When running Parallels 3 I had all my tools working for Ubuntu 8.04 and Windows XP. Because I heard there would be extended graphics capabilities with 4.0 I upgraded. Big mistake. I'm operating slower with the graphics intensive programs but I can live with that. The one thing I can't live with is that Parallels Tools will not install on my Ubuntu VM. I tried mounting the drive and running sh install as root and nothing. This is horrible. Please help.
