Forcing 60hz on a laptop display.
 

Hi there basically I have a friends laptop here that he requested me to install redhat 9 upon. Now that is all fine until it comes to setting up X properly. The screen shimmers a lot which either means it is refreshing to low or to high...?

All im wondering is when im in the XF86CONFIG file what entry would I need to put in under screens to force it to use the 60hz refresh as is the norm for an lcd . It is using the generic laptop 1024*786 monitor setting as it doesnt have support for the laptop screen as it is new ... that and I cant for the life of me figure out what make the screen is.

The laptop is a Packard Bell Easynote.

Don't know if you have a PB Easynote e3174, if so take a look here:

For general PB notebooks take a look here:

Thx for the link but it didnt help me. The easynote I have here is newer than that one by a fair few months afaik. I assume if I get the correct modeline entry then it will work ok? Just I dont know where or how to construct the modeline entry as I dont have a model of the screen they use on these bloody laptops!

There is an on-line mode generator:

Maybe this will help.
