            Bug ID: 488093
           Summary: Plasma gives no feedback if the system cannot
                    hibernate successfully due to lack of swap
    Classification: I don't know
           Product: kde
           Version: unspecified
          Platform: Arch Linux
                OS: Linux
            Status: REPORTED
          Severity: minor
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: corroddity at proton.me
  Target Milestone: ---

SUMMARY

Selecting the hibernate option in the application launcher or the lock screen
when there is not enough swap space available will result in no response from
KDE. 

When using systemctl to trigger a hibernate, it will report an error:
> $ systemctl hibernate
> Call to Hibernate failed: Not enough suitable swap space for hibernation available on compatible block devices and file systems

However, KDE will simply do nothing. This is very confusing, as without any
error messages or notifications, the user will be left with no idea as to why
their system is not hybernating. KDE should display some sort of feedback to
indicate that an error has occurred when hibernation has failed.

STEPS TO REPRODUCE
1. Disable all swap space, or run some load that causes your swap to be used to
the point that you cannot hibernate
2. Click the hibernate button on the application launcher

OBSERVED RESULT
Nothing happens.

EXPECTED RESULT
Some kind of popup or notification appears indicating that an error has
occurred
