I've been casually using Ubuntu for a few years but this is the first time I've had real trouble installing the OS. I bought a Lenovo laptop and I've run into a few problems after installing:
After formatting the drive and installing Ubuntu 11.10 (64 bit) the disk utility gives me the message "the partition is misaligned by 3072 bytes" and suggests repartitioning. I formatted and reinstalled and am getting the same message. How exactly do I align a partition properly?
The laptop in question has 4 gigs of RAM but Ubuntu seems to only detect 3.5. Why is this and what can I do to make sure the system uses all four gigs?
When shutting down the laptop hangs at the Ubuntu screen. The only way to turn it off is to hold down the power button.
Also, I've read that 64 bit Ubuntu has issues with flash. Is this still the case? Am I better off installing the 32 bit version of 11.10? Any help with these issues would be much appreciated as I'm in over my head here.
