Re: Fwd: ThinkPad L540: suspend not working (deep / S3 / standby, regression Linux 4.19 -> 6.1)

[Hans de Goede]

Hi All,

This looks like something for Benjamin Tissoires (who will
be available to look at this in 2 weeks or so) to look at.

Adding Benjamin to the Cc.

In the mean time passing psmouse.synaptics_intertouch=0 on the
kernel commandline should restore the old 4.19 kernel behavior
of simply using the touchpad in ps/2 mode.

Regards,

Hans
