[SOLVED] There is no /dev/dri/ path

glxgears gave me exactly 60 fps with an amd rx480.

And also, again, the amdgpu package isn't for your chipset.

Also suggested that you load Ubuntu or Mint, both of which are Debian based, but may provide an easier path for you. Good luck.

can you help me about make config for xorg?

i tried `X -configure`s config, startx wont work with it.
also i tried config in https://wiki.debian.org/AtiHowTo Configuration part, startx wont work with it.

i have firmware-linux-nonfree package and i did edit sources.list for add non free repos.

small information about current status:

~$ xrandr --listproviders
Providers: number : 0

~$ DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.9, 128 bits)

EDIT: i did it somehow, now:

~$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x55 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 4 outputs: 2 associated providers: 0 name:KAVERI @ pci:0000:00:01.0

~$ DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Gallium 0.4 on AMD KAVERI (DRM 2.49.0 / 4.9.0-7-amd64, LLVM 3.9.1)

i have /dev/dri now, but is im able to increase fps? like what fps i get in debian 7 with fglrx? (difference is not very big just asking, its acceptable)

how did you get those numbers?

i have debian 7 setup in other disk, im able to try anything in debian 7 when im in debian 9.
./start_plot3d_windowed_1024x640.sh shows current fps in window bar, i did calculate average for all tests.
glxgears shows current fps in terminal, i did calculate average for all tests.

just a comment:
as I told glxgears reported 60 fps on my ubuntu 18.04 (using default, opensource drivers).
I have now installed the official amd drivers (remember, I have an rx480). Now glxgears reports more than 4000 fps. But the game I tried works exactly the same way (I checked the in-game fps rates).

yeah, in opensource drivers if you want unlock vsync you need open a program with vblank_mode=0 parameter. example:

Code:

vblank_mode=0 glxgears

by the way what game you tried for fps test? i feel like i will get different fps.
