Razer Blade Stealth Compatibility

As a Razer Blade Stealth owner, since Stealths have a few known issues with their Linux compatibility here is a good place to start for work-arounds and temporary fixes :

Roland Guelle GitHub

In this page I listed all the fixes and workarounds I had to implement to get a working version of Linux Mint 19.1 on my RBS. It was not very difficult and not a frustrating experience at all.

I have not encountered all the bugs listed in Roland Guelle's GitHub so I have not yet applied all the fixes he proposes. Some of them were of assistance though.

My Stealth Model is a RZ09-0239

Following Roland Guelle's instructions, the first things I did before attempting to install Linux in dual boot were :

• Run all Windows 10 updates.
• Check for INTEL-SA-00086 Intel Management Engine Critical Firmware Vulnerability (my Stealth passed the test successfully and was not vulnerable)
• Clean up and free space using Windows utility (Start > cleanmgr (Run as Administrator))
• Clean using Bleach Bit
• I did not use Windows to resize the disk as Roland did. Instead, I ran a live session of GParted to resize the Windows partition to smaller than Windows 10 would allow (465GB > 120GB)
• I ran a live session of Linux Mint 19 (linux kernel 4.15.0-20) and used the installer. Contrary to previous versions of Ubuntu installers it did not end with segfaults as Roland's did and the installation was correct.
• Be mindful that the disk tag is not a classic /dev/sdx# but something more fancy like /dev/nvme0n1p#
• The dual boot did not break Windows boot and Grub was installed correctly.

• Setup timeshift to make system snapshots daily, weekly, monthly and at boot
• Update intel microcode as advised by Roland (and reboot)
• Update the system

Key rule in systems : if it works, don't break it

Apparently this issue was encountered on some laptops running different versions of Ubuntu from 16.04 upwards.

This fix uses pm-utils which is usually installed on fresh installs of mainstream distributions. We backup the configuration file we will tweak just in case.

sudo apt-get install pm-utils
sudo cp /etc/systemd/logind.conf /etc/systemd/logind.conf.bak
sudo gedit /etc/systemd/logind.conf

Uncomment the following lines and change the values accordingly :

HandleSuspendKey=suspend
HandleLidSwitch=suspend
HandleLidSwitchDocked=suspend
LidSwitchIgnoreInhibited=yes

Edit the Grub conf file and add this value :

sudo gedit /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="button.lid_init_state=open"

More info on button.lid_init_state

The screen flickering issue causes the screen to flicker to black for an instant. You can check this by running :

dmesg | grep 'ERROR'

You have the issue if you see one or more lines like theese

[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun

A work-around to this issue is adding the following parameter to the kernel :

intel_idle.max_cstate=4

To make the change apply on every boot add it in the file

/etc/default/grub

at the following line :

GRUB_CMDLINE_LINUX_DEFAULT="intel_idle.max_cstate=4"

Run :

sudo update-grub

and reboot to apply.

You can check which parameters were passed to kernel at boot by running :

cat /proc/cmdline

Screen seems to randomly go black on external monitor.

GitHub thread on the subject

Setting the sound output to “HDMI / DisplayPort - Built in Audio” seems to fix the issue.

Another workaround if the previous option is not available could be to plug an audio output to the 3.5 jack → This needs to be validated by experience (23/06/19)

• Remove media OSD in Cinammon > System Settings > Notifications
• Switch Background to full black
• Careful, switching workspaces causes little stutters on the external monitor
• Some unidentified manipulations can cause the terminal running mplayer to have a CTRL-lock even with the CTRL unpressed. This locks you out of mplayer → Investigate

This requires to be using libinput instead of synaptics. You can check this by running these commands using the proper device ID.

xinput list
xinput list-props <DEVICE-ID>

Install the following packets :

sudo apt install xdotool wmctrl libinput tools
git clone http://github.com/bulletmark/libinput-gestures
cd libinput-gestures
sudo ./libinput-gestures-setup install

Add your user to 'input' group and log out/log in to validate the change :

sudo gpasswd -a $USER input

To start the process, or restart it :

libinput-gestures-setup start|stop|restart|autostart|autostop

Note : the autostart/autostop will enable the app to start/stop automatically on login

The configuration file is located at /etc/libinput-gestures.conf and a user-specific one can be created at ~/.config/libinput-gestures.conf

Horizontal scrolling is deactivated on the touchpad by default. You can check this by running

xinput list

A list will appear looking like this

My touchpad id is 15. You can list the device properties by running

xinput list-props 15

Change the following line from 0 to 1

libinput Horizontal Scroll Enabled (284):	0

By running :

xinput set-prop 15 284 1

Change your device ID and libinput property if required (respectively 15 and 284 here).

