I installed Ubuntu 15.04 on my laptop Dell Inspiron 15R SE 7520, even installing the proprietary drivers from the AMD website and I am with the following problems:
- Low battery life time (less than 1: 30h);
- Low graphs score in Steam;
- Often the system does not start, it is in black screen.
Dell Inspiron 15R 7520 SE; Processor Intel Core I7 3612QM; Memory Ram 16GB; Grafics: AMD Radeon 7730M & Intel HD4000(Hybrid) Hard Disk 512SSD
Could anyone help me?
