That was exactly it, it works perfectly now! Thank you! Should I have posted it as a question first, or is this a legitimate bug?

As soon as I booted into the liveUSB, the following started happening: The screen would turn black (but backlit! the display is still on) the exact milisecond that nothing was happening on screen. When I moved my cursor, the image would appear normal again, and would stay that way so long as I was moving the cursor, but the milisecond I stopped moving the cursor, the screen would turn black again. Replace me moving the cursor with any animation happening on screen (cursor loading animation, any loading bars, any window appearing, even animated emojis in the browser, all of these would keep the image displayed so long as they were playing, but the screen would turn to black the exact moment that the animation stopped). I then installed Ubuntu to my system and the same was happening. In tty3, in the CLI, the screen is constantly blinking (I think because of the cursor), and it stays on while I type fast (consistent with the symptoms described above). Everything works normally when booting into liveUSB in compatibility mode. When connected to an external display via HDMI, everything behaves normally on the external screen, but the laptop screen still has the same behaviour explained above. The same problem happens on every ubuntu version from 22 to 25, on linux mint 21 and above, and on the latest version of Manjaro. It does NOT happen on ubuntu 18 LTS, and on linux mint 20.3. What I have tried: -changing the refresh rate, changing the resolution -setting power mode to performance -disabling automatic screen blank in power saving options -changing nvidia drivers to proprietary, then to xorg nouveau, then to older nvidia versions (I suspect the problem lies with the intel integrated GPU) -setting prime-profiles within Nvidia X server settings to use the nvidia GPU -disabling any kind of power saving measure from the bios (UEFI) -updating bios to the latest version I tried asking for help in the #ubuntu IRC, but after a lot of troubleshooting with them, they asked me to submit this as a bug. Thank you! Hopefully this can be fixed so I can enjoy ubuntu on my laptop!
