Suspend

  • Suspend/Resume works - works out of the box or actions were required? - works, set sleep mode to Linux S3 in bios.
  • Does resume breaks WiFi, if it does, how to recover it? - with default fedora-39-xfce template reloading kernel module is necessary, however this seems a template issue instead of a hardware compabitility issue, with fedora-39 template resume does NOT break WiFi.

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? - can play 4K without dropping frames when the youtube viewport is small, however the bigger you make the viewport the more frames it starts to drop. 4K fullscreen on a 4K monitor drops quite a lot of frames. I think I read somewhere this was a problem inherent to Qubes.
  • Video file playback of file using mpv/mplayer/smplayer - untested
  • Multiple displays configuration works (using available DP/Thunderbolt, HDMI or other video ports) - 4K external monitor over HDMI works fine. USB-C untested.

  • Head-phones via 3.5" jack - works, automatically turns off speakers

  • 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? - Yes, works fine, including connecting USB block devices and audio inside Windows qube.
  • Does CPU boost seem to be working properly? - Yes
