This could be red!?) With this arrangement we can reuse much of the stuff already there and still make the applet more secure (as it makes the user more aware of what she/he is doing). Any further ideas? Feedback? Criticism? If not, do you want to start on any of the above aspects? I will open up a branch in Git and I will commit anything you come up with. Currently, I feel more like a reviewer and proof-reader but that might change was you send your first drafts. Is that ok with you?

Thanks.
the /usr/bin/x2gostartagent script does not sufficiently specify the
location of $XAUTHORITY file for the xauth command, while the
command line for starting x2goagent refers to a specific location
$HOME/.Xauthority.
I have modified your patch slightly, could you test my patch if that
works for you???

Should we want -xauth parameter for x2goagent (xserver), wouldn't it be
consistent to add the same for xauth commands? (Patch attached.)
P.S. It works for me with the extra patch and also w/o it.

This seems to be a compilation-time configure option GROUP_NAME_MAX_LENGTH... On Debian (I looked at Knoppix actually), the limit is relaxed a bit: 32 chars.

[X2Go-Dev] Font colour in x2goclient in case of dark system theme
Hello,
the x2goclient has hardcoded light appearance for the various widgets
(main window, session list, login window, progress of logging in),
which does not work well with dark system theme: the white font is not
distinquishable from the background.
I have checked the Qt documentation and there seems to be more ways
on how to accomplish that. So far, I have used three various methods:
labelname-setStyleSheet(QLabel { color : black; });
or
cpal.setColor ( QPalette::Text, Qt::black);
or
QString fonttemplate=(font color='black'%1/font);
nameLabel-setTextFormat ( Qt::RichText );
nameLabel-setText ( fonttemplate.arg( text ) );
which kind of works, though it requires to be written repeatedly
throughout the code (sessionbutton.cpp, onmainwindow.cpp,
onmainwindow_part4.cpp) for individual widgets and so far I am not able
to use a single approach for all widget types (QLabel, QMenu,
QPushButton, etc.). The first method seems to be the most general and
simplest, however.
Is there a way to set application-wide font colour for anything
that appears in the widgets, but not in app menu and other windows
(Settings, Session Settings, etc.), because these are styled with the
system-wide dark theme?
Where in the code?
P.S. Sorry for possibly stupid question, but since I am not a coder, it
is rather a trial error approach and a lot of googling...
Regards,
Milan

Hello,
I get Segmentation fault when I right-click on x2godesktopsharing
icon in the system tray and choose Activate Desktop Sharing. (Arch
Linux.)
The segfault was due to non-existent x2godesktopsharing group in the
system.
This involves two matters:
x Arch Linux does not allow for group names longer then 16 characters.
x x2godesktopsharing should check for existence of the group and quit
nicely otherwise.
Since I am not a coder, I was able to solve only the first issue -
patches are attached. (The debian postinst script should probably
handle the original group name as well - e.g. move the members to the
new group.)
It would be nice if it is accepted upstream, since a similar limitation
might also exist on other *nix systems.

Milan

Unless I am doing something wrong, fakeroot make DESTDIR=/some/path install leads to installation of the libsbinaries to usr/X11R6 and not all components required for x2goagent (incl. x2goagent wrapper itself) are installed anyway. To work around that, I am using install command for all the libs and binaries with the use of the precompiled DEB packages as a template. A second point: in Arch linux, the X2Go packages (incl. nx-libs) are in AUR (user-contributed repository), which does not support so called split packages (i.e. I cannot compile the nx-libs tar ball and create several packages in one go like you do in Debian) [1]. So at the moment, the semi-automatic build process has to download and compile major part of nx-libs repeatedly for each of the dependency (nxcomp: requires nx-x11; nxagent: requires nx-x11, nxcomp, nxcompext, ..., nx-x11; etc...). It works, nonetheless it is slow and inefficient. How difficult would it be to have the Makefiles modified to search for the dependency in the system (/usr/lib/nx/X11...) instead in the source tree? [1] It actually is possible to create split packages with a little hack, but then it is not possible to automatically install the split packages as dependencies of others - AUR (and tools supporting automated compilation installation from AUR like yaourt) cannot search in the list of split packages.

