Bug#946: [x2go-main| http://packages.x2go.org/opensuse/13.2/main] Valid metadata not found at specified URL

Package: x2goclient Version: 4.0.5 Hello! It seems to me that bug has nothing to do with particular package and its version so the information above needs to be ignore (I put it there because without it the email is not accepted). The problem is in absence of the valid metadata at specified URL. When I am trying to install x2goclient on opensuse 13.2 x64 from x2go-main and x2go-extras repos I get the following error: Error building the cache: [x2go-main|http://packages.x2go.org/opensuse/13.2/main] Valid metadata not found at specified URL Warning: Skipping repository 'x2go-main' because of the above error.

Bug#1015: Very old version of x2goclient (4.0.3.1-4) available for armhf
by Office NextITLevel GmbH 25 Nov '16

25 Nov '16

Package: x2goclient Version: 4.0.3.1-4 HW platform: armhf (all 5 Raspberry PI models) I do not know, if this is intentional that x2goclient is not available at http://packages.x2go.org/debian/pool/main/x/x2goclient/ for the ARMHF platform. This platform is used by the Raspberry PI. The new Raspberry PI 3 has a quad-core cpu and runs at 1,2 GHz. This should be good enough for an x2goclient. I did compile the source code once, but I do not want do to that all the time. I did however find an x2goclient 4.0.5.0-1 on the internet compiled for ARMHF. This client was compiled for Debian SID and not for Debian Jessie. So I installed the package manualy.

That was a standard Raspbian image with an added X2Go repo - I think Mike#2 hosts that. > How much effort would it be to make such image available for the > public? I would suggest providing a step-by-step install instruction like we have for the regular, x86/x64-based client, instead. Providing an image is almost like shipping a binary blob, and the SDcard is an 8 GB model, I think. Even compressed, that wastes a lot of server space. Also, the startup sequence I used was a bit hackish - X is running as root and starts up xmessage as a primitive menu, with one option then starting X2GoClient with the command line parameters for TCE mode. So it's not recommended for production use. Also, I would really recommend using a second-generation Raspi for performance reasons. > @all: does anyone of you have Rasberry Pis running a minimal X2Go > (Thin) Client system and are you willing to share (a) the > installation procedure or (b) the SD Card image? Karl-Heinz Hellmann and Franz L?ckl operate "niuco", a company that specializes in Raspberry-Pi-based ThinClients. They actually donated the Raspi you saw to the X2Go Project (thanks again for that!). I CC'ed them both, let's see what they have to add.

Bug#968: x2go runs "bash -c bash -c ..." on session create, causing dot bashrc issues
by Maarten Boekhold 13 Aug '16

13 Aug '16

Package: x2goserver Version: 4.0.1.19 When establishing a new x2go session, I noticed that my .bashrc file is read/sourced/executed many times, in the end screwing up my PATH and LD_LIBRARY_PATH settings (amongst others). I was surprised, because .bashrc is only supposed to be read when opening an interactive shell, and I am not expecting x2go to run interactive shells here. I did some debugging by placing the following at the start of my .bashrc: echo "bashrc" >> ~/slog ps -fea | grep boekhold >> ~/slog and based on this I can see x2go constantly running commands like: bash -c bash -c 'echo "X2GODATABEGIN:60b25f89-31db-46ec-8a7c-c93002fbfa50"; export PATH="/usr/local/bin:/usr/bin:/bin"; export HOSTNAME && x2golist still at first glance no reason for bash to process .bashrc. However, further testing: boekhold@xbmc:~$ rm slog rm: cannot remove ‘slog’: No such file or directory boekhold@xbmc:~$ bash -c date Sun Nov 22 19:39:09 GST 2015 boekhold@xbmc:~$ cat slog cat: slog: No such file or directory boekhold@xbmc:~$ bash -c bash -c date boekhold@xbmc:~$ cat slog bashrc boekhold 1147 1 1 Nov21 ? 00:20:20 ..... ..... See there? Running "bash -c bash -c" suddenly tricks bash into reading the .bashrc file. No idea how, but it happens. This is on Linux Mint 17.2, but I'm experiencing the same issue on a Centos 7 system with the x2go EPEL packages. Client is x2goclient on Windows 7 Professional SP1. I can't figure out where that "bash -c bash -c" command is being generated, hope that somebody from the X2Go team can provide some guidance here? Maarten

