intel graphis not works properly
I did nothing i simply changed my distro to ubuntu 12.04 and everything works dine in ubuntu
even after providing a stable version why mint13 mate is not so compatible with my system
for the very first time feel fed-up with mint which is a favorite distribution of mint i used it for 6 years in series starting from mint felica till lisa distro of mint .
