Basic informations about that laptop. Some parameters may be diffrent
 
 
 
=Hardware=
 
'''Processor:''' Intel Celeron M 440 @ 1.86
 
 
 
'''Video:''' Intel Corporation Mobile 915GM/GMS/910GML Express Integrated Graphics Controller (rev 03)
 
 
 
'''Audio:''' Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
 
 
 
'''Wired NIC:''' Broadcom Corporation BCM4401-B0 100Base-TX Ethernet (rev 02)
 
 
 
''' Wireless NIC:''' Broadcom Corporation Dell Wireless 1390 Wlan Mini-PCI Card  (ref 01)
 
 
=Kernel=
 
On default kernel everything seems to be ok, but if you want to hibernate you need kernel23-suspend2
 
 
 
=Networking=
 
Ethernet works fine
 
==Wireless==
 
For my Broadcom i use Ndiswrapper. Drivers are [[ftp://ftp.work.acer-euro.com/notebook/extensa_5200/driver/Wireless%20Lan%20Driver%20802bg%20Broadcom%20Ver.4.2.2.7.zip here]].
 
 
 
In the fact, you need only two files, bcmwl5.inf and bcmwl5.sys. You can download it [[http://cave0.tl.krakow.pl/~ert16/bcmwl5.tar.bz2 here]] , that's LESS THEN ONE MEGABYTE!!
 
 
 
Just install ndiswrapper
 
# pacman -S ndiswrapper ndiswrapper-utils
 
Remove module from your existing kernel
 
# rmmod bcm43xx
 
download and extract drivers and install them
 
# wget http://cave0.tl.krakow.pl/~ert16/bcmwl5.tar.bz2
 
# tar -jxf bcmwl5.tar.bz2
 
# cd bcmwl5
 
# ndiswrapper -i bcmwl5.inf
 
you can test driver by using
 
# iwlist  wlan0 scan
 
wlan0    No scan results
 
 
 
=Power Management=
 
==ACPI==
 
Just install acpid and acpitool
 
#pacman -S acpid acpitool
 
and add it to daemons in /etc/rc.conf
 
DAEMONS=( acpid )
 
now everything should work fine. After reboot you can check it by
 
$ acpitool
 
  Battery #1    : charged, 100.0%
 
  AC adapter    : on-line
 
  Thermal zone 1 : ok, 46 C
 
  Thermal zone 2 : ok, 46 C
 
 
 
==CPU frequency scaling==
 
Works by default width KDE manager, but I preffer cpufreqd
 
install cpufreqd and cpufrqutils.
 
#pacman -S cpufrequtils cpufreqd
 
If you are using XFCE you may want plugin that shows your courrent cpu frequency.
 
#pacman -S xfce4-cpufreq-plugin
 
Now, load your kernel-module that will manage your cpu, for me this will be p4_clockmod
 
#modprobe p4_clockmod
 
check if it runs correctly
 
#cpufreq-info
 
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
 
Report errors and bugs to linux@brodo.de, please.
 
analyzing CPU 0:
 
  driver: p4-clockmod
 
  CPUs which need to switch frequency at the same time: 0
 
  hardware limits: 233 MHz - 1.87 GHz
 
  available frequency steps: 233 MHz, 467 MHz, 700 MHz, 933 MHz, 1.17 GHz, 1.40 GHz, 1.63 GHz, 1.87 GHz
 
  available cpufreq governors: ondemand, conservative, performance
 
  current policy: frequency should be within 1.87 GHz and 1.87 GHz.
 
                  The governor "performance" may decide which speed to use
 
                  within this range.
 
  current CPU frequency is 1.87 GHz.
 
now, configure cpufreqd, that will change your cpufreq governor and other settings when you plug out your AC, or your battery will be low.
 
Edit /etc/cpufreqd.conf and uncomment lines
 
[acpi]
 
acpid_socket=/var/run/acpid.socket
 
[/acpi]
 
And make it quiet
 
verbosity=0
 
If you want to change settings by cpufreqd-set, uncomment lines
 
enable_remote=1
 
remote_group=root
 
Now, you can lunch daemon up and check if it is working correctly
 
#/etc/rc.d/cpufreqd start
 
If everything works change your system settings.
 
Edit /etc/rc.conf, and add module p4_clockmod to the list of preloaded modules
 
MODULES=( p4_clockmod )
 
and add daemons to the list at the end of the file
 
DAEMONS=( acpid cpufreqd  )
 
On XFCE right-click on you panel and add monitor to see informations about your current CPU speed.
 
 
 
==Hibernate==
 
Follow the manual about [[Suspend to Disk]]
 
 
 
After configuration uncomment
 
Runi915resolution yes
 
 
 
=Xorg=
 
install 915resolution by
 
pacman -S 915resolution
 
edit /etc/conf.d/915resolution and insert lines
 
MODE="38"
 
RESOLUTION="1280 800"
 
Add 915resolution to startup scripts in /etc/rc.conf
 
DAEMONS=( 915resolution )
 
Before you start binding your special keys you need set keymap.
 
My keymap is [[Acer_Extensa_5200/keymap|Here ]]. You need save it in the file, and load when you start Xorg.
 
xmodmap keymap
