Bug#362: Chromium/chrome still crash VcXsrv when used with X2Go (VcXsrv doesn't crash with Chromium/Chrome and plain X via SSH)
by Stefan Baur 06 Jun '14

06 Jun '14

Package: x2goclient Severity: wishlist Version: 4.0.1.2 Even with the newer Xserver that is included in x2goclient-4.0.1.2-pre02-setup, Chromium and Chrome still crash at random intervals. To be exact, they're not crashing themselves, they're crashing the Xserver. Pausing and resuming a session lets you continue where you stopped, yet, this is an instability that users won't put up with since they quit Windows 98/Millennium for good. It's only when X2Go is involved that these crashes occur - if you export the display with ssh (from PuTTY) instead of using x2goclient.exe, Chromium and Chrome behave well. This is not a showstopper for me (my customers are using Iceweasel so far), but it is an issue where I had hoped to see some improvement with the new Xserver.

Bug#42: GNOME3 desktop (in non-fullscreen mode) does XRandR resizing of the desktop session window
by Mike Gabriel 16 May '14

16 May '14

Package: x2gognomebindings Severity: important Version: 2.0.1.6 When a GNOME3 desktop is opened via X2Go in non-fullscreen mode the GNOME3 xrandr / monitor settings code does some awful resizing of the desktop session window. Reproduce (GNOME3, also an issue with Unity): o you need a client-side display greater than 1024x768 o set desktop size to 1024x768 in x2goclient session profile settings o set desktop session to GNOME on a Debian wheezy server o launch session Compare to KDE4: o you need a client-side display greater than 1024x768 o set desktop size to 1024x768 in x2goclient session profile settings o set desktop session to KDE on a Debian wheezy server o launch session What you see: o with KDE4 the desktop session window will have the expected size o with GNOME3 the window appears in the expected size and then gets resized from inside the starting up GNOME3 session o in my case: GNOME3 tries to resize to 1920x1200 pixel. The windows gets adapted to the greatest size possible on my client display (i.e. the window maximizes) o However, the desktop shell inside the window does not adapt to the window size o I can manually resize the window afterwards via the client-side window manager (play with your mouse on the window borders...) o Still, the desktop shell inside does not adapt its size This might well be a GNOME3 bug (detection of X server resize events), but it normally won't cause problems on physical hardware. So, the X2Go team may have to discover a GNOME3 patch for this problem.

Bug#349: Tag: patch
by marcoandredinis＠gmail.com 31 Mar '14

31 Mar '14

Package: x2goclient Version: 4.0.1.1 This email was sent to x2go-dev mailling list, but since it also refers a Bug, I am also filling a bug report Hi I'm developing a program that will use X2Go software. I dont want users to notice they are using any other program besides my own. I have two problems right now: A) X2GoClient Using SHADOW mode with "--hide" does not work. The interface waits for selection of Display (usually ":0") and, since there's no input from user (there's no window) the program does not show anything. There are possible ways of fixing/improving this situation: -allow user to set the default display on sessions' file -create one flag and run program like these: "x2goclient --hide --sessionid=xxx --select-first-display" Anyway, i modified the code of x2goclient/onmainwindow.cpp and added these lines: l4348:..if( shadowSession ) l4349:....slotShadowSess(); Compiled the program, and now i can run "./x2goclient --hide --sessionid=xxx" and the window will show up. This is NOT a fix, this is a nasty workaround. It wontn show the list even when the "hide" flag is not present. B) X2GoDesktopSharing Just the icon on SystemTray. If we could pass a flag like "--no-icon" would be great I could do these simple changes on my own, but i rather see this changes on the official code. Thanks, Marco Dinis

libssh changes. Information for package maintainers
by Oleksandr Shneyder 18 Mar '14

18 Mar '14

Hello, as you know, I made some changes in X2Go Client code. Especially important is that X2Go Client do not open for every reverse tunnel a new ssh connection any more. To make it possible, I made some improvements in libssh. The patch is already accepted by libssh team and Mike will take care about linux packages. The libssh patch for reverse connections is here: http://code.x2go.org/releases/libssh/libssh-0.5.x-accept-forward.patch I have also found another one issue with libssh, however I have not yet an answer from libssh team if they will accept this patch. It is very important for Mac Client to use libssh with this patch. In other case you can expect the poor performance of X2Go Client. You can find a patch here: http://code.x2go.org/releases/libssh/libssh-0.5.x-unblock.patch To be able build current X2Go Client code on Mac or Windows you also need a libssh with this two patches. @Michael DePaulo. Please apply this two patches on your libssh source tree. If you don't want to build libssh by yourself, you can use binaries built by me: http://code.x2go.org/releases/libssh/libssh-0.5.5.zip @Clemens Lang. If you build libssh using brew, you can do next: - uninstall old version of libssh $brew uninstall libssh $cd $(brew --prefix) $brew update - get available libssh vesrions $brew versions libssh - switch to libssh-0.5.5 $git checkout 91e973b Library/Formula/libssh.rb - edit formula $brew edit libssh add libssh patches before def install: def patches [ "http://code.x2go.org/releases/libssh/libssh-0.5.x-accept-forward.patch", "http://code.x2go.org/releases/libssh/libssh-0.5.x-unblock.patch" ] end after that you can build libssh as usual: $brew install libssh regards Alex -- ---------------------------------------------------- Oleksandr Shneyder | Email: o.shneyder(a)phoca-gmbh.de phoca GmbH | Tel. : 0911 - 14870374 0 Bräuhausgasse 9 | Fax. : 0911 - 14870374 9 D-82205 Gilching | Mobil: 0163 - 49 64 461 Geschäftsführung: Dipl.-Inf.

