So recently ive decided that Windows 8 is annoying due to the fact its optimised for touch and though it was 50/50 between Ubuntu 13.04 and Mint, ive opted for Ubuntu. Anyway, I have a good, modern 'sleekbook' (AMD version of an ultrabook (Samsung Series 5)) which I love due to the fact that in Windows it was running in about 5 seconds, could play Civ5 (I know, i know! ) and runs like a dream.
When I initially installed Ubuntu I was happy that it was fast (Not faster then Win but on par) but over the last couple weeks as ive used it more, ive noticed its got a LOT slower. When I first login I click on Firefox and the icon glows on and off for about 5-10 seconds before it opens, when I try to open up settings (software and updates) it takes about 10-20 seconds and I keep thinking ive not clicked properly so I click again and when Ubuntu catches up with itself it opens about 5 windows.
Ive looked on the forums and have found quite a few people reporting the same thing, one person suggested typing sudo hdparm -Tt /dev/sda to check speed results and this is my results
Timing cached reads:
3944 MB in 2.00 seconds = 1972.88 MB/sec
Timing buffered disk reads: 286 MB in 3.02 seconds = 94.76 MB/sec
Its my understanding that this is acceptable for an older computer but on a new sleekbook is poor.

Secondly, another small niggle is that when I start my laptop the screen brightness always resets itself. I always have my laptop on the lower brightness settings as the brightness does my eyes in but everytime I restart it resets to the highest brightness regardless of battery or AC. I was wondering if it was possible that once I set the brightness I could save it and have that brightness everytime I boot? Third small problem is that ive managed to get the power management icon in the taskbar working wonderfully which displays all powermanagement plans and speeds in order to conserve battery, however, again this resets at boot and I was wondering if their is a way to save this as default?
I want to stick with Ubuntu but the speed thing is a massive issue that if doesnt get corrected I will end up abandoning. This is the millionth time ive tried to integrate to Linux over the last 10+ years but its been a hard and rocky road thats ended up with me ditching it in favour for Win so this time I hope to change that!
Thank you in advance, folks and I hope that together we can resolve this issue speedily!
PS. It might be worth mentioning that I use TLP and the config file is pretty much default other then radio settings. I also need things explained in 'lamer' terms as im still learning my way around.
