| Subject: i915: Quirk no_lvds on Gigabyte GA-D525TUD ITX motherboard |
| |
| From: Calvin Walton <calvin.walton@kepstin.ca> |
| |
| commit a51d4ed01e5bb39d2cf36a12f9976ab08872c192 upstream. |
| |
| This board is incorrectly detected as having an LVDS connector, |
| resulting in the VGA output (the only available output on the board) |
| showing the console only in the top-left 1024x768 pixels, and an extra |
| LVDS connector appearing in X. |
| |
| It's a desktop Mini-ITX board using an Atom D525 CPU with an NM10 |
| chipset. |
| |
| I've had this board for about a year, but this is the first time I |
| noticed the issue because I've been running it headless for most of its |
| life. |
