After installing Ubuntu on my HP pavilion DV6 through CD version 16.04 and erasing Windows, computer turns to black screen everytime I boot. I have done some research and the fn+F3 doesn't seem to work (increasing brightness) my computer is quite old and the F10 key for example doesn't work... The only option I have now is to Press escape while boot Press E to change parameters Erase "quiet splash" either for Nothing or for "acpi_backlight=vendor" .
"nomodeset" also allows me to start the computer and use it normally. What I would like now is to save these changes so I could start the computer normally with no manipulation.
The problem is I can't seem to find a way to save these changes and make them default. Thank you for your time and attention !
