Re: How do I change the grub kernel boot parameters in F32 ?

Thank you for sharing that !   Here is my /etc/default/grub.  It blacklists the nouveau driver.

How do I tell how my computer is booting (UEFI or not) and how do I set up the parameters if its booting UEFI ?

GRUB_TIMEOUT="5"
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT="saved"
GRUB_DISABLE_SUBMENU="true"
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1 rd.lvm.lv=fedora/ro>
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG="true"

        This is pretty interesting because I am trying to fix a
          problem caused by transitioning from nouveau drivers to the
          Nvidia drivers.  I installed the Nvidia drivers but my system
          continues to boot the nouveau drivers.   If I blacklist the
          nouveau drivers, my system boots and runs the Nvidia drivers
          just fine.   The kernel parameters I want to add are for
          blacklisting the nouveau driver.  (See above).

            I just installed Fedora 32 on a machine 2 days ago, and had
            to install

            the nvidia drivers because nouveau kept crashing (alas!).  I
            installed

            the rpmfusion akmod-nvidia package, and the corresponding
            kernel entry

            has this:

            options $kernelopts

            So it looks like the grubby issue has been fixed.

            -- 

    So far this setup still works for a legacy non-efi boot

    /etc/default/grub

    GRUB_TIMEOUT=15

    GRUB_DISTRIBUTOR="Fedora"

    GRUB_DEFAULT="Windows 10 (loader) (on /dev/sda1)"

    GRUB_GFXMODE=1280x1024x32

    GRUB_GFXPAYLOAD_LINUX=keep

    GRUB_CMDLINE_LINUX="rd.md=0 rd.lvm=0 rd.dm=0 SYSFONT=True 
    KEYTABLE=us rd.luks=0 LANG=en_US.UTF-8 vga=791 "

    GRUB_THEME="/boot/grub2/themes/system/theme.txt"

    # GRUB_THEME=/boot/grub2/themes/starfield/theme.txt

    GRUB_ENABLE_BLSCFG=true

    Have yet to get the gfxmode line to do anything with the grub
      screen though.
