Well, I use the laptop keyboard (atkbd0) and either a PS2 keyboard via PS2-USB convertor, or a SUN keyboard via SUN-USB converter (although, the converter mumbles something about PS2) addr 1: EHCI root hub, Intel addr 2: USB2.0 Hub, vendor 0x05e3 addr 3: PS/2 KB & MS, vendor 0x0430 > you should also know that there is a keyboard state synchronization > problem with kbdmux(4) (seems to be related to control/shift/alt keys) > that i can reproduce, but still can not fix :( Hmmm, I had something strange going on with this Sun keyboard. Namely, all KeyPress/KeyRelease events would work like expected, except for the two Meta keys. Pressing them, would do nothing. Releasing them would result in the KeyPress (sic!) event. Then pressing any other key would result in the KeyRelease of the Meta key *and* the KeyPress of the pressed key. I can't reproduce this since I'm no longer using kbdmux(4), but I also changed my xmodmap, so this could be the cause. > > So, are there any users of kbdmux out there?

I think it's because it's not very easy to use. Getting that stupid 'kbdcontrol foo < /dev/whoknowswhatshouldbeplacedhere' right is very tricky.

Good, at least I know the culprit now and my mental sanity is saved :) If you want me to test anything, just shoot. Ulrich Spoerlein -- PGP Key ID: F0DB9F44 Encrypted mail welcome!
