Not sure what is going on there, but you are running X as root. Running applications on Linux as root is discouraged and often not supported. Try to run X as a user.

Hai Emerson,

Thanks for your response.Every package I have installed is within root only.. Doesnt startx work if it is run with root priviliges..

I do not know, I've never ran X as root, this is the second most stupidest thing to do (first is using a computer as root). You install apps as root, yes, but then you use these apps as a user. This is the UNIX way. There is no point doing LFS and ignoring [security] basics.

@Aniz,
It might be better to have a moderator move this thread to the 'Linux From Scratch' formum. Building X is a non-trival task and you will find that someone familar with BLFS to be in a better position to answer your questions about what is wrong with your build. It has been several years since I did a BLFS X build and I'm not familar with the current requirements.

To ask that the thread be moved, just click on the 'report post' button at the bottom of your initial post. That brings up a template where you can type in the request and the reason.

Good luck. Once you get it built and running you'll find it to have been a road worthwhile taking.

I believe I've run X11 as root. It's run as part of an embedded system by an /etc/init.d script. I needed it to run the X server so that the UI program we have would be able to load; it can't work via the framebuffer. That all is done via start up scripts so that the product boots directly into our UI.
