[Digikam-users] Problems on Ubuntu 11.04

[Thomas Güttler]

Hi,

I use the ppa for ubuntu 11.04 from philipp.
/etc/apt/sources.list.d/philip5-extra-natty.list:deb 
http://ppa.launchpad.net/philip5/extra/ubuntu natty main
/etc/apt/sources.list.d/philip5-extra-natty.list:deb-src 
http://ppa.launchpad.net/philip5/extra/ubuntu natty main

root at e520:~# digikam --version
Qt: 4.7.2
KDE Development Platform: 4.6.2 (4.6.2)
digiKam: 2.1.1

I removed all old digikam configs, since I only tried it, but never
used it.

I have 35.000 jpegs. In the lower left corner I see "Scanning 0%" which 
takes quite long. I can't use the GUI. That's not very user friendly, 
but no problem for me.

Then the scanning seems to be done. But
digikam uses 30% CPU 50% on a modern Laptop CPU (Intel(R) Core(TM)
i5-2410M CPU @ 2.30GHz). But I don't do anything with the GUI. But
what does digikam do? I guess the import of my directory was done:

root at e520:~# strace -p 3343 2>&1 | grep open
open("/home/guettli/Bilder", 
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 50
open("/home/guettli/Bilder", 
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 50
open("/home/guettli/Bilder", 
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 48
....


Then I want to look at some pictures: only some pictures are
visible. And the one which can be seen are blinking. But most pictures
are not visible (white backgrund).

I want to know what digikam does:


strace -p 3343

FD 10 and 20 are unix sockets. I could not find the unix-domain socket 
file or the other attached process with netstat.

How can I use digikam2 on Ubuntu 11.04? Or should I wait for 11.10?
