How to enable graphics acceleration for SIS 771/671 on Zorin OS 8 lite (lubuntu 13.10)

Anyone knows how can I check/test my 2d acceleration? See if it's on/off and working correctly and as efficient as it should? I have SIS 771/671 on Zorin OS 8 Lite. I believe the resolution should be better (it's 1024x768 right now and it looks a bit stretched horizontaly I assume 1024x1800 could look fine) and I feel video could go more smoothly and also I see some horizontal lines on the screen when playing movies. So basically I think that the video driver is still not proper here. I found this instruction here at comment #230: sis drivers discussion I have a patch here : https://www.archlinux.org/packages/?name=xf86-video-sisimedia btw the patch is for 13.04 - will it also work or be needed for 13.10? Otherwise is there any other recommended lite distro on which SIS 771/671 could work fine and with acceleration ON?
