x2go on RHEL7/CentOS7
by Paul Raines 05 Aug '15

05 Aug '15

We have been using x2go fairly successful on CentOS6 machines now for a while. We are investigating upgrading to CentOS7 and I am now looking at the x2go situation We get our x2go RPMS from EPEL x2goagent-3.5.0.31-1.el7.x86_64 x2goclient-4.0.3.1-1.el7.x86_64 x2goserver-4.0.1.19-3.el7.x86_64 x2godesktopsharing-3.1.1.1-1.el7.x86_64 So far we have not discovered 1) doesn't work at all with GNOME desktop giving the "Oops" screen. Web search seems to imply this is a known issue with GNOME3 with no real solution though I am suprised this is not mentioned in the X2Go wiki FAQ. I hate GNOME3 anyway so can live without it for X2Go 2) works partially with the KDE desktop. There is the kscreen issue that is mentioned in the FAQ. Really unusable unless one does disable kscreen. Need to investigate further what consequences that has on normal logins. 3) installed MATE from EPEL. On first login it looks and works great but when you "Logout ..." to terminate the session it just hangs on a blank background. If you "suspend" the session via force closing the window and then try to reconnect it fails or just takes you right back to the blank background. One can force terminate the session with x2goterminate-session to clear it out and then get a clean login again, but I don't really want my users having to go though this. So my question is really about the MATE issue which I would prefer to use. Anyone have any clues as to what might be going on or a fix? --------------------------------------------------------------- Paul Raines http://help.nmr.mgh.harvard.edu MGH/MIT/HMS Athinoula A.

by Andrea Argentini 31 Jul '15

31 Jul '15

Hi, Untill yesterday I used a X2go client 4.03 on windows 8.1 and it worked well. This morning X2go client starts (I mean that I see the program on the windows program bar) but I cant show it on the desktop. I m not able to use it any more. I installed the last version of the client , but I have the same problem. I have read in other post to output a log of the command vcxsrv.exe -logverbose 3 following I included the log output. Can you help me to fix this problem?

Install problem
by Hosseinzadeh, Jafar 31 Jul '15

31 Jul '15

Hello, I have been using an older version x2go client for a while now and I like it. This morning I tried to install the new version. I uninstalled the old version then tried to install version 4.0.4 (32-bit version) on a 64-bit Windows 7. The install completes however, there are no sign of installed x2go. I tied to install the older version (4.0.3) but the same results. I have turned off the anti virus and run the install as administrator. Any suggestions. Regards, --jh

Bug#909: X2Go issue (in src:x2goclient) has been marked as closed
by X2Go Release Manager 28 Jul '15

