I have a Dell Inspiron 15R SE (click here for details). I have installed Ubuntu 12.10 via Wubi on it. The OS works perfectly fine, but there are some issues:
- The fan speed is so high that it is actually audible. This doesn't happens when working with Windows 7.
- The laptop gets somewhat hot. Again, not an issue with Windows 7.
- Instead of showing me the name of my ATI graphics card, it shows "standard" or "generic" display drivers. (Pardon me, I cannot recall the exact name.)
- The battery drains twice as fast as it does on Windows 7.
Other than the problems I have mentioned above, it works really good. No issue on software side at all.
