FreeBSD - what i had to do

edit some network file for dns
chmod a+rwx for bspwmrc
chown omega for ~/.config
sysctl change device from rear to frontal jack for audio
set $LANG correctly (to fix core dump)

for actually good sounding audio (etc/sysctl.conf):
# sound!
hw.snd.default_unit=5 # frontal jack
dev.pcm.%d.bitperfect

#sck_rate: 48000
dev.pcm.0.play.vchanformat=s32le:2.0
dev.pcm.0.play.vchanrate=44100
hw.snd.feeder_rate_quality=4

for copypaste:
install xclip and xsel manually

for nvidia driver:
1. enable linux_load="YES"(?) and nvidia_load="YES" in /boot/loader.conf and enable linux64 kernel module
2. make nvidia-driver port after updating ports
3. this should be /etc/X11/xorg.conf:
Section "Device"
        ### Available Driver options are:-
        ### Values: <i>: integer, <f>: float, <bool>: "True"/"False",
        ### <string>: "String", <freq>: "<f> Hz/kHz/MHz",
        ### <percent>: "<f>%"

        #Option     "ModeSetClearScreen"     # [<bool>]
    Identifier  "Card0"
    Driver      "nvidia"
    BusID       "PCI:1:0:0"
EndSection
4. reboot

for pip: sudo python3 -m ensurepip

for mounting:
gpart show / gpart list

sudo pkg install fusefs-ext4fuse
use ext2fs, load kernel module (/etc/rc.conf) then do
mount -t ext2fs -o ro /dev/ada2s2 /lfs
