My hardware: laptop HP Elitebook 6930p, Intel Core duo, stock Radeon graphics controller

My OS sw: Ubuntu MATE 18.04.4

problem description:

  • with kernel 4.15.0-76 resume from suspend WORKS OKAY, as with all previous kernels since first installation of Ubuntu MATE

  • since updating kernel to 4.15.0-88 few weeks ago, resume from suspend DOES NOT WORK, system goes to suspend, but does not resume by pushing the power button, display blinks few times, stays black with cursor in top left corner. Reboot starts system again normally.

  • trying to solve problem by upgrading kernel to 5.3.0-40 but resume from suspend DOES NOT WORK, same problem like with kernel 4.15.0-88. Reboot starts system again normally.

  • now having all mentioned kernels installed, and when selecting kernel 4.15.0-76 in grub, and starting system, resume from suspend works okay when pushing power button.

Seen many similar problem description at site, but not found working solution so far.

What should I do to fix this?

Use 'blkid' to print the universally unique identifier for a device; this may be used with UUID= as a more robust way to name devices that works even if disks are added and removed. See fstab(5).
