Client-side printing still not working
by Stefan Baur 20 Dec '11

20 Dec '11

Hi List, I'm still having issues getting client-side printing to work. The server is running Debian Squeeze, with the following X2Go- and CUPS-related packages installed: ii cups 1.4.4-7+squeeze1 Common UNIX Printing System(tm) - server ii cups-bsd 1.4.4-7+squeeze1 Common UNIX Printing System(tm) - BSD commands ii cups-client 1.4.4-7+squeeze1 Common UNIX Printing System(tm) - client programs (SysV) ii cups-common 1.4.4-7+squeeze1 Common UNIX Printing System(tm) - common files ii cups-driver-gutenprint 5.2.6-1 printer drivers for CUPS ii cups-ppdc 1.4.4-7+squeeze1 Common UNIX Printing System(tm) - PPD manipulation utilities ii cups-x2go 3.0.0.3-0~x2go1+squeeze~main~54~build1 X2GO printer for CUPS ii cupsddk 1.4.4-7+squeeze1 Common UNIX Printing System (transitional package) ii cupsys 1.3.8-1+lenny10 Common UNIX Printing System (transitional package) ii cupsys-client 1.3.8-1+lenny10 Common UNIX Printing System (transitional package) ii ghostscript-cups 8.71~dfsg2-9 The GPL Ghostscript PostScript/PDF interpreter - CUPS filters ii hplip-cups 3.10.6-2 HP Linux Printing and Imaging - CUPS Raster driver (hpcups) ii libcups2 1.4.4-7+squeeze1 Common UNIX Printing System(tm) - Core library ii libcupscgi1 1.4.4-7+squeeze1 Common UNIX Printing System(tm) - CGI library ii libcupsdriver1 1.4.4-7+squeeze1 Common UNIX Printing System(tm) - Driver library ii libcupsimage2 1.4.4-7+squeeze1 Common UNIX Printing System(tm) - Raster image library ii libcupsmime1 1.4.4-7+squeeze1 Common UNIX Printing System(tm) - MIME library ii libcupsppdc1 1.4.4-7+squeeze1 Common UNIX Printing System(tm) - PPD manipulation library ii libxcompext3 1:3.5.0-1-0~x2go-bpo1+lenny~main~36~build1 NX X11 protocol compression extensions library ii libxcompshad3 3.5.0-2-0~x2go-bpo1+lenny~main~24~build1 NX shadowing library ii x2go-keyring 2011.12.07+squeeze~main~12~build1 GnuPG keys of X2go developers ii x2goagent 3.5.0.2-0~x2go1+squeeze~main~49~build1 Special X2go-ized X agent, forked from NX-X11 (NoMachine) ii x2goserver 3.0.99.8-0~x2go1+squeeze~main~373~build1 X2go server daemon scripts ii x2goserver-extensions 3.0.99.8-0~x2go1+squeeze~main~373~build1 X2go server daemon scripts (extensions) ii x2goserver-printing 3.0.99.8-0~x2go1+squeeze~main~373~build1 X2go server daemon scripts (printing) I decided not to update the two libxcomp* packages, as they don't seem relevant to the issue and trying to update them means temporarily adding heuler sources, which I'd like to avoid. As you can see, I now have both printing-related packages installed: cups-x2go and x2goserver-printing. I tried adding the printer via the CUPS web interface, and also via the commandline (lpadmin -p "Virtual_X2GO_Printer" -v "cups-x2go:/" -D "Virtual X2GO Printer" -L "local workstation printer" -E -m "lsb/usr/cups-x2go/CUPS-X2GO.ppd"), to see if it makes a difference - it does not. On the client side (Windows 7 Home Premium, German, 32-bit) I installed X2Go Client V. 3.99.0.2. I enabled client-side printing in the session settings, and configured the local default printer in the X2Go Client general settings. I also tried the other options like having the PDF shown instead, or the "save PDF file" option. Nothing happens when I try to print (I tried to print a test page from the CUPS web interface as well as a web page from the browser). CUPS claims to have processed the job, but it goes nowhere. I also tried a Windows XP SP3, German, 32-bit client, with the same settings - same result. :-( Does Client-side printing only work with full desktop sessions? (I only tried it with a single application - the web browser - as I don't have a full DE installed on that server.) What do I have to do to get this working? Kind Regards, Stefan

But at the moment we have other opinion. Would you accept a patch to toggle between your current UI and a more compact one, if I paid Mike or some other developer to add it? Or would such an addition have to remain a fork of your official client? Kind Regards, Stefan

re x2go plugin for Remmina
by brian mullan 18 Dec '11

18 Dec '11

I had used Remmina extensively before I found out about x2go. Its a very nice application. The Remmina developers are now implementing the new freerdp 1.0 release into Remmina which will let Windows 2008r2 server applications that are configured for RemoteAPPs to be run individually in an x-window on your linux desktop just like any other linux app, resize, minimize/maximize, print local, save local etc. Re: [Freerdp-devel] UDS: FreeRDP + Remmina Integration in Ubuntu 12.04 Discussion Marc-André Moreau Thu, 24 Nov 2011 13:03:26 -0800 Hi, I said in my previous email that I would post the link when the "lightning talks" video from UDS would be available. It's been uploaded this week:http://www.youtube.com/watch?v=Qnh7f36xkRA FreeRDP is first to go, we demoed RemoteApp and RemoteFX.

