Linux Mint won't shutdown after installing Trinity

Hello. I'm a regular user and after installing Trinity with Raring packages in Mint 15, system won't shutdown/restart but hangs at plymouth. Is there a workaround for this because I have to use REISUO to shutdown and REI part doesn't work because for some reason it's disabled. Please help. (I've installed and reinstalled several times and issue occurs only with trinity desktop. I usually install only kdebase-trinity with kmix-trinity and compiz-trinity packages. Thanks.
