Press enter or control d?
Either - I always tap enter, myself.
Now how to exit
ctrl+x should exit...
then the y key to say "yes to save", then the enter key to save the current configuration.
Yes i did that then how to reboot
Or do i choose resume?
Resume is fine, since you have not yet completed boot, it should boot as normal.
And i will change to kernal 5.15m
It is still stuck
What about on the 5.4 kernel?
I dont have kernal 5.4 i have 5.15 and 5.13
Oh... thought we tried that earlier...
Did you run sudo update-grub after removing nomodeset?
No i didn't
Well i will do it
Yes, as above:
It is fixed now 
Now how i will fix the freeze
What about these?
My laptop is not overheating so
How do i disable hardware acceleration
Not overheating*
What makes you certain? You should actually check the temp of GPU
sudo apt install lm-sensors
sudo sensors-detect
There are also apps you can use psensor or xsensor apps
sudo apt install psensor
what do i do with this command?
