Edit: OK, I no longer think the problem is with X. See the post below for more info.

I just finished reinstalling linux on my Toshiba Satellite 1130/1135 laptop and reconfigured X (I didn't save my old xorg.conf file). After I did this, my "alt" key won't work after I boot up X (though I can still hit ctrl+alt+F1 to drop to the VC and alt+Fx to switch between VCs). This is very annoying as I have a lot of keyboard shortcuts that depend on the "alt" key, and I don't like having to use the mouse so much. Any help would be much appreciated. (Also, FYI, the 1130/1135 has a really strange keyboard, though I don't think this is the problem, since everything worked just fine on my previous installation).

Here is the part of my xorg.conf that deals with the keyboard.

Section "InputDevice"

Identifier "Keyboard1"
Driver "kbd"
Option "AutoRepeat" "500 30"
Option "XkbRules" "xfree86" #this was originally "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"

EndSection

Just some more information. I no longer believe that the problem is X (I can use the alt key shortcuts in FireFox and urxvt). I now think the problem is with Fluxbox. So, is there anything wrong that you guys can see in my ~/.fluxbox/keys file?

Mod1 Tab :NextWindow
Mod1 Shift Tab :PrevWindow
Mod1 Left :PrevWorkspace
Mod1 Right :NextWorkspace
Mod1 F1 :ExecCommand urxvt
Mod1 F2 :ExecCommand /opt/mozilla/bin/firefox
Mod1 F4 :Close
Control Mod1 Up :MoveUp 10
Control Mod1 Down :MoveDown 10
Control Mod1 Left :MoveLeft 10
Control Mod1 Right :MoveRight 10
Mod4 m :RootMenu
Mod4 r :ExecCommand fbrun

(all the Move* commands work just fine, but nothing else does)
