I've purchased Parallels to run Linux on an Intel-based iMac. Installing Ubuntu 6.06 went flawlessly and the Parallels UI both looks nice and is instantly accessible, so congratulations to the Parallels team for that! However, when running Ubuntu, responsiveness is lacklustre. Every 1-2 seconds, the VM seems to pause for a fraction of a second, which is very noticeable. It makes the mouse cursor jumpy, and even the Linux terminal cursor blinks at an uneven rate -- very annoying. I noticed there's "Parallels Tools" which offers smooth mouse movement and presumably fixes these issues, but it's only for Windows. Are there any plans to offer this fix for Linux? With the stuttering, Parallels just can't be used doing any real work in Linux... I'm rather disappointed.
