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 --- 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. --- linux-4.8/drivers/input/mouse/elantech.c.orig 2016-10-03 02:24:33.000000000 +0300 +++ linux-4.8/drivers/input/mouse/elantech.c 2016-10-03 20:19:17.175141070 +0300 @@ -1159,6 +1159,13 @@ static const struct dmi_system_id elante DMI_MATCH(DMI_PRODUCT_NAME, "CELSIUS H730"), }, }, + { + /* Fujitsu H760 also has a middle button */ + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "FUJITSU"), + DMI_MATCH(DMI_PRODUCT_NAME, "CELSIUS H760"), + }, + }, #endif { } }; @@ -1503,6 +1510,13 @@ static const struct dmi_system_id elante }, }, { + /* Fujitsu H760 does not work with crc_enabled == 0 */ + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "FUJITSU"), + DMI_MATCH(DMI_PRODUCT_NAME, "CELSIUS H760"), + }, + }, + { /* Fujitsu LIFEBOOK E554 does not work with crc_enabled == 0 */ .matches = { DMI_MATCH(DMI_SYS_VENDOR, "FUJITSU"),
