Now although I have tested the latest kernel 3.4 ppa release and I must say it
does run quite well and fixes some of the major bugs in Ubuntu 12.04 including
of course the bug mentioned here regarding standby/suspend, it is still not a
release version and I am still using kernel 3.2.0-24-generic release version.
Now since this version many of you probably noticed that the script I have
posted before providing a quick fix for this bug no longer works. At least for
me it no longer works. If for you it still works then don't touch it. It seems
for me however some issues may have been attempted to fix regarding sleep and
wake up driver issues. As a result the previous script no longer works, however
I have written a simplified version which takes in consideration these fixes
and this seems to work like a charm for me.
As previously...
Step 1: Open up a terminal and create a scrip file as follows:
sudo gedit /etc/pm/sleep.d/20_custom-ehci_hcd
Step 2: If and only if you have problems with your current script and
your machine refuses to sleep or wake up on kernel 3.2.0-24-generic then
replace the entire code with the following:
#!/bin/sh
# File: "/etc/pm/sleep.d/20_custom-ehci_hcd".
TMPLIST=/tmp/ehci-dev-list
case "${1}" in
hibernate|suspend)
;;
resume|thaw)
chvt 1
chvt 7
;;
esac
Step 3:
Give the script permission to run by typing the following in the terminal:
sudo chmod 755 /etc/pm/sleep.d/20_custom-ehci_hcd
Hope that helps and it works for me nicely. :-)
