I'm a new ubuntu user and loved using it. But I'm now facing a problem using it. i.e., Battery Draining very quickly. ( Mine is Dell inspiron 15 - 4GB RAM - 500 HDD - AMD RADEON HD 7670 graphics. - Dual boot alongside windows8 ) It will come around 3hrs in windows8, but only 1:30 hr in ubuntu. I found that its defaultly using Intel graphics and hence I installed AMD Catalyst drivers and also tlp power management tool and hurray I got around 4hr battery backup. But that joy disappeared very soon, since I installed AMD catalyst drivers my ubuntu booting became very very slow and that's very annoying.
Is there any solution that I can be solved both issues < or > I've to sacrifice one for the other ! :(
Will become your fan if you make my both issues solved ! Thank You!
