Post-installation setup

This document contains extra steps to perform after installing Dasharo in order to enable full functionality of your device.

Linux

This section covers Linux post-install steps tested on Ubuntu 22.04. It is likely thas similar procedures would for others Linux distributions as well.

Touchpad hotkey enablement

The touchpad hotkey needs extra setup to function correctly under Linux. To enable the touchpad hotkey to work under Linux, follow the steps below:

  1. Execute fixup script:
curl -sSf https://raw.githubusercontent.com/Dasharo/dasharo-tools/main/clevo/touchpad-fixup | sudo sh

After executing these steps, it should be possible to enable and disable the touchpad using the touchpad hotkey (Fn+F1) on the keyboard when using GNOME.

Touchpad multi-touch support

On NS7x an additional fix is necessary to enable multi-touch on Linux. Create a file /etc/modprobe.d/blacklist-psmouse.conf with the following contents:

blacklist psmouse

and then run the following commands:

sudo depmod -a
sudo update-initramfs -u

Updated kernel

On Gen 12 (Alder Lake), it's recommended to install the ubuntu-oem kernel which is a newer version than the default Ubuntu kernel. This version contains additional fixes for newer hardware which helps with power management and suspend on Gen 12 laptops. To install the ubuntu-oem kernel, run the following command:

sudo apt install linux-oem-22.04a

and reboot to use the new kernel.

Nvidia drivers

It is only necessary to follow this step if your device has Nvidia GPU

For proper working of the sleep mode on Ubuntu 22.04, it is required to install additional Nvidia drivers.

  1. Install drivers by executing the following command in the terminal:

    sudo apt install nvidia-driver-535 nvidia-dkms-535

  2. Reboot the device to apply changes by executing the following command in the terminal:

    sudo reboot

  3. (Optional) For power saving while the card is not in use, enable On-Demand mode in NVIDIA Control Panel:

  1. If for some reason dynamic power management for the GPU is not working (causing high power draw, poor sleep time or high temperatures), you may need to run this command, and then reboot the laptop:

    echo options nvidia "NVreg_DynamicPowerManagement=0x02" | sudo tee /etc/modprobe.d/nvidia_rtd3.conf

Suspend fix for SATA disks

Only affects laptops with M.2 SATA disks experiencing sleep issues (the power LED not blinking while the laptop is suspended)

Windows and certain Linux distros such as Ubuntu do not enable the necessary power saving tweaks to enable sleep mode while a SATA disk is installed.

  1. Execute fixup script:

    curl -sSf https://raw.githubusercontent.com/Dasharo/dasharo-tools/main/clevo/sata-suspend-fixup | sudo sh

Headset jack fix for NV4x 12th Gen

The headset jack in NV4x 12th Gen (Alder Lake) needs a fix that is available starting with kernel version v6.0 (patch be561ffad708f0cee18aee4231f80ffafaf7a419). If you are using an older kernel, you need to add the fix manually:

  1. Execute fixup script:

    curl -sSf https://raw.githubusercontent.com/Dasharo/dasharo-tools/main/clevo/nv4x-audio-fixup | sudo sh

  2. Reboot. The audio jack will now work correctly.

Windows 11

Updates and drivers installation

Several features on Windows 11 (i. e. suspending the device) may not work or work unexpectedly without installing all of the updates and drivers.

To install all of them, log into the system, connect the device to the mains and Internet, then follow the steps below:

  1. Press the Windows button on the keypad.
  2. Type Windows Update Settings in the search and press Enter.
  3. Select the Check for updates bar to start installing available updates and drivers. During this process previously selected bar might be changed to Restart now or Retry, so click them if something hasn't been installed yet, something has gone wrong or a restart is just required. The entire process may take up to 30 minutes.
  4. Select the Advanced options option in the Windows Update Settings window.
  5. Locate the Optional updates option and click on it.
  6. Select all displayed updates and drivers.
  7. Select the Download & Install bar to start installing additional updates and drivers. During this process previously selected bar might be changed to Restart now or Retry, so click them if something hasn't been installed yet, something has gone wrong or a restart is just required. The entire process may take up to 30 minutes.
  8. Repeat all steps until all updates have been installed.

Suspend fix for SATA disks

Only affects laptops with M.2 SATA disks experiencing sleep issues (the power LED not blinking while the laptop is suspended)

Windows and certain Linux distros such as Ubuntu do not enable the necessary power saving tweaks to enable sleep mode while a SATA disk is installed.

  1. Download the script: link
  2. Double click on the script to install the tweak

Unrecognized USB Controller device in device manager

Windows Update may sometimes fail to automatically install drivers for the Thunderbolt DMA controller device. The driver may be installed manually from the Windows Update Catalog:

  1. Download the update cabinet: Windows Update link
  2. Right-click on the cabinet and select Install to install the driver

After the update, Thunderbolt Control Center will become available and the warning in device manager will disappear.
