I’m running CasaOS on Ubuntu 26.04 LTS on host DXP2800.
Hardware
CPU: 4× Intel N100
iGPU: Intel Alder Lake-N [UHD Graphics]
NIC: Intel I226-V
Storage: NVMe + HDDs (not relevant)
Problem In the CasaOS UI GPU/APU/IGPU monitoring section, the system:
fails to detect the iGPU correctly (no expected metrics),
shows errors / missing temperature and utilization readings (and fan-related data if applicable),
behaves differently than my setup in ZimaOS, where the iGPU is detected and metrics are available.
Hypothesis This looks like an issue in the detection/metrics pipeline (for example, the monitoring logic may rely on a “PCI VGA” classification path, while this platform exposes the device differently as a “Display controller”). It may also be related to container access to DRM devices (e.g., missing /dev/dri / missing required mounts).
Steps to reproduce
Install Ubuntu 26.04 LTS
Install CasaOS on the host
Enable GPU/APU/IGPU monitoring in the CasaOS UI
Observe detection result and metrics charts
Compare with ZimaOS (where metrics appear)
Expected behavior CASAOS should detect Intel Alder Lake-N iGPU (UHD Graphics) and display standard GPU metrics (utilization / temperature, etc.).
Actual behavior CASAOS monitoring does not detect the iGPU properly and does not provide the expected metrics.
Diagnostics (please add these outputs)
lspci -nnk | grep -A3 -i "vga|display|graphics"
ls -l /dev/dri
lsmod | grep -E "i915|intel"
uname -a
docker version and docker info
CASAOS UI logs / monitoring module logs (exact error text + timestamps)
(Optional) relevant part of docker-compose.yml used for the monitoring container, without secrets
Attachments Please include screenshots/log snippets from the UI showing the error and the missing metrics.
