+x2goserver (3.1.1.1-0~x2go1) unstable; urgency=low
+
+ [ Mike Gabriel ]
+ * New upstream version (3.1.1.1):
+ - Add/fix Python X2Go folder sharing/unsharing support from Windows.
+ - Handle whitespace in folder names appropriately.
+ - Allow .desktop file parameter Terminal=... to pass through to X2Go
+ client-side.
+ - Avoid error messages in x2gocmdexistmessage if cmdoutput file could
+ not be found.
+ - Provide nx-X11 libraries for applications launched via x2goruncommand.
+ - Add feature X2GO_SERVERSIDE_DESKTOPCOMMANDS. Let client provide a generic
+ desktop shell command (GNOME, UNITRY, KDE, etc.) which then gets
+ translated into an executable command by x2goruncommand.
+ - Detect desktop session mode to use for Ubuntu precise and later.
+ - Complete UNITY/GNOME support for Ubuntu/Debian.
+ - Use ,,-nolisten tcp'' option when evoking x2goagent from within
+ x2gostartagent.
+ - Export NX_ROOT=$HOME/.x2go in x2gostartagent. Makes the keyboard file
+ in X2Go session cache directory.
+ - Add support for client-side keyboard detection. Moved script
+ x2gosetkeyboard from x2goserver-pyhoca into x2goserver package.
+ - Make x2gosetkeyboard set the client-side keyboard on session start and
+ resume if usekbd is set to True and the keyboard type is set ,,auto''.
+ - Reset keyboard settings to pc104/us before setting client-side keyboard
+ parameters.
+ - For finished sessions purge all mount points that still hover in the
+ DB's mounts table.
+ - Make sure we run fusermount from within a directory that the user has read
+ access to.
+ * Depend on x2goagent (>= 2:3.5.0.12), make sure that x2goagent has the patch
+ 105_nxagent_export-remote-keyboard-config.full.patch included.

-.SH DESCRIPTION
-\fBx2gosetkeyboard\fR looks for a 'keyboard' file in the X2Go session directory and introspects
-the X2Go session keyboard settings requested from the client side.
-.PP
-If no 'keyboard' file is present in the X2Go session directory, nothing happens (i.e. no error
-will be raised).
-.SH RETURN VALUES
-If \fBx2gosetkeyboard\fR successfully sets the session's keyboard parameters an exit code of 0 is
-returned. Also, if the file ${HOME}/.x2go/C-${X2GO_SESSION}/keyboard is not presented at the
-expected location, a zero-exitcode is returned.
-.PP
-If the command fails on its way, then the exitcode of the failing command is returned.
-.SH FILES

-% @multitable macros
-% Amy Hendrickson, 8/18/94, 3/6/96
-%
-% @multitable ... @end multitable will make as many columns as desired.
-% Contents of each column will wrap at width given in preamble. Width
-% can be specified either with sample text given in a template line,
-% or in percent of \hsize, the current width of text on page.
-
-% Table can continue over pages but will only break between lines.
-
-% To make preamble:
-%
-% Either define widths of columns in terms of percent of \hsize:
-% @multitable @columnfractions .25 .3 .45
-% @item ...
-%
-% Numbers following @columnfractions are the percent of the total
-% current hsize to be used for each column. You may use as many
-% columns as desired.
-
-
-% Or use a template:
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item ...
-% using the widest term desired in each column.
-
-% Each new table line starts with @item, each subsequent new column
-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab do not need to be on their own lines, but it will not hurt
-% if they are.
-
-% Sample multitable:
-
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item first col stuff @tab second col stuff @tab third col
-% @item
-% first col stuff
-% @tab
-% second col stuff
-% @tab
-% third col
-% @item first col stuff @tab second col stuff
-% @tab Many paragraphs of text may be used in any column.
-%
-% They will wrap at the width determined by the template.
-% @item@tab@tab This will be in third column.
-% @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.
-% @multitablelinespace is space to leave between table items, baseline
-% to baseline.

-% tex foo.texi
-% texindex foo.??
-% tex foo.texi
-% tex foo.texi
-% dvips foo.dvi -o # or whatever; this makes foo.ps.

-% Amy Hendrickson, 8/18/94, 3/6/96
-%
-% @multitable ... @end multitable will make as many columns as desired.
-% Contents of each column will wrap at width given in preamble. Width
-% can be specified either with sample text given in a template line,
-% or in percent of \hsize, the current width of text on page.
-
-% Table can continue over pages but will only break between lines.
-
-% To make preamble:
-%
-% Either define widths of columns in terms of percent of \hsize:
-% @multitable @columnfractions .25 .3 .45
-% @item ...
-%
-% Numbers following @columnfractions are the percent of the total
-% current hsize to be used for each column. You may use as many
-% columns as desired.
-
-
-% Or use a template:
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item ...
-% using the widest term desired in each column.
-
-% Each new table line starts with @item, each subsequent new column
-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab do not need to be on their own lines, but it will not hurt
-% if they are.
-
-% Sample multitable:
-
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item first col stuff @tab second col stuff @tab third col
-% @item
-% first col stuff
-% @tab
-% second col stuff
-% @tab
-% third col
-% @item first col stuff @tab second col stuff
-% @tab Many paragraphs of text may be used in any column.
-%
-% They will wrap at the width determined by the template.
-% @item@tab@tab This will be in third column.
-% @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.
-% @multitablelinespace is space to leave between table items, baseline
-% to baseline.
-% 0pt means it depends on current normal line spacing.

