Hi all!!

I have a nVidia GeForce FX5900 with XFree 4.3.0 with latest drivers, and whenever i do a glxgears, or play a 3D game, my screen shakes horizontali, not very hard, but noticeable, specially on the edges of the screen. I tryed to change refreshing rate of the monitor and lower the resolution (current i'm on 1280x1024).

I also tryed to install previous drivers (53.28) with the same result.

I checked XFree log with that results:

(WW) NVIDIA(0): The user specified HorizSync "30.000-95.000" has been adjusted
(WW) NVIDIA(0): to "30.000-69.000" (the intersection with EDID-specified
(WW) NVIDIA(0): HorizSync "30.000-69.000")
(WW) NVIDIA(0): Not using mode "1400x1050" (width 1400 is larger than
(WW) NVIDIA(0): EDID-specified maximum 1280)
(WW) NVIDIA(0): Not using mode "700x525" (height 1050 is larger than
(WW) NVIDIA(0): EDID-specified maximum 1024)
(WW) NVIDIA(0): Not using mode "1152x768":
(WW) NVIDIA(0): horizontal sync start (1178) not a multiple of 8
(WW) NVIDIA(0): Not using mode "576x384":
(WW) NVIDIA(0): horizontal sync start (589) not a multiple of 8
(WW) NVIDIA(0): Not using mode "360x200":
(WW) NVIDIA(0): horizontal sync start (378) not a multiple of 8

I tryed to use Option "IgnoreEDID" "1" and Option "UseEdidFreqs" "1", and neither of both helped.
My screen is an ADI Microscan 17"

Please, i need some help. as this is driving me crazy, this is my first nvidia card after a whole life of ATi (yes, yes, i've seen the light!)

Thanks in advance
