Bug#150: Cinnamon 2.2 does not work
by Michael DePaulo 20 Feb '16

20 Feb '16

I just tested Cinnamon 2.2.13 and it does not work properly with X2Go. Basically, Cinnamon resorts fo "fallback mode", which is not the same as Cinnamon2d. More details are below. Note that GLX is enabled, and I ran the "Custom Desktop" command: cinnamon-session-cinnamon2d ---- When I connect, only gnome-panel is running. (Basically, gnome-flashback is running, although package gnome-session-flashback is not installed) It is very different from cinnamon2d, which works locally, and there are many bugs in this version of gnome-panel/gnome-flashback. For example, you cannot even set a desktop background using the GUIs. I also see a dialog with the text: Do you want to restart Cinnamon? Cinnamon just crashed. You are currently running in Fallback Mode. If I click yes, the dialog comes back up. If I click No, I the dialog closes, and the session is usable, but it's very buggy for aforementioned reasons. This is just a VM I setup for the specific purpose of testing Cinnamon compatibility with X2Go. I have the GLX extension enabled on my test system (/etc/x2go/x2goagent.options has the line to disable GLX commented out) - Linux mint 17 qiana (based on Ubuntu 12.04 trusty) 64-bit - All latest level 1, 2 and 3 OS updates installed. - cinnamon version 2.2.13 - Custom Desktop specified in x2goclient: cinnamon-session-cinnamon2d - x2goserver & x2goserver-xsession: 4.0.1.15-0~847~ubuntu14.04.1 - nxagent & x2goagent: 2:3.5.0.27-0~446~ubuntu14.04.1 I've attached the contents of my .xsession-x2go-errors file. Note the following session files: batmin@mint-q /usr/share/cinnamon-session/sessions $ ls cinnamon2d.session cinnamon.session batmin@mint-q /usr/share/cinnamon-session/sessions $ cat cinnamon2d.session [Cinnamon Session] Name=Cinnamon (Software Rendering) RequiredComponents=cinnamon;cinnamon-settings-daemon;cinnamon-screensaver;nemo-autostart;nm-applet; DesktopName=X-Cinnamon batmin@mint-q /usr/share/xsessions $ ls cinnamon2d.desktop cinnamon.desktop batmin@mint-q /usr/share/xsessions $ cat cinnamon2d.desktop [Desktop Entry] Name=Cinnamon (Software Rendering) Comment=This session logs you into Cinnamon (using software rendering) Exec=cinnamon-session-cinnamon2d TryExec=/usr/bin/cinnamon2d Icon= Type=Application X-Ubuntu-Gettext-Domain=cinnamon X-GNOME-Provides=cinnamon2d batmin@mint-q /usr/share/xsessions $ cat /usr/bin/cinnamon-session-cinnamon2d #! /bin/sh exec cinnamon-session --session cinnamon2d "$@"

Bug#707: BPG as bitmap compression engine in NX
by Mike Gabriel 20 Feb '16

20 Feb '16

Package: libxcomp3 Severity: wishlist Hi all, By Savko Sergey I have just been pointed to the upcoming BPG image compression library [1]. Quoting their website: """ BPG (Better Portable Graphics) is a new image format. Its purpose is to replace the JPEG image format when quality or file size is an issue. Its main advantages are: High compression ratio. Files are much smaller than JPEG for similar quality. Supported by most Web browsers with a small Javascript decoder (gzipped size: 55 KB). Based on a subset of the HEVC open video compression standard. Supports the same chroma formats as JPEG (grayscale, YCbCr 4:2:0, 4:2:2, 4:4:4) to reduce the losses during the conversion. An alpha channel is supported. The RGB, YCgCo and CMYK color spaces are also supported. Native support of 8 to 14 bits per channel for a higher dynamic range. Lossless compression is supported. Various metadata (such as EXIF, ICC profile, XMP) can be included. """ We should take a look at this new compression library and check if it is usable in NX.

Bug#826: shadow sessions inside nxagent sessions fail
by Mike Gabriel 20 Feb '16

20 Feb '16

Package: nxagent Severity: important Version: 3.5.0.29 Control: forwarded -1 https://github.com/ArcticaProject/nx-libs/issues/6 We just tried to run cascaded sessions with one of them being a desktop sharing session: (a) from client (host-A) launch X2Go session to a remote server (server-B) (b) from X2Go session on server-B launch a remote desktop sharing session with :0 on remote host-C Result: a black nxagent window appears (inside the X2Go Session on server-B) that accepts mouse and keyboard input (which both arrive on host-C via desktop sharing). If I manage to move a window via the desktop sharing session, the black nxagent window does some screen updates, but no full view of the remotely shared desktop appears.

Bug#923: .xsession-x2go-errors improvements
by Orion Poplawski 22 Oct '15

22 Oct '15

Package: x2goserver Version: 4.0.1.19 First issue is that ~/.xsession-x2go-errors is always appended to so it grows forever. It should at least get rotated to .old file. Second is with shared NFS home directories, multiple X2Go sessions get logged to the same file which is confusing. I would suggest putting the host name into the log file name. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 http://www.nwra.com

x2go client session kicks user back to the session login screen
by Real, Elizabeth (392K) 21 Oct '15

21 Oct '15

Hello, I have a user who is not able to connect to an x2go server using x2go client for Mac. When I connect to the x2go server in question I am able to successfully connect and login. I’ve compared settings between the user’s and my Mac x2go client and they are identical. I’ve attached screen shots of the client session details. The last messages in the session are: * Info: Your session was closed before reaching a usable state. * Info: This can be due to the local X server refusing access to the client. * Info: Please check authorization provided by the remote X application. * Session: Session terminated at x2go client: v4.0.4.0 xquarts: v2.7.7 Tried uninstalling the x2go client and installing it again but that did not help. Same errors while attempt is made to connect to x2go server. Please advise. Thank you, Liz

debian jessie general protection trap in libNX_X11.so.6.2 caused by some apps
by Jean-Francois Dagenais 02 Oct '15

02 Oct '15

Hi all! Long time x2go user. Just remade my box with debian jessie. Followed the server instructions steps. I can run xterm and other programs, but some (like gnome-terminal, xfce-terminal, mate-terminal ... and others) cause x2goagent to crash with: traps: x2goagent[8626] general protection ip:7fdf1317fe6d sp:7ffe79b7dd70 error:0 in libNX_X11.so.6.2[7fdf13133000+123000] This is using today's nightly build. Wondering how to proceed now. Sources build to get more debug information? FYI, I am a general software and linux kernel developer but am not familiar with the x2go project development. Thanks!

The $STARTUP env variable will be set for every Xsession based X11 session on a Ubuntu or Debian (and alike). Please do a grep on /etc/X11 and see its output (grep -r STARTUP /etc/X11). In case you want to use $STARTUP in your own scripts, please know that it is not a good idea to use that var name on Debian nor Ubuntu systems. Using X2GO_STARTUP or any other variable name will not work with existing scripts in /etc/X11/Xsessions.d. Thus, closing this issue and tagging as "not-a-bug".