X2go Thin Client Environment
============================
-This howto is intended for Debian squeeze (and newer Debian versions)
+A detailled installation description is available in the X2Go Wiki:
+http://wiki.x2go.org/doku.php/wiki:components:tce
-Server Installation
--------------------
-(use a separate server or VM for providing thin
-client chroots, do not use your production Samba, LDAP, Apache2 etc. server
-for this!!!)
-
- $ apt-get install dhcp atftpd nfs-kernel-server debootstrap
-
-
-Installation Thin Client Environment (TCE)
-
-Choose folder for your TCE chroot (e.g. /opt/x2gothinclient)
-
-Install TCE:
-
- <TODO: REVIEW/FIXME (use aptitude instead of apt-get)>
- $ debootstrap --arch i386 lenny /opt/x2gothinclient http://ftp.de.debian.org/debian/
- $ cp /etc/resolv.conf /opt/x2gothinclient/etc/
- $ echo "auto lo
- $ iface lo inet loopback" >> /opt/x2gothinclient/etc/network/interfaces
- $ echo x2gothinclient > /opt/x2gothinclient/etc/hostname
- $ echo "127.0.0.1 localhost" >> /opt/x2gothinclient/etc/hosts
-
-Repeat these steps for any of your X2Go servers:
-
- <TODO: REVIEW/FIXME (use aptitude instead of apt-get)>
- $ echo "192.168.0.1 x2goserver" >> /opt/x2gothinclient/etc/hosts
- $ chroot /opt/x2gothinclient/
- $ echo "deb http://x2go.obviously-nice.de/deb/ lenny main" >> /etc/apt/sources.list
- $ apt-get update
- $ apt-get install locales
- $ dpkg-reconfigure locales
-
-Edit /etc/initramfs-tools/initramfs.conf to boot from NFS:
-
- <TODO: REVIEW/FIXME (use aptitude instead of apt-get)>
- $ apt-get install kernel-image-2.6-686 syslinux
- $ apt-get install x2gothinclientsystem
- $ cd /usr/share/x2gothinclientsystem/script/
- $ ./x2gothinclient_install.sh
-
-After a successful TCE configuration you now can leave the chroot environment:
-
- $ exit
-
-Server Configuration:
----------------------
-
-atftpd: (e.g. /etc/default/atftpd)
-
-------------------------
-USE_INETD=false
-OPTIONS="--daemon --port 69 --tftpd-timeout 300 --retry-timeout 5 --mcast-port 1758 --mcast-addr 239.239.239.0-255 --mcast-ttl 1 --maxthread 100 --verbose=5 /tftpboot"
-------------------------
-USE_INETD=false
-
-If inetd is not used for aftpd then you can start/stop aftpd with "/etc/init.d/atftpd start|stop".
-
-NOTE! If you intend running aftpd in standalone mode make sure that no other tftpd server is active in inetd/xinetd
-configuration.
-
-The last argv in OPTIONS (s. above) declares the folder for tftp boot. The default is "/tftpboot".
-
- $ mkdir /tftpboot
-
-PXE boot configuration:
-
- $ cp /opt/x2gothinclient/boot/vmlinuz-* /tftpboot/
- $ cp /opt/x2gothinclient/boot/initrd.img-* /tftpboot/
- $ ln -s /tftpboot/vmlinuz-* /tftpboot/vmlinuz
- $ ln -s /tftpboot/initrd.img-* /tftpboot/initrd.img
- $ cp /opt/x2gothinclient/usr/lib/syslinux/pxelinux.0 /tftpboot/
-
-Example: /tftpboot/pxelinux.cfg/default
-
----------------------
-label linux
-kernel vmlinuz
-append root=/dev/nfs nfsroot=192.168.0.1:/opt/x2gothinclient ro initrd=initrd.img ip=dhcp
---------------------
-
-The given ip address 192.168.0.1 refers to the address of the host that your TCE chroot is installed on.
-
-DHCP:
-
-<TODO/FIXME (update for DHCP3 server + translate into English)>
-Bestimmen Sie in Datei "/etc/default/dhcp" auf welche Interfaces soll dhcpd laufen.
-Beispiel /etc/dhcpd.conf:
---------------------
-group
-{
- subnet 192.168.0.0 netmask 255.255.255.0 {
- default-lease-time 720000;
- max-lease-time 1440000;
- authoritative;
- range 192.168.0.10 192.168.0.100;
- filename "/pxelinux.0";
- next-server 192.168.0.1;
- }
-}
---------------------
-
-NFS (/etc/exports):
---------------------
-/opt/x2gothinclient 192.168.0.0/24(ro,async,no_root_squash)
---------------------
-
-X2go Server in LDAP
--------------------
-
-Do not forget to store you X2Go servers in LDAP. Use
-
- $ ldap.addserver <name> <ip>
-
-to add an X2Go server to the LDAP tree.
