Linux x64 keyboard keys not being read right

[kitchen_ace]

Hi, very amazing thing you've created here.

I'm running it on Arch Linux 64-bit, and some keyboard keys aren't being read properly in the Settings/Controls menu. For example, the up, down, and right arrow keys all produce "0x00" while the left arrow key produces "Alt". Alt itself produces "Enter"... the problem with this is that several keys end up doing the same thing, like the case with the arrow keys all making 0x00. Also I can't press up or down to go through previous console commands, though that's far less important.

I'm using a thinkpad X230 in case that matters.

edit: Using the 32 bit binary produces the same results

i did not found a sollutions on the tdm forums. But on the ubuntu forums on D3, i found a simular problem at the following topic:

Good find, thanks. Looks like the fix offered there is pretty hacky though. I'll see if I can make something a little nicer work.

I looked at dhewm3 which doesn't have this problem, but that's most likely because it's using SDL.

Excuse me. But There are some topic about this.
(Did not remember them at the time, when i was writing my first post in this topic.)
Take a look at: the forums search function that points to the mentioned topics

Phew, key mapping on Linux looks quite broken in the code. Doom3 is using a very limited mapping table on possibly the wrong input. I added a new mapper for standard special keys that should at least improve the situation, starting from 2.08. In the long term, we may need to look into a rewrite, possibly using a sensible input library.

If you're looking for a workaround, I use evrouter for my mouse buttons which I described here (I'd think you could use it the same way for the arrow keys):