[X2Go-Dev] [PATCH] x2goserver.git/bin/x2goumount-session
Hello,
find attached the following patches for bin/x2goumount-session script:
0001: the DESKTOP file for shares of /cygwin/C:/some/path got not
removed due to redundant /cygwin/ string.
0002: the $HOME/media or $HOME/media/${USER}_media symlink got not
removed after session end.
0003: the /tmp/${USER}_media mount points tree got not removed after
session end.
I am not sure about the latter two patches - could they create some
problems in case the user has two paralel sessions active? (Can it even
happen?)
Will you please review and possibly commit to git?
Regards,
Milan

I found one in the nx-libs-source/bin/ directory, but it doesn't make any sense, because it calls another x2goagent: NX_LIBS=/usr/lib/nx exec $NX_LIBS/../x2go/x2goagent $@ How did you solve the problem? Create a link to nxagent: ln -s /usr/lib/nx/nxagent /usr/lib/x2go/x2goagent I assume it is because of backward compatibility. The nxagent from nx-libs (NX redistributed) is patched so that it knows when it is run as x2goagent and when as nxagent. You can also have a look at the debian package to see what is installed and where: http://packages.x2go.org/debian/pool/main/n/nx-libs/x2goagent_3.5.0.10-0+wheezy~main~250~build1_all.deb Do not use x2goagent version older then 3.5.0.10, since these were a separate binary, not just a wrapper to NX redistributed nxagent.

[X2Go-Dev] X2Go bindings for Xfce and others
Hello, I have modified the existing LXDE bindings for X2Go so that it works with Xfce. I did some further modifications: x command to open folder is xdg-open x added generic-icon name to MIME type (folder-remote) As far as I understand the X2Go scripts, they check for GNOME/KDE/LXDE and add the corresponding letters to sshfs-disk-$DE MIME type. If none of the listed DEs is detected, the MIME type remains simply sshfs-disk. Since xdg-open and generic-icon name is general enough, it should work with other DE than Xfce, nonetheless, it has not been tested yet. I also updated the debian/ files but since I am on Arch Linux, I could not test the packaging process. P.S. I am aware about the plans for a unified approach for all DEs, which should make the gnome/kde/lxdebindings obsolete. So this is just a temporary solution. If you find it useful, will you add the x2gofmbinding to git? regards, Milan -- http://www.milan-knizek.net/ About linux and photography (Czech only) O linuxu a fotografování x2gofmbindings_1.0.1.1.tar.gz Description: GNU Zip compressed data ___ X2Go-Dev mailing list X2Go-Dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/x2go-dev

Re: [X2go-Dev] OT: exclude /usr/lib/x2go/libX11.so.6 from being linked by other apps
V Sat, 15 Oct 2011 20:32:38 +0300
Ivan Kabaivanov chep...@yahoo.com napsáno:
Hi Milan,
Hello Ivan,
check if /usr/lib/x2go is listed in /etc/ld.so.conf (or whatever
file/directory your distribution is using). If it is listed, remove
it and re-run /sbin/ldconfig. Then create a wrapper to start
x2goagent with the correct LD_LIBRARY_PATH.
The man page of ldconfig reads that /usr/lib is a trusted directory
and as such is not specified extra in /etc/ld.so.conf.d
nor /etc/ld.so.conf. /usr/lib/x2go is neither listed in the ld.so conf
files.
So far, the only problem seems to be with darktable, whose cmake script
looks in any subdir of /usr/lib - the configuration log file
shows it found x2go/libx11.so.6. I am not sure if it is an error of
darktable cmake configuration or if this is an expected behaviour.
Just for the curiosity, I have checked all binaries in /usr/bin and none
is dynamically linked to /usr/lib/x2go/...
Devs, perhaps it would be a good idea to change the x2goagent code
and rename the above libs to ${lib}-x2go.so.* or some such? Then
they can safely be installed in /usr/lib without fear of interfering
with other programs.
This could be a solution for me. As a workaround, I have simply
moved /usr/lib/x2go temporarily away and compiled darktable.
Thanks for the hints.
Regards,
Milan

Re: [X2go-Dev] x2golxdebindings (was Re: [X2go-User] Local share appears as a text file in $HOME/Desktop - cluttering the desktop)
Hello Mike, V Tue, 16 Aug 2011 14:14:34 +0200 Mike Gabriel mike.gabr...@das-netzwerkteam.de napsáno: Thanks for your input on this!!! Fixed in latest Debian package and in X2go Git (Ubuntu packages will follow some time during the next 24h automatically). I have further looked on git on the x2go*bindings and it seems that the default file manager for handling the shared (sshfs) mounted directory is hardcoded - i.e. nautilus for GNOME, pcmanfm for LXDE. How about using xdg-open for that? While it might make sense to expect that GNOME users have nautilus installed, users of less-fat environments usually prefer various file managers (thunar, pcmanfm) and not neccessarily the default one. I tried to edit /usr/bin/x2gopcmanfm and replace the command: system( pcmanfm $dir ); with system( xdg-open $dir ); and it seems to work just fine. What do you think? (If it is fine, then the command could actually be named more neutrally, like x2gofilemanager and also the corresponding x2gofilemanager.desktop file and also the definition of mime type sshfs-x2go.xml - which would lead to unification of the code across desktop environments.) regards, Milan -- http://www.milan-knizek.net/ About linux and photography (Czech only) O linuxu a fotografování ___ X2go-Dev mailing list X2go-Dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/x2go-dev
