Ubuntu, Kubuntu, Xubuntu Based upon a recent email to the X.Org developers' mailing list, Canonical is nearing the point of one of their goals for Ubuntu 10.10 of a rootless X Server, or being able to run the X.Org Server without root privileges.

RE[5]: Big deal...

"Well, its architecture is not the greatest, but pretty much any computer can handle it fine. (By comparison, Windows Vista and 7 and very slow, even though their graphics architecture is fairly well designed.)

Try to play with it when some heavy calculation is running in the background, and see if it remains responsive ^^ Though you're right that "slow" is not the good word. In terms of performance, X is acceptably fast, except for demanding things like games where I think that crappy drivers and compositing are more likely to blame.

Again, don't blame shortcomings of Linux on X11. Just because Linux has a horrible scheduler that can't handle background tasks without locking up the X interface layer, doesn't mean that's how it is for every OS that runs X11.

For example, FreeBSD can run a tonne of compilations and file transfers in the background, without affecting mouse/keyboard input in X.

There's nothing wrong with X11 ... just with some of the OSes that is runs on.
