• Using Microphone

Run 

$ alsamixer 

Press F6 select sound card...  Set Mic Boost to 20 and disable Auto-Mute M (use arrow buttons)

Check audio device for capture audio from mic, by

$ cat /proc/asound/devices

  1:        : sequencer

  2: [ 0- 8]: digital audio playback

  3: [ 0- 7]: digital audio playback

  4: [ 0- 3]: digital audio playback

  5: [ 0- 0]: hardware dependent

  6: [ 0]   : control

  7: [ 1- 0]: digital audio playback

  8: [ 1- 0]: digital audio capture

  9: [ 1- 0]: hardware dependent

 10: [ 1]   : control

 33:        : timer

Try record for 20 seconds

$ arecord -f cd -D hw:1,0 -d 20 test.wav

It worked for me, I able to hear myself. 

Graphical "Sound Preferences" looks like not handle the device properly. To use mic with graphical apps you probably have to select the capture device manually.

  

Internet connection sharing with Raspberry Pi via Ethernet

My laptop is connected to internet via WiFi and I want to connect raspberrypi via Ethernet cable. I want to be able connect to raspberrypi via ssh and I also want for raspberrypi to be able access the internet. I have basic understanding about networks. And I think this task should event easier then setup a router. Bud it is not! Unless you know exactly what to do! You can find tips with a million terminal commands... You  can study advanced networks... bridging or nat and then run dhcp server... If you running a server this is all great! On a laptop you do not need all this...

Click Edit!

Change to "Shared to other computers"

Just my local network connection information, no voodoo magic!

First time I set this up! It did not work! Solution is: RESET laptop after configuration is done!

To find out raspberrypi IP:

rolas@Aspire-E5-571G ~ $ cat /var/lib/misc/dnsmasq.leases
1434209461 b8:27:eb:75:89:01 10.42.0.79 raspberrypi ff:eb:75:89:01:00:01:00:01:1c:dd:60:6a:b8:27:eb:75:89:01

Automatic brightness control very very annoying, it dims down almost random, so you have to set it couple times...


To disable improper automatic brightness control, uncheck this:

To control brightness manually from 0% to 100% , install xbacklight

$ sudo apt-get install xbacklight

Don't know how to overwrite functional keys for brightness, so I made two new shortcuts for brightness control, with commands:

$ xbacklight -inc 5
$ xbacklight -dec 5

For non 60 fps videos, mplayer works pretty well with this config:

$ cat ~/.mplayer/config
# Write your default config options here!

vo=gl_nosw
af=equalizer=0:-1:-2:-3:-4:-4:-3:-2:-1:0
cache=8192
cache-min=4
nosub=1
framedrop=1

Custom date time format on MATE panel