Bug#229: x2goclient for windows unable to use https broker-urls
by Anders Bruun Olsen 27 Feb '14

27 Feb '14

Package: x2goclient Version: 4.0.1.0-pre2 and 4.0.0.3 Platform: Windows I can login to our broker with x2goclient just fine on OSX and Linux, using our externally available https-server. On Windows however, it just fails authentication when using our https-server. It works fine when the broker-url is an http-address. I do not have a build-system for Windows at hand, so I am unable to test newest git revision on Windows. -- Anders Bruun Olsen It-ansvarlig Det Danske Sprog- og Litteraturselskab (Society for Danish Language and Literature)

x2goDebug
by Michael DePaulo 03 Feb '14

03 Feb '14

Is there a way to view the "x2goDebug" statements on win32? Honestly, I'm not even sure where the function is defined. I'm thinking I might need to load up a full IDE (rather than a text editor) to do that.

Bug#421: X2goclient on Windows: sshd.exe does not start.
by jordi＠amospalla.es 30 Jan '14

30 Jan '14

Package: X2goclient Version: 4.0.1.3 Client host: windows xp Server host: debian wheezy - When enabling support for printer sharing, or sharing a folder, sshd.exe does not start, and so these features are not available. - If I launch manually sshd (from what I understand x2goclient launches from reading source code) sshd.exe launches and stays until I kill it: "C:\Program Files\x2goclient\sshd.exe" -D -p 7022 -f "/cygdrive/c/Documents and Settings/User/.x2go/etc/sshd_config" -h "/cygdrive/c/Documents and Settings/User/.x2go/etc/ssh_host_dsa_key" - Every time I try to share a folder with the session running, I can see on the process manager ssh-keygen is launched. - Server host shows the remote folders as mounted on /proc/mounts, so accessing them makes a process hang. - Firewall is disabled on client host.

Package: nx-libs Version: 3.5.0.22 Tags: patch The attached patch fixes more -Werror=format-security errors. Interestingly, most of the errors only showed up on our arm builds. No idea why. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA/CoRA Division FAX: 303-415-9702 3380 Mitchell Lane orion(a)cora.nwra.com Boulder, CO 80301 http://www.cora.nwra.com

Bug#422: Windows PulseAudio 3.0 and later fail to start due to missing cookie
by Michael DePaulo 30 Jan '14

30 Jan '14

Package: x2goclient Version: 4.0.1.3 X2Go Client 4.0.1.3 for for Windows is bundled with PulseAudio 1.1. If you replace 1.1 with 3.0 or later (2.0 was not tested), the .pulse-cookie file is not created and therefore pulseaudio.exe either fails to start or repeatedly restarts. The bottom line is that sound will not work in Windows X2go Client with these newer versions of PulseAudio. The simple workaround is to run X2Go Client with PulseAudio 1.1 once and then exit x2goclient. The cookie will be present even after x2goclient is closed. Newer versions of PulseAudio can then use that cookie. These are my full test results for what files are generated with different versions of PulseAudio. They were tested on windows 7 32-bit SP1 Professional (with all important and recommended windows updates installed.) "mothership-7-32" is my test VM's hostname. Note that I tested PulseAudio 1.1 (and 1 or 2 newer versions) under Windows 8.1 64-bit Professional (with all important and recommended windows updates installed) and the results were the same. 1.1: Under C:\Users\mike\.x2go\pulse\ : .pulse-cookie .esd_auth .pulse\ .pulse\mothership-7-32-runtime\ tmp.Hp2820\ tmp.Hp2820\config.pa 3.0 Under C:\Users\mike\.x2go\pulse\ : .pulse\ .pulse\mothership-7-32-runtime\ tmp.Hp1572 tmp.Hp1572\config.pa (Pulseaudio.exe does not appear to be running at all, but maybe what happened under 4.99.2 is happening.) 4.0: Under C:\Users\mike\.x2go\pulse\ : .pulse\ .pulse\mothership-7-32-runtime\ .pulse\mothership-7-32-runtime\pid tmp.Hp2656 tmp.Hp2656\config.pa Also, windows complains that "pulseaudio.exe has stopped working". And it does so repeatedly,.This suggests that x2goclient.exe keeps on trying to restart pulseaudio.exe 4.99.2: Under C:\Users\mike\.x2go\pulse\ : .pulse\ .pulse\mothership-7-32-runtime\ .pulse\mothership-7-32-runtime\pid (keeps on being created and then disappearing because pulseaudio.exe keeps stopping and starting) tmp.Hp3716 tmp.Hp3716\config.pa -Mike#2

Bug#420: Fix password connection with libssh 0.6.0
by Orion Poplawski 29 Jan '14

29 Jan '14

Package: x2goclient Version: 4.0.1.3 Tags: patch Starting with libssh 0.6.0, ssh_userauth_list() no longer automatically calls ssh_userauth_none() if needed (auth_methods == 0) to populate the list of methods available. This patch calls it explicitly. An alternative would be to simply try authenticating. Without this, attempts to connect with a password fails with an empty "Authentication failed" error window. -- 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
