Hi,

a warning: It seems that "nvidia-settings" outputs a wrong refresh rate at least with Driver 195.30:

Screen is switched to 24p:

Code:

root@livroompc:/tmp# xrandr
Screen 0: minimum 320 x 175, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
   1920x1080      50.0     60.0     24.0*

However:

Code:

root@livroompc:/tmp# nvidia-settings -nt -q RefreshRate
50.00 Hz

Since the call to nvidia-settings is used by XBMC to detect the current refresh rate of the screen, this causes problems with the video sync methods.

Best Regards,
Olli

Shit.

You could rename nvidia-settings to something else as a workaround.

I'm seeing the same effect with 195.22.

However, on a diffferent box with Jaunty and 195.30, the problem doesn't occur.

Perhaps it's related to this particular chipset:

(II) Dec 25 23:09:16 NVIDIA(0): NVIDIA GPU GeForce 8200 (C77) at PCI:2:0:0 (GPU-0)

Hmmm ... I don't seem to be seeing this, I'm using that version driver

xrandr
Screen 0: minimum 320 x 175, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
1920x1080 50.0 60.0 24.0* 25.0 30.0

nvidia-settings -nt -q RefreshRate
23.97 Hz

I found the reason: When GPUScaling is activated (on this particular IGP?) -- which is on by default -- the actual frontend refresh rate is ignored.

Disabling GPU Scaling fixed this. There are various ways for doing this, I used

Code:

Options "FlatPanelProperties" "Scaling=Native"

in the xorg.conf "Device" section

Sorry for the misreport.

I wonder if it might be the case that randr reports the wrong refreshrate and nvidia-settings reports the right one, I've seen that happen a couple times.
