Hello everyone! I have only just installed Linux Mint 14 (MATE) as of about an hour ago. I did all the initial setup things as suggested on various posts here and Youtube and whatnot. So then I went to set up my dual monitors! I am aware of the limitation on "legacy" cards. Here are my specs:
Machine: HP Pavilion dv7
Card: ATI Radeon HD Mobility 4xxxx/5xxx (dual-head) <---- Has the ability to be a dedicated GPU and integrated w/ shared memory (presumably while on battery)
Left: HPx20 LED VGA
Right: Sony BRAVIA 32" HDTV (720p) w/ HDMI port hookup.
I have searched Google and these forums fruitlessly for a tip on how to set these up using these "open source" drivers. I attempted the fix listed in the release notes (in which one installs something called a "PPA" to revert back to an older version of another thing called "Xorg.") which caused all my monitors to go black. I had to re-install Mint.
I also had the same problem on a Mageia 2 distro I was using.
I am at a loss. Any help is appreciated. I've been using Linux for literally 2 days now and it's getting frustrating. I deleted my Windows partition and don't have the means to get it back. I don't have any recovery methods for it, so this machine is stuck with Linux. It's really neat, and I'd love to use it better, but this is so frustrating.
EDIT: It may also be helpful to point out that I currently have both displays plugged in. Only the HP VGA monitor registers. The TV stays black and doens't even show up in the "Monitors" setup dialogue.
