Bug#276: qt/kde applications does not work as root.
by Pascal d'Hermilly 27 Mar '15

27 Mar '15

Package: x2goclient Version: 4.0.1.0 When I start qt/kde applications on the x2go server via the x2goclient, I get a grey application and a lot of error messages in the konsole. A workaround seems to be to change the graphicssystem to native instead of raster. However raster is the default in Kubuntu and it doesnt work when running things as root or through sudo. administrator@desktops-x2go:~$ sudo dolphin --graphicssystem raster X Error: BadDrawable (invalid Pixmap or Window parameter) 9 Major opcode: 62 (X_CopyArea) Resource id: 0x420007d X Error: BadDrawable (invalid Pixmap or Window parameter) 9 Major opcode: 62 (X_CopyArea) Resource id: 0x420007d X Error: BadDrawable (invalid Pixmap or Window parameter) 9 Major opcode: 62 (X_CopyArea) Resource id: 0x420007d X Error: BadDrawable (invalid Pixmap or Window parameter) 9 Major opcode: 62 (X_CopyArea) Resource id: 0x420007d X Error: BadPixmap (invalid Pixmap parameter) 4 Major opcode: 54 (X_FreePixmap) Resource id: 0x420007d X Error: BadShmSeg (invalid shared segment parameter) 128 Extension: 129 (MIT-SHM) Minor opcode: 2 (X_ShmDetach) Resource id: 0x420007c administrator@desktops-x2go:~$ sudo dolphin --graphicssystem native this works fine. Also gtk applications such as gimp works fine as root. This is quite a problem when you want to add/remove users and do other administrative things in KDE.

Failure negotiating the session in stage '7'
by Herbst, Sebastian 25 Mar '15

25 Mar '15

HI all, thank you for your work on x2go. It is a great tool. Unfortunately there is one single server. I can't connect to. It is installed just like another one (same packages different hardware), that is working, so it surely's got all necessary packages. XForwarding over ssh is working. As my other machines work well with each other, I am positive that this is an issue on the server. I tried to debug this, by increasing the log level on the server, but nothing suspicious showed up. The only hint is the client output: "Error: Failure negotiating the session in stage '7'. Error: Wrong version or invalid session authentication cookie." However none of the hints I googled worked for me. Also in IRC nobody was able to help me. I don't how to proceed. So I figured you could perhaps help me narrow down the problem. It is there any documentation describing the interaction of the server parts? If this is the wrong list to ask, please excuse me. Regards Sebastian Herbst

Bug#774: please set DESKTOP_SESSION and XDG_CURRENT_DESKTOP like local sessions
by Ryan Tandy 20 Mar '15

20 Mar '15

Package: x2goserver Version: 4.1.0.0-0~1215~ubuntu14.04.1 Severity: wishlist Hi, In Ubuntu before 15.04, and Debian jessie, the DESKTOP_SESSION for GNOME Flashback is actually "gnome-fallback". In particular, this name is found in /etc/upstart-xsessions while "gnome-flashback" is not, which prevents Upstart user sessions from being enabled. ("gnome-session --session=gnome-flashback is still the correct command, though.) Furthermore, recent (Ubuntu >= 13.10, Debian jessie) login managers also export XDG_CURRENT_DESKTOP using the value of the DesktopNames field from the session file. This variable is starting to gain wide use by applications that care about the desktop environment they run under. I can write a patch that adds all this information to x2goruncommand in the existing format. However it occurs to me that it might make more sense to parse the files in /usr/share/xsessions and use the information directly instead of duplicating it. Please let me know which you'd prefer to see. -- Ryan Tandy - Programmer/Analyst rtandy(a)sd63.bc.ca School District 63 (Saanich) +1 250 652 7385

Libdebug shows nothing...:( -------- Původní zpráva -------- Od: Mihai Moldovan Datum: 21.2.2015 Předmět: Re: [X2Go-Dev] Bug#788: Bug#788: Pyhoca-Gui freezes when connection to desktop Hi Sorry for the delay. I've noticed your message the first time around, but given that gevent is recent enough, I didn't have any additional information. I can only suggest to start pyhoca-gui with the additional parameters --debug and --libdebug to see what is going on (if anything.) Disclaimer: I have practically no idea of python in general and X2Go's python code (including pyhoca*) specifically, Mike is probably the best person to help with that.

Bug#798: Fwd: Bugs report using ssh proxy with x2goplugin
by nicolas husson 10 Mar '15

10 Mar '15

To: submit(a)bugs.x2go.org From: nicko466(a)gmail.com Subject: can't use ssh proxy with x2goplugin Package: x2goclient Version: 4.0.3.1 When I'm trying to use the ssh proxy configuration in session file with x2goplugin it seems its not working. Indeed, if you look at the session file in "~/.x2goclient/sessions" which contains all the configuration of the session of x2goclient application you will see all the descriptions of each session. Which looks like this for each session: [20150220100323537] speed=2 pack=16m-jpeg quality=3 fstunnel=true export="/home/user/Bureau/MountDistantX2goPc:1;" iconvto=UTF-8 iconvfrom=ISO8859-1 useiconv=false fullscreen=false multidisp=false display=1 maxdim=false rdpclient=rdesktop directrdpsettings= width=800 height=600 dpi=96 setdpi=true xinerama=false clipboard=both usekbd=true type=auto sound=true soundsystem=pulse startsoundsystem=true soundtunnel=true defsndport=true sndport=4713 print=true name=username icon=:icons/128x128/x2gosession.png host=localhost user=userTest key= rdpport=3389 sshport=2222 autologin=false krblogin=false krbdelegation=false directrdp=false rootless=false published=false applications=WWWBROWSER, MAILCLIENT, OFFICE, TERMINAL command=SHADOW rdpoptions= rdpserver= xdmcpserver=localhost *usesshproxy=true* *sshproxytype=SSH* *sshproxyuser=usernameProxy* *sshproxykeyfile=* *sshproxyhost=123.452.111.124* *sshproxyport=22* *sshproxysamepass=false* *sshproxysameuser=false* *sshproxyautologin=true* *sshproxykrblogin=false* The part which interest me is the bold part. Indeed, it works when i'm using this conf file with x2go client. And when i'm using x2goplugin with this configuration it doesn't work. I take a look at the network traffic and it seems that x2goplugin doesn't look at the bold part (the ssh proxy). This is why I think that x2goplugin doesn't work with ssh proxy.

