Multiple Graphical Issues on ASUS TUF DASH F15

My laptop is nvidia-optimus powered and has led to multiple headaches regarding Ubuntu 20.04. Currently, the system is in a state where it works kinda fine for a bit, but has frequent graphical glitches for a few frames before returning back to normal; it appears the glitches only occur whenever I move a window or cursor. Usually, these glitches are weird in that one half of the screen switches sides with the other, though sometimes leads to a black-screen crash where the system works perfectly fine (I can still do CTRL+ALT+T to open a terminal) but I can't see anything nor switch tty.

The system uses:

  • RTX 3070 and integrated Intel Xe Graphics
  • Proprietary nvidia driver (nvidia 460 non-server via GUI) with open-source intel driver
  • xorg server that only uses the RTX 3070

Here is more detail about what I did / tried:

  • Arch linux surprisingly works perfectly fine with GNOME and Kernel 5.11 (or so), but I've only tested it with integrated graphics
  • Ubuntu actually wasn't able to boot at all when I first installed it, but uninstalling xserver-xorg-video-nouveau via a chroot forced it to use Intel graphics, then I was able to access the system and install the proprietary driver for nvidia.
  • When a graphical glitch occured, they never showed up in ~/.local/share/xorg/. Haven't checked when it crashes however
  • In Ubuntu 20.04, the same thing happens with integrated or dedicated graphics.
  • Adding nomodeset to the kernel's parameters crashes my system on boot (stuck on ASUS' splashscreen)

I'm stuck on what to do, since I would like to have Ubuntu for specific software. Any help would be appreciated.

The machine relies on quite a few recent kernel updates, which means you will need to install a version of Ubuntu that has kernel 5.14 or newer. 21.10 should give you a properly functional system

Just installed Ubuntu 21.10 and it worked like a charm. Interestingly enough, it's still kernel 5.13? Weird how that works

For anyone else with this issue who still wants to use Ubuntu 20.04, I tried out the PopOS NVIDIA version and it also dealt with the drivers super easily + allowed me to change between discrete and integrated graphics

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
