System Freeze after sometime

[waffen]

I just installed the old kernel and... all was broken when I restart the PC, screen at 600*480 res, only recognize 1 monitor (HDMI) the other one not even listed... I know it's because the Nvidia drivers are not compiled against that kernel (right??)

Monday I start a new project and I can't expend more time in this problem, I'll going to format and reinstall the hole system

Really a BIG THANKS!! to all of you for your time and help! I really appreciate it!

Saludos!! // Greetings!

You can boot to the kernel 5.11 in GRUB by pressing 'e' after you have chosen the entry for 20.04 and entering the version number for vmlinuz-5.11.0-37-generic and initrd.img-5.11.0-37-generic.

I found following in Web:

Ubuntu – 20.04 Focal – Nvidia driver no longer loading with kernel 5.4.0-42

driverskernelnvidia

On Ubuntu 20.04 Focal, I upgraded to kernel 5.4.0-42 (using the Software Updater GUI / apt) and my Nvidia proprietary drivers stopped working.

Rebooting to the old kernel (5.4.0-40) yields a working system, so it is clear that the kernel update was the trigger for the problem.

Installing the headers with:
sudo apt install linux-headers-5.4.0-42-generic

caused apt to automatically recompile the nvidia kernel module for the new kernel. After a reboot to the new kernel, everything just worked.

I'm not sure why headers weren't installed automatically (I believe they usually are?). Perhaps there is a problem with the apt package for the new kernel?

This happened on the 20.04 Focal release.

so one have to execute:

sudo apt install linux-headers-generic

to recomplie the nividia kernel module for the 5.4 kernel.

Hi again... guess... yes! Again the freezes!!

I just format + clean installation of the last Ubuntu version, I notice the installer don't create a swap partition but in the system monitor I can see 2GB for swap... well...

The only thing I installed was the Nvidia driver 470.63.01 start Firefox (not login into my profile so no extensions installed) and start watching videos.. system freezes. Log image attached

What do you think? is it the driver? do I need to install the other one available? v. 460?

List of drivers:

I'll keep my pc ON but with the Firefox closed...

Ok I just install the 460 driver all fine I put a long video running, fine till the screen go black or I press win +H to activate the screen protector... Looks like it's the problem.
I see the same problem many times with other driver too.

Any ideas?

My idea was to install 5.4 kernel in 20.04:

sudo apt install linux-generic linux-headers-generic

boot into 5.4 kernel and install the nvidia driver if not done automatically.

Recent Ubuntu versions create a swap file instead of a swap partition.

bin    dev   lib    libx32      mnt   root  snap      sys  var
boot   etc   lib32  lost+found  opt   run   srv       tmp
cdrom  home  lib64  media       proc  sbin  swapfile  usr

what results in after the screen go black or freeze:

dmesg|grep nouveau
