I am a normal desktop user. Previously using Linux Lite 2.6. Read about Manjaro and I really like the KDE. So Yesterday I tried to install it and I was struggling with issues. After installation it booted to black screen. Tried nomodeset and radeon.modeset=1, Changed to free driver & non-free driver for graphics, nothing worked. I was frustrated. Today again I tried to search for solution and found somebody suggesting to delete the virtual box additional plugin files for installing in Virtual Box and direct install (I couldn't understand it properly) also. But I thought there is some issue with Virtualization, SO I went into BIOS and disabled the Virtualization option and did a fresh Install with non-free drivers. WOW it booted successfully. I updated the system and everything seemed fine.

But I see very High Usage of RAM and sometimes high CPU usage even when the system is idle. When I just trying to figure out the drawing application Kritia , my system freezed completely and I was unable to do anything. Same thing happened while watching video on Facebook on Firefox. I had to hard reset my system. Sometime the usb mouse is turned off, I have to unplug and reinsert to make it work again. Then Only I found my system is using High RAM and CPU. If I just open firefox and chrome the RAM usage increase up to 6 GB.. I have 8 GB RAM.

The Temperature is High and my fans are running loud.

                       (crit = +115.0°C, hyst = +115.0°C)

Please help me.. I love this Manjaro KDE and want to use it as my main system. [b]I am afraid to change the Graphics driver from non-free to free driver bcoz it might give a black screen while booting.. That is I can't boot my system.[/b]

Here are my system details and screenshots:

This is a known issue. Try using free drivers; for most people it reduces RAM usage.
