Laptop Keyboard not working at all after boot

[Underlien]

Hi

I have used ubuntu since 8.10 on my LG S900 laptop.

Back then, i had to add the line "i8042.nopnp=1 i8042.dumbkbd=1" to "Menu.lst to make the keyboard work once grub loaded the OS.

This has worked until i upgraded to 9.10 64bit.

Now i can't get it to work anymore, so i have to use a external USB keyboard to log in and actually use my computer.

The built-in touchpad works just fine.

Any idea's how i can get it to work again?

Help is greatly appreciated.

My guess is that you need to configure it as a module now. Try creating a new file /etc/modprobe.d/i8042 with the following contents:

options i8042 nopnp=1 dumbkbd=1Then reload the i8042 module with:

$ sudo modprobe -r i8042
$ sudo modprobe i8042If that doesn't work, tell me what "uname -r" gives you and attach the output of dmesg so I can see if something recently changed in the kernel source.

Hi
Thanks alot for the suggestion.

When typing in the command i get this:
FATAL: Module i8042 not found.

I'm not so hardcore in the arts of linux, so im not sure what you want me to do, can you explain it further please?

[kbielefe]

You did it right. That means exactly what it says. No module by that name, could be for any number of reasons, but it's mostly because my hoping for the best case scenario didn't work out. Attach the output of dmesg and I'll look into it in more depth when I get home from work.

[Underlien]

I hope this is the stuff you need, got it from dmesg.conf:

# dmesg - save kernel messages
#
# This task saves the initial kernel message log.

description "save kernel messages"

start on runlevel [2345]

task
script
savelog -q -p -c 5 /var/log/dmesg
dmesg -s 524288 > /var/log/dmesg
chgrp adm /var/log/dmesg
end script

Actually, I need the output of the dmesg command:

$ dmesg | gzip > dmesg.gz and attach the dmesg.gz file.

[Underlien]

dmesg.gz attached :-)

[kbielefe]

Thanks. For good measure, can you also attach your /etc/grub/menu.lst?

Also, try running "sudo update-grub" and rebooting.

Hi again, sorry for the delay, i was at work.

The sudo grub update had no effect.

Here is the content of the grub-Menu.lst:
# sample /boot/grub/menu.lst entry for memtest86
#
# This example assumes the contents of /boot is on the root partition.
# If your /boot is on its own partition, remove /boot from the 'kernel' line.

title memtest86+
root (hd0,0)
kernel /boot/memtest86+.bin

title memtest86+ (serial console 115200)
root (hd0,0)
kernel /boot/memtest86+.bin console=ttyS0,115200n8 i8042.nomux=1 i8042.noacpi=1


The location of this file has changed since 9.04 i think.
Now its located in /usr/share/doc/memtest86+/examples

Hi,
I have the same problem, my NEC VERSA E6510's keyboard can work in grub select-menu, but after that, when booting and go into X, the keyboard doesnt work any more, totally no respond.
Im currently use ubuntu 9.10.
Any body can fix this? Please give me any instruction. Thanks.

Hi

Im pretty sure it's a grub problem.

Since alot of changes was made from 1.5 to 2, the old fix does not work anymore.

Im also pretty sure that there is a fix to get the function of i8042.nopnp=1 i8042.dumbkbd=1 that worked in grub 1.5.

Any Grub Guru reading this? Please assist, would be much appreciated.

Hi,

I've tried many distro before (Ubuntu ver 6.06, 7.10, 8.04, 8.10,9.04, open SUSE, KNOPPIX, SLAX ..) but none of them can makes my laptop keyboard and touch pad work. Nothing is recognized even when the system run fine with all features.

Any suggestion?

Thanks

Hi!
i got same laptop and my keyboard works fine in Ubuntu 9.10. You need put those "i8042.nopnp=1 i8042.dumbkbd=1" at /etc/default/grub ,because menu.lst isnt anymore in use at new grub.

[Underlien]

Following the advice from Sonema i added i8042.nopnp=1 i8042.dumbkbd=1 to my grub on this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nopnp=1 i8042.dumbkbd=1"

After a reboot my keyboard works perfectly now!

Thanks alot :D

Same prob, with LG E300 though. My mouse and trackpad work fine, however. Can anyone help?
Thanks.

I'm a newbie experiencing the same problem on 9.10 (never had problems with 8.10). It began suddenly when I was using Audacity.
Now, I can log in, but at that point, the keyboard stops functioning (except the direction keys, one ctrl key and ALT with the F keys).
I don't have a USB keyboard. Anyway to fix this without one?
Thanks,
Marcus
