Problem with the latest kernel?

General Help
1

Today I started my computer using kernel 6.17.0-35-generic. At first glance, everything seemed normal. The system booted correctly and the login screen appeared as expected.

After logging in, the desktop loaded, but I noticed several issues:

The taskbar, which I normally have at the top of the screen, was moved to the bottom.
The Wi-Fi option was completely missing from the system settings.
Brightness controls were also missing.
The only available control was the volume slider.

When I tried to reboot, an error message briefly appeared, but it disappeared too quickly for me to read it.

I restarted the computer and selected kernel 6.17.0-29-generic from the GRUB menu. With that kernel, everything works correctly and all missing features are available again.

Has anyone else experienced similar issues with kernel 6.17.0-35-generic?

I'm sure many have and in future will...but falling back to previous kernel usally corrects problems. you can install a higher kernel. but that would be your call Zorin would still get updated. you would just be on a differnt kernel is all

Unfortunately, this isn't a rare Issue that after a Kernel Update some Stuff doesn't work. When the older Kernel works fine for You, the easiest would be to stay on it. Here are Instructions:

I also noticed a performance issue regardless of whether I boot with the older or newer kernel. The whole system feels like it's running in slow motion. The mouse cursor moves sluggishly, as if it's gliding on ice. The web browser is laggy, and YouTube videos at 1080p struggle to play smoothly, even though I was previously able to watch 4K videos without any issues.

Even Visual Studio Code feels slow and laggy, despite having only a single empty project open. Interestingly, some parts of the system still seem to work normally and remain responsive.

Okay, maybe we should clear some common Questions:

  • Are Secure Boot and Fast Boot in BIOS disabled?
  • Does Your BIOS run in UEFI or Legacy Mode?
  • What Tool did You use to create the Bootstick?
  • Does Your System run in Wayland or X11? You can check that with the Terminal Command echo $XDG_SESSION_TYPE
  • Can You post Your Hardware Specs? (CPU, RAM, GPU etc. If Nvidia: What Driver?)
  • Are all Codec Packages installed?

Secure Boot: Disabled
Fast Boot: Disabled
BIOS Mode: UEFI

I don't remember which tool I used to create the bootable USB, as I installed this system quite some time ago.

Session Type: Wayland

Hardware:

CPU: Intel Core i5-8250U
RAM: 12 GB
GPU: NVIDIA GeForce GT 940MX
NVIDIA Driver Version: 535.309.01

I'm not sure how to check whether all codec packages are installed.

A few days ago everything was working normally, and I hadn't made any significant changes to the system.

Because of the Combination of Wayland, Nvidia Card and the Driver Version., I would suggest to try it with switching to Xorg.

To do that, go to the Login Screen. Click there on Your Profile si that the Password Field appears. When it is appeared, You should see in the bottom right Corner a Gear Icon. Click on it and choose the Option ''Zorin Desktop on Xorg'' and then log in.

As @Ponce-De-Leon suggested using Wayland with nvidia does not go well X11 is more what those vid cards need to work properly..... :grinning_face_with_smiling_eyes:

Even if switching to X11 (Xorg) does not immediately seem to solve any issues, I must point out that the 535 driver and the Nvidia card you are using have no support in Wayland.
Staying on X11 is the proper choice, regardless.

In addition to other issues with the newer kernel - A browser update may have reverted Hardware Acceleration back to enabled for your graphics - that remained enabled even after you booted into an older kernel.
What is your output for

nvidia-smi

In your Browser(s), Settings > Use hardware acceleration when available - Uncheck or set to Disable.
(The exact route to that depends on which browser you are using.)
