Hi there, Im using GeForce FX5200 dual DVI graphics adapter connected with two Samsung 204b monitors. At the moment I'm using binary nvidia drivers and everything works fine but I'm forced to switch to nouveau. Unfortunately there are problems. It seems that nouveau.ko wrongly detects the PixelClock of my monitors. More precisely, after loading of nouveu.ko the screen starts to blink. According to my experience the problem is too hight PixelClock. Moreover, in the /var/log/Xorg.0.log you can find the line:
NOUVEAU(0): Ranges: V min: 56 V max: 75 Hz, H min: 30 H max: 81 kHz, PixClock max 175 MHz which is false. The maximum PixClk for Sumsung 204b is 162MHz. I was trying to play with the video= kernel parameter but there is no way to force the PixClk. I was also trying to edit the suitable ModeLine in the drivers/gpu/drm/drm_edid_modes.h but I thing nouveau.ko ignores it. So my question is what to change (in the kernel source) to override the detection and force MaxPixelClock to 162MHz just to make sure that the problem is related to PixelClock. To build the kernel I used the kernel tree downloaded from nouveau about one week ago. Thanks in advance for any help. _______________________________________________ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau
