Ok, I installed debian 7.8 and I could use graphics, no best resolution but I guess after install backports or linux-firmware-nonfree I will have different resolutions.
I tested omv and it worked perfect over the debian installation
Tomorrow I wil try a fresh install because I was getting crazy with so many systems, grub, etc. It's a mesh. And you have to add the problem with the nic, so yes, I have too many problems to make a simple install lol.
After all I think there is hope for my config.
