I've been running Ubuntu 11.04 for around 18 months, and avoided upgrading due to my crappy graphics card (intel 855GM) which is famously not-quite-3d, so Unity wasn't going to work well.
However, which various "horsepower" configuration options now available, I though I'd go modern.
My machine is a 1.5Ghz Intel Celeron, 750Mb of ram, and runs Gimp, Firefox, Libreoffice acceptably. I've even captured and edited 45 minute long tracks in Audacity.
But "someone" has decided that my machine isn't even good enough to run LUbuntu - no PAE. But
I've only got 750Mb - PAE is irrelevant.
I've upgraded to 12.04 which runs fine, but it's going to be a backwater.
What can I do?
