Hi,
generally speaking, everything seems to be working nicely. I only have 2 issues:
1- I use module nvidia_bl to allow LCD brightness to be set on my Vaio. Until now, with HAL, it was working nicely. A second backlight class is created in /sys/class/backlight/nvidia_backlight and KDE PowerDevil was using it. Now that HAL is gone, the class is still there, together with the non-working /sys/class/backlight/sony but brightness is stuck to 100%. What can I do?
2- Windows partition is mounted under /media/<name> with mode 0600. I don't remember if KDe 4.5.4 mounted it with same permissions, but now I have some access denied error when some programs try to read files in there. How can I change it to be mounted 0644, for instance?

ok, this is not due to permissions, but instead it's because udisk is mounting ntfs partitions with bare old ntfs and not with ntfs-3g.
why? hmm
Sounds like it should work. I'm gonna try it, thanks!
Speaking of the other issue, with some udev monitoring I can confirm that the system keeps talking to /sys/devices/virtual/backlight/sony while it should actually talk to /sys/devices/virtual/backlight/nvidia_backlight.
If I remove sony-laptop module, it works. But that module does other things besides backlight and it's not a good idea to blacklist it.
It also seems like it's no longer possible to tell udev to "ignore_device" a device.
There should be some method to tell udev/upower which device to use when multiple devices of same type are present. Also this is not a KDE issue, but it's more likely to be udev/upower related.
How are you starting KDE? I had problems with PowerDevil and brightness when firing KDE from console. Also suspend and hibernate was missing. With KDM everything worked... What does "echo $XDG_SESSION_COOKIE" say? "ck-list-sessions" should say something about your session.

There is a specific brightness issue related to my laptop model. It's a Sony Vaio but the standard sony-laptop module in the kernel does not correctly handle its backlight device. There is a hack in form of a module not included with kernel, named nvidia_bl, which can correctly handle backlight functions, and when loaded it creates a second backlight interface in sysfs, and PowerDevil should be talking to this interface.
All this is mostly unrelated to the specific issue though, since everything was working fine until KDE 4.5.4 with HAL, probably because hal defaults to whatever backlight interface comes last in the modprobe sequence (my assumption).
I'm starting KDE in init 4 with KDM.

I tried it but it doesn't work.
I read in that thread that it works for plugged in USB sticks, but not for internal devices. What I'm mounting is a NTFS partition on my laptop's internal disk, not an USB pen, so I guess this is why it's not working.
I wonder if blacklisting kernel's native ntfs module would make it default to ntfs-3g or would only make it fault. Gonna check.
you surely don't plug/unplug internal devices, I think...
Yes of course I know this, but since leaving it undefined in fstab and mounting it on the fly from dolphin used to work with hal-based kde, then why shouldn't it work now?
