  • Nouveau, libgallium?

    From Boyan Penkov@3:633/10 to All on Tuesday, June 30, 2026 21:20:01
    Hello folks,

    I saw another issue that seems to point to mesa and nouveau, but this
    time with more specifics -- it seems libgallium was the one to
    actually segfault:

    Your VGA (Quadro K2200 is it?) is supported by proprietary Nvidia
    driver, so my suggestion is to install it from Debian repo and see if
    your stability issues go away.
    This way you will also check if VGA itself is working fine and doesn't
    have any hardware defects, which could be hidden and be the source of
    sporadic stability issues.

    Hello Alexander -- yes, fair point, and I don't know how
    unconventional my decision is here, but this card is getting
    increasingly old, barely supported by the official driver, and I don't
    want to have to mess with guessing which Nvidia driver update will
    finally fail to boot period (https://wiki.debian.org/NvidiaGraphicsDrivers#data-center-d13), so I
    am steering away from nvidia-driver.

    So my guiding light here is for this machine, forget the proprietary
    driver and use the FOSS one, but this seems to have shot me in the
    foot...

    Cheers!

    It is either supported or not. It looks like [1] the version 580.xx will
    be the final version for your VGA.
    Version 550.xx, which is available for Debian stable [2], supports it.
    If you are on Trixie and use kernel version 6.12, then nvidia-driver

    If something will happen with the new 6.12.xx kernel update and
    nvidia-driver DKMS module would fail to compile, you will know about it
    from the console output.
    Even if you ignore the errors and reboot to the black screen on tty7,
    you will still have access to tty1 (Ctrl+Alt+F1) console and the way to
    sort it out.

    The choice is yours of course, but getting a stable and performant
    system for at least two years, until the next Debian stable release,
    seems like a no-brainer to me.

    Hey Didier,

    No, you're absolutely right, I pulled this in from testing.

    The issue presents itself on both libgallium 25 from Trixie and
    libgallium 26 from testing.

    That's the thing -- I'm on stable-bpo, which has linux 7.0, and the
    module did not compile out of the gate for me when I tried the update.
    Either way, I'd rather anticipate the problem of getting off
    nvidia-driver now on this machine.

    Hello,

    didier@hp-notebook14:~$ apt-file search libgallium # (trixie+backports repositories here):
    mesa-libgallium: /usr/lib/x86_64-linux-gnu/libgallium-25.0.7-2+deb13u1.so mesa-libgallium: /usr/lib/x86_64-linux-gnu/libgallium-25.0.7-2.so mesa-libgallium: /usr/lib/x86_64-linux-gnu/libgallium-25.2.6-1~bpo13+1.so [...]

    I would suggest to investigate your apt sources because libgallium-26.1.2-1.so on your system does not seem to be present in trixie+backports repos...

    apt-policy mesa-libgallium should indicate where this package come from:

    didier@hp-notebook14:~$ LANG=en-US.UTF-8; apt policy mesa-libgallium mesa-libgallium:
    Installed: 25.0.7-2+deb13u1

    The issue presents itself on both libgallium 25 from Trixie and
    libgallium 26 from testing.

    Have you tried libgallium 25 from Trixie-backports? I have observed that sometimes when you use a backports kernel you need adequate backported libraries.
    From the modification journal of mesa-libgallium (trixie-backports):
    "[...]
    * Lower libdrm-dev to 2.4.124-1 to match the version in Trixie
    [...]"
    which suggests that mesa-libgallium from Testing is likely to create
    problems in Trixie.

    I would advise you against performing dist-upgrades of a stable Debian
    distro: dist-upgrades are meant only for major version upgrades, and
    even then, they are meant to take place only after an ordinary upgrade.

    Possibly you could also assert if you need at all backports and
    fasttrack repos for other purposes, because your hardware being not the
    latest (at least the graphic card), it does not seem to need that. And
    the reliablity of a Stable Debian is greater than that of a Stable+backports(+fasttrack) one
