I just switched to Fedora and it appears I haven't been able to escape an issue my presious install had.
After using my builtin keyboard (on a laptop) for some time the keyboard will suddently become seemingly unresponsive. I've discovered what's happening is that X is just taking a long time to register the keys (though they repeat at the normal rate). When I plug in a USB keyboard I don't have these issues on the new keyboard, but the builtin keyboard continues not to function.
Using showkey I determined that the key events where still being registered by the kernel. Checking xev shows that X is taking a long itme (~1-2s) to register to keys. Text terminals also don't experience this issue, so I'm pretty sure the problem is with X and it's handling of keyboards.
If I use an external keyboard long enough the problem can somehow switch keyboards so that my external keyboard no longer works, but my builtin one does.
I'm using a relatively fresh install of Fedora 17 with 3.5.1-1.fc17.x86_64
My xorg.conf is:
The autogenerated 00-system-setup-keyboard.conf is currently
Option "XkbModel" "pc105+inet"
Option "XkbLayout" "us"
# Option "XkbVariant" "(null)"
Option "XkbOptions" "terminate:ctrl_alt_bksp,"
Any help would be greatly appreciated. This problem is terribly frusturating.
Update: xev reporst this the first time I hit a key on my builtin keyboard since starting it:
MappingNotify event, serial 27, synthetic NO, window 0x0,
request MappingKeyboard, first_keycode 8, count 248
