CPU Frequency Scaling on KDE

[Mewshi]

Is there anything like the CPU Frequency Scaling applet (from GNOME) for KDE 4?

Thanks!

[MarblePanther]

Yep, just right click on the battery icon in the tray and highlight cpu policy.

[Mewshi]

I don't have a battery icon in my system tray :( Do I need to install something for it?

[MarblePanther]

go into synaptic and install guidance-power-manager
(you should already have it on a default install)

[Mewshi]

That isn't all I'm looking for though...
I want it to tell me what frequency the CPU cores are running at...
Also, when I set it to "powersave" it locks the screen until I put my password back in...

[MarblePanther]

Ahhh, I see. Try this in your terminal:

cat /proc/cpuinfo

Oh, and just rest your cursor without clicking over the guidance applet and it will show you the frequency

[Mewshi]

Is there a way I can get it to show me that all the time? That's *exactly* what I want!

[MarblePanther]

Yes, just install conky from synaptic.

It is a system monitor that stays on your desktop background.

Once you install it, create a file called .conkyrc (you need to check show hidden files) in your home folder.

And you need to add a configuration for it in this .conkyrc

This is what I use:


# -- CODYLD -- CONKY
# Check http://conky.sf.net for an up-to-date-list.

# set to yes if you want Conky to be forked in the background
background yes

# X font when Xft is disabled, you can pick one with program xfontsel
#font 5x7
#font 6x10
#font 7x13
#font 8x13
#font 9x15
#font *mintsmild.se*

# Use Xft?

# mpd_password tinker_bell

# Print everything to console?
# out_to_console no

# mail spool
mail_spool $MAIL

# Update interval in seconds
update_interval 3.0

# This is the number of times Conky will update before quitting.
# Set to zero to run forever.
total_run_times 0

# Create own window instead of using desktop (required in nautilus)
own_window yes

# If own_window is yes, you may use type normal, desktop or override
own_window_type normal

# Use pseudo transparency with own_window?
own_window_transparent no

# If own_window_transparent is set to no, you can set the background colour here
# own_window_colour black

# If own_window is yes, these window manager hints may be used
#own_window_hints undecorated,below,sticky,skip_taskbar,skip_pager
own_window_hints undecorated,below,skip_taskbar

# Use double buffering (reduces flicker, may not work for everyone)
double_buffer yes

# Minimum size of text area
minimum_size 280 5

# Draw shades?
draw_shades yes

# Draw outlines?
draw_outline no

# Draw borders around text
draw_borders yes

# Draw borders around graphs
draw_graph_borders yes

# Stippled borders?
stippled_borders 8

# border margins
border_margin 4

# border width

# Default colors and also border colors

# Text alignment, other possible values are commented
#alignment top_left

#alignment bottom_left
#alignment bottom_right
#alignment none

# Gap between borders of screen and text
# same thing as passing -x at command line
gap_x 0
gap_y 0

# Subtract file system buffers from used memory?
no_buffers yes

# set to yes if you want all text to be in uppercase
uppercase no

# number of cpu samples to average
# set to 1 to disable averaging
cpu_avg_samples 2

# number of net samples to average
# set to 1 to disable averaging
net_avg_samples 2

# Force UTF8? note that UTF8 support required XFT
override_utf8_locale no

# Add spaces to keep things from moving about? This only affects certain objects.
use_spacer none

# Allow each port monitor to track at most this many connections (if 0 or not set, default is 256)
#max_port_monitor_connections 256

# Maximum number of special things, e.g. fonts, offsets, aligns, etc.
#max_specials 512

# Maximum size of buffer for user text, i.e. below TEXT line.
#max_user_text 16384

# Timing interval for music player thread, e.g. mpd, audacious
#music_player_interval (update_interval is default)

# variable is given either in format $variable or in ${variable}. Latter
# allows characters right after the variable and must be used in network
# stuff because of an argument

# stuff after 'TEXT' will be formatted on screen

Then add conky to your sessions startup.


EDIT: You'll have to research in google about displaying cpu frequency in conky. I dont recall what the code for it is atm.





EDIT EDIT:







Ahhh, I just remembered, a month from now when kde 4.2 is released there will be a widget included that will display your cpu frequency

[Mewshi]

No, I want something *in* the system tray to do this. Not a separate program that I need to manually check every so often :\

[MarblePanther]

I already mentioned just mouse over the guidance power manager in the tray and it will show you
97370

Also conky sits on your desktop from startup and stays there, but you'll have to research the code in the script for it to display cpu frequency

Also I mentioned when 4.2 comes out there will be a cpu monitoring widget for your desktop

[Mewshi]

Actually, I want it to display it in the bar the whole time... no way to do this?

[MarblePanther]

I'm not aware of anything like that in kde4 as of right now

The widget in upcoming 4.2 can dock in the panel

So just wait a month

[Mewshi]

K, cap'n.

Thanks for your help!
