Xpra: Ticket #180: some keys are not forwarded

Hi Antoine,

Just reporting a minor issue in hope that you could advise:

I've noticed two keys on my keyboard that do not work through xpra in remote applications: '/' and '*' but only those on right hand side next to "Num Lock". I use the very same layout on local and remote machine:

rules: evdev model: pc101 layout: us

Any ideas?

Thank you.

There are a number of similar keyboard bugs: #91, #117, #108, #109, #86

The key one is #149

Fixing all those is not going to be easy.. Feel free to add more information here (as per the other bugs: setxkbmap and xmodmap output, etc)

Sorry for incomplete information.

I run xpra with --debug=all and found something interesting in log on server side:

Similarly KP_Multiply, KP_Subtract and KP_Add were affected.

Somehow upgrading package "keyboard-configuration" 1.80 --> 1.82 fixed this problem on Debian.

I'm not sure about neither what was the root cause for this nor how did the solution worked.

(At least we have some information for the record).

Probably this ticket can be closed now.

Thanks.

Sounds like you upgraded to a version of setxkbmap that supports -query?

Did you not see the big warning when you started the client before you upgraded keyboard-configuration?

the server will try to guess your keyboard mapping, which works reasonably well in most cases
however, upgrading 'setxkbmap' to a version that supports the '-query' parameter is preferred

Could be but I reviewed keyboard-configuration changelog and didn't find anything relevant...

That's a tricky part: I already had keyboard-configuration-1.82 on client. When I started to troubleshoot I first run a local server which forwarded problematic keys successfully. This gave me suspicion that something must be slightly different between client and server and it wasn't long until I found the difference responsible.

Thanks for your comments.

No, this is not the case: on Debian /usr/bin/setxkbmap provided by package 'x11-xkb-utils'. It didn't change. I don't know how 'keyboard-configuration' could be relevant but that was the only package I updated.
