I update my os to Mint 18.1 and I have an alert that said I'm running on software rendering mode when I boot. I'm trying to see which driver I'm using and I have this result.sudo lshw -c video  *-display NON-RCLAM       description: VGA compatible controller       produit: Cape Verde XT [Radeon HD 7770/8760 / R7 250X]       fabriquant: Advanced Micro Devices, Inc.

I tried to install the open source driver for Radeon like this sudo apt-get install xserver-xorg-video-radeon but nothing changed.Is there something to do?Edit 1Here is lsmod output :Module
