Description Tom Chiverton 2010-04-01 22:40:44 UTC
Version:           1.0 (using 4.4.2 (KDE 4.4.2), Kubuntu packages)
Compiler:          cc
OS:                Linux (i686) release 2.6.32-18-generic

Even though in 'power management' I have 'when power button pressed' set to 'suspend to disk' set in all profiles (and can confirm which is selected via the system tray icon), nothing happens when I press the power button.

This worked in KDE 4.x under 9.10, appears broken by using the 10.4 beta.

Hardware is a Dell Inspiron 1525 laptop.

Worse under Ubuntu 10.4 beta 2's packages, now the screen changes to a Kubuntu logo with animated dots underneath and hangs there.

CTRL-ALT-F1 swaps to text console but the keyboard doesn't respond when I try to login.

I *suspect* it's trying to reboot, and the hang is due to my CIFS mounts not being pulled down before the wireless is, but that's a different bug; it should be hibernating, not rebooting.

Using the 'suspend to disk' option on the logout dialogue all is well.

This was rock solid under 9.10 with Kubuntu backports of the same KDE4 version...

Using buttons added to the main menu panel work fine too.

As per https://bugs.launchpad.net/ubuntu/+source/kdebase-workspace/+bug/553557/comments/9 and following exploration, this appears to be something in Kubuntu or Ubuntu's packaging that causes the ACPI scripts to thing KDE isn't running, and do their default thing (power down).
