* '''2010-07-05''' Updated


The [http://eeepc.asus.com/global/ EeePC]  has really taken the sub-compact pc market by storm.  Although the bundled linux installation is interesting, Fedora is more our style.  This page should contain all the needed quirks and notes needed to run Fedora perfectly on the eeePc.

== News ==
Using USB pendrive (at least 1 GB) take a look at the [[FedoraLiveCD/USBHowTo| USB Howto page]]
* '''2008-06-09''' Enriching this wiki page with all fixes found by Duli and members of eeeuser forum.
* '''2008-02-14''' [http://www.redhatmagazine.com/2008/02/14/fedora-eee-pc-eeedora/ Red Hat Magazine: Fedora + Eee PC = Eeedora]


== ACPI State of play==
Using the regular installation DVD may be problematic when putting it on USB flash drives.  Use the livecd versions.
* Fedora 8: Need to compile the asus_acpi module and use the Asus scripts that handle various functions, Volume Up, Volume Down, Wifi On/Off etc.  Asus also provides their OSD code to notify the user that they have pressed a button.
* Fedora 9: ships with a module called eeepc.ko - read the ACPI support in Fedora 9 to get it work.


=== Buttons ===
'''Recommended for resource limited netbooks'''
* Zz/Fn+F1 - Works as expected computer suspends
* Wifi/Fn+F2 - read ACPI support in Fedora 9 to get it work.
* BrtUp/Fn+F3 - Works.  No OSD
* BrtDown/Fn+F4 - Works. No OSD
* SwitchDisplay/Fn+F5 - read ACPI support in Fedora 9 to get it work.


* AP/Fn+F6 - AccessPoint Mode?  I don't think we need this.  I was thinking about making this button use xrandr to switch on and off a scrolling Virtual Display.  This should help if a large dialog box pops up off screen. (Originally this Fn Key was meant to open the task manager)

* Mute/Fn+F7 - Works in Fedora 8 with Asus module. Not working in Fedora 9.
* VolDown/Fn+F8 - Works in Fedora 8 with Asus module. Not working in Fedora 9.
* VolUp/Fn+F9 - Works in Fedora 8 with Asus module. Not working in Fedora 9.

===Easy and automatic way using the livna repository===
Livna-testing has working madwifi drivers


<pre>
===== Hiding the battery broken alert =====
su
This fixes the annoying battery broken alert reported by gnome-power-manager on login. That's a known [https://bugzilla.redhat.com/show_bug.cgi?id=439460 bug]
rpm -ivh http://rpm.livna.org/livna-release-9.rpm
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-livna
</pre>


This will compile a kernel module everytime is necessary... So feel free to update your kernel when fedora team releases updates.
<pre>$ gconftool-2 --type bool --set /apps/gnome-power-manager/notify/low_capacity 0</pre>
<pre>
yum --enablerepo livna-testing install akmod-madwifi
</pre>
On first new kernel boot, it will compile the new kernel module..when finished, reboot and wifi will work! That's all!


===Manual old school way===
===== Brightness Issues =====
''If you want to compile manually the madwifi driver, use the experimental one:''
With some Eee PC's, the brightness setting are either too low, or are sometimes a little inconstant or arbitrary (inconsistent on each boot, eg. high to low/completely off).
If you have issues with this, issue this command to fix it:


First install all necessary packages:
<pre># setpci -s 00:02.0 f4.b=80
<pre>
su
yum install make binutils gcc glibc-devel glibc-headers libgomp patch kernel-headers kernel-devel wget
</pre>
</pre>


Blacklist the ath5k module:
The <code>80</code> represents the desired range for brightness in hexadecimal, where <code>FF</code> allows to maximum brightness. <code>80</code> is about half and is generally ideal but may need to be tweaked to suit one's need.
<pre>
 
echo "blacklist ath5k" >> /etc/modprobe.d/blacklist
Note this is not permanent, so it should be added to rc.local.
</pre>


Look at your modprobe.conf:
File:<code>/etc/rc.d/rc.local</code>
<pre>
<pre>#!/bin/sh
gedit /etc/modprobe.conf
</pre>


Your /etc/modprobe.conf should look like this:
...
<pre>
<!-- Start Atheros Stuff
-->
alias wifi0 ath_pci
alias ath0 ath_pci
options ath_pci autocreate=sta
<!-- End Atheros Stuff
-->
</pre>


Download madwifi-nr-r3366+ar5007 driver:
setpci -s 00:02.0 f4.b=80</pre>
<pre>
wget http://snapshots.madwifi.org/special/madwifi-nr-r3366+ar5007.tar.gz
</pre>


Extract madwifi source code and compile it:
= Hints and alternative software =
<pre>
===== Maximize battery life =====
tar xvf madwifi-ng-r2756-20071018.tar.gz
<ol>
cd madwifi-nr-r3366+ar5007
<li> Use the integrated HPET timer (saves about 30 CPU wake ups per second)
make && echo ok
su -c "make install && echo ok"
</pre>


== Fixes and solutions to common problems ==
Should be used by default.


