Hdmi no video or sound.

Hey Guys,
i have used Linux in the past. Ubuntu and mint mostley. I just recently tried to dual boot my Win7 machine with Mint 14. This turned out to be a nightmare as, for whatever reason, now my Windows won't boot. No problem. I can still get to all my files on that partition and run them in Mint. Well, I have had one problem after another trying to get alll my devices working in Mint 14. My biggest issue is dual screens. I am using an AMD/ATI radeon 6450 graphics card and it wont detect my panasonic 50 inch at all with HDMI. It shows 2 monitors when I have the HDMI cable hooked up, but not the correct one. I have tried configuring my Nvidia-Xserver settings, but its givinng me a driver error. Everytme I go to use the terminal it tells me permission denied. This is very frustrating and I don't want to give up on Linux. If anybody can help me with this I would greatly appreciate it.
Thanks in advance.

I have tried configuring my Nvidia-Xserver settings, but its giving me a driver error.

I'm quite a n00b myself but that doesn't sound good. If you're getting a genuine 'driver error' message (rather than some kind of permissions message) I'd look into re-installing the drivers. It may or may not solve the HDMI issue but at least it'll clear up one potential problem area.

Nvidia-Xserver works with nvidia hardware. You have amd/ati.


What video driver is installed:

Code: Select all

$ inxi -Gx

You can try the binary driver:

Code: Select all

$ sudo apt-get install fglrx-amdcccle fglrx

Reboot. You should have the amd control center installed. HDMI should work. Test with the first command; it should say fglrx now.
