After some months working in a VirtualBox VM with Linux Mint (the host as a Windows 7), I've finally installed Mint 17.1 Cinnamon on the same computer.
And the experience hasn't been good. The fact is that running Mint directly, bare to the metal, is slower than running Mint thru VirtualBox, on a Windows 7 host...
I imagine, I'm not sure, that the problem is in my video card (an ATI Radeon 5450). The computer is fast enough (AMD Athlon X3 450, 6Gb RAM, a simple SATA HD), but it seems that neither the open source x.org drivers nor the fglrx drivers are performant enough.
And my question is, what can I do to make Mint 17.1 usable in my computer?
