resolution 640 X 480 only
 

hi everybody,
perviously iam using windows xp in my local machine and i shift to 32 bits rhel6 i have successfully installed in my local machine. when working with windows xp my CRT monitor supports graphics setting upto 1024 X 768 but after installing rhel6 it has only one resolution 640 X 480, its difficult to use linux for me. 2.6.32-71.el6.i686 this is my kernel of linux. so how i was able to use screen resolution 1024 X 768 in rhel6...? is there any way to handle this problem or i was not able to use high resolution. iam new to linux if somebody guide me right way i'll be greatful.

Post output of (from a terminal/konsole in RHEL6)
