Bug#63: Current Cairo test suite segfaults x2goagent
by Moritz Struebe 13 Jun '16

13 Jun '16

Package: x2goagent Version: 3.5.0.16-0 x2goagant segfaults when running the cairo test suite. (The current version only compiles on Wheezy) This can be reproduced running: git clone git://anongit.freedesktop.org/git/cairo cd cairo ./autogen.sh ./configure make make test As quite few tests fail Bugs #62 and #35 might be related to Cairo.

Bug#78: NX_xrandr lacks support from Xrandr 1.2 and higher
by Reinhard Tartler 13 Jun '16

13 Jun '16

Package: x2goagent When starting a new x2go session, the startup scripts modify the LD_LIBRARY_PATH of all applications to include /usr/lib/nx/X11/Xrandr. This replaces the system libXrandr with the NX/X2go provided one. Unfortunately, this breaks the xrandr utility: >> echo $LD_LIBRARY_PATH /usr/lib/nx/X11/Xrandr:/usr/lib/nx/X11/Xinerama:/usr/lib/nx/X11 >> xrandr xrandr: symbol lookup error: xrandr: undefined symbol: XRRGetScreenSizeRange zsh: exit 127 xrandr -- regards, Reinhard

Bug#838: control-alt-arrow keys
by Robert Dinse 24 Feb '16

24 Feb '16

Package: x2goagent I am using Ubuntu 14.10 with Mate Desktop with multiple work spaces. If I use Remmina with NX plugin, the control-alt-right/left arrow keys work to switch work spaces even when I'm up on a remote desktop. With X2Go, it usually doesn't work, except if I use control-alt-M to minimize the session then restore it, the keys will usually work thereafter. Remmina has a way to toggle this behavior, a little pull down at the top with a keyboard symbol. If it's down, the control-alt-arrows go to the end application allowing me to switch work spaces on the remote desktop, and if it's up they go to the local desktop. It would be nice if x2go had a similar facility but if not it would be better for that key sequence to always act locally since I can switch work spaces remotely by using the mouse but can not locally because the switcher is hidden by the remote desktop x2go is displaying. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Bug#847: Cleanly Terminating a Fullscreen Shadow Session Locally doesn't Work on MS Windows
by Stefan Baur 24 Feb '16

24 Feb '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 package: nxagent When trying to terminate a shadow session running in fullscreen mode on a MS Windows client, Alt-Tab gets passed to MS Windows, so one can reach the X2GoClient control buttons (folder sharing, pause, terminate), but clicking pause or terminate doesn't do anything.

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.
