Subject: [PATCH 1/2] Synaptics rate switching
Date: Sat, 10 Jan 2004 03:45:13 -0500 [thread overview]
Message-ID: <200401100345.17211.dtor_core@ameritech.net> (raw)
In-Reply-To: <200401100344.03758.dtor_core@ameritech.net>
===================================================================
ChangeSet@1.1512, 2004-01-10 02:42:42-05:00, dtor_core@ameritech.net
Input: Allow switching between high and low reporting rate for Synaptics
touchpads in native mode. Synaptics support 2 report rates - 40
and 80 packets/sec; report rate must be set using Synaptics mode
set command. Rate is controlled by psmouse.rate parameter, values
greater or equal 80 will set 'high' rate. (psmouse.rate defaults
to 100)
Using low report rate should help slower systems or systems
spending too much time in SCI (ACPI).
