Description Alon Bar-Lev 2010-04-28 10:39:24 UTC 
Version:            (using KDE 4.3.5)
OS:                Linux
Installed from:    Gentoo Packages


Please refer to xorg bugzilla [1]

Since upgrade to xorg-x11-7.4, the keyboard stops functioning at random
occasions. (xorg-x11-7.3 worked correctly with the same evdev driver).

<Alt><Ctrl>F1 switches back to console, <Alt><Ctrl>F7 switches back to X.
Console works correctly, only X does not accept anything.

Mouse is working.

xev shows no keyboard activity.

Later, victor found that this is related to kwin grabbing the keyboard and not release it.
killing kwin releases the grab.

Question: What was changed since xorg-7.3 that causes this, or if kwin does something wrong.

Thanks!

as the xorg report mentions alt+tab invocation and window switching has entirely changed with 4.4, please try to upgrade.

also see bug #171685

OK, fixed in 4.4, I had no such issue with 4.4.
