Public bug reported:
Package:
nvidia-driver-535
System:
- Ubuntu 22.04 (jammy)
- Kernel: 6.8.0-100-generic
- NVIDIA driver: 535.288.01-0ubuntu0.22.04.1
- xserver-xorg-video-nvidia-535: 535.288.01-0ubuntu0.22.04.1
- gnome-shell: 42.9-0ubuntu2.3
- Chrome: 145.0.7632.109-1
- GPU: NVIDIA GeForce RTX 3090
- Session: GNOME on Xorg (not Wayland), fractional scaling enabled
Summary:
I have repeated hard freezes requiring forced reboot. Pattern is consistent:
Google Meet call under normal usage (multiple participants, active audio), then
full desktop freeze. In both incidents, logs show repeated nvidia-drm modeset
ownership errors plus heavy GNOME compositor allocation warnings and display
re-probe churn.
Incident windows:
- Thu 2026-02-19 (boot -5): freeze around 16:17 EST
- Mon 2026-02-23 (boot -1): freeze around 13:41 EST, reboot at 13:44 EST
Steps to reproduce (best-effort):
1. Boot kernel 6.8.0-100, log into GNOME Xorg.
2. Keep fractional scaling enabled:
- x11-randr-fractional-scaling
- scale-monitor-framebuffer
3. Use multiple displays (I have four, `xrandr | grep "current"` gives a
total resolution of 16128 x 4938).
4. Join Google Meet with active audio for an extended period.
5. Eventually desktop freezes hard and requires reboot.
Expected result:
System remains responsive.
Actual result:
Desktop hard-freezes. Input becomes unusable and I must hard reboot.
Key log evidence:
- NVIDIA DRM errors (both freeze boots):
- 2026-02-23T09:37:03 and 13:27:10:
[nvidia-drm] Failed to grab modeset ownership
- 2026-02-19T14:27:58:
[nvidia-drm] Failed to grab modeset ownership
- GNOME compositor warnings (both freeze boots):
- "Can't update stage views actor ... needs an allocation"
- Counts:
- Xorg/NVIDIA display churn:
- Repeated NVIDIA(GPU-0) monitor re-probe lines
- Counts:
- boot -1: 2809
- boot -5: 2145
- Chrome/WebRTC errors also present during incident windows:
- sdp_offer_answer.cc:500 codec-collision errors
- Counts:
- boot -1: 13
- boot -5: 4
Negative findings:
- No kernel panic/Oops/BUG/lockup/OOM signatures in incident boots.
- No NVRM Xid logged.
Additional context:
This started in close proximity to updates on 2026-02-18 (kernel 6.8.0-100
and NVIDIA 535 components updated). Not proof of causation, but timeline may be
relevant.
Request:
Please investigate possible regression/instability in nvidia-driver-535 +
nvidia-drm on this kernel/Xorg path
(fractional scaling + multi-monitor + Meet/WebRTC load appears to trigger it).
