Comment 3 for bug 186264

Thank you for your bug report. However, we need some more information before we can pass this on to the developers.
Could you please attach the results of the following commands:
cat /proc/version_signature > ~/version_signature
uname -a > ~/uname-a
sudo lspci -vvnn > ~/lspci-vvnn
lsusb -v > ~/lsusb-v

Please create the following files immediately after you've logged in:
dmesg > ~/dmesg_boot
cp /var/log/Xorg.0.log ~/Xorg.0.log
Try to replug the keyboard or access a terminal at your computer using VPN, SSH or similar.
Now create the following files:
dmesg > ~/dmesg
diff -ns ~/dmesg_boot ~/dmesg > ~/dmesg_diff
cp /var/log/Xorg.0.log ~/Xorg.0.log_tmp
diff -ns ~/Xorg.0.log ~/Xorg.0.log_tmp > ~/Xorg.0.log_diff

Please add all files you've got this way(you can use an archive). They are all located in your home directory(that's what the ~ is for).
