Bearcat, 13.04 is supposed to be able to deal with MS's UEFI. Suggest to Google a bit on this "hot" topic how advanced the developers are to deal with this stumble-block.

edit: Here's one hit in English, all the others in the top 20 are in Italian, so not giving those ;>) http://linux.lyricastic.com/topic/ubuntu-13-04-32bit-uefi/

For those who try a lot of different versions or flavors of Linux and use Firefox and Thunderbird, the following may be useful to know. Each time doing a persistent [casper-rw] enabled install, all is lost in settings, tweaks and whatnot unless you backup and restore, which slows you down of course. In the case of Firefox and Thunderbird, it's handy to copy the profiles with all their content to a permanent location on a HD. You find those in the .thunderbird and .mozilla subfolders of Home. These folders are default hidden, so you need to tell the file explorer such as Nautilus to show hidden files and folders. After copying after exiting out of the respective application, open a console and start thunderbird/firefox with

sudo thunderbird -profilemanager
sudo firefox -profilemanager

This opens up screen up where you can manage profiles. Select create, chose a name, and copy the full path from your file browser into the path field [In Nautilus, go to the permanent profile store location and hit Ctrl-L to get the address in text form.] Paste this path in the path box and apply. Then take the start thunderbird/firefox button to confirm you're using the new location. It's easy to see in the file browser as the modified time stamps assume current time on several file [sort for easy of viewing]. When satisfied, exit the program, start is again and delete the old profile from the selection box and voila. In my case, gained over 350MB in space on the USB memory stick drive, and gained substantial speed at that, PLUS reduced wear as web browsing writes many files ongoing.

Use it or loose it :D

P.S. Doing this also allows you to share your Thunderbird mail in a dual boot environment between Windows and Linux [somehow when typing this, flashback, as if I typed this before some longer time ago, and it still works :D]. About Firefox I'm not so sure... not all extensions work across multiple platforms, so I'm keeping the profiles for the web browser separate, and continue to use X-Marks to sync tabs/history/bookmarks across.

Will have to give it a shot and see what happens. Thanks sek.

Help, Linux ate my RAM: http://www.linuxatemyram.com/

Just kidding, a quick Google on the Wazzup with the 8 core system using 1.8GB in memory and another 3.8GB for caching... truly leaving 8-1.8-3.8=2.4GB not doing anything. Fine my me :D

Crunch On.

P.S. Swappiness=10 and Swapfile use 0.0 the fastest there can be.

A must have 'Preload' to speed up your Ubuntu and Unity doing what the name suggests. The description in Synaptic:
System is flying, on air. 1.7 for BOINC, 3.6 used prior to Preload in Cache, let's see how this works out. Unity is already offering the seek and thou shalt find apps used previously much quicker.
