Newest kde-misc/kosd is 0.7.1. The one in portage: 0.6.2 has some malfunction on KDE 4.7.0. Please bump it. http://kde-apps.org/content/show.php/KOSD?content=81457 Changelog: Changelog from 0.7.0 to 0.7.1 * Fixed a possible crash, if no mixer control named "Master" exists Changelog from 0.6.2 to 0.7.0 * Changed KOSD Keys Service to use ALSA directly instead of relying on KMix Changelog from 0.6.1 to 0.6.2 * Fixed CMakeLists.txt not to link against libsolidcontrol which is no longer used Changelog from 0.6.0 to 0.6.1 * Made KOSD Keys Service compatible with KDE SC 4.6
Created attachment 283979 [details] Ebuild that worked for me. Just install it from local overlay.
Bumped. Thanks for reporting!
