xgl - System monitor bug in hardy...

On Ubuntu's latest release, Hardy Heron, if you are using xserver-xgl package for graphics, you are in for a surprise.

The system monitor carries on a bug in xgl package wrt incorrect reporting of memory usage, and shows processes using zillion bytes of memory.

I started using xserver-xgl from the times in Gutsy when Compiz would not run on my hardware without that. However, I didnt quite notice this until I involved myself with beta release of hardy.

As it happened, I raised this issue on the Ubuntu forums (more than once actually, link-1, link-2), and finally after a few discussions/posts, it was discovered that

  • xserver-xgl has a few bugs
  • no more active development is happening on this stream of packages
  • Compiz should work without needing this package as well.
As a result, I tried removing xgl from my laptop, and voila, memory consumption numbers are from earth again.. the martian numbers have left... :)

Attaching two screenshots here to give the idea of the Martian numbers...
