Ubuntu Directions to fix qt.qpa.xcb: X server does not support XInput 2?
by James Bowery 10 Oct '20

10 Oct '20

Looking up qt.qpa.xcb: X server does not support XInput 2 I discovered https://community.rstudio.com/t/x2go-and-rstudio/29704/5 which linked to https://wiki.x2go.org/doku.php/wiki:development:glx-xlib-workaround but following the directions for Ubuntu, I get: E: You must put some 'source' URIs in your sources.list Moreover, the directions are for Ubuntu 14 and we're on 20, so I'm not even sure the directions are up to date if, indeed, the problem with x2go still exists after all this time.

Disconnect Acts Like CTRL-s Press
by James Bowery 09 Oct '20

09 Oct '20

If I lose my internet connection, it seems to, in effect, press CTRL-s on the remote terminal window. This is most frustrating as I will frequently leave a process running over night only to discover in the morning that it has paused execution. Is there anyway to prevent this from happening?

Reconnection results in Major opcode of failed request: 88 (X_FreeColors)
by James Bowery 08 Oct '20

08 Oct '20

After connection is restored, a program that had, during the outage, plotted a graph, fails to show the graph on the x2go client with this message: X Error of failed request: BadAccess (attempt to access private resource denied) Major opcode of failed request: 88 (X_FreeColors) However, rerunning the program in the same terminal window succeeds.

new x2go version fail to connect
by gian sisal 05 Oct '20

05 Oct '20

Hi everyone, I just updated my X2Go windows client versione from 4.1.2.0 to 4.1.2.2, I saw a change in session preferences: under session type there was "connect to local desktop", now I see"X2Go/X11 Desktop Sharing". Unfortunately now I'm no longer able to connect to my remote systems. It seems like the software crashes and closes when I try to login. I think I downgrade again to 4.1.2.0. however: is it normal? Am I missing something? Thanks in advance. Best Regards. Gf

No input accepted on subsequest sessions
by May Doušak 03 Oct '20

03 Oct '20

Hi, I use x2go on a few computers (both servers and clients) and have problem on one of them. I'm connecting to xfce (if that matters) on ubuntu 20.04. On my first connection (i.e. when xfce4-session starts), everything works OK. When I disconnect (close x2go window) and reconnect to the same session (no matter what I use - "xdcmp session", "X2go desktop sharing --> resume", etc), I can only "view" what's on the screen and no input is accepted from keyboard or mouse. It doesn't even detect mouse movement (if I hover over something, it doesn't work). Funny enough, I can resize window size and it words as expected (it increases resolution). If, however, I open a new session or kill existing xfce4-session (using ssh), the new connection accepts input without any problems - until I close the connection and reconnect, that is. Does anyone have an idea what could be done to make it work? Thanks, May

x2go much slower than vnc?
by Johann Petrak 01 Oct '20

01 Oct '20

I just learned about x2go and wanted to try it out for a remote session to a host I have so far done using vnc serving a xfce desktop. But sadly my observation is that x2go is *much* slower and less responsive than VNC. For example just moving around a window on the desktop (same size) works smoothly with VNC but is done in a very coarse fashion in x2go with the window jumping around slowly and with considerable delay. Both connections go over the same ssh tunnel, same kind of LAN so all other things the same, the problem must lie with x2go or the x2go settings. Is there any explanation for this or anything that could be changed to increase the speed of x2go? Is x2go not *supposed* to be faster than VNC? I have experimented a bit with the connection speed and compression settings but that did not change anything either.

x2go disconnects on paste (openSUSE Tumbleweed)
by Tristan Miller 01 Oct '20

01 Oct '20

Dear all, Today I updated from openSUSE Tumbleweed 20200708 to 20200724, and now whenever I try to paste the clipboard contents into a single application launched remotely via x2go, the x2go session disconnects and terminates. Does anyone else here have the same problem, or know what the culprit might be? Regards, Tristan

Losing mouse click ability and keyboard events
by Nicolas Ecarnot 01 Oct '20

01 Oct '20

Hello, First post, thank you for welcoming me here. From an Ubuntu 20.04 client to an Ubuntu 20.04 server, the default repository install is working out of the box, all is nice. But from times to times (random but around 15 min. ), with no obvious reasons, I'm losing the ability to click : - the display is still fine - the mouse cursor is still drawn - when moving the cursor, it is reacting to the windows borders, URL links, any sensitive parts of the display - but no mouse button click seems to be sent - no keyboard stroke seems to be sent either When killing the client and connecting again, the display is still fine, but the same problem remains. I tried to run the x2go client from a terminal to have a look at what could be wrong, but nothing obvious came to my mind. I tried to have a look at the server's log but I found none. I don't know if I could run the client and/or the server with additional verbosity to try to get more hints? Does that look like something familiar? Thank you -- Nicolas ECARNOT
