Acer Travelmate 240 - CPU Frequency Scaling
Na notebooku Acer Travelmate 240 sa pokusam robehnut frequency scaling. Nasiel som si pekny navod:
http://www.freewebs.com/duckzland/t240.html
Ktory spociva v (je to pre fedoru 4, pricom ja tam mam zenwalk4):
The Acer Travelmate 240 turns out to have 9 stepping of CPU frequency, If you are using kernel 2.6 (Fedora Core 4 standard) then you should have cpufreq kernel module, cpufreq-selector and optional : cpufreq-utils package installed using yum.
To install the CPU frequency, first you will need to load the kernel module :
p4-clockmod
cpufreq_ondemand
cpufreq_powersave
Then use dmesg to check if the module loaded correctly or not. Then you will need to load the gnome CPU frequency applet. After that, issue /usr/sbin/cpufreq-selector -g governor (ondemand, powersave, performance) to set your desired governor.
After successful loading, edit the rc.local to add :
modprobe p4_clockmod
modprobe "desired_governor" (cpufreq_ondemand, cpufreq_powersave)
Otazky:
Aku utilitku pouzijem namiesto "gnome CPU frequency applet"?
Dals som prikaz:
dmesg :a vyplulo mi to: vposlednom riadku:
p4-clockmod: P4/Xeon(TM) CPU On-Demand Clock Modulation available
Ako zistim, ze ktory modul tam je, ktory treba loadnut? A hlavne ako ho loadnut?
Juchúúú! Písmenkujem na lukas.cerro.sk

Rozlisenie monitora 24.12.2006 | 20:26
Lukáš Ubuntu 9.10 Používateľ
Na hore uvedenom notebooku je rozbity hlavny display. Cize vyuzivam len koncovku na externy monitor, kde sa mi stale nejak nedari nahodit rozlisenie 1280x1024. Skusal som nejake editacie xorg.conf, ale no nejak nic. Co teda editovat v nom, aby mi n abehlo 1280x1024? Dakujem P.s. Predchadzajuci problem sa nedari vyriesit nikde. Ta potvora nezhodi frekvenciu nizsie ani na windowse. Tu je moj xorg.conf: # ********************************************************************** # This file was generated by videoconfig (Zenwalk Xorg configuration tool) # If you changed your video card or monitor, please run videoconfig again # from runlevel 3.

Re: Rozlisenie monitora 25.12.2006 | 02:15WlaSaTy Návštevníkodporucil by som pozriet sekciu monitor, frekvencie sice umoznuju dane rozlisenie ale podla ich rozsahu je mala pravdepodobnost ze to pojde. ak by boli ok, tak zrusit edid a v pripade maximalnej krizy to rozsirenie aj zadefinovat. a hlavne skontrolovat logy.

Re: Re: Rozlisenie monitora 25.12.2006 | 11:5255.lukas NávštevníkJa som cumel na nejaky prikaz xrand (alebo nieco take) a podla neho mi to vyplulo ze pri 1280x1024 mi to da len 40Hz. Vo windowse mi to da 1280x1024 pri 75Hz tak by to malo ist, uz to len nejak nastavit.

Re: Re: Re: Rozlisenie monitora 25.12.2006 | 16:58WlaSaTy Návštevníkten prikaz je xrandr a jedna sa o ovladanie rozsirenia pre xwindors ktore umoznuje menit za behu rozlisenie, frekvenciu a orientaciu zobrazovania. vzhladom na to ze system zle zdetekoval pracovny rozsah frekvencii (vid odporucany log z xwindows) alebo je to zle napisane v konfiguraku (vid frekvencny rozsah a DDC), tak je pochopitelne ze to bezi na nizsich rozsahoch ako by malo a tym padom sa aj nejake rozlisenia zrusia. takze co urobime?
