A couple of suggestions:
* respect mailing list etiquette: use plain text, no formatting, and
put replies at the bottom underneath the trimmed text you are replying
to
* don't make us go hunting for info on other sites. Give us the
essential info in your first mail.

I think you have an Ubuntu One account if you are posting on the
forums. Log in with that.

We can't. It needs your computer to fill in the logs, settings etc.
Here's a video that explains how to do it:

Now the Kernel updates are already on 5.4.0.-52 The last Kernel that works is the -42 one that I need to boot with. Soon the system asks me to clean the old kernels so it would be good get this solved soon.

Digging through your replies, reading the forum posts, I am trying to
guess your problem. I should not have to do this.
As far as I can gather:
• You have a Dell Precision M4700, but we do not know what GPU or what driver
• You are running Ubuntu Studio but we do not know what version
• You have a 2nd display but we do not know what it is or how it is
connected or if you've tried other connections
• You do have the latest firmware update
• The problem goes away with an older kernel
• Your system is also losing its wifi connection
If you can fill in some of the blanks I have listed above we can try
to say more.
Meantime, all I can offer are generalisations:
• If you have GPU switching, disable it
• Identify your GPU and install the latest drivers from the manufacturer
• Try a different connection, try a different cable, try a different screen
• Does putting it to sleep and waking it make any difference?
• Have you tried other OSEs/distros? Are they also affected?
Thank you Liam
it took some time toget back to this. So to answer those questions:
*My GPU is NvidiaK2000m
*Ubuntu Sutdio 20.04
*Dell 23* display,but not sure of the model, it's 9 years old. HDMI-DVI cable.
*Not sure of thedisplay firmware
Here behind theselink you'll see the screenshots of Nvidia driver server setting panelbefore and after the kernel updates:

As you can see theselections are narrowed down after the update and the driver version can't beseen.
I also noticed todaythat Virtual Box where I have Windows 7 installed didn’t book andgave kernel related error when I booted with the latest kernel.
However I was ableto make the Dell display come along when I changed the GPU driver tothe generic open source one that is listed as option in UbuntuStudio, but it’s not so good and keeps more noise even with TLPactivated. But when changing back to Nvidia the problem came back.
I'm thinking ofuninstalling the drivers and then updating the kernel and installingthem again, but I wonder if doing more thorough reinstallation would help? I mean doing it through the Terminal removing everything Nvidia related. Or I just update to Ubuntu 20.10.
Thank you in advanceif you have any other recommendations based on that.

Update. I was able to fix the problem by adding kernel headers that were missing. Thank you Liam
anyway.
