I'm on 12.04 precise with an AMD Radeon 6520G graphics card (using the open source driver which supports my card), and I am having problems with my display resolution stuck on 1024x768
To fix this, I'm trying to reinstall my drivers as recommended in these askubuntu posts one and two which instructs to reinstall xserver-xorg-video-ati but I noticed that I do not have that installed, instead xserver-xorg-video-ati-lts-quantal is installed although I am on precise.
So, what's the difference between these 2 packages and xserver-xorg-video-ati-lts-raring? Which one should I use in my context, for someone who wants to use the open source Radeon drivers on Ubuntu 12.04?
Very similarly, there's also the xserver-xorg-core package which is currently not installed and also has same name styling packages.
More searching led me to https://wiki.ubuntu.com/Kernel/LTSEnablementStack the LTS stack, which means that newer kernels and X stacks (stacks, being many X-related programs that are dependent on each other) are brought in from, but I'm unsure whether one is most appropriate for 12.04 especially in my system that uses the Radeon module.
