Fullscreen mode in Windows not working
by John A. Sullivan III 22 Mar '10

22 Mar '10

Hello, all. I've been testing X2Goclient 3.0.1-4 for Windows on two separate computers running WindowsXP. I'm seeing the same problem on both. I set the session mode to full screen and yet the session opens to some less than full screen geometry with Window decorations. I have ensured the old sessions were not running so it was not inheriting old geometry. Is this a bug or am I doing something wrong? Thanks - John

Out of order key strokes
by John A. Sullivan III 20 Mar '10

20 Mar '10

Hello, all. I've been observing a serious issue with enough consistency that I'll report it. On highly congested links, we are noticing that keystrokes are delivered out of order. I do not know the internals of NX or even what its underlying transport is. It almost appears as if every keystroke is a packet as it is with telnet and the packets are being processed in their out of order sequence. I would think that SSH over TCP would handle packet ordering problems. When severely congested, the typing speed on the remote desktop becomes very lagged but, if one types far enough ahead, the far end of the buffer is played out of order particularly when there are the same characters close to each other (perhaps a compression bug? we have not done enough observation on that to state it dogmatically). For example, I don't know how many times today I typed something like "shared database in a complete" and had it come out "sharedd ataabse ina compleet" (in case that is displayed across a line break, there are two spaces between ataabse and ina). This can be exasperating to our clients when links are congested. It's one thing to have to wait for the display while it's another to see the display display something other than what was typed :-) Thanks - John

Old session directories
by John A. Sullivan III 14 Mar '10

14 Mar '10

I'm noticing we are building up quite a collection of old session directories (S- and C- directories under ~/.x2go). Is there any reason why we keep these and don't delete them once the session is terminated? Thanks - John

Working on x2goclient code
by John A. Sullivan III 14 Mar '10

14 Mar '10

Hello, all. I'm both trying to deeply understand the workings of X2Go and trying to troubleshoot a problem we are having with SSH keys after replacing an X2Go Server. >From where does one checkout the repository? I'm not that used to Berlios and it didn't jump out at me. I did download the 3.01-4 tarball and tried to run it on my default Lenny installation of KDevelop. It complains that QtDesigner is too old. It's also complaining about paths when I try to run the debugger. Any tips for getting set up to work on the Qt code? Thanks - John

x2gosessionlimit and user limits
by John A. Sullivan III 14 Mar '10

14 Mar '10

Hello, all. We're finally starting to work our way thoroughly through the x2go scripts and were a little confused by x2gosessionlimit. Given the following logic: my $runningsessions=`x2golistsessions --all-servers`; my @sessions=split("\n",$runningsessions); my $scount=@sessions; my $strlimit=$Config->param("limit users.$uname"); if($strlimit ne "") { if($strlimit == 0) { print "0\n"; exit 0; } if($strlimit <= $scount) { print "$strlimit\n"; exit 0; } print "$strlimit\n"; exit 0; } If a user is limited to the 3 sessions and x2golistsessions returns 1, $strlimit is ne "" so we will enter the block. It is neither 0 nor <= 1 so we will print "3\n". Doesn't this cause x2gostartagent to exit with an error? LIMIT=`x2gosessionlimit` LWORD=`echo $LIMIT | awk '{print $1}'` if [ "$LWORD" == "LIMIT" ] then echo $LIMIT exit -1 fi Thanks - John

cups-x2go for multiple X2Go Servers
by John A. Sullivan III 09 Mar '10

09 Mar '10

Hello, all. I'm stumbling through how to have a central cups server provide cups-x2go printing for multiple X2Go Servers. It seems the cups-x2go backend looks to the cups-x2go.conf file to specify the X2Go Server and only accommodates a single server. We want it to service hundreds or more. I see that the cups-x2go backend takes "cups-x2go job-id user title copies options [file]" as arguments. My current endeavor is to query the sessions database for the user to find the server but that presents the problem of when a user may have sessions on multiple servers. Is there any way to pass (even by hacking the code) the hostname of the originating X2Go Server as an argument? That would eliminate the need for the database call and make it more foolproof. Thanks - John PS - it looks like I've been able to move the x2gocleansessions processing to a central process for cleaning up hundreds of X2GoServers in a VServer 1-to-1 environment. As soon as I steer clear, I'll post the patches and documentation - John

Single application sessions terminate with certain mouse movements
by Hein-Pieter van Braam 07 Mar '10

07 Mar '10

Hello list, I'm having a strange problem with x2go in single application mode. Whenever I start an application and I move my mouse from within the application 'up' to the window decoration the session gets terminated on the client side. I can reconnect to the program, but it will crash again if I do the same mouse movement. I have tried this with GTK programs, xterm and xcalc and the situation remains the same. My setup is Debian Sid x86_64 with windowmaker. The problem also occurs when using blackbox. Could someone perhaps tell me what I can do to debug this further? Thanks! Hein-Pieter van Braam

x2gocleansessions order change?
by John A. Sullivan III 07 Mar '10

07 Mar '10

Hello, all. I'm working on adapting the x2gocleansessions script to handle session cleanup from a VServer host for all of its guests. In working my way through the script, something seemed a bit strange. It looks like we attempt to delete sessions with a status of "F" before we delete the mounts for that sections which leads to a foreign key constraint violation. Shouldn't the rmsessionsroot call in x2golistsessions_sql be broken out separately and executed after x2goumount_session? I'd imagine there's something I'm missing but thought I'd at least ask. I'll submit the patches and documentation once I've got it working. Thanks - John

BUG: bash login shell required ...
by armin 04 Mar '10

04 Mar '10

the session management will fail if you connect to a X2Go server and your default login shell deviates from a BASH. reason: any client tries to export the host environment variable before it starts x2glistsession. export only works for BASH and not e.g. for tcsh. if someone is responding to that bug-report i can offer a workaround .. (i just want to find out if someone is interested in ;) cheers armin

Copy & Paste from between windows client and x2go server
by georgehu 03 Mar '10

03 Mar '10

I have installed x2go server on my ubuntu machine, and a windows client, x2goclient-3.01-4-setup.exe. Everything works perfectly except for one: I couldn't copy & paste text between windows and my ubuntu gnome desktop. Is this a feature not included in the x2go or I missed something? Thanks... George Hu
