i am still confused:
this: Graphics: Device-1: Advanced Micro Devices [AMD/ATI] Cape Verde XT [Radeon HD 7770/8760 / R7 250X] driver: amdgpu v: kernel. Display: x11 server: X.Org 1.20.8 driver: amdgpu FAILED: ati unloaded: fbdev,modesetting,radeon,vesa. resolution: 1920x1200~60Hz. OpenGL: renderer: AMD Radeon HD 7700 Series (VERDE DRM 3.36.0 5.6.2-1-default LLVM 10.0.0) v: 4.6 Mesa 20.0.4.
this looks for me if there where 6 drivers here: driver: amdgpu FAILED: ati unloaded: fbdev,modesetting,radeon,vesa
driver: indicates the DDX currently active FAILED: is an apparent indicator that the currently active DDX trumped it unloaded: is a list of alternatives that could have been used to run X with the active GPU. fbdev and vesa are low-performance generics incapable of 3D and most widescreen resolutions. modesetting is a newer fundamental X technology that supports most GPUs new enough to have KMS support. With most GPUs, X will use the modesetting DDX if none of xf86-video-* are installed, and can nevertheless use it via specification as explicitly named device driver in /etc/X11/xorg*conf*.
but if i understood you correct, then ati = radeon ??? but if the drivers are same, why is one "unloaded" and the other "failed"
would be nice if you help me to understand......
This is typical misfortune resulting from corporate mergers and acquisitions and consequent name changes. Many moons ago, the company ATI made GPUs in a product line named Radeon. This resulted in ATI and Radeon being functional equivalents in an Xorg context for many moons. A driver package eventually named xf86-video-ati provided a DDX named radeon. Then the company AMD bought the assets of ATI, initially keeping the Radeon product line intact. AMD then developed new technology to replace the Radeon product line. For optimal performance, this naturally required a new DDX. Thus the xf86-video-amdgpu package resulted, providing the amdgpu DDX. At the same time, basic support for the new product line from AMD was maintained in the radeon DDX, and as a matter of sound policy, without any name changing that would trigger massive confusion in the FOSS world. So, either the radeon DDX or the amdgpu DDX could be utilized to run Xorg. Xorg wasn't well equipped to automagically choose which to use. Consequently, the cmdline options radeon.si_support=, amdgpu.si_support=, radeon.cik_support= and amdgpu.cik_support= were developed to assist in correct DDX selection/specification. -- Evolution as taught in public schools is religion, not science.