[git repositories] New branching concept
by Mihai Moldovan 09 Mar '15

09 Mar '15

Hi, This information targets all users with commit privileges to the official x2go repositories. Coming up soon™, new branching policies will be in effect. TLDR: DO: - create feature branches as "feature/<name>" - comment on need for "bugfix/<name>" branches - rebase your feature branches against master - only send "pull requests" for your feature branches once they have been rebased - NO MERGE CONFLICTS! - send emails to git-admin(a)x2go.org for branch deletion, renaming or "pull requests" DON'T: - be afraid to make mistakes on your feature branches or ask - try to rebase or merge other branches into master (will be rejected) - try to delete branches (will be rejected) - try to rename branches (might leave you with a mess) Details: Historically, non-fast-forward (created by the rebase operation) and merge commits have been rejected on all branches. These restrictions will be loosened to allow committers more control over their branches and ease merging of pull requests. The new policies will allow non-fast-forwards and merge commits within feature branches. That means developers will be able to to rebase and merge other branches. In fact, committers will be required to rebase their feature branch against the master branch for pull requests. Requests with conflicts will not be merged. This new concept will not affect master and release/* branches. On these branches, rebases and merges will still be rejected. Feature branches should follow the template feature/<name> to ensure consistency with our current release/<version> release branches. The current branches will be accordingly renamed once the new policy is in effect. If you do see any benefit of a new branch type, like bugfix/<name> or bugfix/<version>, please let me know. We can then discuss policies regarding those. For now, please refrain from creating these branches. Please send an email to git-admin(a)x2go.org to initiate a pull request. Don't forget to mention the branch you want to have merged into master. The admin will review and then either merge or deny your request. This said, please try to refrain from uselessly rebasing your branches to delete mistakes or squish commits together, unless it really makes sense. Don't be afraid to be human. Commit early, commit often. Don't forge the history. For renaming and deletion of branches, please also contact git-admin(a)x2go.org. Creation is possible without former notification of git-admin, but please make sure to follow naming conventions as outlined in this email. The new policies will be effective once implemented and Mike#1 finishes the outstanding release of all components. Best Mihai

"features/cleanup" (and "bugfix/osx") branch in x2goclient.git
by Mihai Moldovan 06 Mar '15

06 Mar '15

Hi all For the last couple of weeks, I've been working on the OS X side of X2Go Client, as some of you may or may not have noticed. Part of that work was a restructuring of the x2goclient.git repository. I started forking master to features/cleanup, gradually moved files around into new sub-directories and adapted all files affected by these moves. Additionally, macbuild.sh has been severely improved. It now supports multiple environment variables. A help message can be queried by (./)macbuild.sh -h or --help from any OS and will not be included here. x2goclient is now built in the client_build sub-directory to not pollute the main directory or overwrite the Makefile. List of changes: - moved .cpp/.h/.ui sources to src/ - moved png, svg and icons to res/ - moved all translation files to res/i18n/ - moved OS X build related files to res/macbuild/ - removed config_mac.sh (macbuild.sh supersedes it) - aforementioned macbuild.sh changes - change "legacy" resource URL's (":/icons/...", ":/png/...", ":/svg/...") to their ":/img/..." counterparts - added transparent wrapper to x2goutils.cpp for wrapping "legacy" resource URL's to their new locations for backwards-compatibility with old session config files - fixed some compiler warnings (mostly unused variables/parameters) - fixed *some* QMessageBox::<function> calls. There still are a lot of plain incorrect calls left. - typo, grammar and outdated information fixes A visual representation of these changes can be seen when comparing http://code.x2go.org/gitweb?p=x2goclient.git;a=tree and http://code.x2go.org/gitweb?p=x2goclient.git;a=tree;h=refs/heads/feature/cl… The bugfix/osx branch is currently equivalent to features/cleanup. Subsequent OS X fixes will be published on bugfix/osx. features/cleanup is scheduled to be merged into master (and thus become the X2Go Client 4.0.4.0 base) either shortly after this report, or after the upcoming X2Go Developer Meeting at the beginning of March. What is YOUR opinion? Best, Mihai

Bug#789: Kerberos 5 auth. reset putty sessions list
by Jozsef Kozo 05 Mar '15

05 Mar '15

Package: X2Go Client Version: 4.0.3.1( Qt-4.8.6 ) OS: Windows 8.1 Enterprise x64 Dear Dev. Team, I switched on "Kerberos 5 (GSSAPI) authentication" on X2Go client and all my saved Putty sessions are gone. So Saved session list is empty. I tried to recover from registry but can't. You can reproduce like this: 1. Save a session to Putty 2. Set Kerberos 5 (GSSAPI) authentication 3. Connect to X2Go server Any idea how can i recover my list? Best, Jozsef Kozo
