I don't know the answer offhand, but one thing I would do is see whether Mpv is equally effected. By default, the number keys 1-8 will control those settings.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

thanks, now I know how to play with mpv.
However, each time I close the program, changes I made to those settings are lost. Is this how mpv works?
You can set the default brightness in mpv in ~/.config/mpv/mpv.conf like this:
brightness=-10
Look in the manpage (man mpv) for other settings. I think any option like --brightness=-10 can also be put into mpv.conf by removing the -- at the beginning.
I don't know if there's a way to make mpv autosave this.
thanks
Can you check what video driver you are using? You might be on some kind of software renderer.
What does
glxinfo | grep renderer
say?
that command returns
GLX_MESA_copy_sub_buffer, GLX_MESA_query_renderer, GLX_MESA_swap_control, GLX_MESA_copy_sub_buffer, GLX_MESA_query_renderer, GLX_MESA_swap_control, Extended renderer info (GLX_MESA_query_renderer): OpenGL renderer string: Mesa Intel(R) HD Graphics 620 (KBL GT2)
This looks good.
I don't know how to figure out on vlc what sort of output method, codec, or hardware acceleration it's currently using, so I second the other person who recommended mpv.
