AltGr-key on debian-ppc working!
 

I finally got the Alt-Gr key working on debian-ppc dist after months of copying and pasting the @-character!!! I had to edit the very core of X keyboard geometry but I did it! :D :D :D

Howto
 

I have just installed debian sarge and i am having the same problem. i am using kde right now and my 'Alt Gr' key is totally ignored. I know i have my xconfiguration correctly because i use a xfree86config file which was backed up from a previous installation of woody (i think). but this key doesn't work
How did you do to make it work.
thank you

Well, it's pretty simple really once you do it.

The main problem I was facing was that the damn box wouldn't accept my apple-key as a key with two states(pressed or unpressed). When using xev, pressing and holding shift for instance would give a state 0x1, and when releasing state 0x0. Anyway, the apple key didn't have states, so when pressing and holding it, it behaved like I was pressing it continuously (like holding down a character key).

The way to solve this problem is make xkb believe that the apple key is actually an altgr key. I think you should edit /etc/X11/xkb/geometry/machintosh and look for a place where it says:

top= 77;
keys { { <LCTL>, "LCTL" }, { <LALT>, "LALT" },
{ <OPT>, "OPT" },
{ <SPCE>, "SPCE" },
{ <RMTA>, "RMTA" },
{ <RALT>, "RALT" }, { <RCTL>, "RCTL" }

Now replace OPT(I think it says OPT, mayby it says LMTA I can't remember) with ALGR both places and try out xev - your key should now be with pressed/unpressed states.(Although strangely enough instead of giving 0x0 for unpressed, it gives 0x2000 - but who cares, it works!)

Now what remains is to bind Mode_Switch to your key using xmodmap, and making it load at startup. Reply if you need any help doing this! :)
