Windows size incorrect, slow graphics performance and no seamless mode

[Dane]

I used to use kubuntu 9.10 x86 in vbox with no problems. i've recently created a kubuntu 10.04 x86 in vbox. it has the incorrect window size before and after i installed guest additions. the graphics performance is also slow as if guest additions isn't installed. i've reinstalled guest additions over and over. at the moment my work around is to set the display size in kubuntu to my native size and then run it in full screen mode. i also cannot use seamless mode. And the window doesn't auto adjust. all other guest addition enhancements work however. my host is windows 7 x64.

Thanks

Does "ps ax | grep VBoxClient" in the guest show any output? If not, can you start VBoxClient-all (as user) manually, and does that fix things? If that doesn't help, does

$ VBoxClient --clipboard -d
$ VBoxClient --display -d
$ VBoxClient --seamless -d

produce any output?

Regarding the speed, does increasing the main RAM size help? KDE 4 is rather memory hungry.
