, we suggest switching to the ESR branch, codenamed "saimaa". This branch will continue to receive security updates, but is (and will remain) based on what you currently know as "stable". Some packages, like cups-x2go, pinentry-x2go, x2godesktopsharing, x2go*bindings, are not part of saimaa and thus must be pulled from the regular repository. This requires proper setting of repository priorities, so packages existing in the saimaa repository take priority over packages from the regular repository. If you need assistance with this, please make sure you have disabled automatic updates before doing anything else, then ask for help either in our IRC channel #x2go on freenode, or on the x2go-user Mailing List. However, if you are a daredevil and already want to access binary packages that pretty much match what we are going to release soon, temporarily change your X2Go repository entry to the timestamped heuler repository bearing the timestamp of 2018-02-16, pull the update, then switch your repository back to stable. Note that this is a procedure not recommended for the average user. Try and use at your own risk.

session files in /tmp
by yk+bug+x2go＠64.re 21 Feb '18

21 Feb '18

On Linux, the X2Go server stores the session files in /tmp/.x2go-* . Now, whenever a coworker leaves for vacation, those files are not getting updated and thus get deleted by tmpwatch on CentOS 6 or systemd-tmpfiles on CentOS 7; when the coworker comes back and tries to resume the session, it goes into failed mode since those files are gone, with no possibility of recovery. The current workaround that I set up is to exclude /tmp/.x2go-* from clean-up (e.g.[1]), but to prevent having to do it on every machine to which we want to connect, it would be nice to move the folder to a place that is not cleaned (at least as often). Although the Linux Filesystem Hierarchy Standard (FHS) has been widely disputed, it seems to be an admitted convention to put PID/lock/socket files and the like in /run (or /var/run). Is there a specific reason why those files are in /tmp and not in /var? [1] On CentOS 7 for systemd-tmpfiles: # cat /etc/tmpfiles.d/x2go.conf #Type Path Mode UID GID Age Argument # Exclude X2Go session files x /tmp/.x2go-*
