Bug ID: 291804
Summary: ASUS Zenbook 14 OLED UX3405MA (Meteor Lake) lacks GPU
acceleration on FreeBSD 15.0 Intel Meteor Lake Xe
graphics unsupported on ASUS Zenbook 14 OLED UX3405MA
(FreeBSD 15.0) No hardware graphics acceleration for
Meteor Lake GPU on ASUS Zenbook 14 OLED UX
Product: Base System
Version: 15.0-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
Environment:
- FreeBSD 15.0-RELEASE (memstick image, booted on bare metal)
- Laptop: ASUS Zenbook 14 OLED UX3405MA
- CPU: Intel Core Ultra (Meteor Lake)
- GPU: Integrated Intel Meteor Lake Xe graphics
- Display: 14" OLED internal panel
Problem:
FreeBSD 15.0 does not provide hardware graphics acceleration on this laptop.
The integrated Intel Meteor Lake GPU is detected but no DRM/i915 driver binds,
resulting in software rendering (llvmpipe) and basic framebuffer-only display.
Steps to reproduce:
1. Boot FreeBSD 15.0-RELEASE from USB on ASUS Zenbook 14 OLED UX3405MA.
2. Start a graphical session (Xorg or Wayland) or inspect GPU driver state.
3. Observe that hardware acceleration is unavailable and the display operates
in framebuffer mode.
Expected result:
Intel integrated GPU should initialize with DRM/i915 (or appropriate Meteor
Lake support), providing modesetting and hardware acceleration for
Xorg/Wayland.
Actual result:
- No i915/DRM driver binds to the Intel Meteor Lake GPU.
- Graphics fall back to software rendering (llvmpipe).
- Xorg logs indicate no usable hardware acceleration; modesetting limited.
- System remains usable only with basic framebuffer output.
Diagnostics attached:
- dmesg.txt (kernel messages showing GPU detection and driver status)
- pciconf.txt (PCI device listing; includes Meteor Lake GPU IDs)
- Xorg.0.log (driver fallback details)
- kldstat.txt (loaded kernel modules)
Notes:
- The same hardware provides full GPU acceleration under Linux (Void Linux,
kernel 6.x), suggesting missing/incomplete Meteor Lake DRM support in FreeBSD
15.0.
- No custom kernel parameters were used; this is a stock 15.0-RELEASE live
environment.
