Hi there!
I had a similar problem recently with grub. No idea why it doesnt work.
Try using grubby instead of grub2-mkconfig if you want the system to
keep your kernel parameters between boots.
Something like:
sudo grubby --args="i915.modeset=0 rd.driver.blacklist=i915" --update-
kernel=ALL
Hope it helps!
Have a nice day!

Hi list,
I reinstalled on my workstation CentOS 8.1.
I explain: I'm a KDE user but packages shipped from EPEL currently
are
buggy so I prefer a stable and functioning system to work with. So I
tried to remove KDE workgroup and installed group "Workstation" but
the
system bricked so I reinstalled with GNOME.
I've an nvidia gtx 1050ti GPU so I installed kmod-driver from
rpmfusion.
After the installation of Nvidia driver, I rebooted, gdm start and
after
I perform the login the system freeze. So this problem happened to
me
with C7.5 and nvidia driver. In my case I need to blacklist i915
module
and system works.
Also in this case I tried to boot centos changing grub kernel
parameters
pressing 'e' in the grub menu and adding "i915.modeset=0
rd.driver.blacklist=i915", booted and system works.
So I tried to make this permanent updating grub configuration adding
the
previous directives (and removed rhgb and quiet) to
/etc/default/grub
and run grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg.
Reboot the system and checked again kernel parameters on grub menu
and
seen that nothing changed. Booted and freezed.
I checked /boot/efi/EFI/centos/grub.cfg and kernelops has the new
directives.
Seems that grub configuration does not take effect.
I made another test inside a VM installed with minimal selection and
remove rhgb and quiet parameters and worked fine. The vm is BIOS and
my
workstation UEFI.
How I can solve this problem? Currently to boot my system I need
always
to add this params.
Thank you in advance

Hi,
I tried as suggested, parameters will be updated but I get already
crash. So I tried to remove also rhgb and quiet and works well.
Would be good to know what is wrong with grub2-mkconfig.
Where start to investigate?
