Installing AMD/ATI drivers in Debian
After having a fresh Install of Linux on a new system, the next hardest thing to do is to configuring Graphics card. Especially if we have a dedicated Graphics card or may be two Graphics card in Cross-firing mode or SLI mode. I still remember the day when I installed Debian on my laptop for the first time, I didn’t knew how to configure the Graphics card. By default, the Graphics card was up and running in high performance mode. I have an HP gaming laptop with Cross-firing Graphics at that time. Soon after the Install. I saw my system heating up like it was put on a gas stove. Soon I saw my system lagging very much and after some time, it automatically shutdown. I was really wondering what could have happened ? When I again turned on the laptop, I saw a message saying “ Your system has been undergone Thermal Shutdown.” I was shocked logged back in to my Windows until the lap has been fully recovered. Later only I learned, How to configure Graphics cards, especially AMD/ATI. SO lets us see how to configure the Graphics card :
