About two years ago I first tried Ubuntu (11.04) on my sony vaio fw11e and I remember that I was impressed by how smoothly everything just worked out of the box. For different reasons i reverted back to windows 7 however.
Today I tried installning ubuntu 12.04 32-bit on the same computer and now everything seems a bit "off" (slow resonse time on mouse clicks etc). First of all the CPU-fan is at maximum load, blowing out burning hot air all the time. Secondly the suggested proprietary graphics drivers from ATI wont install correctly, and I get a strong feeling that the hardware overall is not recognized correctly in the OS.
Is there any reason that the older Ubuntu 11.04 would be working better with my laptop (especially the ATI drivers) or could there be another reason for the un-smoothness that I am experiencing.
Should I try installning older versions of Ubuntu?
Is there a way to see if the motherboard chipset drivers are correct?
