(I'm sorry if this is assigned to the wrong component, this is the closest as far as I know) I'm using KDE 3.5 with FC5 on a laptop, and I've noticed that the battery monitor in the notification area disappears after first use. When I started FC5 for the first time or logged into a new account, it appeared, but disappeared after the next reboot. Enabling or disabling the 'Restore last session' option doesn't change anything, and pressing the 'Start battery monitor' button in the 'Laptop Battery' section of the KDE control center doesn't help either. What does work, however, is disabling the battery monitor (with a checkbox in the same section of the control center, I'm not in FC5 right now and don't remember the name), pressing 'Apply', re-enabling it, and pressing 'Apply' again. The battery monitor appears, but it's gone again after the next reboot. I'm using kdelibs-3.5.1-2.3 and kdebase-3.5.1-5. GNOME's battery monitor works fine, so I think it's a problem with the specific program instead of the kernel or HAL. Any information I left out?
there's new KDE-3.5.3 in FC5-update since 1 week. The new version includes several fixes and the fix for this problem, too. You should update to new KDE version please. Thanks
