Input: i8042 - add Lenovo XiaoXin Air 12 to i8042 nomux list

2020-07-22T07:10:53+00:00

commit 17d51429da722cd8fc77a365a112f008abf4f8b3 upstream. This fixes two finger trackpad scroll on the Lenovo XiaoXin Air 12. Without nomux, the trackpad behaves as if only one finger is present and moves the cursor when trying to scroll.

Input: i8042 - add ThinkPad S230u to i8042 reset list

2020-06-03T06:16:39+00:00

[ Upstream commit 2712c91a54a1058d55c284152b4d93c979b67be6 ] On the Lenovo ThinkPad Twist S230u (3347-4HU) with BIOS version "GDETC1WW (1.81 ) 06/27/2019", the keyboard, Synaptics TouchPad, and TrackPoint either do not function or stop functioning a few minutes after boot. This problem has been noted before, perhaps only occurring with BIOS 1.57 and later.[1][2][3][4][5] Odds of a BIOS fix appear to be low: 1.57 was released over 6 years ago and although the [BIOS changelog] notes "Fixed an issue of UEFI touchpad/trackpoint/keyboard/touchscreen" in 1.58, it appears to be insufficient. Setting i8042.reset=1 or adding 33474HU to the reset list avoids the issue on my system from either warm or cold boot.

Input: evdev - call input_flush_device() on release(), not flush()

2020-06-03T06:16:38+00:00

[ Upstream commit 09264098ff153f60866039d60b31d39b66f55a31 ] input_flush_device() should only be called once the struct file is being released and no open descriptors remain, but evdev_flush() was calling it whenever a file descriptor was closed. This caused uploaded force-feedback effects to be erased when a process did a dup()/close() on the event FD, called system(), etc. Call input_flush_device() from evdev_release() instead.

Input: i8042 - add Acer Aspire 5738z to nomux list

2020-04-24T05:58:59+00:00

commit ebc68cedec4aead47d8d11623d013cca9bf8e825 upstream. The Acer Aspire 5738z has a button to disable (and re-enable) the touchpad next to the touchpad. When this button is pressed a LED underneath indicates that the touchpad is disabled (and an event is send to userspace and GNOME shows its touchpad enabled / disable OSD thingie). So far so good, but after re-enabling the touchpad it no longer works. The laptop does not have an external ps2 port, so mux mode is not needed and disabling mux mode fixes the touchpad no longer working after toggling it off and back on again, so lets add this laptop model to the nomux list.
