how do I start looking for the package I need?
This happens with some mkv files and to all mp4 files I play, both with apt and flatpak installed vlc versions.
this never happened on the same computer with xubuntu 23.10
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.
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 intompv.conf
by removing the--
at the beginning.I don’t know if there’s a way to make mpv autosave this.
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.
