PowerTOP

July 29, 2009 at 09:27 · Filed under Open Source, Ubuntu

Whenever we need to check which process is consuming most CPU we use the TOP command or HTOP command. Then you can kill processes consuming resources unnecessarily on your GNU/Linux system.

But yesterday I discovered (thanks Marcos) the PowerTOP command:

  • Show how well your system is using the various hardware power-saving features
  • Show you the culprit software components that are preventing optimal usage of your hardware power savings
  • Help Linux developers test their application and achieve optimal behavior
  • Provide you with tuning suggestions to achieve low power consumption

For me the last characteristic is great in order to save battery and power consumption.

By the way…I killed skype (mandatory binary installation, because skype is not OpenSource) since it was devouring my CPU :-)

Fixing skype audio problem on Ubuntu 9.04

July 9, 2009 at 19:55 · Filed under Uncategorized

via this blog I discovered how to be able to use skype without problems in ubuntu 9.04

In spite of not being open source skype is always useful to make private calls to the family :-) Enjoy the solution:

When running Skype on Ubuntu 9.04, you will get the following error message when making a test call:

“Problem with Audio Playback”

The problem is that Ubuntu uses pulse audio and Skype does not play nicely with it. To fix it, do the following:

  1. Open Skype options and select Sound Devices
  2. Change Sound In, Sound Out and Ringing to use “pulse”
  3. Clear the check mark next to “Allow Skype to automatically adjust my mixer levels” (This step may not be required)
  4. Press the Apply button and then the Close button.

You should now be able to place a test call.

Adobe Flash Player problems with fullscreen mode in Firefox and Ubuntu 9.04

July 2, 2009 at 14:28 · Filed under Ubuntu

Since I upgraded to Ubuntu 9.04 (a.k.a. Jaunty Jackalope) I found some problems when watching videos via Flash media player 10 in fullscreen mode.

After doing a small research the *only* solution that really solved the issue is explained in this thread

What you have to do is easy:

  1. sudo mkdir /etc/adobe
  2. sudo nano /etc/adobe/mms.cfg
  3. Paste “OverrideGPUValidation=true” (without quotation marks)
  4. Restart Firefox.

I hope this solves the problem.

I am looking forward to the next Adobe Flash Player release :-)
