I have a hp spectre with an intel® Core™ i7-8705G CPU and an AMD radeon RX Vega GL discrete graphics card. I can't for the life of me figure out how to switch to my discrete card. My system doesn't even register that another graphics provider exists.

$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x48 cap: 0x9, Source Output, Sink Offload crtcs: 3 outputs: 6 associated providers: 0 name:modesetting

There was a post some time back about a similar problem here but sadly this solution no longer seems to work. AMD doesn't even list the drivers for this card on their website so I'm kind of at a loss here.

Looking up the device with lshw at least shows that the hardware is detected

You need vegam firmware, new kernel 4.18 and mesa-utils amdgpu driver for ubuntu 18.04.

Vegam firmware

git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/
sudo cp linux-firmware/amdgpu/*.bin /lib/firmware/amdgpu/
sudo /usr/sbin/update-initramfs -u -k all

Kernel 4.18

See this application to install new kernel. https://github.com/teejee2008/ukuu

sudo apt-add-repository -y ppa:teejee2008/ppa
sudo apt-get update
sudo apt-get install ukuu

Run the ukuu application and install kernel 4.18.17 or most recent one.

Mesa-utils Driver

sudo add-apt-repository ppa:ubuntu-x-swat/updates
sudo apt-get update
sudo apt install mesa-utils

After reboot, to verify if the vega gl is switchable, run the following command.

env DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
  • Oh my god thank you. I was losing my mind trying to solve this issue. I was thinking I might have to return this laptop! – Defunked-Melon Nov 11 '18 at 16:54
