Bug#554: Disable local screensaver when x2go session is in fullscreen mode
by Reinhard Tartler 30 Jan '24

30 Jan '24

Package: nxproxy Severity: serious I noticed that the when nxproxy is in fullscreen mode, it (by design) captures all keyboard strokes. This is in general great because this way all keyboard shortcuts on the remote work. However, the local screen saver might still kick in and require a password. Because the nxproxy captures all input, a less carefull user might enter his local password into the current application that is running in the x2go session. When the remote application happens to be a chat application, entering your password might have serious security implications. I think a fullscreen nxproxy is a good reason to inhibit the local screensaver. -- regards, Reinhard

Bug#1125: Remote printing not working in Debian Jessie
by JR 30 Jan '24

30 Jan '24

Package: cups-x2go Version: 3.0.1.3-0x2go1+git20161129.135+8.main.1 I tried printing on the local PC from the x2goclient without success. x2goclient gives no message. I installed x2goserver-printing, cups, cups-x2go and I have installed x2go virtual printer. This happens to me only in Q4OS 1.18-Orion (Debian Jessie based). In Q4OS 2.2-Scorpion (Debian Stretch based) it works perfectly. For more details, please give a look at: http://www.q4os.org/forum/viewtopic.php?id=1261 Thank you and congratulations for your work.

Bug#740: Ship a default, small-footprint, F/LOSS PDF viewer with x2goclient
by Stefan Baur 30 Jan '24

30 Jan '24

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 package: x2goclient severity: wishlist Hi, this is actually a sub-bug of http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=738. I am fling it as a separate bug because I believe this particular part of Bug 738 can be resolved rather quickly. Currently, X2GoClient offers the free choice of X-Servers to be used with it, but ships with VcXsrv as default and has some "sane" default settings configured for it, too, so X2GoClient works out of the box. Whoever wishes to deviate from that path, is, however, free to do so - X2GoClient has an option to specify a custom X-Server of the user's choice. I would like to take a similar approach for printing. At present, no default PDF viewer is shipped with X2GoClient, and the user has to fiddle with whichever PDF viewer they choose to get the parameters right. SumatraPDF is a free (F/LOSS) PDF viewer that offers a portable version, i.e. it is a single, self-contained executable that doesn't require any installation. It also supports a wide range of command line parameters so it is ideal for scripted background use (like "open PDF, print to default printer, close application"). Quoting from http://www.sumatrapdfreader.org/manual.html: > Printing related cmd-line arguments: -print-to-default $file.pdf > prints a PDF file on a default printer -print-to $printer_name > $file.pdf prints a PDF on a given printer -print-dialog $file.pdf > opens a PDF file and shows a print dialog to select printer and > printing options -exit-on-print when -print-to-default or -print-to > is used, will exit after printing So, basically, "-exit-on-print -print-to-default" is all we'd need for basic functionality. If we want to do "enumPrinters" within X2GoClient, "-exit-on-print -print-to $printer" will also already work. If we want to leave printer selection to SumatraPDF, "-print-dialog" has to be used, and we'd probably have to submit a patch to the SumatraPDF project that "-exit-on-print" be made to work with "-print-dialog" as well, as the current description seems to indicate that this is not the case. Thus, I would ask that some helpful soul steps up and please a) includes SumatraPDF's standalone executable in the Windows X2GoClient package b) adds the proper code to X2GoClient so client-side printing defaults to using SumatraPDF in the X2Go program directory unless the user has created a custom configuration. The rationale for this bug is that adding this feature would increase usability of X2GoClient just as shipping a default X-Server does.

Package: src:nx-libs Severity: important The NX source code uses gethostbyname() at several locations and is potentially affected by CVE 2015-0235 (GHOST security issue in glibc). We should move towards using getaddrinfo() asap.

Bug#694: CUPS 1.7.x remounts /tmp and breaks cups-x2go
by Mike Gabriel 25 Jan '24

25 Jan '24

Package: cups-x2go Severity: important The workaround provided below can be applied to x2goprint from x2goserver-printing package. But my gut feelings tell me, we need to review cups-x2go. Maybe this bug gets reassigned to x2goserver-printing later, if my gut feelings get proven wrong. Mike ----- Weitergeleitete Nachricht von Роман <inpos(a)yandex.ru> ----- Datum: Mon, 01 Dec 2014 10:59:36 +0300 Von: Роман <inpos(a)yandex.ru> Betreff: [X2Go-User] X2Go Linux Server. Virtual print issue workaround An: x2go-user(a)lists.x2go.org For those who can't print to redirected printer here my workaround. On X2Go Server do following (by root): ---------------------------------------------- cd /usr/bin mv x2goprint x2goprint.orig cat << EOF > x2goprint #!/bin/bash umount /tmp x2goprint.orig $@ EOF chmod a+x x2goprint ----------------------------------------------- The problem is that CUPS remounts /tmp during print process. Therefore temporary x2go directories have become unavailable.
