Yesterday I released the next KPowersave version on sourceforge.net and added a announcement on kde-apps.org (and today on freshmeat and forge.novell). This release (v0.5.11-rc5) is planed as the last release candidate before the next stable release since September 2005.
I fixed the handling of set brightness. In the previous version KPowersave allowed to use all available brightness level to be set. But e.g. on machines with PMU brightness interface the lowest level off the display. From now only the last usable brightness level, defined by powersave, can be set. With powersave >= 0.12.7 you can now also change the brighness on machines supported by pmu and omnibook module.
On a request I added a function to check if the machine is a laptop, by asking HAL. Now KPowersave display laptop specific widgets and functionality only on laptops. I think this is now less confusing for the user of workstations which not expect to be able to configure lidclose handling.
The new version also include: handbook, translation and documentation updates and fixes; a Slackware specific fix again; some code cleanups and a little fix to prepare for QT4. I added furthermore a patch from Holger Macht to allow the root user always all kind of suspend/standby independent from the powersave settings for the other users.
Fell free to download the current version (available for SUSE, Fedora Core 4, Mandriva and I think in the next days also for Debian and U/Kubuntu). All bugreports are welcome for the stable release.
