I have installed Ubuntu 12.1- on my Dell Inspiron 15r 3rd gen Laptop.
It has ATI Radeon 7670m graphics card.
How do I install drivers for all my hardware safely?
Currently gesture of trackpad, fan speed, etc are not working properly.
How do I test whether all my hardware is properly working?
Is there any standard tool for error checking, benchmarking, etc for checking hardware?
Thank You.
