Re: KMScon vs. AMD Radeon

[pelzflorian (Florian Pelz)]

This is interesting.  I presume if you add modprobe.blacklist=radeon
to the kernel commandline, your system is degraded, e.g. the
resolution is lower?  The installer probably would have a lower
resolution, too, when booting it with modprobe.blacklist=radeon?  Or
maybe the radeon kernel module is not used at all?

Are you using current linux-libre or are you using an old kernel?

lspci reports my card as Radeon R7 240/340.  According to Wikipedia
this GPU was released in 2013.  Xorg attempted to load the radeon
driver and not amdgpu.
