yes, you're right, i enabled the compositor in my xorg config, to play
around with it when i upgraded to the latest xorg. at that time there
was no point turning it off (from my point of view) as i still had to
explicitly use transset etc to make use of it. now that it's starting to
be used inside apps i may as well turn it off in my xorg.conf.
am i right in understanding that my being able to use it (without it
being sluggish) will be down to new versions of the ati kernel drivers
(i have a radeon card and use the kernel drivers for it rather than the
ati ones)? or is it likely to always be slow on my hardware (radeon 9000
mobile w/ 32mb). it's no biggie, but the drop shadows look so nice ... :)
