You don't mention how you do so on boot. I assume you're talking about adding=20 =E2=80=98modprobe.blacklist=3Dnouveau[,=E2=80=A6]=E2=80=99 to the kernel co= mmand line[0] in=20 GRUB. You can easily ask[1] Guix to add it to the default kernel command=20 line at each boot, like so: (operating-system [=E2=80=A6] (kernel-arguments (cons* "modprobe.blacklist=3Dnouveau[,=E2=80=A6]" [=E2=80=A6] %default-kernel-arguments)) [=E2=80=A6]) Don't forget to reconfigure and optionally reboot. > My second question is about the hda-intel sound driver.=20 > I have hda-intel and nvidia-hdmi sound modules.

You forgot to mention how you'd use /etc/modprobe.d to do so=E2=80=A6 ;-)=20 So here too I can only guess an answer. If you just want to add default module options, you can do so on=20 the kernel command line as well: either manually in GRUB (to test)=20 or the kernel-arguments field mentioned above. For a random example plucked from =E2=80=98modinfo snd_hda_intel=E2=80=99: = to=20 disable power saving, simply add "snd_hda_intel.power_save=3D0", and=20 the kernel will set this option for you whenever snd_hda_intel is=20 loaded, no matter when or how or who loads it.
