Before You Begin
A110L: Avoiding Pitfalls for SSD version
Solid state drives are made of flash memory. They are fast in reading but slow in writing data. Flash memory you cannot overwrite countless times. So for a long ssd life take care to
- Never choose to use a journaling file system on the SSD partitions
- Never use a swap partition on the SSD
- Edit your new installation fstab to mount the SSD partitions "noatime"
- Never log messages or error log to the SSD
The rules ensure that we won't reach the maximum limit of writes on our SSD faster than we should.
Choosing Your Installation Media
The Acer Aspire One does not have an optical drive installed on the machine. This means you will need to install Arch Linux through one of the alternative methods:
- USB pen drive (Recommended)
- External USB CD-ROM drive
Installing Arch Linux
- Install through USB media. Press F12 at BIOS post or change boot order with F2.
- It is recommended to permanently add a sd(hc) card into the left sd card reader to extend storage space
Recommended partition shemes for A110L
- /dev/sda1 all 8GB on the SSD for /
- /dev/mmcblk0p1 all space on the extensional left side sd(hc) card /home
- No swap at all
Both card readers work only, when cards are inserted at boot time. Remounting using other cards is then no problem. Be sure to use UUID or LABEL for mounting, as the /dev/mmcbklXpY change names depending on the amount of cards inserted. Assuming you have the left card mounted as /home, the /etc/fstab might have these entries:
# # /etc/fstab: static file system information # # <file system> <dir> <type> <options> <dump> <pass> none /dev/pts devpts defaults 0 0 none /dev/shm tmpfs defaults 0 0 /dev/sda1 / ext2 defaults,noatime,nodiratime,errors=remount-ro 0 1 LABEL=HD-Home /home ext2 defaults,noatime,nodiratime,errors=remount-ro 0 1 #left multi card reader UUID=FFFF-FFFF /mnt/right vfat users,rw,uid=1000,gid=100,fmask=0113,dmask=0002 0 0 #right multi card reader # Temporary folders none /var/log tmpfs defaults,size=10M 0 0 none /tmp tmpfs defaults,size=100M 0 0 none /var/tmp tmpfs defaults,size=20M 0 0 none /var/cache/pacman/pkg tmpfs defaults,size=300MB 0 0
- To set a label on a ext2 filesystem use e2label. On a XFS filesystem use xfs_admin.
- CAUTION: The temporary folders listed above will delete all files in those folders after each reboot.
- CAUTION: Has been reported that the stock kernel is causing partition table corruption on the SD card when you resume from a suspend. Corrupted /home. Someone on the forum suggested that you need a kernel with CONFIG_MMC_UNSAFE_RESUME set to prevent this from happening.
- For more tuning tips see the section "Tuning tips" below.
- Use of kernel >=2.6.26 is recommended to get eth0 up and running
- Blackmask memstick module, makes full load on one core, should be patchable and fixed in next kernel release
- Blackmask ath5k too, since it doesn't work
- Setup cpufreq scaling: load modul acpi_cpufreq and put the wanted governor into rc.local see wiki page
- Modules section example in rc.conf:
MODULES=(!ath5k !memstick r8169 ath_pci acpi_cpufreq)
- use ath_pci for onboard wlan - kernel driver ath5k loads well but does not yet support the chipset
- install madwifi_hal wlan kernel module, for wireless support
Add the following to sysctl.conf to make the wlan blink when there's traffic:
The led on the front will now do the association blink, as well as blink based on wireless traffic. Use ledpin=-3 for a solid light.
- use module r8169 for eth0 support with kernel version >=2.6.26
For having network management mobility you can try the follow packages:
Select one front end from you desktop flavor:
Than add to the /etc/rc.conf "networkmanager" as something similar to:
DAEMONS=(syslog-ng !network !netfs !crond dbus hal @kdm @networkmanager)
Typical Intel HD Audio. Just follow alsa setup
Typical Intel chipset. Works with the xf86-video-intel driver. 400ish on glxgears.
You'll need to install packages
Original Linpus Xorg.conf:

External VGA port
The external VGA port works without further modifications if the externel screen is connected at boot time. If the screen is added later, the VGA port has to be enabled by xrandr. See also section Additional function keys for automating this.
Improve graphics performance
To improve the 2D graphics performance add the following lines to the Driver Section of your xorg.conf
Option "AccelMethod" "exa" Option "MigrationHeuristic" "greedy"
To improve the 3D graphics performance add the following to your /etc/profile
See also Intel Graphics.
