[ SOLVED ] Lenovo IdeaPad-3-15IIL05 No touchpad

[carlam]

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

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 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...

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

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...

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 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
Carl
Here is the Grub file
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

# Linux Lite Grub background
GRUB_BACKGROUND="/boot/grub_linux_lite.png"

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

I edited my post to include an Ubuntu bug so the information may have crossed - is this report a match to your problem?

My problem is the same...

[carlam]

Just done this grub update GRUB_CMDLINE_LINUX="i8042.nopnp=1 pci=nocrs"    Still no touch pad...

[carlam]

Other things i have done...
Tried up to date kernels and some older ones..

Changed a few grub settings which was recommended on forums  which crashed the system..

Tried this one....   GRUB_CMDLINE_LINUX_DEFAULT="i8042.reset quiet splash"   But did not work...

On both versions the touchpad did not work in live media.....   I was hoping that when i did a full install fully updating the system in would sort its self out..  I was wrong...

[stevef]

When you first booted 5.6 and 6.0 from live media, did the touchpad work during testing the system prior to installing ?

edit ->  Not sure if the links provided by WytWun reference this, but it seems a close match

I've been bitten by Lenovo touchpads in the past (Ideapad 100-11IBY) and eventually the necessary drivers caught up to the oddities.  There are some things that seem to have been successful with Lenovo touchpads generally and your model specifically.  So, to give people an idea of what you've already tried - have you tried the suggestions at the following links:
