Title:
/etc/sysctl.conf not loaded on resume
Status in Ubuntu Netbook Remix:
Invalid
Status in “pm-utils” package in Ubuntu:
Invalid
Bug description:
Binary package hint:
pm-utils
What release of Ubuntu I am using:
Hardy 8.04.1/Netbook remix 1.0.1 (kernel version2.6.24-19-lpia)
What version of the package am I using:
pm-utils 0.99.2-3ubuntu10
What I expect to happen:
If I set variables in /etc/sysctl.conf (or /etc/sysctl.d/*) they should still
be set both after boot-up and after resuming from suspend
What happened instead:
Variables are set after boot but after suspending they are no longer loaded
(can be confirmed by using "sysctl -a") and have to be manually reloaded by
using "sysctl -p"
A bit more detail:
I have an acer aspire one, and I want to set up the wifi led to flash when
I'm using wifi. This can be done by setting the appropriate variables in
sysctl.conf. However, this only works after the initial boot, and if I suspend
then the led no longer works (it's probable that this also works after
hibernation too but hibernate's disabled on my machine).
After a bit of investigation, I discovered that it was because
variables set in sysctl.conf weren't being loaded after resuming, and
if I ran "sysctl -p" (which reloads sysctl.conf) the wifi led came
back to life. (I suspect this might also disable any network
connection tweaks that are defined there as well, although I haven't
tested this myself)
Temporary solution:
What I've done for now, is dropped a script in /etc/pm/sleep.d that calls
sysctl -p after resuming. I've attached the code (if you want to use this, make
sure that the script is executable...)
Theory about what's going wrong: Not sure. I'm not even sure that it's
a problem with pm-utils, however, there is definitely a difference in
the way that the system is being reinitialised on resume compared to
when it boots.
