[Solved]T weaking KDe for Less Powerful Computers

[AS]

as, I haven't done anything because I am really not sure what to do. 

This is where I am and what I am looking at.  I clicked on the Root in the left panel and found file /etc/sysconfig/cpufreq.  This is what it looks like.

# set cpufreq governor if defined
# possible choices are: ondemand powersave userspace performance
GOVERNOR=ondemand

# minimum frequency
#MIN_FREQ=

# maximum frequency
#MAX_FREQ=

# Uncomment to use acpi-cpufreq as fallback
#USE_ACPI_CPUFREQ=yes

already set "ondemand", then please forget the edit session and apply only the following commands:

chkconfig cpufreq on
service cpufreq start
cpufreq-info

.... it's not what I was expecting ... try the followings:

cpufreq-set -c 0 -g ondemand
cpufreq-set -c 1 -g ondemand
cpufreq-info

... clearly I'm missing something here ... what ?

... clearly I'm missing something here ... what ? 

Don't know - could there be a clue here?

Thank you MtnMan and Hootiegibbon,

the packages actually look like already updated, and the difference I still see are:
the fact the min max frequencies are not specified on ms_meme computer, (though mine work without needing mix and max freq),
and the fact that ms_meme is actually using kernel 2.6.33.7, because the update to the recent kernel 2.6.37.4 and 2.6.38.8 actually doesn't works smoothly on ms_meme machine.

[MtnMan]

I pointed to the link because driver:  p4-clockmod was in common.  Maybe nothing.

Thank you, I will try to find a P4 to perform some test 

This isn't the more important issue, I renew the request about new ideas to decrease the use of RAM memory.

IMO unless ms_meme provides us with a more recent screenshot of her System Activity setting the heading Memory as the primary sort on the table, what else is using the most and can these processes/apps be turned off or not.

I see in mine that X uses the most followed by virtuoso-t, both at over 100M ...

Hi Archie,

it was posted previously, (not sorted): http://www.pclinuxos.com/forum/index.php/topic,96036.msg810709.html#msg810709

The only things I think it could be removed are akonadi and mysqld server ... still have a bit uncertain about ...
squid, sshd, postfix, xfs, snmpd, has been already stopped/disabled...

I haven't been idle.  I took the thing apart and dusted up a bit. Could strangle my mate with the cords.    But got it all back together in one piece.

Ouch! That's a surprise! 


Now, wouldn't you be able to substitute those two RAM modules ?

Ouch!  I feel a wee bit exposed.
