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 0000:01:00.0: fifo: CACHE_ERROR - ch 9 [Xorg[2370]] subc 0 mthd 0060 data beef0201 [ 3628.765241 < 99,138562>] ATL1E 0000:02:00.0 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? Thanks again for your support.
