severity 492888 grave thanks Package: xserver-xorg-input-kbd Version: 1:1.3.1-1 I can confirm this bug. It is really a boring bug. dmesg is empty, log also. How can I debug this bug ? Raise importance to grave because it completly render keyboard unusable after random time, and destroy completly my X session. Only mouse work, and I need to disconnect using mouse. Thank you Bastien
