Details

Description: Disabling the kernel config CONFIG_FB_UVESA breaks v86d and makes the latest kernel incompatible with the Intel GMA3600 graphics adapter, which requires this mode to function properly.


Additional info:
* 4.15.5
* # CONFIG_FB_UVESA is not set


Steps to reproduce: add v86d hook to mkinitcpio.conf and build initramfs image. The build breaks.

If it makes your decision any easier, I've created a uvesafb-dkms github project and have the PKGBUILD, dkms.conf and .SRCINFO files required for an AUR package. I've tested it and it works as expected. However, I have no idea how to create an AUR project/package - assistance is required if you'd prefer to go this route.

It isn't hard to do that, but IRC and/or forum are better suited for that.

You can post the PKGBUILD in the "AUR Issues, Discussion & PKGBUILD Requests" subboard asking for review and help with submitting.

I already created a uvesafb-dkms AUR project. It includes the uvesafb driver and v86d.
