I have a question which seems quite natural but i cannot find anything
useful using google & co.
My (business) notebook has two graphics cards, one builtin identifying
as Intel Iris Xe and an additional one, a Nvidia MX550.
I start X11 (xwin) with defaults (-listen tcp is the only extra option).
Using nvidia-smi and the Nvidia activity dialog i see that the Nvidia
graphics card is not used.
Using glxinfo i see that the builtin Intel Iris Xe is used instead.
I already prefer Nvidia over Intel via the Nvidia control panel.
How do i make X11 and OpenGL use the Nvidia graphics card instead of
the Intel one?
$ man Xwin # See OPTIONS FOR SPECIFYING X SCREENS
In your XWin Server shortcut etc., add server options -multimonitors or
-screen ... after startxwin ... -- ["--" required to allow server options].
Using these options does not change anything.
The XWin server simply doesn not detect the second (Nvidia) graphics card.
I think i will repost with a more concise subject.
