Bug 271625 – kde battery indicator doesn't work with 2.6.28 kernels

• Product: Gentoo Linux
• Status: RESOLVED WONTFIX

[Description ta2002 2009-05-29 07:53:02 UTC]

On two different laptops, after upgrading to a 2.6.28 kernel, the battery indicator no longer appears in the panel.

The control center says:

"Your computer seems to have a partial ACPI installation. ACPI was probably enabled, but some of the sub-options were not - you need to enable at least 'AC Adaptor' and 'Control Method Battery' and then rebuild your kernel."

The relevant part of the 2.6.28-r5 kernel config:

# Power management and ACPI options

CONFIG_PM=y
# CONFIG_PM_DEBUG is not set
CONFIG_PM_SLEEP_SMP=y
CONFIG_PM_SLEEP=y

"kde battery indicator" ?

KDE3? KDE4? From which package is this application from and which version?

KDE3 (3.5.9 to be exact). The klaptop daemon provides this information.

This actually looks like some kernel (possibly configuration) problem (existing all the way up to my current kernel - gentoo-sources-2.6.30-r6).

CONFIG_ACPI_BATTERY:
This driver adds support for battery information through /proc/acpi/battery.

From /var/log/messages:

Thanks. 

KDE3 is about to be removed from Portage, so closing this then.
