Error:can't open display
I display card dirvers is non-open nvidia, and 3D accelarated program wrok right!
it says cant't open display
so the DISPLAY environment variable is not set !
somehow it is getting unset or over-ridden in your profile files
usually it must say
can't open display <followed by the string of the DISPLAY variable>
just execute these commands to check
# DISPLAY=:0.0 xlogo
this must set the display and also run it ! cannot get reset