=== Shut down fix ===
<pre>$ cat /sys/devices/system/clocksource/clocksource0/current_clocksource</pre>
If your EeePC does not entirely shutdown, add the following line to '''/etc/init.d/halt''' (I put right after the "Saving mixer setting" stuff):


<pre>
This should return 'hpet'
su -
gedit /etc/init.d/halt
</pre>


add this line just before the '''# Save random seed''' block
<li> Change IO scheduler to deadline:
Load the module.
<pre># modprobe deadline-iosched</pre>


<pre>
Edit /boot/grub/menu.lst
#Shutdown eeepc fix
modprobe -r snd-hda-intel && echo "snd-hda-intel module removed!"
</pre>


Bug has been reported: https://bugzilla.redhat.com/show_bug.cgi?id=444115
Add 'elevator=deadline' to kernel options.


<pre>$ cat /sys/block/sda/queue/scheduler</pre>
This should return 'noop [deadline] cfq'


=== Wireless resume from suspend fix ===
<li>Run powertop as root and do the recommended changes. Changes do not stick and have to be run again after a reboot.
With madwifi driver, wireless doesn't work when resuming from sleep...but we can fix this issue with this script
<pre># dnf install powertop</pre>


Create the file:
<li> Disable rarely used services
<pre>
su -
gedit /etc/pm/sleep.d/S99wireless
</pre>
and paste this code:
<pre>
#!/bin/sh


case "$1" in
<pre># for s in abrtd atd auditd avahi-daemon ip6tables iscsi iscsid mdmonitor portreserve livesys livesys-late; do echo "chkconfig $s off"; chkconfig $s off; done</pre>
thaw|resume)
{ ip link set wifi0 up ; } 2>/dev/null
;;
*)
;;
esac
exit $?
</pre>


( Please Note that the machine won't suspend if the radio is turned off and the Madwifi driver is still loaded. )
<li>Install Jupiter and Jupiter Support/Eee from [http://sourceforge.net/projects/jupiter/ SourceForge] to add power profiles as well as extra function keys and automatic support for Super Hybrid Engine.


Make the script executable:
Download the latest jupiter and jupiter-support-eee RPM packages from SourceForge.
<pre>
chmod +x /etc/pm/sleep.d/S99wireless
</pre>


=== NetworkManager drop outs fix ===
<pre>sudo dnf clean all
''Not necessary in Fedora 9''
sudo dnf install --nogpgcheck /path/to/jupiter*rpm /path/to/jupiter-support-eee*rpm</pre>
* Works well with the Madwifi-NG drivers.  To solve problems with frequents drop outs and communication problems try issuing this command.
<pre>
iwpriv ath0 bgscan 0
</pre>
* Just a quick update on a better way to issue this command on every boot.  Edit your /etc/modprobe.conf and change change your lines for ath0 to look like this.
<pre>
alias ath0 ath_pci
install ath_pci /sbin/modprobe --first-time --ignore-install ath_pci && { /sbin/iwpriv  ath0 bgscan 0 > /dev/null 2>&1 || :; }
</pre>


=== Internal Mic not working fix ===
</ol>
Double leftclick the volume icon
Open preferences and enable e-Mic and e-Mic Boost.
In options select input source: e-Mic


(strange, i-mic and e-mic are inverted!)
===== Maximize performance =====


=== TouchPad tap fix ===
To fix the lack of TouchPad tap in Fedora 9, just install the Synaptics package available [http://www.ocf.berkeley.edu/~bobk/packages/ HERE]


''Old solution'' (I think this is for Fedora 8, please specify)
<ol>
To enable the touchpad tapping, make your /etc/X11/xorg.conf look [http://forums.fedoraforum.org/showpost.php?p=1012733&postcount=16 like this] .
<li> Noatime for hard drive (reduces writes to disk)


== Hints and alternative software ==
<pre>nano /etc/fstab</pre>


===Openbox as window manager===
Add ",noatime,nodiratime" after "defaults" for all ext2,ext3,ext4 partitions.
Do yourself a favor and install [http://icculus.org/openbox/index.php/Main_Page Openbox] .
<pre>
yum install openbox obconf
</pre>


After installation you will need to choose openbox as your new window manager.
<li>Remove Pulseaudio (when playing music or watching video pulseaudio can raise CPU usage high)
If you are running gdm click on the session button and choose Gnome/Openbox.  If
you have an .xinitrc that is run at log in you can add, openbox, openbox-session
or openbox-gnome-session to it.


