I did a bunch of reading this morning on the newest Nvidia Driver. NVIDIA-Linux-x86-173.14.05.pkg1.run
I installed the driver using this wiki http://wiki.linuxmce.org/index.php/Display_Drivers
A link to the NVIDIA read me file http://us.download.nvidia.com/XFree86/Linux-x86/173.14.05/README/chapter-03.html
I read all through the custom settings for the install as I wanted to use 1080I on 710RC2 for my sony 57 rptv. I thought I was in for a painful day of modifying the xorg.conf file. Well! two things the newest driver includes an easy nvidia-xconfig editor. The other major thing I found out is that if you are using the "TV out" on your video card with Component, Compsite etc... adding mode lines to the config will not help you as the driver bypasses them and used the --tv-Standard= command.
So that being said from LMCE I hit ctrl-alt-f2 to get to the command prompt goto to the root and issued a telinit 1 command (note if you are not familiar as i was not this shuts everything down including X and then pops up with a dcerouter_765743 or the like. I had to re login to dcerouter and issue another sudo -s to get back to root.
Then I loaded man nvidia-xconfig. there it will give you all the command line options for anything you want to add to the xorg.conf file. My Tv out was already being used so I did not have to enable it. and I already have more than enough overscan to deal with so I left this disabled. so my command line was
nvidia-xconfig --tv-standard=HD1080i enter
It will save your original copy and write a new xorg.conf fole and tell X to start using the new one.
I then started X to check and it was noticable right away over 720P. As i stated my TV has never looked good at 720. I then went back to the command prompt and issued a reboot command. LMCE loaded perfectly, did not start the wizard and it looks GREAT. I am noticing NO slow downs in the gui any where and all fuzzy text on the on screen orbiters is clear again. I even started up the Sony Service menu in my TV to make sure that it was seeing 1080I. This TV does not tell me what resolution I am currently receiving I have to check it in the service menu.
hope this helps. I am learning as I go - totally new to Linux as well. So I will help where I can. I read alot. LOL.
This is how I did it but I had a laptop right beside me the whole time reading the Nvidia read me file from the same place I downloaded the file. If anyone has any suggestion for the overscan on the KDE desktop they would be welcome as I cannot figure that out for the life of me. The overlay in LMCE looks great and my only issue with the overlay is that I cannot setup MYTH from within LMCE because I cannot access the yes no continue buttons at the bottom of the screen. Thanks in Advance.
