CoLinux is only the Windows code to run the Linux kernel as a process. If the version of Linux you have decided to run with CoLinux has X installed and configured, then yes it will run.
Think I downloaded Gentoo Deluxe onto my laptop (where I installed CoLinux).
I don't know if that has it or not. I worked from home today so I didn't need to fire up my laptop to check it out.
On a side note, I've been trying to decide which distro to run on a regular basis. I've downloaded several and installed into XP (Virtual PC) to try out.
All are working well but I've been trying to get SuSE 9.2 and all the mirrors I've checked out either SUCK or the download is corrupt.
If anyone knows of a speedy site from which I can download SuSE 9.2, I'd appreciate it.
