Hi guys, I am your new whiny guy in this forum, as you may know this issue from the title.

Here I have HP Folio 13" i5 4GB 128SSD Intel HD3000.

I have installed Kali the same way as this document (Kali Linux Live USB Install: Adding Persistence to Your Kali Live USB).

Everytime I boot up from my USB my screen turns off (or brightness goes to 0) after the boot screen.
What I do to fix this problem is I wait for 1 minute (while the screen is off, yeah I can see through !@#$) then I press (Ctrl + Alt + F1) then I type root (for login) and toor (for password)
Then I type this command "echo 10 | tee /sys/class/backlight/acpi_video0/brightness" THEN BAAAAM MY SCREEN SHINE LIKE A STAR

I have to do this every time I boot up the USB, I tried to alias the command but it doesn't save it after I reboot

Of course I update everything and installed new kernel. I tried all solutions on other forums that I looked at.

If only I can make the brightness file change permanently.

Return 0;
