graphics

I recently switched from Vista to Ubuntu 12.10 on my HP laptop and I've been having issues with my graphics. Everything is fine till I watch a video/play a game or (sometimes) when I visit the software centre. At that point large portions of the screen start flashing and everything gets rather slow. I'm looking for a way to remedy this.

For reference I'm using Firefox and I'm unsure what my video card is because it's listed as unknown when I check my system settings.

How will people upgrade from 12.10 to 14.04 after 13.04 is EOL?

Looking at https://wiki.ubuntu.com/Releases 13.04 will reach EOL in January 2014, while 12.10 will reach EOL in April 2014, therefore if a 12.10 user hasn't upgraded to 13.04 and subsequently to 13.10, there will be a 3 month period where a 12.10 user has a supported version of Ubuntu, but will be… >>> More
