I try to install Parallels Tools on OpenSuse 12.3 (3.7.10-1.16-desktop). Although there is no error message, the guest additions are not working. The screen resolution doesnt resize, there is no copy / paste etc. I am running OSX Lion with Parallels Desktop 7 (all updates installed) I already tried reinstalling and this: http://forum.parallels.com/pda/index.php/t-262751.html without any luck. Does anybody have an idea what i can do? In the meantime i am using virtualbox. It's awfully slow, but working out of the box.
