Bug#850: Better Mouse Pointer Handling for Shadow Sessions
by Stefan Baur 30 Jan '24

30 Jan '24

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 package: nxagent severity: wishlist - From a usability/user experience standpoint, it would be nice if: a) one could see the remote mouse pointr on one's own screen when running a shadowed session b) the person sitting at the remote screen could see one's own mouse pointer when running a shadowed session c) there was a way to "latch" the pointers together, so that only one pointer is visible on the screen, and each pointing device input, no matter if made locally or remote, moves this single pointer - -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJVMlAhAAoJEG7d9BjNvlEZdREH/2AfJ4ciAu8rSmDZjrRetbNw 3KjOxBFzW+fAvc9LAN+8dwWQbSFts4NkF7ycYTZR+RyUHwwoUvL5Th/MDAE/Xau/ Li+556zgypyYkB1N253Lv4yEfxybvSmolsM5FPsI0mi5WDVVjtbMjwYCNxQrdrc2 yoAoSahsuc8FCUiwTHpbMMbgXor3hQt77pxHswQ2+rV/v0i+/345uKxRoOQ2XnQl ZVOT5hSRlBs7U+G6zwfGdFDSiPhN0uOqMLUgAiPPOLzMlYAWDyPBfTYhhSf2yGCD WcbyMp1pPFoiTgn9yelKulR25I/gxDT0NduC6ImJNC26jOZ5lMhTnLqrvbkTyM8= =CNAu -----END PGP SIGNATURE-----

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! Thank's in advance Mirco

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

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. This only happens in fullscreen mode and on MS Windows. It seems to be unrelated to Bug #844, as the remedy/workaround with lxappearance doesn't help here. - -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJVMlAeAAoJEG7d9BjNvlEZlnYH/Ay46cwAvzoExhhPtwvdk1P5 qoIBOsjxIwttgF/WlKRsorE6VkZy8eYh5tU78+5yPAOSzJXodvpd7XbZyZ2rLIB2 Z6yeXKZf/V8FfcfR4Wx27FWEMZI+0p4WBsn5jqCrvnPw5JUSou8ARS1XqDH3g8lR JTFa6EySe4o2q9A5qoQ2FTt07ap8K2nZx+sdCMuwFjzjuRfGsUP6kruqxHnqonzi PMoN3coeLJdl3jzxDgqEkyc12vHAANolRBEsr5ynMRWKSSA/xTH/jIKAzx0rJ6R+ EYQ0Dq7VPxHn0r8QymI8HC3CXZm8tQxGQJttelYiv8hYmEAEf6+RTUhhbFlbHwQ= =pCpA -----END PGP SIGNATURE-----

Bug#846: Terminating a Fullscreen Shadow Session on Linux is Clumsy
by Stefan Baur 30 Jan '24

30 Jan '24

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 package: nxagent Currently, there doesn't seem to be a way to cleanly terminate a shadow session running in fullscreen mode. Ctrl-Alt-T doesn't work, Alt-Tab gets sent to the remote end, so one can only run x2goterminatesession on the remote end or kill the x2goclient task on the local side. - -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJVMlARAAoJEG7d9BjNvlEZJI4H+wUoFLOT2hsmp3vv/6ihnqZU jiaJiGTRClrOeVW7q33L9RiTx/2LfbnpSU/q0W7iNsXmq0lV03vxDZphh+6pnW7G mekwBC9+A8uh/ctb7o+0NI4YN0GQXModko8fLQefR75cpTvDBzjuPTTlAAntuH8B LbsBUCSGohqK6xGkEnFhZAA7YHNpFKyuFY1F1gurWa/KU/kNMKG+y0HjFdBe06Y7 sZ28ehp5UuNr/Ak+y/YCbz5iF9XYuV+nuyqLlwrM+n03RGgtjuXooXCp1P7HA/GQ XQT6Iii5g3O8xRmdN9WNo1lsDNcRetQME7k9o7t1cdXYHvsD0FDVWwbk/uWkeBI= =L2jx -----END PGP SIGNATURE-----

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.

Bug#866: Fix compilation errors in nxcomp (nx-libs) when macros TEST/DEBUG/... are defined (developer support)
by Nito Martinez 30 Jan '24

30 Jan '24

Package: nx-libs Version: 3.5.0.28 Description: The attached patch fixes some compilation errors when the following macros are enabled: (TEST/DEBUG/DUMP). See the lines: #undef TEST #undef DEBUG ... and the conditinal ifdefs #ifdef TEST #ifdef DEBUG ... which are normally not compiled. During debugging and testing when these macros gets activated, there are some compilation errors, which need to be manually fixed each time the Macros are enabled. This patch tries to leverage that error. The patch does not affect code outside of those ifdef, and only provides developer support. Regards, Nito

Bug#865: New API call for nxcom (nx-libs) NXTransCleanupForReconnect
by Nito Martinez 30 Jan '24

30 Jan '24

Package: nx-libs Version: 3.5.0.28 Description: The following patch includes support for a new API call NXTransCleanupForReconnect, which basically clears the state of nxcomp proxy side (modified nxproxy), so that a reconnection is possible. Rationale: Usually nxproxy clears the status of the connection by doing an exit and launching a new nxproxy. This strategy does not work for applications in IOS which do not allow forking. Special care has been taking to not modify any of the other nxcomp code. Regards, Nito
