Hi Nadzeya,
Thank you for the follow-up. Here are the technical details from my
system (Alienware m18 R2 with Intel 14th Gen) to help with the
investigation.
1. System Context:
Kernel: 6.11.0-28-generic (HWE stack)
Hardware: Intel Core 14th Gen (i9-14900)
2. Package Policies:
Plaintext
libva2:
Installed: 2.20.0-2ubuntu0.1
Candidate: 2.20.0-2ubuntu0.1
Version table:
*** 2.20.0-2ubuntu0.1 500
500 http://archive.ubuntu.com/ubuntu noble-updates/universe amd64 Packages
100 /var/lib/dpkg/status
intel-media-va-driver:
Candidate: 24.1.0+dfsg1-1ubuntu0.1
Version table:
24.1.0+dfsg1-1ubuntu0.1 500
500 http://archive.ubuntu.com/ubuntu noble-updates/universe amd64 Packages
3. Issue Confirmation (Reproducibility):
When using the stable version of the Mesa/VA stack on Noble (without the
mesa-2404 candidate snap), the issue is clearly reproducible.
Detection failure: My application fails to detect VA-API hardware
acceleration entirely.
Relocation Error: During my previous tests with a non-patched environment,
the application crashed with:
symbol lookup error: /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so:
undefined symbol: vaMapBuffer2
This confirms that the Intel iHD driver (v24.1.0) expects a symbol that
is not present in libva2 (v2.20.0).
4. Full vainfo output (Stock archive):

As a reminder, the issue disappears immediately when switching to the
mesa-2404 (candidate) snap, which seems to contain the necessary glue to
avoid this relocation error on 14th Gen hardware.
