LinuxQuestions.org - [SOLVED] GNOME starts in 3.5 minutes and I have timestamped the X log. Remove the bottlenecks!

My radeon driver loads GNOME in 3.5 minutes while vesa takes 5 seconds.

I've installed the Radeon firmware, and I have the Radeon modules installed. There are no errors in the Xorg.0.log which can be found here.

I've written a script that extracts and appends the last line of Xorg.0.log to a separate file every one second and inserts the current time. This is that log file:

You can see how much time is being wasted at particular lines in the log (or rather the lines immediately following these lines in the log, since tail will keep extracting the same line while the bottleneck is being executed)

Note: This is the continuation of an earlier thread which has addressed all the minor problems I had before I narrowed it down here.
