Hellp, i’ve been using this laptop for a few months running Qubes OS, for whatever reason, after some recent updates, i believe something is wrong with my system, for some reason usual apps i run in dvm, standalone seem to lag allot more, same with audio through microphone of sys-usb, web browser, discord and such, i have no clue why, i my bios config is default for the most part and my cpu, ram are usually pretty low in terms of usage, i’ve tried switching between all 3 recent kernels as of recent, i don’t know what’s causing it, and i’m hoping you guys push an update to somehow get this resolved, when i use discord voice calls, and i join a call, i tend to lag allot, as in the qube it self slows down, and i have an audio play back device too in the discord qube, i notice my audio lagging as if it’s CPU related, though my CPU usage on average does not surpass 50 usage, i have about 10gb ram in that qube, on average 8gb is free, however it tends to slow down a lot making voice chatting unbearably annoying.

FYI, it used to work perfectly with absolutely 0 issues initially, and really good performance, until a bit later, i’m certain it’s related to more recent qubes update as i don’t thinker with Qubes dom0 nor the bios.

also, on 6.11.25-1.fc37 kernel my CUDA Nvidia 4060 8gb Vram works, however on the more recent kernels, not detected at all, i had to use this one, please fix thank you 77 and 35 i don’t remember which one sorry
maybe both im not home now i could not check.

also there is a bug where dom0 updater shows a blank page sometimes, until i reboot, happen sometimes pls fix it, also with libre wolf, if i open a youtube video and full screen, once i tab out, the entire browser breaks, and the windows glitch, visually they don’t update unless i re full screen the tab it self by dragging it to the corners of my screen, one way to solve this which is temporary is to move one of the tabs (decouple) from others that glitched with it due to the youtube tab, then merge all of them again into a single group, this happens almost all the time and has been the case on my other laptop which i used to use with qubes OS, i don’t know if this is Qubes or LW browser related, the qube is a debian qube.

another issue is that when the laptop suspends i lose internet connection, so it’s impossible to leave my laptop downloading something, i had to disable suspend in order to leave my network manager fully functional, i use mullvad vpn qube.

Can you describe exactly what you mean by “lag a lot more” ?

Hi, thank you for your post.

The device you have is the NVIDIA variant, which is not Qubes-certified. This means that we cannot give any official support for this laptop for Qubes OS.

However, we try to help where we can and I noted your WiFi problem, that can most likely be solved by increasing the memory for sys-net.

      Experiencing multiple compatibility issues with Qubes OS, likely kernel-related, affecting video playback, battery charging, USB functionality, and network switching. Details below.

Issues Encountered

I am running Qubes OS R4.2.4 on a NovaCustom V5xTNC_TND_TNE laptop with Dasharo (coreboot+UEFI) v0.9.1 firmware and an NVIDIA RTX 4060 GPU. This model is not Qubes-certified, and I am experiencing several issues that I believe are related to kernel or hardware compatibility rather than configuration. These issues appeared after recent Qubes updates and were not present initially. Below is a detailed list of the problems and my observations:

  1. Video Playback Lag:

    • YouTube videos are extremely laggy, even at 720p, regardless of resource allocation (e.g., increased RAM/CPU, disabling memory balancing) in AppVMs, DisposableVMs, or Whonix-based qubes.
    • In contrast, 1080p videos on some sites (e.g., Internet Archive) play without issues.
    • This affects browsers like LibreWolf and Firefox in Debian-based qubes.

  2. Battery Charging Issue:

    • The battery fails to charge above 40% after multiple reboots when using the latest kernel (likely 6.6.7-1.fc37, as mentioned; possibly a typo in my original post).
    • Switching to kernel 6.15.7-1.fc37 in dom0 resolves this issue.

  3. Network Switching Failure:

    • When using the latest kernel (6.6.7-1.fc37) in the sys-net qube, unplugging an Ethernet cable prevents the system from switching back to WiFi, even after a reboot.
    • Reverting to an older kernel (e.g., 6.15.7-1.fc37) fixes this issue.
    • I use a Mullvad VPN qube, and suspend/resume causes network drops, requiring me to disable suspend to maintain connectivity for downloads.

  4. USB Port Functionality:

    • Both USB ports detect devices (e.g., phones) for charging but fail to recognize them as storage devices for file transfers in sys-usb qubes.

  5. High System Temperatures:

    • The system runs abnormally hot, even when operating a single DisposableVM, despite low CPU usage (below 50%) and ample free RAM (e.g., 8GB free out of 10GB allocated in affected qubes).

  6. Additional Notes:

    • These issues were not present initially; performance was excellent until recent Qubes updates.
    • Testing on Ubuntu with the same hardware showed no such problems, suggesting Qubes-specific compatibility issues.
    • I have tried switching between recent kernels (e.g., 6.11.25-1.fc37, where NVIDIA CUDA is detected, vs. 6.15.7-1.fc37 or later, where it is not).
    • My BIOS configuration is mostly default, and CPU/RAM usage remains low during these issues.

Questions for the Community and @NovaCustom

  • Are these issues primarily due to kernel or firmware incompatibilities with the NVIDIA GPU variant, given this model lacks Qubes certification?
  • Would switching to open-source Nouveau drivers for the NVIDIA RTX 4060 resolve these issues, or are proprietary drivers necessary for stability?
  • Which kernel version is recommended for dom0 and sys-net/sys-usb to balance hardware support, stability, and NVIDIA functionality?
  • Should I consider switching to another OS (e.g., Ubuntu, which had no issues) to avoid these problems, or are there specific configurations/firmware updates I should try first?

I appreciate any guidance or recommendations, especially from users with similar hardware or NovaCustom support. If needed, I can provide logs (e.g., /var/log/xen/console/guest-* or dmesg) when I return to my system.

Or as a last resort, switch another OS?, which seems to solve all of my problems.

Hi, thank you for your post. I’m sorry for our late reply.

We are sorry to inform you that we cannot provide any support for the NVIDIA variants in combination with Qubes OS.
