Screen goes BLANK after Display Changes

[Aditya_Pie]

Hi,

I was installing Parrot os on a Lenovo tab(IdeaPad D330) and after installation the screen was rotated 90 degrees and if I try to revert it back in the preferences the screen goes blank and I have to restart to get some display output… Even then the screen stays rotated 90 degrees… Does anyone have any advice or any solution to this issue or facing the same issue. I really wanted to use parrot os but it is pretty difficult to use it with these display issues… I have even attached a pic of it…

Thanks,
Aditya

Hello. Using xrandr to rotate the screen what happens? Type xrandr -o left.

Still the screen goes blank… Like when I type it in the terminal the screen turns off and then turns back on but its blank not even the cursor is visible until I restart it

Try logging in with terminal using CTRL + ALT + F1. Then try:

sudo systemctl stop lightdm (or whatever desktop you are using, sudo systemctl status)
then sudo apt-get update && sudo apt-get upgrade

sudo apt --fix-missing update

sudo apt update && sudo apt install -f

sudo update-initramfs -u

reboot
