I have 4 GB of memory on a 32-bit laptop (Lenovo T61, in case it matters) running Ubuntu 9.10. Is there any way to make use of it all? Ubuntu only sees 3 GB, of course. Is there any way I can utilize the last GB of memory? Thanks!

You should NOT use the server kernel unless you are running a server. To use all of your laptop's 4 GB install the PAE version of the generic kernel with:

sudo apt-get install linux-image-generic-pae

Is there any downside to using linux-image-generic-pae over the "normal" kernel? Thanks! – Joe Casadonte Jan 12 '10 at 1:51

PAE makes memory access slightly slower. VERY slightly. Other than that, no. – Kim Jan 13 '10 at 6:25
is that a 32-bit kernel? if so, thats cool. – djangofan Jun 25 '10 at 18:15
