Hello,
after the last update of zorin it dont start anymore.
When I start Zorin normally
But when I start Zorin with this
Does anyone has an idea why it dont start normally anymore? And how can I fix this?
MFG
A lot of people are finding the new 6.8 kernel has conflicts with their machine, especially now Wayland is being used in place or Xorg. Could be Nvidia, if you have that... Keep using the older 6.5 kernel as it works on your device.
I'm sure someone will answer with more technical details soon.
ok, thanks. 
But is there a way to start in the kernel 6.5 by default?
I have a Nvidia Georce RTX 2080 Ti
That will be your conflict then - it's a common problem.
I hesitate to give advice about having the 6.5 kernel start by default - but if it were me, I'd roll back the system using Timeshift and "hold" the 6.8 kernel update using the software manager / updater (ignore / hold back anything connected to the 6.8 kernel), and then update anything else that got rolled back.
Another good idea is to search this forum for similar posts - there have been a lot, and you'll find some good solutions from more experienced members.
I cant find any similar posts.
I would wait if someone has an Idea on how I could start in 6.5 by default, but if no one replies, then I would do your solution.
That's a very good idea.
I'll also try and find a similar problem as I've read a few. If I can I'll post a link here.
Edit
@Toedliches_Auge, if you read the whole thread you will understand better the problem you're facing, even though the topic looks different, it's full of information regarding the 6.8 kernel update and conflicts with Nvidia, among others, and advice on using the 6.5 kernel.
AZorin explains here the Thing with the 6.8 Kernel and Nvidia Drivers:
And here is a How To to set an older Kernel to default boot:
Ok, thanks booth.
I would try the driver thing first.
I have the corrct driver, but it dont work.
So, You have changed to the 6.5.0-45 Kernel, yes? And now You want install the Nvidia 535 Driver? Did You uninstalled the previous Driver before You selected the 535 driver in the Drivers Tab?
Yes I am in the 6.5.0-45 Kernel.
And I changeg nothing on my drivers, this is all default. But it looks like the Default driver (535) should work according to the post. But it did not work with it.
Have you any ideas what I could do?
Have you tried rolling back with Timeshift??? If not, there's nothing to lose...
no, but I want to first try to make the new kernel work with my computer (if that is possible).
Hmm ... Okay, let's try this in the Terminal:
First type sudo apt remove nvidia* libnvidia* to remove eventually installed Nvidia Drivers. And then type sudo apt install nvidia-driver-535 to install the 535 Nvidia Driver.
Ok, I now have done it.
When you have tested it, come back and tell us if it works.
The driver works with the old kernel, but unfortunatly it does still not work with the new kernel.
Have you any other ideas?
