From: Peter Osterlund Here is a fix for synaptics touchpads with "multi buttons". The patch comes from Hartwig Felger, who wrote the original multi button support patch (p00003_synaptics-multi-button.patch). The same bug fix has been included in the XFree86 driver for a few weeks, and seems to work fine. (That part of the X driver is only used for 2.4 kernels.) drivers/input/mouse/synaptics.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletion(-) diff -puN drivers/input/mouse/synaptics.c~syn-multi-btn-fix drivers/input/mouse/synaptics.c --- 25/drivers/input/mouse/synaptics.c~syn-multi-btn-fix 2003-08-14 11:59:32.000000000 -0700 +++ 25-akpm/drivers/input/mouse/synaptics.c 2003-08-14 11:59:32.000000000 -0700 @@ -433,7 +433,8 @@ static void synaptics_parse_hw_state(uns if (hw->right) hw->down = !hw->down; } - if (buf[3] == 0xC2 && SYN_CAP_MULTI_BUTTON_NO(priv->ext_cap)) { + if (SYN_CAP_MULTI_BUTTON_NO(priv->ext_cap) && + ((buf[3] & 2) ? !hw->right : hw->right)) { switch (SYN_CAP_MULTI_BUTTON_NO(priv->ext_cap) & ~0x01) { default: ; /* we did comment while initialising... */ _
