Screen stuttering when using nouveau or nvidia drivers

Hi everybody,

I've just installed Debian 10 (without any Desktop Environment because I wanted to install the i3wm) on my notebook Asus G75, in BIOS mode.

As soon as the system booted up for the first time, I installed Code:xorg, xorg-dev, build-essentials, linux-headers-4.19.0-6-amd64.
When I tried to install the NVidia driver I've gotten from https://www.nvidia.com/Download/driv...x/137276/en-us by running Code:sh nvidia.run I found out that there was an error when building the nvidia-drm module.

So I switched to the nouveau driver, installed Code:i3, compton and after having configured i3 to execute compton on startup I tested my screen by using this tool https://www.testufo.com/stutter#demo...000000&pps=720 and I get video stuttering: it's like the lines are going back and forth for ~30 pixels very quickly instead of going forward.

So I tried to install the nvidia driver from the Debian package repository: I installed nvidia-detect which advised me to install nvidia-legacy-390xx-driver. When I did it, rebooted the computer, I get the very same screen stuttering effect, even after having configured the nvidia driver with nvidia-settings.

That's my hardware configuration:
Code:00:00.0 Host bridge: Intel Corporation 3rd Gen Core processor DRAM Controller (rev 09)

04:00.0 Ethernet controller: Qualcomm Atheros AR8151 v2.0 Gigabit Ethernet (rev c0)I also have two screens, but I'm only interested to keep the external one, as I use my notebook as a workstation.

And my software configuration is this:
- i3: the configuration file is the default one, except that I added this line near the beginning of the file Code:exec --no-startup-id compton --config ~/.config/compton.conf -CGb --backend glx --paint-on-overlay --vsync opengl-swc-compton: I copied and pasted this configuration file: https://www.reddit.com/r/linuxmaster...on_this_might/

EndSectionDo somebody have a fix? I'm quite desperate, as I've also tried to install Debian with GNOME and with KDE and I get the same artifacts with nouveau (I must admit I haven't tried the nVidia driver in that situation)
Moreover, I know I was able to configure it right the last time: I managed to install it from the .run file provided by NVidia, but I had some hardware problems a month ago and I had to change disk (and therefore to reinstall Debian). I still have the old configuration files, but they don't solve the problem in this installation.

Thanks a lot.
