Can’t open GRUB in ubuntu 18.04

Its a dual boot i.e. windows 10 and ubuntu 18.04. Ubuntu is filled as preferred choice hence GRUB doesn’t come by default.
I went through many resources available and they all said press shift before the logo of ubuntu appears i.e. while the manufacturer logo is there in the screen( in my case its Lenovo ).
I have tried tapping shift continuously , long pressed shift and even kept it pressed before turning the computer ON but in none of the cases GRUB window opened. Have tried it with both left as well as right shift.I am trying to open ubuntu’s recovery mode.

Dualboot problem with windows 10 and ubuntu in MSI

I have installed windows 10 and ubuntu 20.04 on my laptop, in general it seems that everything works fine.
The problem I observe, is when I’m in ubuntu, and I reboot to enter windows, there are configurations that are reset, like configurations with the graphic card (nvidia), sound card or wifi.

Similarly, when I’m in windows and I switch to ubuntu, the first time I log in, the wifi card never works in ubuntu, I have to reboot twice for ubuntu to detect it…

I was reading that this may be due to the UEFI configuration, which should be using legacy mode. Should I format the disk, switch modes, and reinstall windows + ubuntu?

Also, in other computers I’ve had, I used to have problems changing the time, when I changed OS, but in this case, I find it curious to observe that not only the hour changes but also the minutes, I don’t know if it’s something also rare.

I’ve put all the problems together because I don’t know if they are all due to the same mistake…

Thank you very much in advance

How to partition hard drive in Ubuntu 20.04

I’m literally brand-new to Linux and Ubuntu, so please forgive my ignorance and bear with me here. I purchased a Dell Inspiron 5593 recently and immediately installed Ubuntu 20.04 on it. Long story short, the keyboard is screwed up, and the place I bought it from won’t service Linux OS. Gotta be Windows/Mac OSX for some stupid reason.

So now I’m trying to partition the hard drive and reinstall Windows on the the partition. I’ve checked out GParted, but I haven’t been able to follow the documentation. For example, I don’t see any unallocated space on my disk, and I’m not willing to unmount my main disk without knowing what that will do to my computer.

Honestly at this point I’m ripping my hair out and would just appreciate some clear instructions on how to partition a hard drive in Ubuntu 20.04 because I’m clearly too technically illiterate to understand GParted’s documentation.

Easy way to bypass password on my computer

I was not able to formule a question so maybe this was already solved, and if that’s the case, sorry.
But I found a huge vulnerability on my computer. It’s a portable computer with a Win10/Ubuntu 20.04 dual boot.
When I’m logged in, and that I lock my session, this sends me to the login screen, okay. But then, if I do Ctrl+Alt+F3 to go to the terminal mode, and then do Ctrl+Alt+F7 to leave terminal mode, this simply unlocks my session !
It doesn’t work at computer start though, the session must be started and locked.
Note that when I close my computer this doesn’t lock my session even if it’s activated in the settings.
This is a critical vulnerability but it’s doesn’t work at all on my friend’s computer which is also a Win10/Ubuntu 20 dual boot.
I don’t know why this happens to me, any idea of solving this ?

Thanks for you time

ANSWER

This does not seem to be a normal behavior from what I’ve experienced at all as far as I can remember. I know before I was fond of having my Linux desktop auto-login on startup. I think I also opted to have it login automatically after sleep/suspend. Perhaps the switch to a different TTY/console constitutes as the same behavior. This looks a lot like buggy behavior to me.

I would go so far as to document on how to replicate it, and report it as a bug. Call the attention of the developers so this can be looked into and fixed if necessary.
