ViewSonic VX2025wm EDID sync polarity fix quirk	none

Description Elvis Pranskevichus 2007-02-10 16:03:59 UTC

I have the following configuration:
- Intel 965G based mobo
- ViewSonic VX2025 wide screen monitor with native resolution of 1680x1050
- X.org version 7.1
- latest xf86-video-intel driver from git:modesetting branch

It seems that the monitor fails to correctly report the sync polarity for its native 1680x1050@60 mode and it results in a distorted mode being set. I posted my problem description to the xorg mailing list and got a hint that it is indeed the polarity misdetection. 

I managed to fix the problem by adding the flipping quirk to i830_edid_modes.c.
