From the description it seems that the LVDS can work well if the refresh rate is 50Hz. But when the refresh rate is 60, it can't work well. Right?
How do you change the refresh rate? In the boot phase or by using xrandr?
From the log it seems that the preferred mode is 1440x900*50 for the LVDS. In such case it will choose the 50HZ display mode.

Will you please also confirm whether this issue can be reproduced in UMS mode? (Adding the boot option of "i915.modeset=0").

Thanks.
