Stock Ubuntu 9.04 (geological time frame to install) and as you can see with Firefox loaded and logged into this blog we are into swap already. I increased the swap size a bit from the last install just in case that is causing any issues with hibernate. I doubt it though. Haven’t even got to the flash plug in yet!

Hibernate works when you adjust the settings in ‘power management’ so that closing the lid selects hibernate instead of ‘blank screen’. I wonder if there is a similar setting in Debian 5?

Installing LXDE and fresh booting into an LXDE session reduces the memory footprint with Firefox running to around 91 Mb

             total       used       free     shared    buffers     cached

-/+ buffers/cache:         91        153
Swap:          768          3        765

But we are still into swap with just Firefox loaded (no flashplayer). And so to the stock dwm in the Ubuntu repository – which isn’t quite behaving as it should (shift-alt-enter does not start a new terminal for instance, I had to alt-p and type xterm). 77Mb with one Firefox window, but at least there is no swapping yet.
