I think I made a big mistake. This is my first experience with Linux, and I made the terrible choice of relying on an AI to solve a specific problem, which quickly turned into a huge problem.
It all started when I tried to use Vulkan in the Dolphin emulator. Some errors occurred, and the AI suggested that the problem was probably the Nvidia MX550 driver. It told me to uninstall it and use the sudo ubuntu-drivers autoinstall command. However, this installed version 595 of the driver, which resulted in a black screen with no video output.
I booted the system into recovery mode and, unfortunately, followed the AI's suggestion to switch to the Nouveau driver to be able to access the graphical environment. But, among the commands it gave me, one of them simply deleted important parts of the kernel, breaking all my USB ports and Ethernet functionality, as well as uninstalling all my drivers.
I managed to boot an older kernel version, reinstalled the problematic version, and, after gaining internet access, ran a package recovery.
In short, after all this humiliating and embarrassing situation I created, my system simply isn't working as well as it used to. In fact, the MX550 doesn't even appear in the Vulkan graphics card selection options in Dolphin anymore, so the initial problem hasn't been solved yet. Also, my laptop is noisier now; before this, I almost never heard the fan, and it always ran much cooler.
Is there any way to restore my system to its previous state without having to do a complete operating system reinstallation?
