Marco,
Hullo and welcome!
"Marco Menne" via 写道:
I searched a lot in the net but did'nt find an useful answer for
Guix system.
I know to blacklist the nouveau graphics driver on boot but how
can I blacklist it permanentely?
You don't mention how you do so on boot.
I assume you're talking about adding
‘modprobe.blacklist=nouveau[,…]’ to the kernel command line[0] in
GRUB.
You can easily ask[1] Guix to add it to the default kernel command
line at each boot, like so:
(operating-system
[…]
(kernel-arguments
(cons* "modprobe.blacklist=nouveau[,…]"
[…]
%default-kernel-arguments))
[…])
Don't forget to reconfigure and optionally reboot.
My second question is about the hda-intel sound driver.
I have hda-intel and nvidia-hdmi sound modules. On Slackware I
cloud blacklist the Nvidia driver and could get the intel driver
working.
But as in Guix system there is no /etc/modprobe.d/ folder I
don't know how to get my sound working.
You forgot to mention how you'd use /etc/modprobe.d to do so… ;-)
So here too I can only guess an answer.
If you just want to add default module options, you can do so on
the kernel command line as well: either manually in GRUB (to test)
or the kernel-arguments field mentioned above.
For a random example plucked from ‘modinfo snd_hda_intel’: to
disable power saving, simply add "snd_hda_intel.power_save=0", and
the kernel will set this option for you whenever snd_hda_intel is
loaded, no matter when or how or who loads it.
Kind regards,
T G-R
