Ubuntu Acting Very Strange

[akslnrdn]

Hello everyone,

I am using ubuntu 18.04. Did not experience issue until today. O.S started to act very strange. Opening tabs.. also deleting the text that i am typing right now. My desktop icons and folders gone (dissappared). Folders almost freezing. I tried to update but did not worked. Is it related something to hardware or software ? The last thing that i did was, copying large files from portable hdd to my computer (temporary)... And the laptop disk now is almost %90 used. I thought that the disk full capacity makes the problem. I have deleted some files but the the problem still exist. Please help me. Thanks in advance.

Here is my desktop screenshot. Icons and folders are disappeared. As you can see some of the options of mouse (right click) are not available. And more and more other stuff that i cannot describe here.

I doubt if the cause is lack of hard disc space. I see root ( / ) = 323G available and /home = 245G available. Try opening System Monitor and check how much memory is being used and if the CPU cores have a high usage.

Large images can take a long time to download and may actually cost users in extra fees. Use a thumbnail and let other users choose whether or not to expand them.

If you need to include an image, please use the attachment facility provided by the paperclip icon above the text entry box. This will add an expandable thumbnail to your post.
