Description Fest 2010-12-03 02:09:48 UTC
Version:           unspecified (using KDE 4.5.80) 
OS:                Linux

After upgrade to 4.6 Beta, KDE register every hard drive and partition twice.

For example i have one 500GB hdd labeled "Temp". But KDE (in places/removable devices list) show: "500 GB Hard Drive" and "Temp". And so on every hdd and partiton. 

Reproducible: Didn't try

Both hal and udisks running?
Comment 2 Fest 2010-12-04 10:08:29 UTC
If i understand output correctly, yes.

Comment 3 Pino Toscano 2010-12-04 11:53:15 UTC
That's the reason, then.
Comment 4 Fest 2010-12-04 12:04:30 UTC
So Solid checking both of them for info ? Why if from 4.6 Beta KDE depends on udisk ?
Comment 5 Pino Toscano 2010-12-04 20:08:29 UTC
KDE 4.6 can use both HAL and udisks for getting disks information.
If both are running, KDE/solid will expose devices coming from both.

I can confirm this. See bug 258893.

I don't see the rationale for exposing devices coming from both. Is there even a use case, when the two frameworks report different devices? Also, I reckon the information provided by the frameworks should be sufficient to identify and filter duplicates.

I can confirm that removing the HAL resolves the issue. However minimum gimp and k3b are depending on it. If the HAL and udev running at the same time you will get duplicate info about the battery as well.

SVN commit 1206281 by ervin:

Seems the new backends now work good enough. So retire the old HAL
backend on Linux, it's still the default on other unices though. On
Linux it can be reactivated using the SOLID_HAL_LEGACY environment
variable.
