## Remove unused packages
|
|
|
|
Make sure to use the `-Rs` flag when removing. This will clean up deps.
|
|
|
|
```bash
|
|
pacman -Rs package
|
|
```
|
|
|
|
To see a list of packages that are orphaned you can run:
|
|
|
|
```bash
|
|
pacman -Qtdq
|
|
```
|
|
|
|
To remove those packages you can run
|
|
|
|
```bash
|
|
pacman -Qtdq | pacman -Rns -
|
|
```
|
|
|
|
## Update Grub
|
|
|
|
1. `grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=BOOT`
|
|
1. `cp /boot/EFI/BOOT/grubx64.efi /boot/EFI/BOOT/bootx64.efi`
|
|
|
|
## Downgrading Kernel
|
|
|
|
You can find old kernel versions at <https://archive.archlinux.org/packages/l/linux/>
|
|
|
|
You can find old kernel-header versions at <https://archive.archlinux.org/packages/l/linux-headers/>

If you want to downgrade to a previously installed kernel you can use pacman cache:
|
|
|
|
1. `cd /var/cache/pacman/pkg`
|
|
2. `pacman -U linux-x.x.x.arch1-1-x86_64.pkg.tar.zst linux-headers-x.x.x.arch1-1-x86_64.pkg.tar.zst`
|
|
3. `reboot`
|
|
|
|
If you want to downgrade to a kernel that wasn't previously installed:
|
|
|
|
1. Download linux... and linux-headers... from above
|
|
2. `pacman -U linux-x.x.x.arch1-1-x86_64.pkg.tar.zst linux-headers-x.x.x.arch1-1-x86_64.pkg.tar.zst`
|
|
3. `reboot`
|
|
|
|