28 Jul '15

close #909 thanks Hello, we are very hopeful that X2Go issue #909 reported by you has been resolved in the new release (4.0.5.0) of the X2Go source project »src:x2goclient«. You can view the complete changelog entry of src:x2goclient (4.0.5.0) below, and you can use the following link to view all the code changes between this and the last release of src:x2goclient. http://code.x2go.org/gitweb?p=x2goclient.git;a=commitdiff;h=4caef96a30c62c2… If you feel that the issue has not been resolved satisfyingly, feel free to reopen this bug report or submit a follow-up report with further observations described based on the new released version of src:x2goclient. Thanks a lot for contributing to X2Go!!! light+love X2Go Git Admin (on behalf of the sender of this mail) --- X2Go Component: src:x2goclient Version: 4.0.5.0-0x2go1 Status: RELEASE Date: Tue, 28 Jul 2015 04:48:20 +0200 Fixes: 696 882 901 909 911 Changes: x2goclient (4.0.5.0-0x2go1) RELEASED; urgency=low . [ Mihai Moldovan ] * New upstream release (4.0.5.0): - INSTALL: add more verbose instructions on how to build X2Go Client and friends. - onmainwindow.{cpp,h}: rename slotScDaemonOut() and slotScDaemonError() to slotScDaemonStdOut() and slotScDaemonStdErr(). I will need slotScDaemonError() later and the previous names were a bit of a misnomer. - x2goutils.{cpp,h}: add new show_RichText_Generic_MsgBox() main function designed to replace the show_RichText_WarningMsgBox() function. - x2goutils.{cpp,h}: make show_RichText_WarningMsgBox() use show_RichText_Generic_MsgBox (). - x2goutils.{cpp,h}: new show_RichText_ErrorMsgBox() function as a wrapper for show_RichText_Generic_MsgBox() with a critical icon. - onmainwindow.{cpp,h}: properly handle scdaemon errors with a message box and close the client. - onmainwindow.cpp: manipulate PATH and append /usr/lib/gnupg2/ to it when starting scdaemon. Fixes: #882. - x2goutils.h: add QMessageBox include, fixed compile error. - onmainwindow.cpp: fix typos leading to compile errors. - onmainwindow.cpp: add blocks to switch cases to fix a compile error. Also correctly append to informative_text on one occasion, instead of overwriting it. - x2goutils.cpp: correct typo to fix compile errors. - onmainwindow.cpp: drop a redundant variable and fix empty env check. - onmainwindow.cpp: add more newlines to scdaemon error output. Use trayQuit() method to really quit the client. - onmainwindow.cpp: add debugging output for new scdaemon PATH value. - onmainwindow.cpp: split up PATH value as printed in the error message box by a newline every 100 characters. Makes it look less ugly and fixes truncation issues. - sshprocess.cpp: export PATH variable when running commands. Otherwise, only the first one will respect the new PATH value. - sshprocess.cpp: wrap SSH command prelude and conclusion in double quotes. - sshprocess.cpp: wrap all remote commands with "bash" instead of the unspecific "sh". - onmainwindow.cpp: try to escape shell quotes correctly when using Kerberos/GSSApi when running the xmodmap keyboard sync command on OS X. - onmainwindow.cpp: also escape other shell quotes when using Kerberos/GSSApi. - onmainwindow.cpp: silence compiler warning by casting an int value to std::size_t. - onmainwindow.cpp: silence another compiler warning by not converting from string to int and back to string needlessly. Just use the string. No need for an OS X-specific variable anymore. - onmainwindow.cpp: fix compile error - use QString.toAscii () to get a valid C string representation for tr (). - onmainwindow.cpp: don't terminate if scdaemon exited with non-zero exit code. - sshprocess.cpp: don't use QProcess::start (QString). Qt is trying to be too smart and causes big trouble. Instead, use QProcess::start (QString, QStringList) and pass the arguments as a list. On Windows, Qt will automatically double quote the arguments and duplicate escaped double quotes or escape non-escaped double quotes. On UNIX-like platforms, each element of the list is passed as a unique argv element, so there's no need for quoting them (that's only a shell-internal thing to group arguments.) - sshprocess.cpp: add a bit more debugging - also print out the unmodified raw output of SSH commands. - onmainwindow.cpp: remove now-bogus double quote escaping. - sshmasterconnection.cpp: port QProcess::start () change. - sshprocess.cpp: whitespace/prettify only and a compile fix. - x2goclient.pro: reinstate old lrelease "search" behavior if qtPrepareTool() is not available. This should only happen on EPEL 6, which ships a broken Qt4 version... - onmainwindow.cpp: only set multidisplay mode for non-rootless sessions. - {ui/xsettingsui.ui,xsettingswidget.cpp}: add new "whole display" option for external X server configuration. Part of #883. - onmainwindow.cpp: rename "optionsmd" setting to "optionswholedisplay", which is more clear. - xsettingswidget.cpp: fix compile error: settings -> setting. - sessionmanagedialog.cpp: enable some debugging and make selected sessions configureable or deletable. Fixes: #909. . [ Mike Gabriel ] * debian/control: + Add alternative D for nxproxy: qvd-nxproxy. Allows parallel installation of X2Go Client and the TheQVD client (perl-qvd-client). .

(Fixes: #696) - Linux: Fix desktop session icons (.desktop files) failing due to missing space between "x2goclient" and its 1st argument (e.g. "--session") (Fixes: #911) .

Greyed out buttons in Session Management.
by Paul Raines 24 Jul '15

24 Jul '15

Well, I just realized I have the same greyed out button issue on my X2GO client on my Windows box at home. So this has nothing to do with domains or profile migration. Basically in Session Management all buttons on the right are greyed out except "New Session" no matter what session I select on the left.
