Re: Not getting correct resolution
You may want to try adding this "cheat code" to the end of the GRUB boot line at the boot menu prompt before pressing enter and see if that gives you the correct resolution with your display:
If you decide install Mepis to your hard drive, I'd just install the proprietary Nvidia driver. That way, you'll have the Nvidia Control panel with more features.
The easiest way to do that is by using the sgfxi script. See this page about it:http://www.mepis.org/docs/en/index.php? ... 28sgfxi.29
Basically, you just install the script, then follow the instructions on that page to run it (press CTRL+ALT+F1 to exit to a login prompt, then login in using user name root and type sgfxi and use the defaults). That script will download and install the latest stable driver for you by default (295.20 right this minute). Then, after it runs, you'll see a choice to exit (which shuts down mepis) or start desktop (I'd try that first).
I don't know if you could use it from a Live DVD with aufs or not. If you try it, make sure to use the Start Desktop versus Exit option after the sgfxi script finishes installing the driver (otherwise, you'll reboot and be right back where you were to begin with).
Just note that sometimes you may need to run the script more than once. For example, when I upgraded from Nvidia 285.05.09 to 290.10, I had to run the sgfxi script again. More recently, I upgraded from 290.10 to 295.20 and it only took one run, with the desktop starting fine using the newer driver without a reboot when using the Start Desktop option after running sgfxi. That's just a "quirk" with the way it works (sometimes needs running more than once to remove the old driver and installing a newer one).
If you install Mepis 11 to a hard drive, I don't think you'd have any issues once you install the Nvidia proprietary driver using the sgfxi script.
But, from a Live DVD, I'd try using the cheat code nvidia.modeset=0 (just add it to the end of the grub boot line) and see if that helps anything. If not, see if you can download and run the sgfxi script from a Live session after choosing the aufs option (and again, I don't know if that would work from a Live session or not).
