[Bug 1385089] Re: keyboard sometimes doesn't respond at login

[diehard67]

the only changes were to work around this, adding sleep 2 before exec
lightdm in /etc/init/lightdm.conf

I know lightdm.conf  calls plymouth quit before running lightdm itself
but I suspect it is not done quitting when lightdm starts running.

like I said if I tell the kernel to give a text login and start lightdm
later in the boot process in rc.local the keyboard works almost every
time.

truth be told I have no idea what to look at or how to get more info, if
there some way to get plymouth, lightdm, x and the kernel to give me
detailed logs during boot?????

I should also mention my sisters netbook is not a particularly fast system
asus eeepc x101ch

1 gb of ram
intel atom n2600 at 1.6 ghz
dual core with hyperthreading

snipit of /etc/default/grub
GRUB_DEFAULT=4
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash text"
GRUB_CMDLINE_LINUX="i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.semaphores=1"

rc.local
#!/bin/sh 
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.

hdparm -W0 /dev/sd?

/etc/acpi/lid.sh

killall plymouthd

service lightdm restart

exit 0

the upgrade to 14.10 put lightdm.conf back the way it was

Title:
  keyboard sometimes doesn't respond at login

Status in “plymouth” package in Ubuntu:
  Incomplete

Bug description:
  I have tried diferant display managers (kdm nd lightdm) both are
  effected sometims whn my sister turns on her netbook she can't type in
  her password untill she puts th cmpute to sleep and wakes it up again,
  this seems to be randome, from what I have been able to fine from
  googling all over the place plymouth is to blame for this, seems to be
  if it is still running when whateverdm starts you will not bable to
  type.

  on my own laptop I have had the same problem and was able to fix it by
  adding a sleep 2 before exec lightdm in /etc/init/lightdm.conf

  my sisters netbook needed  more then that, he delay got to 6 seconds
  long and still wasn't reliable, I had to modify /etc/default/grub to
  ass text after splash then put service lightdm restart in rc.local so
  she could login most of the time.

  she has had the problem in 14.04 and now in 14.10, I have had it sense
  13.04
