Bug#884: nxagent fails to run with "Could not open default font 'fixed'"

Package: nx-libsVersion: 3.5.0.30Distro: Gentoo ~amd64, fully updated.x2goclient: 4.0.3.2x2server: 4.0.1.19nx-libs (package nx in gentoo): 3.5.0.30fontsproto: 2.1.3libXfont: 1.5.1xorg-server: 1.17.1All font packages for xorg-x11 are installed and fonts.dir and fonts.alias files are correctly present and readable.Detailed troubleshooting: https://forums.gentoo.org/viewtopic-p-7755384.html The client connects and the server spawns the nxagent but then the session is unexpectedly terminated. … [View More]Looking at the server side log, we see: Info: Using shared memory parameters 1/1/0/0K.

Session: Aborting session at 'Tue May 26 23:22:22 2015'. Session: Session aborted at 'Tue May 26 23:22:22 2015'. I ran the nxagent through strace -ff -tt -v and its clear that it loads all fonts (at least it finds all font.alias and reads them fine) correctly. None of the children it spawns run into any issues with missing files or folders.

Anybody got any ideas of why this is happening? Is it really about the newer fontsproto and libXfont not being compatible with nx-libs? Thanks,devsk [View Less]

Hi, As per suggestion I built the code from https://github.com/ArcticaProject/nx-libs. And I still run into the same issue. Does anybody here know that part of the code (snippet in the report)? -devsk

Bug#731: if KRB5CCNAME is not set client-side, don't trigger the KRB5 delegation code

Bug#946: [x2go-main| http://packages.x2go.org/opensuse/13.2/main] Valid metadata not found at specified URL
by knawnd＠gmail.com 04 Dec '16

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.… [View More]

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#1053: armhf for debian jessie repo broken

As there is no comment on my report, I would recommend to disable the jessie armhf repo altogether. It does have unresolved dependencies and therefore is an unusable debian repository. Chris

Bug#799: x2golistdesktops - ss options
by Orion Poplawski 10 Nov '16

10 Nov '16

So, it appears to be well known that 'ss -lxu' has been broken on some systems and returns nothing. This is currently true on EL 7.2 though appears fixed in 7.3 beta. However, why is -u being passed to ss in the first place? We're doing: my $lines=system_capture_stdout_output("ss", "-lxu"); my @lines=split("\n", "$lines"); my @outp = grep ( /(@| )\/tmp\/.X11-unix\/X.*/, @lines); for(my $i=0;$i<@outp;$i++) { ... so we're filtering the output of ss for lines that look like unix sockets … [View More]
