Testing Precise Pangolin Beta2

[Gustavo R Leal]

I believe I've found the problem of excessive swapping with 1GB of memory.

There is a script "/usr/lib/pm-utils/power.d/laptop-mode" that is setting these weird values to VM tunable kernel parameters when on AC power:

dirty_background_ratio=5

dirty_ratio=10


The line 69 of the script is the following:

        write_values 0 10 5 500

Changing the line with these values resulted in being able to run the system with 1GB without swap and good performance.

        write_values 0 90 20 500


I think it needs some attention.

Thanks,
  Gustavo Rybarczyk.
