The no. But if Xorg.0.log tells me (in the bad case): (II) NVIDIA(0): Validating Mode 1920x1080: (II) NVIDIA(0): 1920 x 1080 @ 50 Hz (II) NVIDIA(0): For use as DFP backend.

(II) NVIDIA(0): Setting mode 1920x1080_50 and it uses a 60Hz modeline though this is clearly a Xserver bug for me. Do you know if it has been reported to Nvidia? I think the X.org people would not look at it, since you use the proprietary driver.

I dont't know if especially this problem has been reported to nVidia. There are heaps of error reports of that kind reported to nVidia that all sound quite similar. - Thomas ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

This is clearly a bug for me because the Modes 1920x1080_50 setting is ignored and on top of that Xorg.0.log lies about this. After specifying the modeline directly in xorg.conf (the workaround) the tool and Xorg.0.log reported 50Hz. And live ticker scrolled smoothly without any jumping. For me this is evidence enough the tool reported the right thing in both cases. cheers Thomas ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
