Lenovo IdeaPad-3-15IIL05 No touchpad

[stevef]

There are 9 entries in the hardware DB with "81WE v: IdeaPad 3 15IIL05" reported as running various versions of LL 5.x. so some people have been using the model enough to register it  - maybe with a mouse.

The workaround described on the bug report seems credible but obviously requires the specific hardware to test.

Have you tried completely reversing and removing all traces of your earlier attempts at a solution (or a fresh install) and just implementing the workaround from the bug report ?

If you want to post up your grub file we can take a look.....otherwise, subscribe to the bug and use a mouse

Hi stevef
              Just reinstalled LL6 as changing the Grub settings has messed things up again...
It would be great for an update to sort the touchpad problem out..
Thanks

Have you tried booting any live distros (without installing) other than Lite via USB to see whether the touchpad works?  It might be useful to try some outside the Ubuntu family, e.g. Manjaro, Mageia, Fedora, SUSE.  If you encounter any where the touchpad works, you might be able to identify drivers or kernel options with the live image running.  I say "might" because it might be effort for nothing too based on a prior experience...

Hi WytWun
                I have also tried Manjaro which is Arch based.....  Sadly the touch pad did not work.....
I am positive there is a solution to this....It is just finding it.....  There must be others out there with same laptop running Linux OS not using a mouse all the time..
For many many years i have used Linux Lite on many Lenovo laptops which have very stable and reliable.... 
Thank you for your comments how to solve this......  Looking forward to tagging this as solved on this forum to help others...

Try Fedora and OpenSuSe tubleweed. You tested debian and arch, so that is 2 unique linux distro left.

Hi Mountain Giant
                                  After i read both your suggestions to try.....  I downloaded them both....    Unfortunately both of them again did not work with the touchpad ... But works perfectly with a mouse...
As a shot in the dark....  I also even tried the Puppy Linux......  Again no touch pad....  But it did say.....  "synaptics not found" 
I have not given up.....  There is an solution out there...

A little more info for you. Read through the second link to understand that this is hardware bug with Lenovo caused by its use of an archaic PS/2 chip to handle input devices. Turning off multiplex detection may solve it for you.

Hi trinidad
                Great news.....  The touch pad is now working....  A big thank you for that link...
Here is the solution to the problem....

Open a Terminal window (Ctrl-Alt-T), then copy-and-paste the following three command-lines, one by one...

Code: Select all

G=/etc/default/grub;sudo cp $G{,.`date +%F.%s`} # add "i8042.nopnp=1 pci=nocrs"
sed 's/i8042.nopnp=1 pci=nocrs//' $G|tr -s ' '|sudo dd of=$G 2>/dev/null
sudo sed -i 's/GRUB_CMDLINE_LINUX_DEFAULT="/&i8042.nopnp=1 pci=nocrs /' $G&&sudo update-grub

Reboot your laptop.

I also want to thank all the other people who have tried to sort this Bug/problem......
Much gratitude and appreciation to all
Now i can fully enjoy the outstanding Linux Lite OS
