Server not responding

[freeman]

Hi, I do not know where to post this issue sorry if this is already posted.

I recently installed winswitch on a newly installed ubuntu computer.

xpra 0.7.30, nxserver, vnc server, sshserver are all installed

I try to run the the application but nothing works. When I start an application from the applet, I have a notification is says, "server not responding", or "something went wrong".

I tried by hand to run the server, and the command parser but it does not work either.

I checked Xpra and it does work manually.

I do not know what to do or change to make it work

this is the std output from the client, which seems to be the source of the problem.

How did you install it? From source?

Looks like something is going wrong with the python-twisted code (REACTOR, is twisted installed? Is pygtk also installed?

[Antoine Martin]

btw, the "client" is not meant to be used directly as there is no UI to control it. Only "winswitch_applet" and "winswitch_server" are actually useful.

[freeman]

So yes I checked that, and yes pygtk is installed and twisted too

below the log when I try to run gnome-terminal (it seems to try running sub-processes but not have sufficient privileges, is this true?)

[freeman]

apparently it is pointing to the wrong directory for

[EE] 2011/15/11 21:54:12 virt_server_daemonizer.grab_daemon_pid(['/usr/local/lib/winswitch/virt_server_daemonizer'

It is not there but in the python libs, where can I change that?

[Antoine Martin]

I need go back to my original question: how did you install it? from source? from trunk? from packages?
Which version of Ubuntu is this? Is it 32 or 64-bit?

It looks like it is not detecting the path to the location containing the "libexec" directory.
If you find where you installed "virt_server_daemonizer", you should be able to use this workaround:

winswitch_xxxxxx --winswitch_libexec_dir=/path/to/dir

[freeman]

ubuntu maverick 64-bits

I installed it from the package repo.

[Antoine Martin]

Hah, well first Maverick is so broken in so many ways that I would not waste my time on it...
Still, is there anything in /usr/local/lib/winswitch? There should not be, but then why would it select this path if it did not exist!?

[Antoine Martin]

Have you ever attempted an install from source which would conflict with the package?

[freeman]

I totally removed the app, and reinstall (again from the repo).

It finds /usr/local/lib/winswitch and this time has the needed files.

But still could not start the daemon apparently.

(I could not change the distro. Not my choice.)

[Antoine Martin]

FYI: just tested on the closest thing I could find (Lucid 64 bit) and the package installed it correctly here:

/usr/lib/winswitch/virt_server_daemonizer

And /usr/lib/winswitch is the location that is detected during startup.

I don't understand why anything would install in /usr/local - will check the maverick package tomorrow, I am out of time for today sorry!

[freeman]

Thanks a lot

Maybe this will help

[freeman]

and now it points at /usr/lib/winswitch/virt_server_daemonizer (sorry if I badly reported that)

[freeman]

Sorry, I found out what was the problem. Installation was pointing to the wrong python version.

I changed where to point for python and now it seems to work properly.
