I can't imagine why it would do that... I'll look in to it asap!

Ok I figured it out. For some reason the ~/.Xauthority on my notebook was owned by root. Changed it back to my own and problem went away. For those wondering how to run a different app. You can do X-forwarding from the commandline as well:

- Open xterm
- type (replace 'username' and 'host' with the remote username and ip address)

Code:

  ssh -X username@host

(fill in password)
type name of the app

Code:

  inkscape

I wonder if these things are possible with X-forwarding:

- use maemos on screen keyboard. I have an n800 so I can't use the hardware keyboard.
- use a local or remote GTK theme
- hear sound
- maximize windows without relying on per application 'maximize' buttons
<edit> Found a way to do this, be it a bit hackish:

Code:

wmctrl -r :ACTIVE: -b toggle,fullscreen

</edit>

Also it doesn't seem much faster than Tightvnc over ssh using some compresion and optimalization (though only minimal, you can go quite far with compression on tightvnc) like I described on the wiki.

v0.3 doesn't work for me:

~ $ airx
Woo
Traceback (most recent call last):
File "/usr/bin/airx", line 152, in <module>
execfile("/home/user/airxhost.py")
IOError: [Errno 2] No such file or directory: '/home/user/airxhost.py'

v0.1 was ok. Uninstalling it before installing v0.3 doesn't fix problem.

That means AirX could not create a file in your home directory.

Are you running it as root or user? Or, have you ever accessed your tablet via ssh? Permissions on that folder may have been inadvertently changed whilst doing something.

AirX checks for that file at every start-up, and if it does not exist, it attempts to create a blank one. Failing that, it gives you that error.

I had the same problem. Although, I was able to do "touch /home/user/airxhost.py" as the tablet default user fine and the application started up.

Is pexpect installed?

I had previously worked this one out in a weird way...

Thanks, Qwerty. I'll have to look into running a touch before letting AirX just die...

VNC is nice on occasion, of course! (Many thanks for that guide, too.)

A VNC session is not as secure as (most) ssh sessions, right? But, then it suggests running VNC through SSH, which is a little redundant when all you need is SSH....

I will do my best to add a full screen option in the next release, too
