KDE/Kubuntu Gnome apps will not accept the correct passwortd

I installed Gparted and the login sudo screen will not accept the correct password - it is actually gksu/sudo problem. To solve it, in terminal:

gksu-properties
Try that, set it to "sudo" and "enable"

Install Sopcast on Ubuntu 10.04.02 if you run VLC 1.1.x

I run Ubuntu 10.04 on my laptop, due to some hardware incompatibilities of 10.10 with my hardware, but I use the newest versions of vlc. So, I had to add some extra commands to run Sopcast on my laptop.
First, the PPA

sudo add-apt-repository ppa:ferramroberto/sopcast
sudo apt-get update
sudo apt-get install sopcast-player


Then, the fix



sudo apt-get install unzip
cd && wget http://www.mattrudge.net/files/sopcast-player_vlc1.1x-fix.zip
unzip sopcast-player_vlc1.1x-fix.zip
sudo mv vlc.py /usr/share/sopcast-player/lib/
sudo mv VLCWidget.py /usr/share/sopcast-player/lib/


You might have to 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
