Keymap issues with NX from Mac OS X Lion [duplicate]

I tried to answer the question from Mark:

Keymap issues with NX from Mac OS X Lion to Ubuntu

However, it is locked so I figured I would post a new question / answer.

I have been trying to answer this for a few days now because I have no issues when connecting through开发者_开发技巧 NX Client (technically OpenNX) to FreeNX server from an iMac (with Lion), but if I try to connect with a Macbook Pro I get horrible keyboard binding issues.

I had the same issue (I'am on a Macbook Air with OSX 10.7 Lion) and reverting back to 0.16.0.648 fixed the problem for me too.

I'm on a Macbook Air with OSX 10.8.4. I've tried release 648, 649, and 725 of OpenNX to connect to Ubuntu 13.04. Each didn't work out of the box and even with the above trick of editing my profile's cfg, my keyboard mapping still isn't right. (The sshlog shows '--keyboard="empty/empty"')

Once connected, in all of these cases, the 'd' key minimizes all open windows, the up arrow key maximizes the current window, and the down key restores it to its original size. My point is that with all of the above attempts changing something on the Mac OpenNX client, I'm starting to think the problem is something Canonical has done with Ubuntu 13.04 and/or FreeNX. That latter doesn't look like its been updated since I had to install it from the 12.xx ppa.

As a further datapoint, even X2Go connections exhibit the exact same behavior when using the Gnome desktop. In the X2Go case, the client dialog shows using a pc105/us keyboard.

I hope this gives others something to go on. I couldn't add this as a comment so had to do it as an answer, sorry.

I had this problem with 10.7.5, the fix was to install XQuartz instead of the native X server. Well, mostly fix. The CAPS LOCK is inverted, that is, it's all caps when it's off and normal when it's on but otherwise the keyboard works with XQuartz. Installation is easy and it didn't break anything else on the Mac. Although what is working even better for me was to load Ubuntu on the Mac, right now I have it setup dual-boot.

The fix that is working for me is to go into:

~/.nx/config/HOST.nxs

and change:

<option key="Current keyboard" value="false"/>
<option key="Custom keyboard layout" value="empty"/>
<option key="Grab keyboard" value="false"/>

I have tried this on three NX Servers and all are fixed. Hope it helps or gets you closer. Always check in the ~/.nx/temp/ for the sshlog and see if --keyboard="empty/empty" instead of "pc105/en" because the Mac is really pc104.
