Description
For many years im using ubuntu (since nouveau becomes the default nvidia driver) and never have problem with the yuy2 scalemode mame option, so i think there's a regression with nouveau version in ubuntu 13.10.
I cant get video when open mame with "-video soft -sm yuy2" options using the nouveau driver. The game runs with sound, but in full black screen.
Using "-video soft -sm none" the game runs with video, the problem is with yuy2 scalemode.
Tested with Ubuntu 13.10 (kernels 3.11 and 3.12 from ubuntu repos.), mame .151 and .152, nouveau driver.
To reproduce (dont need any rom): execute the mame (mamedev.org) with the command line "./mame -video soft -sm yuy2" and mame will open totally in black screen. With the command "./mame -video soft -sm none" will open normally (in this case with a red bar warning about no roms).