Bug#751: new DebBugs scripts: mbox / cleanbug
by Mike Gabriel 10 Aug '16

10 Aug '16

Hi all, last night, I created to new scripts for the debbugs software underneath bugs.x2go.org. Both scripts are attached and can be found under /usr/lib/debbugs on host ymir.das-netzwerkteam.de. Especially the cleanbug script should be of interested here. I recently received various abuse notifications from my provider and they all relate to X2GO bugs containing mails with virus attachments. These need to be cleaned. I already did so for the reported URLs: http://bugs.x2go.org/128 http://bugs.x2go.org/232 http://bugs.x2go.org/496 http://bugs.x2go.org/765 But there are more... Please coordinate in the X2Go core team, who will work on cleaning up the X2Go bugtracker. Currently, these people have access: Heinz Mihai Mike You have to log into ymir.das-netzwerkteam.de (aka bugs.x2go.org) as user locadm and become root via sudo. The cleanbug script itself is easy to handle: # /usr/lib/debbugs/cleanbug <bugno> Once you triggered the script, you have to look at bug posts on the selected bug and say yes and no. At the end you get asked, if you really want to write back the changes to the bug. The answer's question defaults to "no". You should create some back before manipulating existing bugs. For this, create copies of <bugno>.log in /var/lib/debbugs/spool/db-h/ Note for archived bugs: for cleaning up archived bugs, you have to unarchive them first.

Question about x2goclient xinerama
by Ulrich Sibiller 14 Jul '16

14 Jul '16

Hello, while testing my xinerama re-implementation I noticed that x2goclient reports a wrong width sometimes when simply moving the window without changing the size. The reported size differs by one pixel (too much or too little). When running x2goclient --debug you can see this: x2go-DEBUG-../src/onmainwindow.cpp:10160> "New proxy geometry: (x: 329, y: 214, w: 1440, h: 900" x2go-DEBUG-../src/onmainwindow.cpp:10160> "New proxy geometry: (x: 365, y: 213, w: 1440, h: 900" x2go-DEBUG-../src/onmainwindow.cpp:10160> "New proxy geometry: (x: 825, y: 190, w: 1440, h: 900" x2go-DEBUG-../src/sshprocess.cpp:189> executing remote command via SshProcess object (24): "export DISPLAY=:50;printf '\''1095 0 345 900\n0 0 1095 900'\'' > $HOME/.x2go/C-uli-50-1431636769_stDKDE_dp24/xinerama.conf" -> here the 345 should have been a 344. Interestingly my patched x2goagent (that completely ignores xinerama.conf) sees that value. So I conclude that x2goclient is manipulating the nxproxy window size by one pixel itself. Disabling xinerama in the session's configuration fixes the problem. That off-by-one behaviour is caused by this code in onmainwindow.cpp: void ONMainWindow::slotXineramaConfigured() { if (resumingSession.fullscreen) return; if (xinSizeInc == -1) xinSizeInc=1; else xinSizeInc=-1; #ifdef Q_OS_LINUX lastDisplayGeometry.setWidth(lastDisplayGeometry.width()+xinSizeInc); XSync(QX11Info::display(),false); XResizeWindow(QX11Info::display(), proxyWinId, lastDisplayGeometry.width(),lastDisplayGeometry.height()); XSync(QX11Info::display(),false); #endif #ifdef Q_OS_WIN QRect geom; wapiWindowRect ( (HWND) proxyWinId, geom ); wapiMoveWindow( (HWND) proxyWinId, geom.x(), geom.y(), geom.width()+xinSizeInc, geom.height(),true); lastDisplayGeometry=proxyWinGeometry(); #endif xineramaTimer->start(500); } If I set xinSizeInc to zero in all cases the off-by-one behaviour is completely gone. Why does xinSizeInc exist at all? Uli
