Have you tried installing the optimus under Buster

Looking in my notes, it looks like I tried installing nvidia-legacy-390xx-driver in January. I do not see any URL for instructions. The Debian wiki page for Optimus does not look familiar:

   https://wiki.debian.org/NVIDIA%20Optimus


In any case, my fumbling around only made things worse. So, I wiped the SSD and did a fresh install KISS OOTB:

    Insert debian-10.8.0-amd64-xfce-CD-1 USB flash drive.

	Debian GNU/Linux installer boot menu (BIOS mode)
						Install
	Language				C
	Continent or Region			North America
	Country, territory or area		United States
	Keymap to use				American English

    Pop-up dialog:

	Detect network hardware

	Some of your hardware needs non-free firmware files to operate.
	The firwmare can be loaded from removable media, such as a USB
	stick or floppy.

	The missing firmware files are: iwlwifi-60000g2a-6.ucode
	iwlwifi-60000g2a-5.ucode

	If you have such media available now, insert it, and continue.

	Load missing fimrware from removable media?

    Insert USB flash drive "usb64a" with "firmware" subdirectory
    containing Debian 10.8.0 firmware.  Choose "Yes".

    Continue with install:

The bug is back -- the desktop crashes within an hour when playing YouTube videos -- and the Dell Latitude E6520 laptop is on Craig's List. So far, one scammer and two low-ballers.


- it's not as
straightforward as the standard install but there's a couple of steps
that will make it work. The main trick is to make sure that nvidia drivers
are never loaded until the point at which you've got everythng else
configured.


If you have a URL with detailed instructions of how to install Buster on a laptop with Optimus, you have a laptop with Optimus, you followed the instructions, and the laptop can play YouTube videos for 24 hours without crashing, please post the URL.
