Cant run any programs (Lenovo U31)

Hello,
I have a Arch installed ob my laptop (Lenovo) and
I'm using KDE 5 Plasma and SDDM. I have two problems:

1) Sometimes when i suspend my laptop the following screen appears:

When i follow the instructions displayed on the screen everything is normal again.
Is there a way to solve this issue once and for all?

2) After a couple of minutes of using my laptop i cannot open any programs.
When i click on an desktop icon (firefox, dolphin etc..) nothing happens.
When i try to open the console the following error message occurs:

KDEinit could not launch /usr/bin/konsole

Also firefox cant load any new sites when its open. I can close open programs but cannot
shutdown the system with the menubar..

Im pretty desperate, thanks for any help

I would start by reading the journal ( sudo journalctl -b) looking for problems with mounts, dbus, out of memory, etc.
What happens if you try to launch firefox from a terminal window?  After booting, launch your favorite terminal (urxvt, xterm, kterminal,...) and leave it open.  When the system becomes hosed, use the terminal to try to launch a program (like firefox) and see what messages are posted. Share the text of those messages here (not a picture, please)

I would add checking if you are updating the microcode early to the checklist ewaller enumerated.

Re: Cant run any programs (Lenovo U31)

I cant post the whole output of journalctl because I cant copy paste it (error occurs too fast). For what should I look?

when I try to run firefox it says:

No protocol specified
Unable to init server: Could not connect: Connection refused
Error: cannot open display: :0

I tried installing the intel-ucode microcode.

It still happens.

It did that from a terminal window that was running under Xorg?  Or did you attempt to run firefox from a console?

Is Xorg crashing and dumping you out to a console?

Re: Cant run any programs (Lenovo U31)

I attempt to run it from the console then the error message was written under my command.
I used the program 'Konsole' on the normal desktop.

I can start nano from the console normally even when the error occurs. The system is running normal when I dont use wifi or the KDEwallet.
