Some current laptops include two graphic cards with different abilities and power consumptions – often known as a hybrid graphic.
If you own one like that with a combination of intel and amd this you need to manage how the OS and system will handle them.
The idea is that a low-power INTEL-GPU is used for normal use and for more powerful application use like gaming you can switch to the more powerful AMD-GPU.
The recommended way is to use open-source drivers.
So install ati and intel open-source-drivers:
sudo pacman -S xf86-video-ati xf86-video-intel
If you have a newer AMD GPU you may need
xf86-video-amdgpu installed instead of the ati driver.
By default, without any
xorg.conf file the system starts with intel driver. To use radeon card you have two possibilities:
1. Using xorg-conf file
If you want manual configuration, create /etc/X11/xorg.conf.d/20-radeon.conf, and add the following:
Section "Device" Identifier "Radeon" Driver "radeon" EndSection
2. PRIME Render Offload
can be used to start a game (or other) on the AMD GPUConnect with us:
