Hello,
I was asked by Greg Kroah-Hartman to send this email to the mailing list
regarding USB keyboards on LG laptops no longer functioning after Linux
3.9. Below is the text from the bug report i left at (
https://bugzilla.kernel.org/show_bug.cgi?id=93541 ).
----------------------------------
Starting with Linux 3.9, the internal USB keyboard in my LG laptop (LG
R1 model LGW4) stopped functioning in all linux distributions i've tried.
I had spoken to a few guys in the kernel irc channel and they told me
that i should point out the keyboard is found in the attached dmesg log
file on line:
[ 5.516045] input: AT Translated Set 2 keyboard as
/devices/platform/i8042/serio0/input/input4
I had submitted the bug to ubuntu's launchpad bug service and they told
me that i should take the bug upstream (
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1287325 ) and
mentioned the following (comment 26).
"It appears the keyboard is not recognized in 13.04, but it is in 13.10.
... It may be the bug is caused by the fact that the keyboard now being
recognized in 13.10 and another code path is being used."
Other LG laptop users have also encountered the same problems (

http://stevesubuntutweaks.blogspot.no/2013/10/laptop-keyboard-stopped-working-after.html
) and the solution that i currently use is to set "i8042.dumbkbd=1" in
the grub commandline to get it running.

Kind Regards,
Yousuf Philips
