[ Mike Gabriel ] * Update 0320_nxagent_configurable-keystrokes.full.patch. Fix patch header referring to keystrokes.cfg (plural), not keystroke.cfg. * Allow sysadmins to manipulate nxagent's / x2goagent's rgb file by placing it into /etc/nxagent or /etc/x2go. * Provide support for separate .keyboard files for nxagent/x2goagent. * Modify 0101_nxagent_set-rgb-path.full.patch. Allow configurable rgb files. * Extend 0999_nxagent_unbrand-nxagent-brand-x2goagent.full.patch. Let rgb file shipped with x2goagent supersede rgb file shipped with nxagent. FIXME: a better approach would be to decide at runtime if to use /etc/x2go/rgb or /etc/nxagent/rgb. * Extend 0999_nxagent_unbrand-nxagent-brand-x2goagent.full.patch. Allow separate .keyboard files for x2goagent and nxagent. * Update 0600_nx-X11+nxcompext+nxcompshad_unique-libnames.full.patch. Don't patch files that get removed during code reduction. * Add 0991_fix-hr-typos.full+lite.patch and 991_fix-hr-typos.full.patch.

support for all-numerical user ids
by ENRICO BERTOCCHI 12 Mar '15

12 Mar '15

Dear sirs, I installed x2goserver on a debian wheezy machine dedicated to teaching activities. The usernames retrieved from our university LDAP server (on which I have no authority) are allowed to be fully numerical, and most students have fully numerical uids. In order to have a working x2goserver, I changed the regex expression in the sub sanitizer, "x2gosid" section, of /usr/lib/x2go/x2goutils.pm (line 46) /usr/lib/x2go/x2gosqlitewrapper.pl (line 67) from if ($string =~ /^([a-zA-Z\_][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-[...etc...] to if ($string =~ /^([a-zA-Z\_0-9][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-[...etc...] Being a mechanical engineer with limited developing experience and no perl knowledge, I can't state if such a change has undesired side effects. Could you check if such change would be acceptable? The only justification of our LDAP managers is probably that the POSIX standard allows usernames beginning with numbers (see e.g. discussion http://serverfault.com/questions/73084/what-characters-should-i-use-or-not-… ) Thanking for the kind attention -- Enrico Bertocchi

Bug#797: xinamera extension is broken after update
by Fernando Pedemonte 12 Mar '15

12 Mar '15

Hi all, I was having this problem also, and after some debugging I was able to trace the problem to a function in the file onmainwindow.cpp at the x2goclient package. Enabling the debug on the client I saw at the step of creating the xinerama.conf file inside $HOME/.x2go/xxxxxx/ directory the following: x2go-DEBUG-../sshmasterconnection.cpp:1469> executing remote: "sh -c 'echo X2GODATABEGIN:38317d7e-972d-417f-9745-ef9cb09d7e35; PATH=/usr/local/bin:/usr/bin:/bin export DISPLAY=:50;printf '1600 0 1600 900\\n0 0 1600 900' > $HOME/.x2go/C-fpedemonte-50-1426195616_stDXFCE_dp24/xinerama.conf; echo X2GODATAEND:38317d7e-972d-417f-9745-ef9cb09d7e35;'" As you can see, the "\n" is not escaped correctly. What I did was to modify the following line of code inside onmainwindow.cpp line 10212 QString cmd="export DISPLAY=:"+resumingSession.display+";printf '"+screens.join("\\\\n")+"' > $HOME/.x2go/C-"+ resumingSession.sessionId+"/xinerama.conf"; To: QString cmd="export DISPLAY=:"+resumingSession.display+";printf \""+screens.join("\\n")+"\" > $HOME/.x2go/C-"+ resumingSession.sessionId+"/xinerama.conf"; After this modification, xinerama is working again. Take note that I also replaced the single quote by double quote and escaped them. Without this modification the printf command was failing to create the xinerama.conf file.

Bug#804: slot argument mismatch in ONMainWindow::slotTunnelOk causes hang during connect
by Will Wagner 12 Mar '15

