Running the latest X-Plane for Linux on my MSI GP65 Leopard 9SD works like a charm, and gives at least the same frame rate as under Windows 10. With real weather setting (stormy day), max number of world details, antialiasing and scenery shadows drawn, I still get 70+fps on KDE Neon 20.04.

My laptop:

CPU Intel Core i7-9750H
GPU NVIDIA GeForce GTX 1660 Ti
UHD Graphics 630 (Mobile), Intel
RAM (Memory) 16 GB RAM
Screen Size 15.6 inches (39 centimeters)
Screen Resolution 1920 x 1080 pixels (1080p FHD)
Refresh Rate 144 Hz

I’m running X-plane under KDE Neon 20.04, using drivers from Ubuntu, installed with «ubuntu-drivers autoinstall», giving me version 440.100.

I forced the Nvidia card to max performance using the Nvidia X Server Settings controller, plus «sudo cpufreq-set -r -g performance» to ensure max CPU speed. I was afraid that this would make the fans blow all the time, but they only make noise as long as X-Plane is running. As soon as the simulator is stopped they go silent again. As long as I’m connected to external power I just leave it like this, and as soon as I’m on battery I simply reduce power drainage with «sudo cpufreq-set -r -g powersave».

All in all I’m impressed with what the Ubuntu 20.04 based KDE Neon could do with X-Plane, compared to the fact that I tried it with Windows 10 installed a bit earlier. Roughly the same frame rate, but then W10 had the latest Nvidia Game Ready drivers for the MSI laptop.

I’ve also tested X-Plane under Manjaro Plasma, Manjaro Gnome, Arcolinux and OpenSuse Tumbleweed and they all manage about 20 fps only. On all those distros I used the distro delivered Nvidia drivers and max performance on the GPU and CPU like on KDE Neon. I’ve not been able to find out what Ubuntu has done differently when it comes to the NVidia part, but I can see that the Ubuntu Nvidia contoller is more detailed and allows more tweak than the one supplied with the other distros. However, I only changed to max performance. No other tweaks.

I’ve recently learnt that Laminar Research, the maker of X-Plane is doing their Linux work on Ubuntu.

Update August 18th 2020:
I do get the same frame rates even if I leave Nvidia settings i to «Auto», so obviously the Nvidia controllers are doing their job ok.

MSI GP65 Leopard 9SD and Manjaro 20.01

This is just a short note to let you know that the

MSI GP65 Leopard 15,6″ Full HD 144Hz
GeForce GTX1660Ti 6GB,Core i7-9750H,16GB RAM,512GB PCIe SSD

works like a charm with Manjaro 20.01 – through installation and final boot into a running system. The only thing I needed to do was disabling Secure Boot in the BIOS. No other changes to the BIOS or Linux kernel boot parameters are necessary. Even adding the «nomodeset» parameter before booting is unnecessary. It’s all well handled by the default Manjaro boot parameters in the install image.

After installation of Manjaro 20.01

During installation I selected non-free drivers to go with the Nvidia card, and that selection was kept also after the initial reboot.

The steelseries keyboard backlight can still be changed, mostly like you can on Windows 10 (preinstalled OS, removed completely when installing Manjaro!), but it has to be done from the command line through the program below:

  1. Configuration tool for SteelSeries per-key RGB keyboards on MSI laptops:
  1. «msi-perkeygb –model GS65 -s 23c2ba» gives you keys with the Manjaro greenish color.
  2. «msi-perkeyrgb –model GS65 -p aqua» gives you wandering/changing colors.

The program has some builtin identifiers, and the GP65 is not one of them for the moment.Therefor you have to use GS65 as an identifier:

Available presets for GP65 (tested by me):
– aqua
– chakra
– default
– disco
– drain
– freeway
– rainbow-split
– roulette

The laptop i rock solid in stability with the Manjaro distro installed. Wifi, speakers, micophone, webcam… it all works perfectly. Tested with Skype too. I do not use hibernation, but suspend is flawless. Resume from suspend is equally flawless. Wifi reconnects immediately.

When it comes to battery time… Before installing and enabling TLP is was short. Maybe ~90 mins. However with TLP the GP65 both cooled down and the battery time stretched to acceptable levels.

So, in short: A perfect match!! (in my mind at least….)
