for klaptop, you have to first configure it. set everything to conservative,
it should raise your processor speed based on your needs. be sure also to
add cpufrequtils as a service at boot and to load the eventual modules at
boot time by adding them to the /etc/modules.autoload/kernel-2.6 so that
they load at boot. without cufrequtils and the modules (if you've build the
stuff as modules and you've done it if you've used my config) you won't be
able to switch. without rebooting you could open konsole and start
cpufrequtils with /etc/init.d/cpufrequtils start and then add it with
rc-update add cpufrequtils default and then modprobe cpufreq_powersave &&
modprobe cpufreq_conservative && modprobe cpufreq_performance. now you
should be able to switch them with klaptop. don't use kpowersaved since it
doesn't work anymore or at least on my pc it cannot find acpid started.
if you'd like a monitor for kde there are different solutions:
- one is superkaramba with some theme like aero-aio
- kima which is directly included into the kicker as an applet and can
monitor thermal, processor temp, processor load, uptime, battery and
processor and /proc speed. i prefer this solution since it's faster to see
and never gets covered by apps letting me see always the state of the
system.
for lm_sensors instead, is quite ok to not have fan control since the fan on
a notebook is not usually connected to some control sensor but is controlled
directly by acpi. on notebooks usually you might find some monitor for cpu
core, for some removable media like pccards and nand devices like mmd. the
only thing that is useful is the core processor monitor which gives you the
temp of the core(s) and it lets you have an idea of how your processor works
. remember that thermal temp might be different and usually is higher than
core temp.
also some helpful utils for kde are: klipper (fabulous klipboard); kompose
(osx kompose changer), ksynaptic (if you have synaptic or alps touchpads
that usually get installed in notebooks), knetworkmanager + networkmanager
and the new kde4 like kicker that includes a built-in search module that
improves usability of kde. other useful kicker applets are the shutdown and
block applets, the kmixer applet (this lets you remove from start kmix), the
show desktop applet and the trash can applet.
also for full kde experience i suggest kaffeine + xine (not 1.1.10 since it
has some problems with external linkage) and amarok + xine. install xft and
cairo with svg and pdf flags and search for the font antialiasing wiki that
was on xeffects if i remember right.
also ksplash-engine-moodin is wonderful for personalizing the ksplash and
oxy-cursors from flameeyes-overlay are wonderful cursor themes.
if you like osx be sure to search for a baghira how to and on how to make
kde identical to osx (don't use kxdocker, though). and before using compiz
be aware that ati drivers don't work well with it. for tuning ati drivers
visit phoronix forums and you'll have a lot of info about them.
