In Ubuntu 14.04.5 I did
sudo apt-get upgrade intencionally for holding kernel updates and I installed
nvidia-375 because I have a GTX 740M I know that if I update the kernel, my GPU driver will die, and I will enter in that black screen loop over an over. But something happened...
Why Ubuntu is recommending me AMD/ATI Drivers if I have a NVIDIA GPU?
Can I update the kernel or my changes will be lost?
My laptop is a bit old, it was released in 2013 so that's why in Ubuntu 14.04, the drivers that comes in kernel
4.4.0-31-generic, works fine¹.
¹ I added
acpi_backlight=video because my intel graphics have a bug in his driver, it appears on windows too, see, I have a HD Graphics 4000 so that command in
/etc/default/grub works for manipulating the brightness
