Hello,
<div><br>
</div>
<div>When using the <span>ppa:x2go/stable repository,</span> 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.<br>
<div><br>
</div>
<div>I uninstalled everything from x2goserver on our system. Also uninstalled any lingering package versions that might conflict with trying to install from the <span>Saimaa repository.</span></div>
<div><br>
</div>
<div><span></span>After cleaning, I installed x2goserver from the <span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">Saimaa
repository.</span></div>
<div><br>
</div>
<div><span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;"></span>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 <span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">ppa:x2go/stable
repository. I think I'm going to stick with the Saimaa <span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">repository
for now until the bugs are fixed from the <span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">ppa:x2go/stable </span> <span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">repository.

<div>
<div style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
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.</div>

are there 2 repositories for x2go and which one should we use for the long-term?</span></span></span></div>
<div><span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;"><span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;"><span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;"><br>

<div>Any help would be appreciated.</div>
