Acer Extensa 5200
Basic informations about that laptop. Some parameters may be diffrent
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)
On default kernel everything seems to be ok, but if you want to hibernate you need kernel23-suspend2
Ethernet works fine
See Broadcom wireless.
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
check if it runs correctly
#cpufreq-info cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006 Report errors and bugs to email@example.com, 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
If you want to change settings by cpufreqd-set, uncomment lines
Now, you can lunch daemon up and check if it is working correctly
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.
Follow the manual about Suspend to Disk
After configuration uncomment
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 Here . You need save it in the file, and load when you start Xorg.
