CRUX on Acer Aspire One ZG5

this-device

About this device

About May 2021 I bought this device for 20 euros in the second hand market.

I upgraded it to 1.5G of RAM, the maximum capacity it allows and added a 120GB SSD disk for better performance.

Debian 10 worked fine on it but playing youtube videos is only possible at 360p resolution. while CRUX can run at 480p without framedrops.

Specification

  • Processor: Intel Atom N270 1.66 Ghz
  • Motherboard Chipset: Intel 945 GM + CH7M
  • Maximum memory (RAM): 1.5 GB DDR2
  • Graphics Processor: Intel GMA 945GMS
  • Display: TFT 16:09
  • Screen size: 8.9 in
  • 3 x USB 2.0
  • Microphone Jack
  • D-Sub
  • RJ45
  • Headphone Jack
  • Multi-card reader
  • SD slot

Installation

Download the last supported version available for this device. We have to go for the i686 architecture, so then we will use CRUX 3.5 i686 which is still alive thanks to Matt Housh (jaeger).

$ wget https://crux.ninja/i686-iso/crux-3.5-i686.iso
$ wget https://crux.ninja/i686-iso/crux-3.5-i686.md5
$ md5sum -c crux-3.5-i686.md5

Packages

Select all packages from core, opt and xorg and grub2 as the bootloader

Wait until installation finishes

Kernel

Copy kernel sources from the iso

# mount -o loop crux-3.5-i686.iso /mnt
# cp /mnt/crux/kernel/linux-4.19.112.tar.xz /usr/src

Uncompress and prepare kernel sources

# cd /usr/src
# tar xf linux-4.19.112.tar.xz
# ln -s linux-4.19.112 linux

Copy kernel config file config-4.19.112

# wget https://raw.githubusercontent/sepen/crux-on-devices/master/acer-aspire-one/boot/config-4.19.112
# mv config-4.19.112 /usr/src/linux-4.19.112/.config

Build the kernel

# cd /usr/src/linux-4.19.112
# make

Install kernel files

# cd /usr/src/linux-4.19.112
# make modules_install
# cp arch/x86/boot/bzImage /boot/vmlinuz-4.19.112
# cp .config /boot/config-4.19.112
# cp System.map /boot/System.map-4.19.112

Bootloader

Make symlinks using generic names so that the bootloader auto-discovers the config

# cd /boot
# ln -s vmlinuz-4.19.112 vmlinuz
# ln -s config-4.19.112 config
# ln -s System.map-4.19.112 System.map

Create grub config file

# mkdir /boot/grub 
# grub-mkconfig -o /boot/grub/grub.cfg

Xorg

Activate tap to click

$ echo '# Activate "tap to click" on touchpad
Section "InputClass"
	Identifier "libinput touchpad catchall"
	MatchIsTouchpad "on"
	MatchDevicePath "/dev/input/event*"
	Driver "libinput"
	Option "Tapping" "on"
EndSection' | sudo tee /etc/X11/xorg.conf.d/40-libinput.conf

Firefox

ALSA support was dropped starting Firefox 52.0 and later. https://support.mozilla.org/en-US/questions/1209469

I still want to use ALSA and try to avoid pulseaudio as much as possible, so apulse comes to the rescue:

$ sudo prt-get depinst apulse
$ apulse firefox

Openbox

Install imlib2 and rebuild openbox to have icon support

$ sudo prt-get depinst imlib2
$ sudo prt-get update -fr openbox

Install openbox configuration manager

$ sudo prt-get depinst obconf

Install openbox themes. Then apply a theme you desire using obconf

$ git clone https://github.com/addy-dclxvi/openbox-theme-collections ~/.config/openbox/themes
$ obconf

Auto-start openbox when running startx command: ~/.config/openbox/autostart

Show openbox menu when windows key is pressed, Edit ~/.config/openbox/rc.xml and add this code block:

<keybind key="Super_L">
  <action name="ShowMenu">
    <menu>root-menu</menu>
  </action>
</keybind>

Generate openbox menu with obmenu-generator

$ sudo prt-get depinst obmenu-generator
$ obmenu-generator -i > $HOME/.config/openbox/menu.xml

Add a dynamic menu by copying this contents to ~/.config/openbox/menu.xml

<?xml version="1.0" encoding="utf-8"?>
<openbox_menu xmlns="http://openbox.org/"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://openbox.org/">
    <menu id="root-menu" label="obmenu-generator" execute="/usr/bin/obmenu-generator -i" />
</openbox_menu>

Polybar

Install an eye candy status bar: polybar

$ sudo prt-get depinst polybar
$ cp /usr/share/polybar/config.example ~/.config/polybar/config
$ polybar -c ~/.config/polybar/config example
