[ltp] How to tell XFree86 4 to ignore fixed LCD timings?

[Tino Keitel]

Hi folks,

1. I wonder if there is a magic option in XFree86 4.1.0 to get the X server 
to use the timings of the modelines given in the XFree86Config-4 file. At 
least my trident_drv.so ignores them and uses some fixed values that are 
hardcoded into the driver (an arry called "LCD" in trident_driver.c). This is 
very annoying since I also use a CRT. It only uses the timings of the 
modeline if it detects that the LCD of my TP is deactivated. Unfortunately it 
even detects an active LCD if it _is deactivated_ with Fn+F7.

I modified some source files and built an own trident_drv.so that ignores an 
active LCD. This works for me but I think there must be more "official" 
solution. I searched the docs but found nothing. Any hints?


2. Are there any positive or negative side effects if I use a refresh rate of 
40 Hz on my LCD (I think of energy saving because of a lower pixel clock)? It 
seems to work well.
