Somewhere in this long thread, I think, an engineer suggested the following.
Somehow, in my particular case - a case in which, on my ThinkPad X1CG6, no work-arounds worked and neither did the test version of the kernel patch - my motherboard was at fault. Well, the engineer was right. For, I got my motherboard changed - for another reason - and 'deep sleep' now works properly. Now, as it turns out - and the engineer who changed the motherboard did not tell me this - the new motherboard has a different model number to the old one. So either Lenovo has fixed the problem with a new version of the motherboard. Or else my old motherboard had an idiosyncratic fault. By the way, did the kernel patch for the problem ever get merged? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1791427 Title: Touchpad and/or trackpoint stop working after S3 suspend on Lenovo X1 Carbon 6th To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1791427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
