The current SUSE version of pm-utils is pretty old. Rpm -q said somethink like 0.99.4.20071229. And it also contains a hacked support for s2ram, which is nowadays in upstream version. There has been also a bnc#378883 – Need an updated pm-utils I started a work on this week.
A new pm-utils package for openSUSE is available in home:mvyskocil:branches:Base:System. The HIBERNATE_METHOD is no longer supported, because upstream version contains something better – modules. There are three methods how to run software suspend on Linux
- kernel – plain echo something > /proc/something
- suspend – tool contains a lot of quirks needed on some HW
- tuxonice – kernel and userspace support for hibernate, not in upstream kernel, nor in openSUSE
Because there are too many ways in current Linux world, pm-utils simply support all by specific modules stored in /usr/lib/pm-utils/modules.d, which implements appropriate functions for suspend/hibernate and hybrid. The SUSE default is uswsusp module calls s2ram/s2disk/s2both from software suspend project, because it should be considered as a safe default.
If you want to use different module, you can add a config file somewhere to
and set the value of SLEEP_MODULE.
# The default sleep/wake system to use. Valid values are:
# kernel The built-in kernel suspend/resume support.
# Use this if nothing else is supported on your system.
# uswsusp If your system has support for the userspace
# suspend programs (s2ram/s2disk/s2both), then use this.
# tuxonice If your system has support for tuxonice, use this.
# The system defaults to "kernel" if this is commented out.
You can type more methods, which will be called, so SLEEP_MODULE=”kernel uswsusp” will use kernel and if it fail, or not available, it call uswsusp. Please note that config files are read in C sort order, so names matters.
So please install new pm-utils and test it and tell me if you found any regression (please inform me about a regressions only, I cannot fix generic suspend problems).
