The touchpad stopped working suddenly. At night of yesterday, it was working, but in the morning it was not worked. Before its stop working there were some packages showing there update and asking for the restart of the system. And did not restart that time. After some time I shutdown my system. But after starting the system the came in the touchpad. My system working in dual boot mode with windows 10 also. Touchpad working in the windows 10.

Thank you for taking the time to report this issue and helping to make Ubuntu better.

This change was made by a bot.

[GShyam (ghanshyam99)]

Sorry, but I did not get the solution.
Can you explain the solution a little bit?
And why this happened and what is this bot?

[Chris Guiver (guiverc)]

I suggest looking at the aforementioned link (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854798), and trying what has been suggested there (eg. comment 13 OR 15).

If you try it, and it works PLEASE report back here or on other 1854798 bug report. (this report can be marked a duplicate of the other one; ie. same problem with same fix)

The 'fix' (a reversion) has been found to work on the other s3203/TM2714-002 as noted in the other bug report I linked.

Bots are not people, it's a program running on a machine that looked through your provided files & 'confirmed' at least one other user has the same issue (recorded in their logs). It adds 'heat' to your bug (you'll note the 'heat' for the other report is much higher, it'll thus get more attention).

Hi GShyam,
This issue looks like a duplicate of bug 1854798, you can try the suggestions there, or just boot with an older kernel before the kernel update (e.g. 4.15.0-70). If you think this is not the same issue, please feel free to change the bug status.

Thank you.
