Hi everyone, Since I wanted to know how all things are working out between FreeBSD, = DRM and Linux, I skimmed through the source and tested a lot with FBSD13 = running in Virtual Box 6.x on FBSD13 host. Now I fixed the Makefiles and = found the issue for the kernel panic which happens directly after = loading the vbox DRM driver. Within X11 everything looks now okay, multiple monitors as well as = different resolutions work, but in the console there is still a bug = making it unusable: You can=E2=80=99t see any output, the console is frozen. If you force = the repaint of the virtual machine window (moving other windows around = or open the =E2=80=9Eabout dialog=E2=80=9C of Virtual Box), the output = is drawn. So console works, but the framebuffer output seems to have = issues. Do you have an idea where I could look to fix this issue? Is there any = more documentation on how DRM works? Also, how should I provide the fix? Diff here in the list, or PR in = Github? Best, Alexander