Why?
<pre># dnf remove pulseaudio</pre>
* This Window Manager is FAST!!!
* The decorations are very small and simple.
* By default Openbox trys to shrink windows to fit the viewable screen
* Did I say this how fast this WM is?


===Firefox 3, really a cpu eater===
Switch audio preferences to ALSA. Video players also need to be changed to ALSA in audio properties.
Use Epiphany instead of Firefox 3... it's slim (written using the GTK libs) fast as firefox 3, same compatibility (uses gecko as rendering engine).


<li>Turn off unnecessary services on start up.


Should usually be found in Preferences -> Startup

  • not supported by default, no packages in rpmfusion, no drivers in staging tree. This is a Realtek RTL8192SE chip, incompatible with RTL8192E and RTL8192SU drivers already in staging.
  • vendor-supplied free drivers may or may not work, depending on your kernel version and system CPU architecture
  • you may have luck with a rtl8192se_linux_2.6.0010.1116.2009 driver on 2.6.31.5 or 2.6.31.9 kernel on x86_64 architecture.

Fixes and solutions to common problems

FN keys not working

eeepc_laptop is not loaded. Edit /boot/grub/menu.lst. Add 'acpi_osi=Linux' to the kernel options. 

# lsmod|grep eee

eeepc_laptop should be listed in the results.


Hiding the battery broken alert

This fixes the annoying battery broken alert reported by gnome-power-manager on login. That's a known bug 

$ gconftool-2 --type bool --set /apps/gnome-power-manager/notify/low_capacity 0
Brightness Issues

With some Eee PC's, the brightness setting are either too low, or are sometimes a little inconstant or arbitrary (inconsistent on each boot, eg. high to low/completely off). If you have issues with this, issue this command to fix it: 

# setpci -s 00:02.0 f4.b=80

The 80 represents the desired range for brightness in hexadecimal, where FF allows to maximum brightness. 80 is about half and is generally ideal but may need to be tweaked to suit one's need.

Note this is not permanent, so it should be added to rc.local.

File:/etc/rc.d/rc.local 

#!/bin/sh

...

setpci -s 00:02.0 f4.b=80

Hints and alternative software

Maximize battery life
  1. Use the integrated HPET timer (saves about 30 CPU wake ups per second) Should be used by default. 
    $ cat /sys/devices/system/clocksource/clocksource0/current_clocksource

    This should return 'hpet'

  2. Change IO scheduler to deadline: Load the module. 
    # modprobe deadline-iosched

    Edit /boot/grub/menu.lst

    Add 'elevator=deadline' to kernel options. 

    $ cat /sys/block/sda/queue/scheduler

    This should return 'noop [deadline] cfq'

  3. Run powertop as root and do the recommended changes. Changes do not stick and have to be run again after a reboot. 
    # dnf install powertop
  4. Disable rarely used services 
    # for s in abrtd atd auditd avahi-daemon ip6tables iscsi iscsid mdmonitor portreserve livesys livesys-late; do echo "chkconfig $s off"; chkconfig $s off; done
  5. Install Jupiter and Jupiter Support/Eee from SourceForge to add power profiles as well as extra function keys and automatic support for Super Hybrid Engine. Download the latest jupiter and jupiter-support-eee RPM packages from SourceForge. 
    sudo dnf clean all
sudo dnf install --nogpgcheck /path/to/jupiter*rpm /path/to/jupiter-support-eee*rpm
Maximize performance
  1. Noatime for hard drive (reduces writes to disk) 
    nano /etc/fstab

    Add ",noatime,nodiratime" after "defaults" for all ext2,ext3,ext4 partitions.

  2. Remove Pulseaudio (when playing music or watching video pulseaudio can raise CPU usage high) 
    # dnf remove pulseaudio

    Switch audio preferences to ALSA. Video players also need to be changed to ALSA in audio properties.

  3. Turn off unnecessary services on start up. Should usually be found in Preferences -> Startup
