when run from terminal:

The trick is to remove (or just move, just in case) the ~/.config/chromium folder and let it recreate itself when chromium-browser starts

also maybe:

sudo chown -R username:usergroup -R ~/.config/chromium

#!/bin/bash

sudo mkdir /home/ubuntu/drive_p

# unmount previously-mounted drive

sudo umount /home/ubuntu/drive_p

sudo smbmount "//192.168.1.11/wdtv_data" /home/ubuntu/drive_p -o username=default,password=default,uid=999,gid=999

iPad won't charge

Since you know the charger itself works, reboot your iPad and try to charge again.

Hold both the power and home buttons at the same time for at least 10 seconds (keep holding past the swipe to shut down if it appears) until the Apple logo appears then let go and your iPad will restart.

Installing Sopcast

http://www.webupd8.org/2010/05/install-linux-sopcast-player-040-in.html

1. You must download libstdc++ manually because this package is not included in the Ubuntu repositories. Don't worry, you can use these .deb files:

• 32-bit
• 64-bit

2. Add the SopCast Player PPA and install SopCast Player:

sudo add-apt-repository ppa:ferramroberto/extra && sudo apt-get update
sudo apt-get install sopcast-player sp-auth

And that's it, now go to Applications > Sound & Video > SopCast Player.

Ubuntu 11 classic menu

How to change back to classic menu. The new menu is horrible:

http://ricochen.wordpress.com/2011/05/13/how-to-swith-back-to-classic-menu-in-ubuntu-11-04/

1) Click on the Ubuntu icon on the top left corner, type “login screen” and click on the “Login Screen” application

2) Click unlock, enter password and the window should become the following, choose “Ubuntu Classic” from the dropdown menu, click Close then REBOOT.

If Live CD / USB boot is used, then it will prompt username/pw after reboot. The default username/pw is 'ubuntu' and blank password

sudo apt-get install smbfs

in /etc/fstab :
sudo gedit /etc/fstab

smbmount //servername/sharename /mountdirectory -o username=mywindowsusername,password=mywindowspassword

if un/pw not needed, use 'defaults'

smbmount //192.168.1.11/WDTV_DATA /wdtv -o username=defaults,password=defaults


===
Note, apparently the above does not work with live/usb boot? Manually:

sudo mkdir /media/wdtv
sudo smbmount //192.168.1.11/WDTV_DATA /media/wdtv -o username=defaults,password=defaults

ls /media/wdtv
df -l
fdisk -l

Shell Script:

#!/bin/bash
sudo mkdir /media/wdtv
sudo smbmount //192.168.1.11/WDTV_DATA /media/wdtv -o username=defaults,password=defaults
