Chromium won't start in Lubuntu

when run from terminal:
ERROR:process_singleton_linux.cc(443)] readlink failed: Input/output error


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

sudo mkdir /home/ubuntu/drive_p

# unmount previously-mounted drive
sudo umount /home/ubuntu/drive_p

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

uid can be found using 'id' command.

Restore missing Task Panel / Task Bar in Ubuntu

Open Terminal (Alt-F2)
then type "gnome-terminal"
also, you can run "firefox"

Then run these commands:

gconftool-2 --shutdown
gconftool --recursive-unset /apps/panel
rm -rf ~/.gconf/apps/panel
pkill gnome-panel

The task panel should appear just after you execute the last line.

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


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:

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.

SoundBlaster Live and Ubuntu

In old Ubuntu versions asoundconf is used:

sudo asoundconf list
sudo asoundconf set-default-card Live
then Reboot

But now, simply select from System > Preference > Sound

Ubuntu 11 classic menu

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


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

Mount/map Windows share permanently


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 // /wdtv -o username=defaults,password=defaults

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

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

ls /media/wdtv
df -l
fdisk -l

Shell Script:
sudo mkdir /media/wdtv
sudo smbmount // /media/wdtv -o username=defaults,password=defaults
