x2goruncommand is not exiting after logout in some distros
by Oleksandr Shneyder 20 Mar '24

20 Mar '24

Hi all, who wrote this in /usr/bin/x2goruncommand?: --------------------------------------------- # This is gonna be a nasty trick now... # Most applications run in foreground (fine!), but some fork to background (urgghh... e.g. konsole, iceweasel, etc.). # By capturing their STDOUT, we force the process to remain in (sort of) foreground until the process has finished. # This works fabulously with all applications that don't cleanly close their file descriptors (which is probably # 99% of all applications out there...). STDOUT=`$EXEC_WRAPPER $cmd$args` ------------------------------------------------ looks like some DEs for example XFCE and Plasma on Ubuntu22 and Alma9 starting some processes which are occupying stdout and not terminating them after logout. As result after logout user have a blank screen which stays forever, that can be very confusing. We should remove it at least for desktop sessions. Replacing the line STDOUT=`$EXEC_WRAPPER $cmd$args` with $EXEC_WRAPPER $cmd$args fixing the problem. regards, Alex -- ----------------------------------------------------------- Oleksandr Shneyder | Email: o.shneyder(a)phoca-gmbh.de phoca GmbH | Tel. : 0911 - 14870374 0 Schleiermacherstr. 2 | Fax. : 0911 - 14870374 9 D-90491 Nürnberg | Mobil: 0163 - 49 64 461 Geschäftsführung: Dipl.-Inf.

Client build question
by Hauke Fath (SPG) 20 Mar '24

20 Mar '24

Hi, by way of an introduction: I maintain the x11/x2go-client package on pkgsrc (<https://pkgsrc.se/x11/x2go-client>). The package has a few patches, which you may be interested in. While updating to 4.1.2.3, I stumbled over a build problem: In <https://gitlab.x2go.org/x2go/client/x2goclient/-/commit/fc2db75ab86889cdde6…>, the MAKEOVERRIDES variable is supposedly set to a list of make variables that are safe to propagate to sub-make processes.* I find that this breaks the build, since gmake (v4.4.1 here) interprets the first word ("SHELL") as target, which it cannot find. Coincidentally, the Arch package <https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=x2goclient> also has a sed(1) command that cleans out the lists. What was the motivation of the change? And where does it actually work? Cheerio, Hauke * The *BSD variants are rather pointless, btw, since the rest of the Makefile has non-portable constructs and won't work at least with NetBSD's make(1) -- The ASCII Ribbon Campaign Hauke Fath () No HTML/RTF in email Institut für Nachrichtentechnik /\ No Word docs in email TU Darmstadt Respect for open standards Ruf +49-6151-16-21344 -- The ASCII Ribbon Campaign Hauke Fath () No HTML/RTF in email Institut für Nachrichtentechnik /\ No Word docs in email TU Darmstadt Respect for open standards Ruf +49-6151-16-21344

Bug#850: Better Mouse Pointer Handling for Shadow Sessions

Bug#117: Make Cinnamon selectable
by Mirco Schmidt 30 Jan '24

30 Jan '24

Package: x2goserver Severity: wishlist Hi hi, I tried to start cinnamon with this command: /usr/bin/gnome-session --session cinnamon2d but it fail's! If I set it to: /etc/X11/Xsession it should start the last session which is cinnamon but come's up with a XFCE session... [12:18pm] [12:33pm]sunweaver:mirco, the command launched by X2Go does not accept cmdline parms. Write a shell wrapper on the server and execute that. Note: your wrapper must be in $PATH [12:33pm]mirco:THX made a wrapper like this and placed it in /usr/local/bin: #!/bin/bash /usr/bin/gnome-session --session cinnamon2d [12:37pm]mirco:sadly I end up with a blank screen, beatified by the default debian Desktop background… Which is also my personal one!

Bug#849: No Mouse Pointer in a Fullscreen Shadow Session on MS Windows
by Stefan Baur 30 Jan '24

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 package: nxagent While it is to be expected that you can't see the mouse pointer of the user you're trying to assist, not seeing your own mouse pointer is really quite annoying.

Bug#846: Terminating a Fullscreen Shadow Session on Linux is Clumsy

Bug#1269: X2go server crashes on Ubuntu 16.04 starting at 2018-03-08
by krehberg＠aol.com 30 Jan '24

30 Jan '24

Package: nxagent Version: 3.5.99.15 (From the Official Ubuntu PPA) Hello, X2go server crashes on Ubuntu 16.04 starting at 2018-03-08. I am using Windows 10 as the client. It happens most often when moving the window from one display screen to a second one. It also happens after a short time online, usually fewer than 5 minutes. Perhaps a recent Windows 10 update may have caused this since that's the only thing I have changed on these systems. I am also mounting my Windows 10 drive through the X2go client. Sound is disabled. I'm pretty sure nxagent was updated on March 8 to this version: NXAGENT - Version 3.5.99.15 Here is what I see in the kernel log (dmesg): [ 194.802419] nxagent[3035]: segfault at 0 ip 0000559edeb9c5fb sp 00007ffcbebf71c0 error 4 in nxagent[559edead1000+432000] [ 9277.059883] nxagent[23367]: segfault at 0 ip 0000562497ecb5fb sp 00007ffcd24230b0 error 4 in nxagent[562497e00000+432000] [ 9319.625785] nxagent[24275]: segfault at 0 ip 0000557f7e17f5fb sp 00007ffd7cbda740 error 4 in nxagent[557f7e0b4000+432000] [ 9696.220810] nxagent[25857]: segfault at 0 ip 00005607d52375fb sp 00007ffc87afbb40 error 4 in nxagent[5607d516c000+432000] [ 9750.298187] nxagent[26894]: segfault at 0 ip 000055c8f5dbd5fb sp 00007ffef53ee0e0 error 4 in nxagent[55c8f5cf2000+432000] I don't see anything remarkable on the Windows 10 side. Thank you for your efforts. Kris Rehberg

Bug#879: CVE backports incomplete or wrong
by Ulrich Sibiller 30 Jan '24

30 Jan '24

Package: nx-libs Recently a lot of CVE fixes have been added to nx-libs. E.g. debian/patches/1027-render-check-request-size-before-reading-it-CVE.full.patch and debian/patches/1028-render-unvalidated-lengths-in-Render-extn.-swap.full.patch add missing checks to nx-X11/programs/Xserver/render/render.c. However, there's a file called nx-X11/programs/Xserver/hw/nxagent/NXrender.c which is derived from render.c and in that file those checks are missing, too. (I suspect the original render/render.c is not used at all in favour of hw/nxagent/NXrender.c but I am not 100% sure here.) If render.c is used a all (I am not sure) the patches should be extended to also fix NXrender.c. If render.c is not used it should be removed and the patches should be applied to NXrender.c instead. There might be more cases like this, I only picked this one as an example.
