Well, the drm (nvidia/amd/..) kernel modules are all installed with a single kernel package so you can only decide which to install by building your own kernel package. Blacklisting is the only way to force them not to load. But I assume you know that, since you're using Debian/Devuan already :) Maybe another thing: Since the W4100 seems to use the Cap Verde / Souther Island GPU kind (Can you confirm this, using lspci -l e.g.?) you have the option of using two different kernel drivers with a recent linux kernel: - radeon: this is the older/mature one (the default one) - amdgpu: this is the newer one which might have flaws with SI chipset You can choose them by setting some kernel module parameters (I did this, through /etc/default/grub recently to try something) And maybe a clarification: The graphics driver is divided into two parts: the kernel module and the xorg driver. The xorg driver in beowulf should be able to play with both kernel drivers, I think the amd proprietary xorg driver only works with the amdgpu kernel module. > @Andreas I decided to install a dedicated AMD workstation graphics card, > since I only do workstation stuff on my Thinkstation 😉 > > I prefer a very stable signal over high performance. Did you observe any difference? I mean, the transmission of data between graphics card and display should be digital nowadays. (I owned a FireGL2 a long while ago but remind only the negative aspects of it) cheers Andreas