Very large fonts may appear in some applications (for example the menu line in Firefox). Setting the DisplaySize in xorg.conf does not help. Instead add the following to your ~/.xserverrc:
#!/bin/bash exec /usr/bin/X -dpi 100
You may also try 75dpi if you can live with small fonts.
Works on the fly with the kernel26 (>=2.6.22) from core using the UVC driver (uvcvideo).
Additional function keys
For the wifi kill switch add these keycodes in /etc/rc.local:
/usr/bin/setkeycodes e055 159 /usr/bin/setkeycodes e056 158
Note that if the wifi kill switch is on (wifi is off), you will need to reboot to re-enable wifi one you disable the kill switch.
For the Fn-Keys add these additionally:
/usr/bin/setkeycodes e025 130 /usr/bin/setkeycodes e026 131 /usr/bin/setkeycodes e027 132 /usr/bin/setkeycodes e029 122 /usr/bin/setkeycodes e071 134 /usr/bin/setkeycodes e072 135
Now setup an ~/.Xmodmap
keycode 160 = XF86AudioMute keycode 174 = XF86AudioLowerVolume keycode 176 = XF86AudioRaiseVolume keycode 223 = XF86Standby keycode 239 = XF86KbdBrightnessDown keycode 123 = XF86KbdBrightnessUp keycode 210 = XF86Display
to your .xinitrc.
If you use KDE or Gnome you can use the appropriate tools to bind the keys or they work just fine without further modifications. If you use neither KDE nor Gnome then read on.
To use the keys to adjust volume it is recommended to use xbindkeys:
pacman -S xbindkeys
to .xinitrc and use the following as .xbindkeysrc.scm:
(xbindkey '("m:0x0" "c:160") "amixer set Master mute") (xbindkey '("m:0x0" "c:176") "amixer set Master 2dB+ unmute") (xbindkey '("m:0x0" "c:174") "amixer set Master 2dB- unmute") (xbindkey '("XF86Display") "uxterm -e vgadisplay.sh")
Note that I have added the option to switch the external VGA output here by a bash-display-script. You will need the following as /usr/bin/vgadisplay.sh:
#! /bin/bash TEMP=/tmp/answer$$ dialog --menu "Select VGA behavior" 13 50 6 1 off 2 1024x600 3 "Auto (most probably 1024x768)" 2>$TEMP ret=$? choice=`cat $TEMP` case $ret in 1) ;; # Cancel - do nothing 0) # User selection case $choice in 1) xrandr --output VGA --off;; 2) xrandr --output VGA --mode 1024x600;; 3) xrandr --output VGA --auto;; esac ;; *) # Shouldnt happen echo "Abnormal ret code from dialog: $ret" ;; esac
You may also bind an xrandr call directly with the XF86Display key but with the above way you have more options.
- Use the noop IO scheduler (elevator=noop to /boot/grub/menu.lst's kernel line)
- While editing the /boot/grub/menu.lst you may also add vga=771 to the kernel line to have a 800x600 256-colored framebuffer for a nicer boot-up. See Grub for more info.
- locate pacman pkg cache in /etc/pacman.conf to your sd card ( /home/where_ever_you_want_it)
- ToDo: post example fstab
- reduce write accesses on / and /home using "noatime" option in /etc/fstab
- speedup logging and tmp files, change /etc/fstab this way:
tmpfs /var/log tmpfs defaults 0 0 tmpfs /var/tmp tmpfs defaults 0 0 tmpfs /tmp tmpfs defaults 0 0
- EXT3: change commit interval in fstab, e.g.:
UUID=f00ba4 / ext3 noatime,nodiratime,commit=15 0 1
- Or for all filesystems use:
echo "1500" > /proc/sys/vm/dirty_writeback_centisecs
- Firefox 3.x uses a sqlite db that creates many write accesses, so this can reduce it:
- Firefox -1- go to about_config, right click, add new string „browser.cache.disk.parent_directory“ with value "/tmp/firefox"
- Firefox -2- change options/security/ and disable phishing - take care !
- ToDo: install customized kernel with slack konfig and custom CLFAGS
- for faster boot and a slack optimized hardware configuration try the custom kernel: http://dev.archlinux.org/~andyrtr/AspireOne/kernel26-one/
if you need additional hardware support recompile it to your needs, report suggestions/missing modules to the forum thread
