Bug#1519: x2go is aborted: unable to open display
by simona bellavista 11 Jan '21

11 Jan '21

Package: X2Go Client Version: 4.1.2.2 I work on OSX client. I try to connect to a remote server, and the connection fails. I was able to connect until 3 days ago, I did not change anything that I can remember. I get the following error message: Error: Aborting session with 'Unable to open display 'nx/nx,options=/tmp/.x2go-user/C-user-173-1610379165_stDXFCE_dp32/options:173''. Session: Aborting session at 'Mon Jan 11 16:33:18 2021'. Session: Session aborted at 'Mon Jan 11 16:33:18 2021'. Loop: WARNING! Signals were not blocked in process with pid '30901'. Warning: Signals were not blocked in process with pid '30901'.

Bug#1495: x2goclient resumes existing session with wrong X-Server options
by Maarten Boekhold 09 Dec '20

09 Dec '20

Package: x2goclient Version: 4.1.2.2 Windows 10, x2goclient 4.1.2.2 When resuming a "paused" x2Go session, x2goclient is using the wrong X-Server settings. I have configured my x2goclient with the following settings for X.Org Server settings: **X.Org Server settings** [X] use custom X-Server Executable: C:/Program Files (x86)/x2goclient/VcXsrv/vcxsrv.exe [ ] start X-Server on X2Go Client start Window mode: -screen 0 %wx%h -notrayicon -clipboard -keyhook \ -nowinkill -nopn -silent-dup-error Fullscreen mode: -fullscreen -notrayicon -clipboard -keyhook \ -nowinkill -nopn -silent-dup-error Single application: -multiwindow -notrayicon -clipboard \ -keyhook -nowinkill -nopn -silent-dup-error Whole display: -nodecoration -notrayicon -clipboard -keyhook \ -nopn -silent-dup-error -screen 0 @ My x2goclient session is configured as: **Session preferences: Input/Output** [ ] Fullscreen [ ] Custom Width (greyed out 3696) Height (greyed out 2160) [X] Use whole display [ ] Maximum available Display: 2 When I start a new x2Go session, it correctly runs the X-Server with the "Whole display" command (as per Windows Task Manager): "C:\Program Files (x86)\x2goclient\VcXsrv\vcxsrv.exe" \ -nodecoration -notrayicon -clipboard -keyhook -nowinkill \ -nopn -silent-dup-error screen 0 @2 :0 But if I then "pause" this session and reconnect, x2goclient uses the "Window mode" command line options instead: "C:\Program Files (x86)\x2goclient\VcXsrv\vcxsrv.exe" \ -screen 3696x2160 -notrayicon -clipboard -keyhook \ -nowinkill -nopn -silent-dup-error :0 I suspect this has something to do with the code around line 4442 in onmainwindow.cpp, but I've not been able to figure out the exact details yet.

Bug#1510: nx defaults for packing are always overridden
by Ulrich Sibiller 01 Dec '20

01 Dec '20

Package: x2goclient Version: 4.1.2.2 NX has built-in defaults for the image compression parameter which are based on the selected connection speed. x2goclient does not honor these defaults but always sets the compression method explicitly. This means users who want to improve their performance by lowering the link speed setting (e.g. from wan to adsl) will not get the image compression nx thinks is best for the link speed but the one that is pre-defined by x2goclient, which is always 16m-jpeg-9. So they will not benefit from the best performance. See https://github.com/ArcticaProject/nx-libs/issues/802 for a description of the defaults: ----------------------------------------------- There are some high level compression modes, too, that will map to one from the list above: - "lossy" will map to "16m-jpeg" - "lossless" will map to "16m-rle-9" for link=lan and "16m-bitmap" for all other link types. - "adaptive" will choose lossy or lossless, depending on the characteristics of the image If no pack method is provided it will be set automatically from the link parameter: - modem: adaptive-3 - isdn: adaptive-5 - adsl: adaptive-7 - wan: adaptive-9 - lan: adaptive-9 -----------------------------------------------

Bug#1509: Unsupported pack methods
by Ulrich Sibiller 01 Dec '20

01 Dec '20

Package: x2goclient Version: 4.1.2.2 In the session configuration users can choose compressions methods with "rdp" and "rfb" in the name. Both compression methods are not supported by nx-libs since version 3.0.x and will lead to no image packing being used at all. From the session log: ... Loop: PANIC! Can't identify pack method for string '16m-rdp-compressed'. Error: Can't identify pack method for string '16m-rdp-compressed' ... Info: Using pack method 'none' with session 'unix-kde-depth_32'. ... This is absolutely counter-intuitive. Users selecting a compression method on purpose surely do not want to end up with no image compression at all. So they should be dropped completely.

Bug#1508: non Latin 1 passwords are rejected
by Sylvain Cuaz 27 Nov '20

27 Nov '20

Package: x2goclient Version: 4.1.2.2 Passwords with accents are rejected by x2goclient while working fine directly with ssh. Client OS Ubuntu 20.04.1 LTS with libssh 0.9.3-2ubuntu2.1 Server OS Ubuntu 16.04.6 LTS According to the documentation of ssh_userauth_password(), passwords should be passed as UTF-8. But sshmasterconnection.cpp passes auth_password.toLatin1(). I think just changing to auth_password.toUtf8() should suffice. Same thing goes for ssh_userauth_kbdint_setanswer() and maybe other calls. https://api.libssh.org/stable/group__libssh__auth.html#ga50c0c150f8c4703e7e… https://api.libssh.org/stable/group__libssh__auth.html#ga75e44b1f27059a0008…

Bug#1503: x2goagent coredump on fedora 33
by Gianluca Parmiggiani 06 Nov '20

06 Nov '20

Package: x2goagent Version: 4.1.0.3 After upgrading from fedora workstation 32 to fedora workstation 33 I'm no longer able to use x2go for remote work (I asked a linux workstation and configured it myself). X2go has been running fine since f31. Often after a reboot I can still use x2go for some minutes then it starts to close unexpectedly even after a few seconds or when opening new windows after session creation.
