Series of small questions

Hello everyone,

I've been on Pop_OS for a good week now and I'm liking it. First linux too. I have a series of small questions though and hopefully someone can enlighten me.

Question 1) I have a 3440x1440 screen. The resolution once booted is fine. During boot and up until the login screen, my monitor keeps displaying "HDMI 3440x1440" and flickers as if reset or switched port. I suspect it's because the screens before the login screen are not compatible with that resolution. I have no idea whether I'm supposed to see something or not until that point. Is there a way to "fix" it if there's even anything to fix?

Question 2) Also boot related. Booting anything else but Pop_OS is relatively quiet with the occasional Hard drive working noise. With Pop_OS, my hard drive makes almost uninterrupted sounds as if writing/reading from boot up until well over a minute after login. What is it? Timeshift already working? I'm slightly worried it's bringing extra wear and tear to my drives.

Question 3) Is there a way to display peripherals info? I'm thinking about my wireless mouse battery level. I'm going to dig that info specific for my mouse after work today, but I'm wondering if there's more of a "general blanket" solution to display very basic info from any connected device somewhere. I used to do stuff like that with Rainmeter on Windows.

Thanks!

there can be various file index services that run to allow faster searching of the system.

these typically run in a schedule, but in a new install they may run on the first boot.

after they run the first time, they will run occasionally on a schedule.

I am not sure if time shift does this or not, I never use that tool.

For mouse battery it may depend on the specific mouse and it's drivers.

there are some enhanced mouse/keyboard utilities out such as that 'libratbag'.

This might help with the mouse:

I'm using a 3440x1440 monitor and have no resolution problems on Pop!_OS. I'm not a Linux power user or anything so I probably can't help diagnose the problem but just letting you know that that's not a universal experience

You have to set login screen seperately, or at least did when I changed monitor last. Cant remember what I did, but try this. To be safe I suggest checking you're not overwriting anything on the cp destination, make a backup of the file if there is one

edit: sorry just noticed your a new linux user. To check your not overwriting use ls /var/lib/gdm3/.config/monitors.xml - if it exists it will show it on the return statement. Then cd to directory and use mv to rename file.
