Razer Blade Stealth Linux & Ubuntu 21.04

Razer Blade Stealth (Early 2016, Intel 6500U, UHD / HiDPI) Ubuntu Linux 20.10, running Wayland & Gnome.

Issues

Caps-Lock Crash

The RBS crashes randomly mostly if you hit "Caps Lock", causes by the build-in driver.

Modify /etc/default/keyboard, replacing capslocks by a second ctrl:

sudo nano /etc/default/keyboard
XKBOPTIONS="ctrl:nocaps"

Tweaks

Install Gnome Tweak Tool:

sudo apt install gnome-tweak-tool

"Capitaine" Cursors

mv capitaine-cursors-light ~/.icons/
  • Select via gnome-tweaks-tool: Appearance, Themes, Cursor
  • change cursor size
gsettings set org.gnome.desktop.interface cursor-size 32

Grub Theme

Razer Grub Theme for RBS 4k.

sudo mkdir /boot/grub/themes
sudo cp -r themes/grub /boot/grub/themes/razer

Add Theme:

sudo nano /etc/default/grub
GRUB_GFXMODE="3840x2160-32"
GRUB_THEME="/boot/grub/themes/razer/theme.txt"

Update Grub

sudo update-grub

Razer Core

Thunderbolt

  • Connect Razer Core
  • Authorization: Settings -> Devices -> Thunderbolt
  • Razer Core: Authorized

Note: This 2m cable works without problems. I measured no (performance) differences compared with the included very short cable (tested on Windows & Linux).

Nvidia Driver

Install nvidia-driver-390 driver:

sudo apt install nvidia-driver-390

Bumblebee

Install Bumblebee / Primus:

sudo apt-get install bumblebee bumblebee-nvidia primus linux-headers-generic socat mesa-utils

Change bumblebee.conf

sudo nano /etc/bumblebee/bumblebee.conf
LibraryPath=/usr/lib/x86_64-linux-gnu:/usr/lib/i386-linux-gnu
XorgModulePath=/usr/lib/x86_64-linux-gnu/nvidia/xorg,/usr/lib/xorg/modules,/usr/lib/xorg/modules/input

Change /etc/environment

sudo nano /etc/environment
__GLVND_DISALLOW_PATCHING=1

Create Nvidia Blacklist:

sudo nano /etc/modprobe.d/blacklist-nvidia.conf
blacklist nvidia
blacklist nvidia-drm
blacklist nvidia-modeset

Patch primusrun

sudo mv /usr/bin/primusrun /usr/bin/primusrun.bak
sudo cp usr/bin/primusrun /usr/bin/

primusrun glxinfo | grep OpenGL

Vulkan drivers

Install vkrun from the package primus_vk is as drop-in replacement for primusrun that enables to run Vulkan-based applications.

sudo apt-get install vulkan-tools primus-vk primus-vk-nvidia
