Description Peter McPherson 2010-09-09 14:30:34 UTC

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.9.2.8) Gecko/20100723 SUSE/3.6.8-0.1.1 Firefox/3.6.8

After updating to Linux 2.6.34.4-0.1 my desktop mouse and keyboard do not respond to the first click/character. This happens if I leave them idle for about 3 seconds. It makes it very difficult to work on text etc. If I transfer them to my second (not updated) PC, everything is fine.


Reproducible: Always

I would like to confirm this problem.
I encountered it on two laptops both using a Logitech Alto laptop stand with integrated USB hub and wireless keyboard.
The non-wireless USB mouse connected to the integrated hub worked just fine but the keyboards missed the first (couple) of key presses each time after a short idle time (few secs).

I reverted to the Linux 2.6.34-12 kernel and everything was fine again.

I also noticed the following:
- the problem only occurred inside the KDE4 session; when logged out typing in the password in the login screen worked without problems; also when switched to a text console (Ctrl+Alt+F2 f.i.) there did not seem be a problem (although the keyboard response seemed a little sluggish there)
