Hi,

I just spent a bit of time grepping through the code of the nxagent I
have on my servers.

Apparently the keyboard file is some trick that was added as a patch in
FreeNX's code to dump the keyboard configuration received by the agent,
so not really that useful. (Attached the patch in question to this mail
if that helps).

So then I played a bit with setxkbmap on my X2go server to check exactly
what should be set to:
 1) Fix the alt-gr issue
 2) Make my weird keyboard layouts work (-layout ch -variant fr and
-layout us and -variant altgr-intl)

Each time playing with setxkbmap and re-checking "xprop -root" to look
at the result.

First test with my laptop using the US international + alt-gr dead keys
layout (-layout us -variant altgr-intl):
 - Initial value on x2go is: "xfree86", "pc105", "us", "", "". Layout is
regular US and alt-gr is broken (acts like ALT is pressed all the time)
 - setxkbmap -layout us -variant altgr-intl: Dead keys work now but
alt-gr is still acting like it's pressed all the time.
 - setxkbmap -rules xfree86: Fixes the alt-gr issue giving me the right
layout and behaviour.

"xfree86", "pc105", "us", "altgr-intl", "" is the end working result.
This can be achieved by running: setxkbmap -layout us -variant
altgr-intl -rules xfree86

I then tried again with the Swiss French layout, using:
setxkbmap -layout ch -variant fr -rules xfree86

Which gave a similar result. Adding that line in my .bashrc solved
pretty much all my layout issues.

Hope it helps!



Hope it helps!
