Lenovo touchpad not working on CentOS 7.5

Post by grittt » 2018/09/29 15:10:29

Hi, the touchpad on my Lenovo ideapad 320 has never worked since I installed CentOS (it worked before, with Win 7). The mouse works fine, but I'd prefer to have the touchpad. The touchpad system settings look fine. From what I've read, the cause might be a bug in the kernel. Any suggestions for how to verify if that's the case, and how to fix it? Cheers.

Is the xorg-x11-drv-evdev package installed?

Package xorg-x11-drv-evdev-2.10.5-2.1.el7.x86_64 already installed and latest version
Nothing to do

Yes, it is - as above.

Does lsusb or lsusb -v|more show anything useful? Maybe you're missing a module/driver?

Also check in the log files /var/log/messages and /var/log/Xorg.0.log for more information. Perhaps there are errors in the messages file? Or more specific information about what it thinks your touchpad is and why it's not working in the Xorg log file.

I get the following output from lsusb
$ lsusb
Bus 001 Device 004: ID 13d3:5a02 IMC Networks
Bus 001 Device 003: ID 0bda:0821 Realtek Semiconductor Corp.
Bus 001 Device 002: ID 0438:7900 Advanced Micro Devices, Inc.

Bus 002 Device 002: ID 248a:8367 Maxxter
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Which one is the touchpad? The lsusb -v|more is very long - what should I be looking for exactly?
Thanks

That's not the entire Xorg.0.log, it's only the first screenful (you can tell by the " "Xorg.0.log" [readonly] 1088L, 79596C" at the end). Do this instead: yum install cpaste then, once it's isntalled, cpate /var/log/Xorg.0.log then post the link it provides here. The paste on paste.centos.org will expire in 24 hours so make sure you post the link here ASAP to give us all a chance to read it before it expires.

I'm going through Xorg.0.log, and will post the resolution here when I find it.
