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 build on kernel: 5.7.10-050710-generic (x86_64) thanks for the hints on the new GPUs to consider, I'll check to see if they're in line with my budget; I also have to check if they're compatible with my P5QL Pro Motherboard.

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 are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1889377 Title: gnome-shell using lot of CPU (costantly 30% - often up to 100%) making my system quite slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1889377/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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 > prevboot-1.txt journalctl -b-2 > prevboot-2.txt journalctl -b-3 > prevboot-3.txt and then please open a new bug with those logs attached. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1889377 Title: gnome-shell using lot of CPU (costantly 30% - often up to 100%) making my system quite slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1889377/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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 received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1889377 Title: gnome-shell using lot of CPU (costantly 30% - often up to 100%) making my system quite slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1889377/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1889377] Re: gnome-shell using lot of CPU (costantly 30% - often up to 100%) making my system quite slow
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 driver, which is a common problem. It's not a stable and reliable driver for many cards. That why I recommended the Nvidia proprietary driver. A simpler solution, perhaps, is to just get a newer Nvidia card that is supported by the current Nvidia drivers. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1889377 Title: gnome-shell using lot of CPU (costantly 30% - often up to 100%) making my system quite slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1889377/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1889377] Re: gnome-shell using lot of CPU (costantly 30% - often up to 100%) making my system quite slow
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 issues that are coming with it. I installed (freshly new) Ubuntu 20.04 around 10 days ago (after an HD failure without the need to restore any OS data/configuration) and I tried all I knew to make the GPU working: 1) installing the proprietary drivers + putting nomodeset in grub + uncommenting WaylandEnable=false in /etc/gdm3/custom.conf --> result: the system doesn't boot. It keeps staying on the purple/black screen before asking for login credentials 2) I restored the nouveau drivers, removed nomodeset in grub and commented back WaylandEnable=false in /etc/gdm3/custom.conf --> result: the system boots but periodically and randomly, when I do activities like browsing with Chrome, maximizing a window, playing a video (the list is not exhaustive as the problem is not deterministic) the graphic environment freezes for very long time (also minutes in some case), only the mouse is moving and the system may be accessed without delays of performance issues via SSH; killing the process that presumebly originated the problem from SSH gives back control. In logs, the error I got when this occurred was the following: [ 3529.626679 < 2306,035088>] nouveau :01:00.0: fifo: CACHE_ERROR - ch 9 [Xorg[2370]] subc 0 mthd 0060 data beef0201 [ 3628.765241 < 99,138562>] ATL1E :02:00.0 enp2s0: NIC Link is Down [ 3629.628288 <0,863047>] [TTM] Buffer eviction failed 3) to solve problem 2 I have put nouveau.modeset=0 in grub and it addressed the problem (I'm not experiencing anymore that annoying freeze) but, I learn now, originated the problem heading me to you Do you have any idea (or can me route to the proper solving group) on what I can do to address problem 1 or, in case not, problem 2?

[Bug 1889377] Re: gnome-shell using lot of CPU (costantly 30% - often up to 100%) making my system quite slow
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 remove that option from your kernel command line (/etc/default/grub) then run: sudo update-grub and reboot. Separately, I suggest you will get much better performance using the proprietary Nvidia driver. It seems your GPU requires Nvidia driver version 340. To install that please open the 'Additional Drivers' app. ** Changed in: gnome-shell (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1889377 Title: gnome-shell using lot of CPU (costantly 30% - often up to 100%) making my system quite slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1889377/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

In future if you need to configure or analyse extensions, please use the Extensions app (gnome-shell-extension-prefs) and not Gnome Tweaks.
