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].
