The documentation page needs to be rephrased - while some emulators only have a 32/64 bit version, RetroPie works on both x86 and x86_64.

@mitu Thanks for the help. I will try install opengl drivers and try launch game again. If the probled will be solved , i type about this

@mitu Yeah, I don't know. Maybe I'm missing dependencies.. Well thanks for helping anyway. It's appreciated.

It seems like the multiplier is locked. I think I was able to track down a reasonably priced 3.1 ghz core 2 to replace it with. Once I upgrade the graphics card in my main PC, I'll probably put the geforce 570 in there, too.

Thanks. I will check tonight. I think , I will just start from the beginning with Ubuntu anyway if that is more stable

Update. So this doesn't really work consistently (the changes I made...) but I'll leave it there for anyone wanting to see if they can fix it. It works some of the time for me but not everytime the system boots up...

The docs cover this scenario - take a look at https://github.com/RetroPie/RetroPie-Setup/wiki/Running-ROMs-from-a-USB-drive

@kaltinril I'm not currently working on this, but I found a trick that maybe you like to know: https://github.com/RetroPie/EmulationStation/blob/master/SYSTEMS.md#steam The problem I'm facing is that when I exit the game, the steam keeps running. There's no window, but its icon is on my Linux Mint Cinnamon systray and EmulationStation windows keeps hiden. If I close Steam (right click on that icon and exit) the EmulationStation goes back. Maybe a small hack to kill steam after exiting a game can be easy to do, but I'm not giving attention to this currently. Just sharing the trick on that link. :-)

The repository has been updated and I can now build in x86_64

@backstander awesome! Thanks again

@squiike Nothing will be deleted.

So I am going to say installing the SteamOS driver is probably a bad idea seems to have broken standard functionality. Specifically after disabling and removing the driver. Having to rekick now to get it back to normal.
