--- Comment #11 from Martin Steigerwald Martin@Lichtvoll.de 2011-05-09 15:59:09 --- Ok, now it did it! First with 256 MiB reserved_size then also with 128 MiB reserved_size. Two KDE 4 sessions with compositing enabled. It had some problems to freeze tasks initially, cause an rdiff-backup and two KDE 4 desktop search indexers were running, but after some tries it did it. And if the rdiff-backup and those desktop searches fill the laptop harddisk with I/O requests up to its limit, thats just what to be expected. I am now testing 128 MiB and looks whether it works reliably. Still I wonder why 2 MiB was enough for one KDE 4 session, but two need something around 128 MiB.
