I do have WUBI on my desktop, but that computer is too laggy so I installed WUBI on my Acer Aspire laptop. Everything works fine except the screen is too dark. I tried to reinstall WUBI but nothing. I need to use the flash-light to see what is on the screen. I tried a program called "brightness indicator" . I tried with
sudo apt-get install acpi, but nothing. I updated all my packages and still nothing. Please some help will be appreciated.
Note: Do not ask me about graphics card, i do not know anything about it >_<
