Just like Fujitsu CELSIUS H730, the H760 also has an Elantech touchpad with the same quirks. Without this patch, the touchpad is useless out-of-the-box as the mouse pointer won't move. This patch makes the driver aware of both the crc_enabled=1 requirement and the middle button, making the touchpad fully functional out-of-the-box. Signed-off-by: Matti Kurkela <Matti.Kurkela@iki.fi> --- This patch will also apply without changes to older kernel versions: I made this originally on 4.4.19 and am currently using it on my work laptop with 4.4.22. Backporting to any version that includes commit f386474e12a560e005ec7899e78f51f6bdc3cf41 should be trivial. -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
