It is a annoying bug (description stolen from KDE bugzilla): The.xsession-errors file has grown periodically with "QFile empty file name warnings" and kept harddisk running. This happened only if an button action for the LID button was checked in klaptop. On my notebook only the LID button seems to give status (for power and sleep buttons, the /proc/acpi/button/*/*/status files are missing - seems to be pretty standard since the buttons generate normal ACPI events). Missing acpi status file results in empty QString acpi_power_name in file portable.c. The warnings come then from the QFile open() call in laptop_protable::get_button(). Here are the solutions: http://bugs.kde.org/show_bug.cgi?id=103437 http://bugs.kde.org/attachment.cgi?id=13001&action=view Maybe these fixes could be included in portage ? Reproducible: Always Steps to Reproduce: 1. 2. 3.
Applied in kdeutils-3.4.3-r1/klaptopdaemon-3.4.3-r1. Thanks.
