I’m using a script called /usr/sbin/restart_trackpoint.sh to restart periodically my R61 Thinkpad trackpoint device.
Without this script my trackpoint often hanges and as a side effect causes my whole Gnome desktop to disfunction.
This happens every now and then and it’s deadly irritating …
I’ve noticed that the problem where my thinkpad trackpoint breaks happens most often after my notebook system resume/suspend hibernate functions are in use
I do use the linux hibernate via /usr/sbin/hibernate almost every time I decide to stop my laptop and therefore the hibernate function is something I do use on daily basis.
When suddenly as a consequence of the hibernations the trackpoint problems appeared, I’ve realized that I need a way to place my /usr/sbin/restart_trackpoint.sh script to be executed everytime my system comes from a previous hibernate (e.g. restores).
The documentation of hibernate was not too much clear to me but after some experiments and thanks to something I read on help.ubuntu.com I finally found how to achieve my desired task.
For other people which might have a requirement to set a script to be issued on hibernate suspend or hibernate restore here is how it can be done on Debian Squeeze and in testing/untsable
1. Create new file in /usr/lib/pm-utils/sleep.d/100resume
debian:~# vim /usr/lib/pm-utils/sleep.d/100resume
2.Place in it for instance the script:
case $1 in
## COMMANDS THAT YOU WISH TO RUN BEFORE SUSPEND
echo “Suspeding …”;
## COMMANDS THAT YOU WISH TO RUN AFTER RESUME
## COMMANDS THAT YOU WISH TO RUN BEFORE HIBERNATE
echo “Hibernating …”;
## COMMANDS THAT YOU WISH TO RUN AFTER RESUME FROM SUSPEND TO DISK
Now you might need to modify the above script’s each of the sections to determine what kind of commands you would like to execute before resume) and hibernate)
When you’re done with the file, 3.make it executable
debian:~# chmod +x /usr/lib/pm-utils/sleep.d/100resume
4. Test if your script works with hibernate’s resume and restore
After the hibernate completes, launch the power on pc button and checkout if the system instructions defined in 100resume are being applied.
