18.04 crashes when coming back to GUI

I’ve read the article Switch to Console in Ubuntu 18.04 – How to Leave GUI? and this question.

I need to be able, while logged-in in the GUI, to go to tty and come back to GUI.

Here is what I do:

  1. I am in the GUI logged-in
  2. I press CTRL + ALT + F3 and I get the tty. I log in to this tty.
  3. Then I press CTRL + ALT + F1 and i get the GUI login screen. I put my password, I click “unlock” and it crashes. Nothing moves. Frozen screen.

I’ve also tried to go back to the gui with ALT + F2instead than CTRL + ALT + F2 – in this case it freeses in the tty.

Only hard reset can bring me to normality after reboot.

Please help me to resolve and in case of need to troubleshoot it. I don’t have idea where to find the logs if needed.

Why are some of my CQWPs coming back blank for Visitors?

I have a page with approx twenty CQWPs on them, all coming from the same library. It looks fine to me (Admin) but for the Visitor permission group, some boxes are coming up blank – no error message, just nothing! The header is still there and there is no error message. I’ve checked the library documents and there are no permission problems, and when I recreate one of the blank CQWPs (new web part with the same search parameters and display settings) the Visitor is still unable to see them. This does not appear to be a problem with web parts not set up with these settings. I’m at a loss! Grateful for any help.

Am I protecting myself well or can I still be traced back to?

I am practicing penetration testing as a newbie on a website (which allows this), and would like to know what traces I can leave that could be used to trace back to me.

My setup consist of: • My laptop which uses Ubuntu as a host OS. • Kali linux inside a virtual machine. ∆ This will be a temporary OS that I will delete after the attack. • An external wifi adapter with a spoofed MAC and IP address. ∆ I use an external USB wifi adapter so I am not using the network card built into my laptop which is tied to laptoo identity. ∆ I spoof the MAC address using Macchanger on both the internal and USB wifi cards so the real MAC address is not used. ∆ I spoof the IP address which i do by creating IP packets which have a modified source address in order to hide the identity. • Proton VPN. ∆ This is to not reveal my real location, since a spoofed IP and MAC address would not change your location but only the identity of the network card. • Connected to a public wifi with no account creation. ∆ In case of a trace back to my location even if a VPN is used, it would not be my home or some other identifiable location, but instead a network with a lot of other users. • I have no identifiable files on my real OS in case the trace broke through the VM.

I would like to know how I could still be identified as a person even though I use all of the above protections, and how the trace could break through the VM?

How to turn touch pad back on using keyboard

I managed to turn off my touch pad and looking for a way to turn it on.

I tried windows key and managed to search settings. But display is selected and could not figure out how to navigate between settings.

My ultimate solution was to connect another usb mouse and switch on turn pad. But I more interested in switching on or off touch pad in GUI using keyboard or from terminal.

I experimented with tab key when mouse was selected and looks like I can turn it on using tab and space combo after some experimentation. However UI, at least on my machine does not provide any visual cues about which item is currently selected.
