tank

A Lenovo ThinkPad X201 Tablet. My first ever ThinkPad, a very useful tool for my studies. It has been my daily driver, on and off, for over a year and a half in total. I really like it when I compute on the go, especially on trains or on mountains (not to be confused with mountain). I now try to bring it with me and use it wherever, just to add to the list on this page.

Alpine setup

wsinatra got me interested in Alpine, and I am having issues with Ubuntu 20 on most computers with tank being the worst affected, so I switched to Alpine. Below are some notes on the initial setup process.

• https://wiki.alpinelinux.org/wiki/LVM_on_LUKS
• https://wiki.alpinelinux.org/wiki/Xfce_Setup

1. Go through setup-alpine until the disk prompt, then ^C

2. apk add lvm2 cryptsetup parted haveged e2fsprogs syslinux
   rc-service haveged start
   parted -a optimal
   
   # Inside parted
   mklabel msdos
   mkpart primary ext4 0% 100M
   mkpart primary ext4 100M 100%
   set 1 boot on
   # Check that everything looks right
   print
   quit
   
   haveged -n 0 | dd of=/dev/sda2
   cryptsetup luksFormat /dev/sda2
   cryptsetup luksOpen /dev/sda2 lvmcrypt
   
   pvcreate /dev/mapper/lvmcrypt
   vgcreate vg0 /dev/mapper/lvmcrypt
   lvcreate -L 9G vg0 -n swap
   lvcreate -l 100%FREE vg0 -n root
   # Check that everything looks right
   lvscan
   
   mkfs.ext4 /dev/sda1
   mkfs.ext4 /dev/vg0/root
   mkswap /dev/vg0/swap
   swapon /dev/vg0/swap
   mount -t ext4 /dev/vg0/root /mnt/
   mkdir -v /mnt/boot
   mount -t ext4 /dev/sda1 /mnt/boot
   setup-disk -m sys /mnt/
   
   echo "/dev/vg0/swap\tnone\tswap\tdefaults\t0 0" > /mnt/etc/fstab
   

3. Add cryptsetup and keymap to the features in /mnt/etc/mkinitfs/mkinitfs.conf

mkinitfs -c /mnt/etc/mkinitfs/mkinitfs.conf -b /mnt/ $(ls /mnt/lib/modules/) blkid -s UUID -o value /dev/sda2 > ~/uuid

5. Set the proper UUID in `/mnt/etc/update-extlinux.conf`:

default_kernel_opts="… cryptroot=UUID= cryptdm=lvmcrypt"

Also check this:  

modules=sd-mod,usb-storage,ext4,cryptsetup,keymap,cryptkey,kms,lvm root=UUID=<UUID of /dev/mapper/vg0-root>

6. ```
chroot /mnt/
# This may cause errors on `/boot`, ignore them
update-extlinux
exit
dd bs=440 count=1 conv=notrunc if=/mnt/usr/share/syslinux/mbr.bin of=/dev/sda
cd
umount /mnt/boot
swapoff /dev/vg0/swap
umount /mnt
vgchange -a n
cryptsetup luksClose lvmcrypt
reboot

7. Enable the edge repos in /etc/apk/repositories

8. apk update
   setup-xorg-base xfce4 xfce4-terminal lightdm-gtk-greeter xfce4-screensaver dbus-x11 sudo
   apk add \

   cat <<EOF
   Section "InputClass"
           Identifier      "Keyboard Default"
           MatchIsKeyboard "yes"

   EndSection
   EOF >/usr/share/X11/xorg.conf.d/20-keyboard.conf
   
   adduser -g lucidiot lucidiot
   

9. Use visudo to allow lucidiot and add Defaults insults

10. Edit /etc/conf.d/bootmisc to set wipe_tmp to YES

rc-update del networking boot rc-update del wpa_supplicant boot rc-update del wpa_cli boot rc-update add dbus default rc-update add fuse default rc-update add networking default rc-update add wpa_supplicant default rc-update add cpufreqd default rc-update add tlp default rc-update add bluetooth default rc-update add swap default rc-service dbus start rc-service fuse start rc-service lightdm start

12. Login into XFCE, check everything works

13. `rc-update add lightdm default`
