mame is really slow on my netbook when it was running windows 7 mame ran at full speed, but after I installed lubuntu it runs at about 30%. I think I have all the right drivers how can i make it go full speed again?

Here's the results of lspci -k | grep -EA2 'VGA|3D'

00:02.0 VGA compatible controller: Intel Corporation Atom Processor D2xxx/N2xxx Integrated Graphics Controller (rev 0b)
Subsystem: Acer Incorporated [ALI] Device 0624
Kernel driver in use: gma500

As you don't say, I guess your netbook has Intel graphics.

You will never get the speeds you got in Windows on Ubuntu with those graphics, the support from Intel is just not there for the drivers.

You say

but after I installed lubuntu it runs at about 30%.

You would get better performance with xubuntu as lubuntu is very striped down and not meant or gaming at all, you could potentially see a good increase in performance with xubuntu, only use lubuntu if you must on your hardware.

Thanks to @pilot6 for pointing out, newer kernel has good drivers for newer Intel chips with mesa but the older GMA chips have poor support, as you never mentioned the GPU you have, I don't know what chip you have, but as you are using lubuntu I am just guessing your chip is older.

I'm running Lubuntu 15.10 on a DELL Dimension 3000 and have Intel Graphics Drivers ONLY with basic hardware. I've been able to MAME work full speed from a slow running state doing the following below:

mame -mt -sdlvideofps -video soft -rs

Here's the output I got from the last ROM I tested: [Workaround]

3.48s, 22 F, avrg game: 6.32 FPS 158.22 ms/f, avrg video: 6.52 FPS 153.31 ms/f, last video: inf FPS 139.97 ms/f Average speed: 100.00% (15 seconds)

Try some of these options listed here to tweak your system's MAME on Terminal to run optimized.

http://manpages.ubuntu.com/manpages/precise/man1/mame.1.html

Then use the following default settings inside this file to permanently setup your mame.ini to run the settings you customized in Terminal:

sudo gunzip /usr/share/doc/mame/examples/default.mame.ini.gz
