Re: Fujitsu Stylistic ST 4120 Ubuntu?
Good Luck with this ...
I had the Fujitsu T4020 - predecessor to your version. Last Ubuntu version that worked well with was 8.10. Then, in 9.04, they changed the Linux kernel so it no longer saw the buttons on the bezel -- basically ending my Linux use on it because I needed those features badly at the time.
So, the "side buttons" (if these are the ones on the bezel) most likely are not going to work.
Also, the processor is not very powerful. For simple stuff like email and web browsing, it was OK. But for more demanding stuff like videos, it lagged badly. I even boosted it to the maximum of 2GB of memory, and while that worked better, it was still a poor performer.
The newer Ubuntu versions are designed for more power machines with more recent video chipsets -- so even if it does work, it's likely to have low resolution (1028x764 at best).
Ubuntu 12.10; Mint 15; MS Win7 & Win8.
