So I bought this 2018 Acer Aspire 5 laptop with AMD A12 APU, featuring, according to
Code: Select all
xrandr --listproviders
And the reason I made this thread is because I just can't turn on my dedicated graphics card (AMD Radeon RX540).Providers: number : 2
Provider 0: id: 0x79 cap: 0x9, Source Output, Sink Offload crtcs: 3 outputs: 2 associated providers: 1 name:AMD Radeon R7 Graphics @ pci:0000:00:01.0
Provider 1: id: 0x44 cap: 0x6, Sink Output, Source Offload crtcs: 5 outputs: 0 associated providers: 1 name:Radeon 500 Series @ pci:0000:03:00.0
I've asked away on Ubuntu, talked to a few people on Hexchat and I was pointed to very old forum threads when the fglrx and radeonsi drivers were around.
But mine is using amdgpu, so I'm afraid the solution differs a little. In other words, I need an updated solution to this issue.
Here are a few details I believe could help:
If I do
Code: Select all
echo ON > /sys/kernel/debug/vgaswitcheroo/switch
Code: Select all
root@rodolfo-Aspire-A515-41G:/home/rodolfo# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:01.0
1:DIS: :DynOff:0000:03:00.0
This 2015 thread https://ubuntuforums.org/showthread.php?t=2304265 suggests to add a parameter to GRUB, which I believe is the only way to go about this situation, but haven't tried it myself just yet.
For reference, these are my machine's specs:
It goes without saying that, because my dedicated video card is off, my tests with DRI_PRIME=1 are basically just reflecting the results of my integrated video card.root@rodolfo-Aspire-A515-41G:/home/rodolfo# inxi -Fz

Is there away to enable/turn on my dedicated video card? Again, there is no proprietary driver from AMD on this laptop, because they have never ever released a single driver for their own APU series on any Linux Distro, according to their own Download page.
I need this to work, it's the ONLY thing keeping me coming back to Windows when I want to game.
Thank you.
