AZF

A Samsung N150 Plus netbook that I plan to mainly use to mess around with Windows, but also as a very portable computer for any smol computing needs or as a backup.

As it will mainly run Windows, it shall be named after an industrial disaster, like my other Windows systems. AZF is a factory in Toulouse where 300 tons of ammonium nitrate exploded on September 21, 2001.

Setup

The drive is split into three partitions:

Windows XP, 110GB
Windows 7, 110GB
Alpine, 36GB

Windows XP

A Windows XP Pro SP3 install, in French. I first tried to transfer the partition directly from LUBRIZOL, but I could never get the system to work properly afterwards, so I started over from scratch.

Windows 7

A completely normal Windows 7 install disk has been used to install Windows 7 Ultimate x64 in French with various updates already installed, as well as .NET 4.6.1.

Alpine

This was set up using the Alpine Standard 3.20.3 ISO.

The main disk was already formatted. /dev/sda4 is intended to hold Alpine, and /dev/sdc is a USB drive with a single /dev/sdc1 partition, intended to hold the MBR and boot partition.

Initial fluff

Run setup-alpine
Use fr-oss as the keyboard variant
Set azf-alpine as the hostname
Configure wlan0 with DHCP
Use busybox as the NTP client
Create a lucidiot non-root user
Do not install an SSH server
Enable the community repo
Auto-detect the fastest mirror
Hit ^C

LVM on LUKS

Install the tools for the LVM on LUKS setup: apk add lvm2 cryptsetup parted e2fsprogs mkinitfs
Format the LUKS partition: cryptsetup luksFormat /dev/sda4
Mount it: cryptsetup luksOpen /dev/sda4 lvmcrypt
Create the LVM physical volume: pvcreate /dev/mapper/lvmcrypt
Create the LVM volume group: vgcreate vg0 /dev/mapper/lvmcrypt
Add a swap logical volume large enough to support hibernation: lvcreate -L 3G vg0 -n swap
Add a root logical volume: lvcreate -l 100%FREE vg0 -n root
Format the swap logical volume: mkswap /dev/vg0/swap
Format the root logical volume: mkfs.ext4 /dev/vg0/root
Format the boot partition on the USB drive: mkfs.ext4 /dev/sdc1
Mount the root logical volume: mount -t ext4 /dev/vg0/root /mnt/
Mount the boot partition: mkdir /mnt/boot && mount -t ext4 /dev/sdc1 /mnt/boot
Activate the swap partition: swapon /dev/vg0/swap

Install

Install Alpine: setup-disk -m sys /mnt/
Append /dev/vg0/swap\tswap\tswap\tdefaults\t0\t0 to /mnt/etc/fstab
Check that cryptsetup, keymap and usb are in the features of /mnt/etc/mkinitfs/mkinitfs.conf
Build the initial RAM disk: mkinitfs -c /mnt/etc/mkinitfs/mkinitfs.conf -b /mnt/ $(ls /mnt/lib/modules/)

MBR

Install Syslinux: apk add syslinux
Check that cryptroot=<LUKS UUID> cryptdm=lvmcrypt is set default_kernel_opts in /mnt/etc/update-extlinux.conf
The UUID of the LUKS partition can be obtained with blkid -s UUID -o value /dev/sda4
Check that cryptsetup,keymap,lvm are in the modules in /mnt/etc/update-extlinux.conf
Build the MBR: chroot /mnt/; update-extlinux; exit
Ignore the cannot find device for path /boot warning.
Unmount the boot partition: umount /mnt/boot
Write the MBR: dd bs=440 count=1 conv=notrunc if=/mnt/usr/share/syslinux/mbr.bin of=/dev/sdc
Make the boot partition bootable: fdisk /dev/sdc; a; 1; w

Reboot cleanly

cd
umount /mnt/boot
swapoff /dev/vg0/swap
umount /mnt
vgchange -a n
cryptsetup luksClose lvmcrypt
reboot

sed -i 's/xdg-screensaver.*$/i3lock/' /home/lucidiot/.config/lxqt/globalkeyshortcuts.conf

Troubleshooting

Screen backlight control

To get the backlight keys (Fn + Up and Fn + Down) to work under Windows:

Install Samsung Easy Display Manager. This works on both Windows XP 32-bit and Windows 7 64-bit.
If you have the Intel GMA 3150 drivers installed, backlight control still may not work. To solve this, apply the following registry edit (source):
```
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000] 
"FeatureTestControl"=dword:00000084
```
Revert this change by resetting the value to 0x184 instead of 0x84.

Under Linux, brightnessctl can handle this perfectly fine. LXQt’s default brightness management does not seem to like though, so you will need to update the shortcut keys for brightness management to use brightnessctl.
