Hello, When using the ppa:x2go/stable repository, something seemed strange when I ran the update manager in Ubuntu 14.04 and Ubuntu 16.04. I received a message about a partial upgrade I've never seen since using Ubuntu. I've attached the message. After running this partial upgrade, I started experiencing the flickering problems. Removed x2goserver entirely, and did a fresh install of the most update to date version. Still experiencing the flickering problems.
I uninstalled everything from x2goserver on our system. Also uninstalled any lingering package versions that might conflict with trying to install from the Saimaa repository. After cleaning, I installed x2goserver from the Saimaa repository. I no longer experience the flickering when maximizing/minimizing or moving the window from side-to side. Everything is working fine like it was prior to the most recent update from the ppa:x2go/stable repository. I think I'm going to stick with the Saimaa repository for now until the bugs are fixed from the ppa:x2go/stable repository. Also going to stick with x2goclient 4.1.0.0 where there is no issue with clicking the session panel. I can click where I'm accustomed to clicking again. Why are there 2 repositories for x2go and which one should we use for the long-term? Any help would be appreciated. h. ________________________________ From: x2go-user <x2go-user-boun...@lists.x2go.org> on behalf of h i <qpile...@outlook.com> Sent: Friday, March 9, 2018 4:23 PM To: x2go-user@lists.x2go.org Subject: Re: [X2Go-User] Problems after upgrading to recent x2go-server and x2go client releases Mihai, Thanks for your response.

I think I might have to roll-back to the previous x2goserver version.

Interesting. Yeah, I never had an issue with the sensitive area.

What is Saimaa release, and why are there two separate releases for x2go now? Is the saimaa release from here: https://launchpad.net/~x2go/+archive/ubuntu/saimaa Thank you for your help. h.
