LUKS Discard

By default, Qubes does not use discard with a LUKS volume. To enable discard, run:

sudo cryptsetup --allow-discards --persistent refresh LUKS-UUID-HERE

S0ix sleep

On certain hardware like the Thinkpad T14 Gen 1, you need to enable S0ix sleep support for suspension to work correctly. Use the following command:

sudo qvm-features dom0 suspend-s0ix 1

Default appmenu

The default apps to show on AppVMs' menu when created can be configured with qvm-features.

Example:

sudo qvm-features fedora-41 default-menu-items 'org.gnome.Nautilus.desktop org.gnome.Ptyxis.desktop'
sudo qvm-features fedora-41 netvm-menu-items 'org.gnome.Ptyxis.desktop'

sudo qvm-features debian-12 default-menu-items 'org.gnome.Console.desktop org.gnome.Nautilus.desktop'
sudo qvm-features debian-12 netvm-menu-items 'org.gnome.Console.desktop'

Lenovo ePrivacy

Lenovo ePrivacy can be controlled through /proc/acpi/ibm/lcdshadow. I use the following shortcuts:

• F5: sudo bash -c 'echo 1 > /proc/acpi/ibm/lcdshadow'
• F6: sudo bash -c 'echo 0 > /proc/acpi/ibm/lcdshadow'

Bitwarden & Element Flatpak

These apps require the keyring to be created first to work properly. Simply open a browser like Microsoft Edge and set an empty password for the keyring before using them.

Video player

In my experience, VLC works best. Changing video output to X11 video output (XCB) reduces CPU usage by 10% on my Thinkpad P53. See this link.

If you want to use MPV, make sure that --vo=x11 --profile=sw-fast is passed as arguments. See this link.