12 Mar '15

Package: x2goclient Version: 4.0.3.2 When trying to connect to certain servers I get 'Object::connect: No such slot ONMainWindow::slotTunnelOk()' in the debugging output of X2Go Client for Windows 4.0.3.2. The application hangs without ever connecting. From looking at the code in ONMainWindow::slotTunnelOk() it has a check to see if winServersReady is true and if not it uses QTimer::singleShot to retry 100mS later. However the slot connection has an argument mismatch and so slotTunnelOk is never called again and this leads to the hang. The full debug output is: x2go-INFO-1> "Starting x2goclient..." x2go-WARNING-1> "Can't load translator: :/x2goclient_en_gb" x2go-WARNING-2> "Can't load translator: :/qt_en_GB" x2go-DEBUG-onmainwindow.cpp:1208> Removing apps from tray x2go-DEBUG-onmainwindow.cpp:1176> Plugging apps in tray. x2go-DEBUG-onmainwindow.cpp:9817> Getting Xorg settings. x2go-INFO-3> "Started x2goclient." x2go-DEBUG-onmainwindow.cpp:495> "$HOME=C:/Users/willw" x2go-DEBUG-onmainwindow.cpp:2123> Reading 4 sessions from config file. x2go-DEBUG-onmainwindow.cpp:9543> Starting win servers... x2go-DEBUG-onmainwindow.cpp:9895> "C:/Users/willw/.x2go/etc/sshd_config created." x2go-DEBUG-onmainwindow.cpp:9312> got localhost x2go-DEBUG-onmainwindow.cpp:9334> Port is free: 7022 x2go-DEBUG-onmainwindow.cpp:9951> Creating desktop: x2go_willw x2go-DEBUG-onmainwindow.cpp:1208> Removing apps from tray x2go-INFO-8> "Starting connection to server: 172.20.0.2:22" x2go-DEBUG-onmainwindow.cpp:2702> Start new ssh connection to server:"172.20.0.2":"22" krbLogin: false x2go-DEBUG-sshmasterconnection.cpp:202> starting ssh connection without kerberos authentication x2go-DEBUG-sshmasterconnection.cpp:206> SshMasterConnection, instance SshMasterConnection(0x15a8d58) created x2go-DEBUG-sshmasterconnection.cpp:442> SshMasterConnection, instance SshMasterConnection(0x15a8d58) entering thread x2go-DEBUG-sshmasterconnection.cpp:478> libSsh not inited yet, initting x2go-DEBUG-sshmasterconnection.cpp:522> setting SSH DIR to "C:/Users/willw/ssh" x2go-DEBUG-sshmasterconnection.cpp:789> cserverAuth x2go-DEBUG-sshmasterconnection.cpp:804> state: 1 x2go-DEBUG-sshmasterconnection.cpp:640> setting SSH DIR to "C:/Users/willw/ssh" x2go-DEBUG-sshmasterconnection.cpp:963> Password authentication x2go-DEBUG-sshmasterconnection.cpp:654> user auth OK x2go-DEBUG-onmainwindow.cpp:2797> SSH connection established. x2go-DEBUG-onmainwindow.cpp:3060> Continue normal x2go session x2go-DEBUG-sshprocess.cpp:189> executing remote command via SshProcess object (0): "export HOSTNAME && x2golistsessions" x2go-DEBUG-sshmasterconnection.cpp:1434> creating new channel x2go-DEBUG-sshmasterconnection.cpp:1438> new channel:0x37196b0 x2go-DEBUG-sshmasterconnection.cpp:1469> executing remote: "sh -c 'echo X2GODATABEGIN:819aa939-7479-4d86-bbeb-8c9e041031a8;

Bug#812: x2gogetapps should ignore NoDisplay=true desktop application entries
by Jason Alavaliant 11 Mar '15

11 Mar '15

Package: x2goserver Version: 4.0.1.19 Tags: patch Currently the x2gogetapps command prints out all .desktop application files irrespective of if they have the value NoDisplay=true set in the file or not. This results in the hosted applications list becoming filled with entries that weren't intended to be listed in an application menu normally. For example on my system I have; /usr/share/applications/kde4/okularApplication_comicbook.desktop /usr/share/applications/kde4/okularApplication_ooo.desktop /usr/share/applications/kde4/okularApplication_dvi.desktop /usr/share/applications/kde4/okularApplication_pdf.desktop /usr/share/applications/kde4/okularApplication_fax.desktop /usr/share/applications/kde4/okularApplication_plucker.desktop /usr/share/applications/kde4/okularApplication_fb.desktop /usr/share/applications/kde4/okularApplication_txt.desktop /usr/share/applications/kde4/okularApplication_ghostview.desktop /usr/share/applications/kde4/okularApplication_xps.desktop /usr/share/applications/kde4/okularApplication_kimgio.desktop /usr/share/applications/kde4/okular.desktop /usr/share/applications/kde4/okularApplication_mobi.desktop All of them except okular.desktop have NoDisplay=true set in the file, a normal desktop environment menu has one entry for okular shown since it doesn't list all of those other entries. The x2go application list currently has 13 entries for okular since it displays every single one of the entries. The attached patch updates the x2gogetapps command to check the file to see if NoDisplay=true is set and if so doesn't print out the contents of that file removing all the duplicates and other entries not intended to be listed in a normal application launch menu. Thanks Jason

Bug#814: Properly starting xubuntu (and others) session in Ubuntu
by Hrvoje Habjanić 10 Mar '15

10 Mar '15

Package: x2goserver-xsession Version: 4.0.1.19-0~1062~ubuntu14.04.1 Hi. It seems that ubuntu requires some additional stuff to be started, to successfully fork X virtual session. The most notable is calling of init script with "--user" argument. Scripts used by /etc/X11/Xsession do most of the stuff ok, and are used by GUI launchers (ie. lightdm). Unfortunately, it requires some additional environment variables to work properly. In most cases, it seems that DESKTOP_SESSION is the most important one. Following does script properly starts xubuntu session, and is the same as started from lightdm: -------[snip]------- PATH=$PATH:/sbin export DESKTOP_SESSION=xubuntu exec /etc/X11/Xsession 'env XAUTHORITY=/home/'$LOGNAME'/.Xauthority /usr/bin/xfce4-session' -------[snip]------- It is enough to put this somewhere on OS, and set it up as script to be started when session start via x2gosession GUI. List of possible values in "DESKTOP_SESSION" is available in /etc/upstart-xsessions. It would be nice if you could put this information somewhere on the wiki, so other users can use it to properly start session(s). Regards, H.
