Hi,

Well I am new to Linux (As well as to forum), so sorry if this is a stupid question.

Ok So I have ASUS M2N SE MX Plus Motherboard with AMD Athlon,4 Gig of RAM and a 500 Gig HDD.

I installed Ubuntu 11.04 on it. Everything works fine except one problem. When it initially boot (some command line stuff) it goes out of frequency and my monitor is blank saying out of frequency (i.e i can only see something after log in comes).I am using Samsung SyncMaster 793s monitor. I think the problem is with refresh rate.

It will be highly appreciated if someone can help me fixing this problem. Thank You.

This is a output of xorg.conf
