Troubleshooting Arch Linux

After an update interruption the screen of my Laptop stopped working.

I found the USB ISO of my initial Arch Linux installation and booted into the live environment:

Arch Linux tty:

bash 
1

root@archiso ~ #

Enable wireless connection (WIFI)

(run commands one by one)

bash 
1
2
3
4
5
6

iwctl
device list
station wlan0 scan
station wlan0 get-networks
station wlan0 connect "SSID"
exit

Access your system

List block devices:

bash 
1

lsblk

Result:

nvme0n1     259:0    0 476.9G  0 disk 
├─nvme0n1p1 259:1    0   100M  0 part /boot/efi
├─nvme0n1p2 259:2    0     8G  0 part [SWAP]
└─nvme0n1p3 259:3    0 468.8G  0 part /

Mount your root partition:

bash 
1

mount /dev/nvme0n1p3 /mnt

Access your root partition:

bash 
1

arch-chroot /mnt

Troubleshoot something…

When you finished:

bash 
1
2

exit
reboot
