[SOLVED] touchpad not work on F22

Hi ,

The touchpad don't work me on F22.

How can I debug this issue ?

Thanks, see you.

Which model laptop?

You can use xinput to discover how you touchpad is detected/handled:

xinput list

Then use the device ID reported to find out more info with

xinput list-props <device-id>

The reported info might help others advise further. Chipset details can be useful.

It could be worth checking for kernel messages relating to the input devices eg

dmesg|grep i8042

Hi ferrari ,

The model is a acer Aspire ES1-111M-C5PH.

More ideas ?

Thanks, see you.

The touchpad is not recognised according to the xinput output. Make sure that is is enabled first. I've seen a couple of web pages (for a similar model) that suggests Fn+F7 might do that. The other suggestion that I have read is to check the BIOS setting for the touchpad - it might be possible to configure 'basic' mode from there and get it working. Failing that, it might be necessary to raise a bug report.

FWIW, one such page describing touchpad issues with similar Acer models...

It might be worth reviewing the answers given here too

Hi I had similar problems with my Acer Aspire V3. Here's what I figured out: Modern synaptics touchpads provide two modes of operation: one via i2c and one via ps2. There's no proper driver yet for the i2c mode, but the ps2 mode works just fine. The problem however is, that once the touchpad was detected as an i2c device it shuts down the ps2 mode until the next reboot. The solution is to blacklist the i2c-hid module so the device isn't initialized in i2c mode and the ps2 mode remains active. On my machine I had to additionally set i8042.nopnp=1 on the kernel cmdline. Else the touchpad didn't work at all in ps2 mode. However you might not need this, or you might need i8042.nomux=1. Just try it out.

It may or may not be applicable. YMMV.
