This could mean alot. It could be an extension, it could be a add-on. it could be the video being processed by the cpu. (when you move the screens around, xorg - lightdm jumps, so does mine, unless i have an external video card) but you are correct as to the lightweight cpu. but what i5 series do you have? What is the CPU model (different series’ utilize different GPU’s and handle onboard video differently)(type this in terminal: “sudo dmidecode -t 4 && lspci | grep VGA” and please post results)<–You could see if the Onboard Graphics is compatible with Parrot or if there is a fix for it. <— As to if the onboard Graphics. (perfect example) ie:
My results: (shortened to point example)
sudo dmidecode -t 4 && lspci } grep VGA
“Version: Intel® Core™ i7-3770S [email protected] 3.10GHz”
“00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev09)”
But my true Onboard Graphics is: Intel HD Graphics 4000
I vaugly remember searching for a solution to installing linux drivers for HD 4000 and i hit a brick wall. Either way the graphics on this does sufficient enough unless i want to game, then i hook up my 1060i and rock out.
The system monitor app at the top is a wonderful addition to the OS, works great, and is small. The only thing that could be better for it is the update of the CPU usage to realtime, but i am sure that the programmers made it that way intentionally because the applet takes CPU usage. Understand? You are able to modify the settings for that applet, just right-click and click Preferences. In conclusion of that said, is the actual hover indicator of the applet, is behind in the actual, real-time results, like HTOP, but HTOP takes more CPU usage.
“The terminal itself also makes me go to a huge amount of CPU usage and whenever I try to do something like access Users and Groups or anything like that, it freezes for a while.”
I would have to see that in action to attempt to determine what that could be, but in conclusion to this, what i am trying to say is that from the info you have provided, so it MAY be the compatibility of the onboard video graphics of your CPU and Parrot. (freezing, opening new windows, please post the results of the previous command in terminal, and maybe we can find a trusted driver for your On-Board Graphics…
