keystrokes missing with VirtualBox

[Hugo Ideler]

Laptop Setup:

Host: Ubuntu Linux Gutsy

Guest: WinXP SP2

When I run VirtualBox I noticed that some keystrokes get lost. I tested this with typing in a terminal window with VirtualBox running and not running, but it happens everywhere. It occurs in the Virtualbox window (so in the guest), but also in all my linux Apps running.

Interestingly, when I pause my guest OS (Host+P), the problems go away.

I also noticed that my synaptics touchpad misses strokes with my finger under the same conditions. They also get lost and not delayed. With an usb mouse no such problem is noticed.

I don't think I had this problem right away. But I can't pinpoint when it started...

I tried to relate it CPU, but the problems do not exist with a "find /". Then no input gets lost. Also relating it to memory usage does not make sence, since then pausing VirtualBox would not help.

To be correct, I already disabled the synaptics pad and now ony use my touchpad via the generic mouse input from /dev/input/mice.

I use GNOME. I tried killing xbindkeys but that didn't help either. in `xev' it shows keys getting missed. I will try in KDE if that helps.

This problem has disappeared as far as I can see with 1.6.2. Good job.
