Hi guys,

Currently the udev package ships

/lib/modules.d/framebuffer_blacklist.conf

This file blacklists all the framebuffer modules present on the build machine. This does not feel quite right to me, and it is not exactly self-documenting what bug is being fixed.

If possible, I'd like to drop this file and add more specific blacklisting where needed. If I understand correctly, the main issue is in the case where proprietary drivers are used (nvidia / catalyst) and the opensource drivers are loaded instead. If this is the only problem, I'd like to propose we solve it as follows:

Add

/lib/modules.d/nvidia.conf: blacklist nouveau blacklist nvidiafb

to the nvidia package (and analogously to the catalyst package in aur).

instead of trying to avoid such issues, why not drop most of framebuffers from kernel instead? that's a more logical step. for example, fedora only has enabled in his kernel: config-generic:CONFIG_VIDEO_FB_IVTV=m config-generic:CONFIG_FB_I810=m config-generic:CONFIG_FB_I810_GTF=y config-generic:CONFIG_FB_I810_I2C=y config-generic:CONFIG_FB_TILEBLITTING=y config-generic:CONFIG_FB_VESA=y config-generic:CONFIG_FB_VGA16=m config-generic:CONFIG_FB_VIRTUAL=m config-generic:CONFIG_FB_VOODOO1=m config-generic:CONFIG_FB_EFI=y config-generic:CONFIG_FB_UDL=m

This is exactly what /lib/modules.d is for, so it makes a lot of sense to me. Are there any other use-cases I have missed?

I'll push an udev package with this change to staging shortly, so people can try it out if they wish.

Cheers,

Tom
