Kernel files restoration

Support
1

Hi,

Every time I blacklist nouveau video driver editing
/etc/default/grub

the nouveau’s driver directory at

/lib/modules/4.x.x-desktop-1omv/kernel/drivers/gpu/drm/

is erased!

Why? Is there another way to recover nouveau’s drivers at kernel’s directories than reinstalling kernel with

urpmi --replacepkgs --replacefiles kernel-4.x.x

?

Thanks

Hey,

I never heard of files getting deleted when blacklisted…

Anyway, if files are really vanishing the following is a pretty obvious workaround but maybe it will make your life easier until you get official support from devs:

Install kernel 4.x.y.z
tar cfz /somewhere/4.x.y.z-drm.tgz /lib/modules/4.x.y.z/kernel/drivers/gpu/drm /boot/your-4.x.y.z-initrd.img

Then if you decide you need to restore just do
# tar xf /somewhre/4.x.y.z-drm.tgz -C /
# depmod 4.x.y.z

Hi,

It can be reproduced easily. For a test, I edit /etc/default/grub to insert at the line GRUB_CMDLINE_LINUX_DEFAULT,

xorg.blacklist=radeon

then did

# update-grub2

reboot the machine and the corresponding directory for radeon was erased from,

/lib/modules/4.8.8-desktop-1omv/kernel/drivers/gpu/drm

Thanks for your suggestion Lauro4, but I prefer to recover with

urpmi --replacepkgs --replacefiles