It is going to be replacing rdesktop in the 12.04 ubuntu release from what I've heard. Anyway... I had suggested to the Remmina devs a month ago that they ought to look at supporting x2go in their application since they already support rdp, nomachine nx, vnc etc. Remmina has a very nice user interface.. it just doesn't have x2go .. yet?

Lauchpad and Git branches - now possible
by Moritz Struebe 11 Dec '11

11 Dec '11

Hi there, for another project I just discovered this comment: https://bugs.launchpad.net/launchpad/+bug/380871/comments/32 and it works! We can therefore add a dev-branch and just rebase that to master once things are working. IMO this is Mikes decision, though. :) Cheers Morty -- Dipl.-Ing.

Display errors in color picker
by Stefan Baur (newsgroups-Kontakt) 11 Dec '11

11 Dec '11

Hi list, the attached image shows a display error that occurs when you try to set the desktop background color in LXDE. The funny thing is that I've seen this error before: When using KDE 3 and NoMachine NX/FreeNX. Does anybody know how to fix this? Client is Windows 7 Home Premium (32-bit, German) with 32-bit color depth and the X2go client version is 3.99.0.2. Connection speed is set to ADSL, compression method is set to 16m-jpeg and image quality is set to 9. Server is Debian Squeeze with the latest packages and patches installed - Mike Gabriel was kind enough to provide me with an account on his test server while mine is undergoing repairs. Kind Regards, Stefan

Printing-related question for Windows X2go client users
by Stefan Baur (newsgroups-Kontakt) 10 Dec '11

10 Dec '11

Hi list, this question goes out to all the Windows users of the X2go-Client: Has anybody ever tried to use "Sumatra PDF" as a PDF endpoint on the Windows client, instead of Adobe Reader? It seems rather interesting, as it is GNU licensed, offers commandline options to print a file to the default printer (or show a print dialog) and auto-terminate itself after printing has finished (look for "Command-line arguments" in the online manual linked below). Info in English: http://en.wikipedia.org/wiki/Sumatra_PDF http://blog.kowalczyk.info/software/sumatrapdf/manual.html Info in German: http://de.wikipedia.org/wiki/Sumatra_PDF http://blog.kowalczyk.info/software/sumatrapdf/manual-de.html I'd love to try it out myself, but I haven't managed to get printing/showing a PDF on the Client to work at all so far, thus testing Sumatra PDF doesn't really make sense on my client yet. So here's to crowdsourcing - anybody ever tried it, anybody with a working client printer setup willing to try? Kind Regards, Stefan

I am in contact with Mike, and will also give his client a try (especially as he offered to add/change features if paid for), but IMO, these features make sense in the "mainline" client. -Stefan

Two problems (crashes) with X2goclient for Microsoft Windows
by Stefan Baur 02 Dec '11

02 Dec '11

Hi List, subject says it all, so here's a short description of the test environment: Server is a vserver running Debian Lenny (oldstable/5.0.9) but the 2.6.32-5-vserver-amd64 kernel (as the host is Debian Squeeze). dpkg -l|grep x2go ii nxcompshad 3.4.0-1-1 nx based library needed by the x2go system ii x2go-keyring 2011.04.19+lenny~main~10~build1 GnuPG keys of X2go developers ii x2goagent 3.4.0-3-1 Special NX-ized client, was developed by NoMachine to handle X ii x2goserver 3.0.99.8-0~x2go-bpo1+lenny~main~388~build1 X2go server daemon scripts ii x2goserver-extensions 3.0.99.8-0~x2go-bpo1+lenny~main~388~build1 X2go server daemon scripts (extensions) Client is "Windows 7 Home Premium", 32-Bit, running X2Go Client V.3.99.0.1 (Qt-4.5.3) - not a clean install, but installed over a previous, older version. 1) Accidentally attempting to connect to the wrong server crashes the client. What happened: * Host is configured to use private key files and doesn't have a corresponding user * Vserver is running sshd on a different IP/port * Client connects to the host instead of the vserver due to the wrong port number, using password-interactive authentication, which is denied by the server, also, there is no user present on the host that matches the given username ==>Crash (System message offering to close the program or look online for help) 2) Attempting to connect to a host that has a different ssh key than the one seen previously shows a small popup "Authentication failed" that complains about the offending key, but it immediately causes a Crash (same as above) - there's not even a chance to click on the "OK" button of that popup. Both cases should be handled more gracefully. Kind Regards, Stefan
