Yes, kernel 5.7 is too new for nvidia-340. You will need to go back to the official Ubuntu kernel (5.4) first. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1889377 Title:

I tried to reinstall drivers and now I'm getting another error (see attachment), in particolar it seems there is some compatibility issue with the last version of kernel: ERROR (dkms apport): kernel package linux-headers-5.7.10-050710-generic is not supported Error! Bad return status for module

Also you might have been hitting bug 1872159. To work around that try removing 'splash' from the kernel command line. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1889377

You might want to consider the current cheapest Nvidia cards for sale: * GeForce GT 710 (2x as fast as the GeForce 9600) * GeForce GT 1030 (7x as fast as the GeForce 9600) Both of those also support the latest Nvidia drivers (version 450). -- You received this bug notification because you

We would need to see the system log from one of those failed boots. To do that please: 1. Reproduce a failed boot with nvidia-340. 2. Uninstall nvidia-340 and after rebooting collect the log from the previous failed boot. For example, to collect the last three boots run: journalctl -b-1 >

1) Yes, sure, I have installed nvidia-340 but I get the described result :-( --> do you know anything I could do to detect what goes wrong and to repair it? 2) I know and that's why I also would prefer option 1, but not working I went for option 3 (which is less worse than 2) Thanks. -- You

1) Make sure you are using the nvidia-340 driver, which is what your card requires. Newer Nvidia drivers probably won't work with that card. If you still get stuck with a system that doesn't boot properly then please open a new bug about that. 2) The freezes appear to be bugs in the nouveau

Hi Daniel, and thanks. Let me give you some history to explain why I had configured it like that, in order to understand if you could help me or router me to the proper support. I've been using Ubuntu for around 4 years now and I've collected some background on my GeForce 9600 GPU and the

I found the problem. Your system only has one GPU (GeForce 9600) which it needs the 'nouveau' driver to use. But you have disabled the 'nouveau' driver in your kernel command line: nouveau.modeset=0 and so gnome-shell is using software rendering, hence high CPU. So this is not a bug. Please
