Bug#789: I reproduced it
by Michael DePaulo 05 Mar '15

05 Mar '15

I reproduced this bug on my system: X2Go Client for Windows 4.0.3.2-20150301-debug Windows 10 64-bit (build 9926 with latest patches) I've CC'd the developer who added Windows Kerberos support, Alex. I've attached the "Sessions" registry key before and after. The test session I created, uss-phoenix, was clearly deleted. HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\Sessions\uss-phoenix\ However, there is no indication in the debug log (attached) that the Sessions key or its subkey was touched. I'll take a look at the x2goclient source code to figure out what is going on. -Mike#2

Bug#803: Numlock-state resets on first keypress after resume/start
by Florian Wicke - Hetzner Online AG 04 Mar '15

04 Mar '15

Package: x2goserver Version: 4.0.1.18-0x2go1+git20141006.949+jessie.main.1 Unfortunately i am NOT able to "synchronize" the local numlock status to the client session in any way or even CHANGE the numlock status of the usersession. Clients running as thinclients with "x2gothinclient-displaymanager" from heuler and everything is up2date with the "heuler" branch. Desktop is XFCE but the same issue appears with KDE or LXDE. Numlock-state saving is disabled - but should not be executed on resume as far as i understand - just on starting a new session. Even replacing "x2gosetkeyboard" with an empty "exit 0"-script does not change this behavier (my first guess was the setxkbd resetting the numlock state on keypress). Any ideas how i can debug this further? Steps to reproduce: 1. turn numlock off and verify with 'numlockx status' in the user session 2. start terminal with 'numlockx status'-loop like: while :; do sleep 1; numockx status; done 3. have a post-resume.d-script present with 'numlockx on'-command (with correct DISPLAY set) 4. suspend session (5. turn local numlock on) 6. resume session 7. see 'numlockx status' transists from "off" to "on" as executed from the post-resume.d-script but now the unexpected problem: 8. press ANY key on the keyboard 9. see 'numlockx status' transists to "off" again no matter what your local keyboard is set. Time between #7 and #8 does not matter - first keypress after resume resets numlock.

Bug#789: Kerberos 5 auth. reset putty sessions list
by Earl Tom 04 Mar '15

04 Mar '15

I think this is a duplicate of bug #625. There's a snippet of code attached to that bug that looks suspicious. I think it's trying to delete one session but ends up deleting them all. This hits me, too, so it would be nice to have it fixed. My workaround is that I've exported a .reg file of the sessions and import that after starting x2goclient. Thanks, -- Earl

Bug#704: Desktop sharing works well after installing x2godesktopsharing version 3.1.1.2 and x2goserver version 4.0.1.19
by Alexey Murz Korepov 03 Mar '15

Desktop sharing works well after installing x2godesktopsharing version 3.1.1.2 and x2goserver version 4.0.1.19 But in PPA https://launchpad.net/~x2go/+archive/ubuntu/stable available only 3.1.1.1 version, with this version Desktop sharing not working - always receive "Access denied from user" Can you update x2godesktopsharing package from 3.1.1.1 to 3.1.1.2 on https://launchpad.net/~x2go/+archive/ubuntu/stable ? Thanks! -- Best regards, Alexey Murz Korepov. Email, Jabber: murznn(a)gmail.com

Bug#775: About X servers
by Michael DePaulo 03 Mar '15

03 Mar '15

Hi Samo, Sorry to hear that you are running into these issues. The situation with X2Go Client for Windows and X servers is this: We support using an external X server, but we both bundle and maintain VcXsrv on a 1.15.2.x branch.[1] We intend to make any source code changes necessary to VcXsrv to fix integration issues with X2Go. In fact, we already made one X2Go integration change (bug #594, winmultiwindow.patch). However, those changes are slow to be made because we have few developers who spend pro bono time maintaining X2Go Client for Windows. Patches are welcome. These bugs/issues can also be fixed on contract. So in conclusion, we do intend to fix these issues, regardless of what piece of software is at fault. However, we cannot give an ETA. -Mike#2 [1] The VcXsrv 1.15.x branch we are maintaining is here: https://sourceforge.net/u/mikedep333/vcxsrv/ci/xp-1.15.2.x-x2gochanges/tree/ We may rebase to a newer VcXsrv branch soon.

