• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description amadeus.bit 2008-06-29 00:49:50 UTC]

I use a TwinView system with 2 lcd flatscreens. when I set the vertical syncronisation to a specifict value(here 75hz both) only the second screens runs properly. I dont know when this bug occured, but at the beginning it worked fine.

here my xorg.conf

Expected Results:  
both have the same frequenzy

sorry, forget the actual error message:

> (WW) NVIDIA(0): Unable to parse range in VertRefresh string "75"; ignoring

The warning message asks for a range, not a single value, so maybe providing a range helps.


Not sure if this is abug and if it is, we cannot do anything wrt. Nvidia's blob or is this part of the code open?

uh, assign...

[Comment 4 Tony Vroon (RETIRED) 2008-06-29 17:03:40 UTC]

75 isn't a range.
74.9 to 75.1 is. This is reported against the wrong package (the error message is from x11-drivers/nvidia-drivers). Please use nvnews.net forums in the future as this should be discussed with upstream.
