+
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
+
