I did not have this problem prior to upgrading to 19.04. The upgrade process was an upgrade from 18.04 to 18.10 with an immediate upgrade to 19.04 (after a clean reboot), so there was no usage of 18.10 as a desktop environment to compare with. The 18.04 install was kept up to date.
I have tested using the installed linux-image-4.18.0-17-generic kernel and found that there are no problems. During the test process I have noted that there are no problems if the suspend is initiated manually using the top right 'menu' to suspend instead of shutdown or reboot. There is a problem, however, if the suspend is initiated by simply closing the laptop. -- 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/1825736 Title: Mouse scroll wheel barely works after suspend Status in linux package in Ubuntu: Confirmed Bug description: After a resuming from a suspend the mouse scroll wheel is almost, but not quite, non functional. If you scroll quickly for a while you do get a slight movement of the scroll bar to show that there is some level of communication, but nothing remotely usable. The fix is to use the following commands to remove the hid_generic module and reinstate it: sudo rmmod hid_generic sudo modprobe hid_generic Following this all works as expected until the next suspend.
