I recently needed to help install Debian on an Acer Aspire ES1-522 laptop. There were quite a few issues to do with drivers.
The commands to fix the different problems are below. The nonfree section needs to be enabled for the drivers.
- Fix wifi not turning on:
echo blacklist acer-wmi | sudo tee -a /etc/modprobe.d/blacklist-acer-wmi.conf
- Fix backlight control:
sudo sed -i 's/GRUB_CMDLINE_LINUX_DEFAULT="quiet/GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=Linux acpi_backlight=vendor/g' /etc/default/grub && sudo update-grub
- Install graphics drivers:
sudo apt install firmware-amd-graphics
- Install wifi drivers:
sudo apt install firmware-atheros
- Install bluetooth drivers:
sudo apt install firmware-realtek
