Touchpad unresponsible after low power (mageia 6)

Hello,

I have got this problem: my laptop works well wit a fresh installation, but it happens that after in enters low power mode the touchpad just becames unusable. You can't move the mouse anywhere an it clicks randomly all around the desktop. It remains quiet if you don't touch it.

In this situation the only option is to reboot or to connect a regular usb mouse.

This happens whenever I left the laptop five minutes and it shuts down the screen, it's doesn't need to go to sleep or anything although same happens when going to sleep mode.

This is in mageia 6 with kde and everything up to date. The only strange thing I noticed is that into kde options it says that there isn't any touchpad installed just a regular mouse. If check in drakconf it also shows that the mouse is "ImExPS/2 Generic Explorer Mouse" and is using module "mouse0". I expected it be the synaptics driver but I might be wrong. Anyhow I can paste with three fingers and scroll with two fingers, and all that, the touchpad seems to work well.

Any ideas? Thanks for the help.

check if this is installed.

I know on mine and someone elses this missing meant that the mouse was only performing like a basic mouse.

x11-driver-input-synaptics

it did not auto install on mageia 6 for me.

are the settings under touchpad configurable?
i found they were not without the above package

You are right, the package wasn't installed. But still I can't configure the touchpad from KDE settings it just says that "No touchpad found". Just like before.

By the way the problem persists, I can trigger it easily just closing laptop lid and the opening again. I guess I force somehow to use the synaptics driver.

run lsusb and detect what the mouse realty is.
what you see in kde might just be the emulation its picked.

for example like keyboards work 90% with any selected keyboard emulation.

Well, lsusb says that I don't have a tuchpad or mouse of any kind.

Code: Select all
[root@charcoal ~]# lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 090c:037c Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.) 300k Pixel Camera
Bus 001 Device 003: ID 8087:0a2a Intel Corp.
Bus 001 Device 002: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller

[root@charcoal ~]#


Checked connecting my external mouse and a mouse device becomes visible. Trackpad was working while I ran the command.

Any idea, I have also tried with lspci and and lsmod and with the second one got this:

Code: Select all
[root@charcoal ~]# lsmod|grep mouse
psmouse               139264  0
[root@charcoal ~]#


Searching around the webs seems indeed that this is the trackpad driver I'm using. Now the question is: There may be a bug with this particular driver? Can I use synaptics instead? I think I read on the brand webpage that it was possible to use synaptics driver but i need to check.

Anyhow psmouse is a crap, not only because of my problem but also because I cannot tune any parameter (since kde doesn't recognize it as a trackpad) like acceleration, sensibility double click speed, all that.

EDIT:
Ok, I will definitely open a bug for this. Definitely there is something wrong here. I got a dirty workaround simply rmmod psmouse and modprobe psmouse.

i was about to post id discovered a similar problem on my logitech universal recievers at the weekend, where they kept going to sleep, realy anoying
as everytime id stop typing or started moving the mouse it would be stuck for a while.

not sure why this has suddenly become a problem, some update maybe. anyway disabling the usb power/control and power/autosuspend worked on that.

ive just read my origional stuff on my trackpad on my laptop and your right, its not a usb devices as such.

try
cat /proc/bus/input/devices

on mine this was

I: Bus=0011 Vendor=0002 Product=000e Version=0000
N: Name="ETPS/2 Elantech Touchpad"
P: Phys=isa0060/serio4/input0
S: Sysfs=/devices/platform/i8042/serio4/input/input1
U: Uniq=
H: Handlers=mouse0 event1
B: PROP=5
B: EV=b
B: KEY=e420 10000 0 0 0 0
B: ABS=661800011000003

so now you have your vendor and your product codes.

once we know what yours is it may help dictate what the next steps are.

theres a load of old stuff here, thats largly irrelevant, today, but may hint you in the right direction
