A horizontal line while booting up

ye flag

I just did my first installation of dual boot ubuntu on a separate drive than my windows OS. But everytime I boot into Ubuntu I see a weird horizontal line across the screen just before and after "Enter password" screen.

Image of the problem

I found a similar query but many years old being something related to NVIDIA's drivers. I am very new to all this so please guide me how can I fix that glitchy pixel line. I am using Lenovo legion with GTX 1650 and i5 10300H. ( I did create a new EFI partition on the separate drive than windows and also tried reinstalling ubuntu after disabling secure boot)

Yes, you need to disable Secure Boot in order to use the Nvidia proprietary drivers. No, you don't need an additional EFI partition (no problem if in a different drive, just a waste of space. Now, regarding the problem, does it persist after logging in?

Yes, I disabled the secure boot. The problem is there only while booting up, once I login into the system there is no horizontal line after that.

So, not really a problem.

Switching NVIDIA drivers fixed this issue. Initially I was using "nvidia-driver-460", which was the recommended version by Ubuntu. But I randomly tried changing it just to experiment and set it to "nvidia-driver-450-server" as this was the only option with version before 460. Additional Drivers Though this fixed the original problem I had, I still am not sure which driver version to use, being new to linux I don't have much idea about this.

Update : updated to nvidia-driver-470 and it is fixed in that version.

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.