To render this change permanent at every boot, add this command at startup :

xinput set-prop "1A586757:00 06CB:8323 Touchpad" "libinput Horizontal Scroll Enabled" 1

Device IDs and libinput property numbers may vary so it's best to use the full identifiers in this case.

There might be a way to edit the config file located at /usr/share/X11/xorg.conf.d/40-libinput.conf and adding something but I haven't been able to make it work that way yet.

Updated procedure for Linux Mint 22 and eGPU running Nvidia GTX 1060 6GB

Thunderbolt (TB3/TB4) is explicitly designed for hot-plugging.

It uses :

• Hot-plug–safe PCIe tunneling
• Overcurrent protection
• Digital handshaking before enabling high-power lanes
• Cable and device negotiation before link-up
• Mandatory protective circuitry required by Intel’s TB certification

You are supposed to plug and unplug TB devices while the system is powered — that’s how eGPUs, docks, displays, and drives are meant to work.

There is no scenario in which hot-plugging a functioning Thunderbolt cable damages the hardware.

- Power on laptop normally
- Log into desktop
- Turn ON the eGPU enclosure
- Wait 2–3 seconds (GPU initializes)
- Plug in the Thunderbolt cable
- Wait for the OS to detect/authorize the eGPU

- Close any apps using the eGPU (optional but safer)
- Save your work
- Unplug the Thunderbolt cable
- Wait 2–3 seconds
- Power OFF the eGPU enclosure if desired

sudo apt install bolt thunderbolt-tools

Ensure the bolt service is running:

systemctl status bolt

lspci | grep -i thunderbolt
lsmod | grep thunderbolt

Expected:

• Intel Thunderbolt controller listed
• thunderbolt kernel module loaded

In BIOS:

• Thunderbolt: Enabled
• Security Level: No Security (SL0)

⚠️ Required, otherwise devices may not enumerate under Linux.

Boot the laptop without the eGPU connected.

Then:

• Power ON the Core X
• Plug the Thunderbolt cable

Check detection:

boltctl list

If needed:

sudo boltctl authorize <UUID>

Verify PCIe device:

lspci | grep -i nvidia

Install the recommended driver (for GTX 1060):

sudo apt install nvidia-driver-535

⚠️ Do NOT use NVIDIA .run installer (breaks package management and updates)

echo "blacklist nouveau" | sudo tee /etc/modprobe.d/blacklist-nouveau.conf
echo "options nouveau modeset=0" | sudo tee -a /etc/modprobe.d/blacklist-nouveau.conf
sudo update-initramfs -u

Reboot (without eGPU connected).

Linux Mint 22 does not provide prime-run by default.

Create it manually:

sudo nano /usr/local/bin/prime-run

Content:

#!/bin/sh
__NV_PRIME_RENDER_OFFLOAD=1 \
__GLX_VENDOR_LIBRARY_NAME=nvidia \
__VK_LAYER_NV_optimus=NVIDIA_only \
__NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 \
exec "$@"

Make executable:

sudo chmod +x /usr/local/bin/prime-run

Connect the eGPU after boot, then run:

nvidia-smi

You should see the GTX 1060 listed.

Test offloading:

prime-run glxinfo | grep "OpenGL renderer"

Run applications on the eGPU:

prime-run <application>

Example:

prime-run blender
prime-run steam

• Laptop must boot without eGPU connected (known limitation on this hardware)
• eGPU must be hot-plugged after login
• Internal display introduces a ~20–30% performance penalty (PCIe copy-back)
• External monitor connected to the GPU removes this penalty completely
• Cycles rendering (Blender) is not affected by this limitation
