Description iqbal 2017-08-19 04:13:44 UTC
I have 16GB DDR3 type RAM memory space on my laptop (2 slots of 8GB) and a normal installation of the latest version of Manjaro Linux 64-bit version that comes with KDE pre-installed. I am fascinated with the DE and its features that's why I've been using it since 3 weeks and been applying some tweaks like Virtual Desktops, Keyboard Shortcuts, Effects, Appearances, Widgets, etc. I hadn't even touched the Power Management settings displayed inside the "Hardware > Power Management". 

Then I noticed something abnormal with my RAM and CPU usage, laptop fans starting to sound loud, HTOP started to report huge amounts of RAM being used (which is the main problem) on processes like "org_kde_powerdevil", "kded5", "plasmashell", "kscreen_backend_launcher" (sorted by decreasing percentage of RAM used, the most is 'powerdevil'), crashes. Even when I am not using my computer for hours (running some background programs like qbitorrent and cantata though), I could've noticed how this processes 'consume' the perfomance of my computer and lead to a crash or to get extremely slow. Here are some cases when "powerdevil" and the other processes start to "accumulate" RAM and computer becomes slow:

 - Closing the laptop's lid (This is why I set 'Lock screen' for the 'When laptop lid closed' option under "Hardware > Power Management", don't know if it is OK)
 - Switching ttys (e.g. Ctrl+Alt+F6)
 - Logging out
 - Suspending
 - Laptop being used for hours without happening any of the above.

Every since I restart the laptop, RAM usage returns to normal.
Of course I had all packages updated, and I am using the LTS recommended kernel version of Manjaro. I preferred not to use a Swap partition since it can make my HDD slow and lead to waste.
