I am trying to configure my X window environment and currently facing a problem in setting up the hsync and vsync of my laptop monitor.
Is there any tool that can detect these rates?
Btw, my screen in 12.1" WXGA Acer CrystalBrite LCD
For those values, it is usually best to see what the manufacturer lists - check manual or website. I don't specify those values in the xorg.conf of my laptops and they work fine.
You can try this command to get some good screen info though:
On my box (Fedora) it is in the xorg-x11-utils package.
Also, you can try to let X determine your best settings. Try these steps:
1. (re-)boot into non-Graphical runlevel (init 3)
2. log in as root
4. test it with
X -config /root/xorg.conf.new
(or whatever the generated xorg conf file is called)
5. press Ctrl+Alt+Backspace to get out of the X test window
and see if that works for you.
