Installation

Basic Input

  • Keyboard - works
  • External USB mouse - works (notification pops up asking to connect to dom0)
  • External USB keyboard - works (connect to a VM via sys-usb tray icon)
  • Touch-pad - works
  • Touch-pad supports “tap as click” and scrolling with 2 fingers works - 2 finger scrolling works, tap as click untested
  • Display brightness change shortcuts - works
  • Sound volume shortcuts - works
  • Keyboard led and keyboard brightness change shortcuts - n/a; no backlight
  • Output of xinput --list from terminal of dom0 - bash: xinput: command not found
  • Check if keyboard and/or touchpad is PS/2 connected (how to check ) - keyboard works when sys-usb is powered off

Internet and bluetooth

  • Ethernet cable connection - works out of the box or actions were required? - works
  • Ethernet cable connection - speed - 15MB/s download, 5MB/s upload; did not benchmark on local network
  • Wifi connection - works out of the box or actions were required? - works
  • Wifi connection - speed, is reliable over the time? - seems reliable over time; 14MB/s download, 5MB/s upload; did not benchmark on local network
  • Bluetooth - works out of the box or actions were required? - works
  • Bluetooth - shows devices, connection process works, sound output or copying works. - works; can play audio from phone via Qubes speakers, but the quality was poor (laggy)

Suspend

  • Suspend/Resume works - works out of the box or actions were required? - works
  • Does resume breaks WiFi, if it does, how to recover it? - additional steps required: reload the mt7921e kernel module (this can be done automatically)
  • Does resume breaks Bluetooth, if it does, how to recover it? - faulty; reboot whole system (I have not attempted reloading a module yet)

There’s probably a better way to fix both.

Video [increase VCPU to the qube before test]

  • Fullscreen and windowed video playback of youtube - 720p/1080p/2K/4K in Firefox. Does it drop frames? - faulty? this played fine immediately after install, but after updating, it will only play for a split second in fullscreen and windowed mode
  • Video file playback of file using mpv/mplayer/smplayer - 1080p? Higher resolutions and bitrates? - mpv works; after seeking or pausing it will often fail to resume immediately (see output below), switching to Debian and running sudo apt install pulseaudio-qubes worked wonderfully
  • Multiple displays configuration works (using available DP/Thunderbolt, HDMI or other video ports) - USB-C untested. 4K display over HDMI worked after increasing VRAM.

Audio

  • Speakers (sound playback) (was sys-audio used?) - works; sys-audio was not used
  • Head-phones via 3.5" jack - works, automatically turns off speakers
  • Head-phones via USB-C - works, automatically turns off speakers (note that you connect this directly to the desired VM)
  • Sound output via HDMI - worked originally but broke some time later
  • Audio-optical (S/PDIF) output - n/a

Fans

  • Fans are silent on idle - works
  • Are fans noisier than on Windows/Linux?. If they are, was thankfan or similar software tried? - untested

Other

  • Have you tried running Windows 10 HVM qubes? - untested
  • Does CPU boost seem to be working properly? - works; ran while :; do :; done which increased CPU frequency in xenpm start 1 | grep "Avg"

Specs:

  • ThinkPad L14 Gen 3 (AMD) spec sheet
  • Display native resolution: 1920x1080
  • Maximum possible RAM memory - 64GB
  • CPU score: 16282
  • 5 USB buses (lsusb output below):
    1. QEMU tablet
    2. Bluetooth, left USB-A, left USB-C (not the one for charging)
    3. unknown
    4. camera, right USB-A, left USB-C for charging and data
    5. unknown
  • Internal TPM - 2.0, untested because I’m awaiting AMD support for verified boot; I disabled TPM before installing
