Dual install MX18 and PopOS on System76 Oryx-Pro

#1

Post by curtvaughan » Thu Dec 20, 2018 12:35 pm

I recently purchased a System76 Oryx-Pro laptop. I resized and repartitioned the PopOS preinstalled system to allow for multiple OS boots. The complication is that PopOS is configured with systemd-boot, whereas toward the end of the MX18 installation, the installer wants to install GRUB. I'm afraid that if I let it configure and install GRUB that it will make my already installed PopOS installation non-bootable, so I disallowed the GRUB install. The net result is that on reboot, the systemd boot loader only sees PopOS. I guess I have two questions (this isn't specifically with MX, as I am sure I'll have similar issues with other GRUB defaulted installations):

1) How can I get the systemd boot loader to see the MX partition (or is that possible)?

or, alternatively,

2) If I let the MX installer install GRUB, will GRUB be able to detect PopOS as well as MX?

I don't particularly care which boot loader I use, though this is my first experience with systemd boot loader. If allowing MX to install GRUB will allow a successful dual/multi-boot I'd be happy with it.

Thanks for any suggestions. I have also sent out a query to the System76 folks about this, but still haven't heard back.

My understanding is that this will update the systemd bootloader

Code: Select all

bootctl update
do this from your popOS install.

I think you could also install grub through our installer, and if you wanted, go back to systemd boot by using your system's UEFI/bios utility to choose the popOS efi as teh default boot. Our efi shouldn't over write anyone else's.

I don't have any actual experience with systemd boot or popOS though so take my advice with a grain of salt.

It seems that it might be tricky to get it really working well with any other Linux than PoPOS, though maybe we can port over those GPU switcher applets from their PPA.

Thanks for all of your input. It turns out that allowing the MX installer to install GRUB worked, and I'm able to boot both MX and PopOS. I want to experiment/investigate Dolphin_Oracle's suggestion in executing "bootctl update" from the PopOS installation, just to see how that works with the systemd-boot.

Not directly related to this, but in alignment with the way the Oryx-Pro issues arise with various distributions, Arch based distros - in my case, ArcoLinux - have problems booting the Live USB for installation, running into issues with the kernel attempting to load NVIDIA drivers during the boot process, rather than having that being processed by X after boot time. It is suggested by a PopOS dev that introducing a "nomodeset" parameter into the kernel at boot may fix that issue - I still need to try it. The MX18 Live USB had no issue with that, though after installation, I still can't get MX to work correctly in using the NVIDIA card onboard (GTX 1060) - the screen just goes blank after boot with a blinking cursor. I understand that the latest MX18 release has some issues with NVIDIA drivers that dev's are aware of, but just an f.y.i. That is a bit of a separate issue from the systemd-boot vs. GRUB.

BTW, I'm well aware of the philosophical issues with systemd, as per mentioned by asqwerth, but for better or worse it is a thing to be dealt with these days. If I can get GRUB to boot up my needed systems on the Oryx-Pro, I'm just as happy with that; if I can also figure out how to get multiboot working well with systemd-boot, all the better. Thanks again for all of your input! I'll post as things progress. I really appreciate MX as being a reliable, interesting Debian based desktop system - my favorite desktop with a Debian flavor (which is why I want it on my newest laptop). I've been using it for over a year now on my 2-year old HP Omen laptop with great success.

Bring up MX Tools and then run the "Nvidia driver installer"...then reboot and that should do it.

Does the Oryx use Optimus, or does it require those PopOS applets to switch the GPUs? The output of "System Information" would help.

It turns out we needed to also install virtualgl (plus virtualgl-libs:i386 for 64-bit) to get Bumblebee working on several test laptops, so the Nvidia Installer has been updated to add those.

There's been a request to also port over "nvidia-prime" from Ubuntu, but I think you need to boot with systemd to have that work.

@stevo, The Oryx uses its power management utility "system76-power" to switch between Intel and NVIDIA GPUs. It is accessible by either the command line or graphically via Power Management pull down menu (battery icon accessible via top right pull down icon):

This appears to be a diversion/addition to the original Ubuntu base.

Paul: Will try out your MX Tools suggestion later today. Thanks.
