Description Clay Weber 2020-11-03 22:10:40 UTC

SUMMARY


STEPS TO REPRODUCE
1. Install Neon using the automatic full disk partitioning option 

 

OBSERVED RESULT
Calamares sets up a 21Gb swap partition on my laptop with 20Gb of ram.


EXPECTED RESULT
Either a swap file, as is done on most Ubuntu variants, or a more sane swap partition size. Unless Neon has hibernation enabled, this is quite overboard.
IIRC Ubuntu have hibernation disabled by default.


SOFTWARE/OS VERSIONS

Linux/KDE Plasma: KDE neon
KDE Plasma Version: 5.20.2
KDE Frameworks Version: 5.74.0
Qt Version: 5.15.0

Yes, it does have hibernation, and what's why the swap partition is so big: the swap partition has to be as big or bigger than the amount of RAM on your system. Ubuntu uses a smaller swap partition (a file, actually) because they explicitly don't support hibernation.

Whether or not hibernation is a good default is a different question. Perhaps it should not be, or perhaps there should be an option in the installer. Those would be separate issues that require separate bug reports though. :)

Thanks for clearing that up!

But it does bring to the front that Neon is straying a bit from stock Ubuntu base, which many  assume to  have certain characteristics, more so if the user doesn't look at the dialogs fully, expecting the same results as previous installs.

I do not recall noticing this on my previous install some months back, or in virtual machines in recent months. Can I assume this may be a somewhat recent change?
