I performed a clean install of 13.04 final beta on my S76 Gazelle (circa 2006; C2D, 2GB Ram, Nvidia Go 7300). The system is hogging my resources and performance is awful. At idle it's using about 50% CPU load on both cores. I installed the recommended Nvidia driver (304, I think?) and this didn't help any. Ram usage is about what I expected at around 350-380MB.
This is a fresh install on a formated HDD with ext4. Performance is not sluggish at all with other linux OSes, such as Mint 14 or CentOS. Any suggestions?
