Kubuntu seems to need for than 4 GB of RAM
by vmelkon from LinuxQuestions.org on (#50K7S)
Is it just me or does it seem like Kubuntu needs more than 4 GB of RAM?
I have Kubuntu 18.04.4 on multiple PCs.
One has 16 GB. The other has 24 GB. The other has 4 GB and another has 4 GB.
After using it for a while, I thought QT Creator was to blame. There would be lots of HDD light activity, the mouse doesn't move or barely moves, the time sometimes does not update.
This could last from 30 min to 5 h.
The PC is unusable and I have to wait or just pull the plug.
However, when just using Firefox for youtube viewing and a few web page searches + using Occular to search in a PDF file yesterday, it happened again.
Libre Office was also open.
I think I had Steam opened as well.
It became unusable for 1 h.
Lots of HDD light activity.
It looks like the HDD has a very high priority in Kubuntu. It disregards the GUI and mouse.
I am trying Linux Mint. So far, so good.
10 Firefox tabs open. Terminal open. Libre Office. xed for text editing. Xreader for PDF viewing.