Bug#775: desktop sharing full screen usability issues
by Samo Dadela 03 Mar '15

03 Mar '15

Package: x2goclient (Windows 7 x86) Version: 4.0.3.0 [ Server: FC21 x64 ] Hi, Found x2go recently as an alternative to NoMachine NX (which is not usable for programming since jpg compression makes terminal windows unusable... and there are other issues like random hangups, etc). My use case is as follows: - connect to the existing desktop session in full screen (aka desktop sharing in x2go) - need grab keyboard when connected (example: alt-tab must switch between windows in the session, not between Windows on the client, ctrl-alt-left must switch to another desktop on the server, etc..) - be able to enter/exit fullscreen mode somehow - by using a hotkey, for example - be able to see the mouse cursor In other words... behave as though I was connected to the real desktop on the server. What I tried: 1) Specifying fullscreen in the Session preferences What happens: - I get a full screen windows, - there is no mouse cursor (the mouse works - I see the windows receiving focus) - When using alt-tab it switches between windows on the client (other combinations are also intercepted by Windows, not the desktop) 2) To make alt-tab work, I tried the instruction at http://www.terheyden.com/blog/?p=202 - (x2go client - getting Alt+Tab to work) by specifying -rootless and -keyhook (don't forget to change the path to VcXsrv.exe otherwise you can't use x2go client anymore without deleting the registry keys; this is an already know bug). What happens: - alt-tab works, other keys work (like ctrl-alt-left to switch desktops) - still no mouse cursor (even tried -swcursor but it doesn't help) - can't enter/exit full screen... it seems that the combinations ctrl-alt-f are now passed to the server 3) BTW, tried pyhoca too - but it complains that it needs server 4.1 for desktop sharing ;( Maybe the above (apart from the mouse cursor) are not bugs but just the way things work... What I would like: - changing x2goclient on Windows so that such functionality can be achieved by a few mouse clicks (add a grab keyboard option, define 'exit x2go' hotkey,...) or... if this is too much work - some instruction on how to achieve the functionality mentioned above (add it to the FAQ?) Next I saw some post claiming success using Xming... I'll give that a shot, but wouldn't it be better if x2go handled it by itself? Best regards, Samo

Bug#510: ctrl-alt-f crashes x2go windows 7 client
by Rob MacLachlan 03 Mar '15

03 Mar '15

Package: x2go I'm running x2go win32 client, version 4.0.2.0. Similar behavior happened in 4.0.1.2. This with remote host running x2goversion x2goagent: 3.5.0.21 x2goserver: 4.0.1.13 x2goserver-extensions: 4.0.1.13 x2goserver-fmbindings: 4.0.1.13 x2goserver-xsession: 4.0.1.13 # Springdale linux 6.5 uname -a inux lov3.int.autonlab.org 2.6.32-431.17.1.el6.x86_64 #1 SMP Wed May 7 21:28:34 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux Whenever I type ctrl-alt-f, bad things happen. I understand this is supposed to switch full screen mode in the default shortcuts, but it doesn't actually successfully create a working full-screen setup (no keystrokes are recognized), and anyway the reason I'm typing ctrl-alt-f is to do "forward form" in EMACS. I would be fine with just changing the default shortcuts, but I haven't been able to figure out how to do that either. The wiki instructions on changing the shortcuts don't seem to work (maybe obsolete file location?). Rob

Bug#510: Dup of #496, shortcut configuration is #741
by Michael DePaulo 03 Mar '15

03 Mar '15

Hi Rob, Sorry to hear that you ran into this bug. The crashing bug is #496. I will mark it as a dup. I wish I could tell you an ETA on when it will be fixed. The fact that you cannot change the shortcuts is #741. #741 will be fixed as part of nx-libs (which includes the x2goagent package) 3.5.0.29. That new version of nx-libs should be out within days. -Mike#2

Bug#765: Workaround. And was this on Windows?
by Michael DePaulo 03 Mar '15

03 Mar '15

Hi Promox, Sorry to hear that you ran into this bug. Were you using X2Go Client for Windows? I reproduced it yesterday with X2Go Client for Windows 4.0.3.2-20150301. It appears that this occurs when the server does not have an ecdsa 256-bit key. Some Linux distros generate one by default, others do not. The workaround is to generate such a key: sudo ssh-keygen -f /etc/ssh/ssh_host_ecdsa_key -N '' -t ecdsa -b 256 I think this is a bug in terms of how x2goclient uses libssh -Mike#2
