@Hua Zhang Thanks. On Mint Cinnamon - which doesn't use the Gnome Desktop Environment - I find that, in Dconf editor, there is no 'disabled' option. (Perhaps you were using a terminal rather than the GUI?) However, there was a 'none' option. Selecting it . . made no difference to the problem. Note that, at least on my system, the problem occurs only after a fairly long (>10 minutes?) period of sleep. Still, I did not try to combine this ostensible fix with any of the many others that are floating around.
Note also this irony: after this webpage has 'slept' - been inactive for a while - trying to post a comment generates this error: (<Bug at 0x7f2b2a450550>, 'newMessage', 'launchpad.Edit'). Well, unless the problem was caused by my pinning the tab in Firefox. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1791427 Title: Touchpad and/or trackpoint stop working after S3 suspend on Lenovo X1 Carbon 6th Status in linux package in Ubuntu: Triaged Bug description: Ubuntu 18.04.1 Terminology in case we use different terms: touchpad - just the rectangular touch-sensitive surface below the keyboard (xinput lists it as Synaptics TM3288-011) trackpoint - the red thingy built into the keyboard + 3 physical buttons below the keyboard (trackpoint and buttons are integrated together; listed in xinput as TPPS/2 Elan TrackPoint) On September 7th, 2018, Lenovo has issued a BIOS update (v1.30), which enables proper S3 deep sleep state - users no longer have to patch DSDT tables to get it. It can be enabled in the BIOS settings. In X1 carbon 6th generation models that have NFC, when laptop wakes from suspend by opening the lid, in most cases both touchpad and trackpoint stop working completely. They are also no longer listed when running xinput command. Sometimes just one of them stops working, usually the trackpoint. In some rare cases it is possible to bring them back by using these commands: echo -n none > /sys/devices/platform/i8042/serio1/drvctl echo -n reconnect > /sys/devices/platform/i8042/serio1/drvctl rmmod psmouse modprobe psmouse These worked properly when waking up from S2Idle sleep state (had these in a script that runs after waking the machine from suspend), but with S3 deep sleep these rarely work and the only way to bring back touchpad and/or trackpoint is turning off the machine and turning it on (restart does not help). I could not find any pattern that would show when the input devices stop working or start working again using the commands mentioned above. It's completely random from my perspective. This is happening on the standard issue 4.15.0-33-generic kernel that shipped with my Ubuntu 18.04 (with updates), as well as with newer mainline kernels, such as the newest point versions of 4.17, 4.18 and 4.19 RC2. This happens regardless of whether "blacklist i2c_i801" is commented out in /etc/modprobe.d/blacklist.conf or not. It happens regardless of whether "psmouse.synaptics_intertouch=1" is passed as grub parameter. Presence of TLP does not make it better, nor worse. It appears that non-NFC models are not affected. I know at least one Arch Linux user who has the exact same model, but without this issue. I'm using synaptics driver (no libinput installed), he uses libinput and doesn't have synaptics, if that information is of any use. Libinput does not seem to help.
