ERROR_GRAPHICS_NOT_A_LINKED_ADAPTER

Interpret the result in its owning layer: graphics not a linked adapter

ERROR_GRAPHICS_NOT_A_LINKED_ADAPTER (0xC0262430) belongs to the linked layer. It marks the selected adapter is not part of a linked display adapter configuration, rather than a generic rendering failure. The object that owns the decision is linked-display-adapter membership.

This result: Linked-adapter failures are ordered PnP and power problems. Restarting only the lead member can make the state less consistent and hide the first failing chain device. The built-in one-line message identifies the immediate result; diagnosis also needs the producing API, object ownership and the display generation current at the time.

Capture before recreating objects

Preserve the unsigned HRESULT, symbolic name, first failing API and timestamp in one record. If cleanup later fails too, keep that secondary result separately from this result.

Reproduce one variable at a time

  1. Freeze the result generation. Record adapter LUID, device instance, linked-adapter enumeration, driver package and topology role. Before diagnosing this result, do not resize, hot-plug, recreate or release the object under examination.
  2. Run the narrow this result comparison. run the linked-adapter operation on a verified lead or chain member. During the result comparison, keep every driver, monitor, resource format and unrelated policy unchanged.
  3. Observe the layer after it. for it, if the exact check passes, record the next HRESULT or visible outcome. A different downstream result shows that the boundary was crossed.
  4. Repeat it through a lifecycle transition. for it, exercise one relevant resize, mode switch, device recreation, hot-plug or session change and confirm that it does not reuse stale handles.

The comparison with ERROR_GRAPHICS_LEADLINK_NOT_ENUMERATED is especially useful: ERROR_GRAPHICS_LEADLINK_NOT_ENUMERATED applies after a linked configuration is known. Recording both names prevents a broad “graphics error” label from merging distinct ownership, capability and lifetime problems.

Recovery contract

Gate linked-only operations on enumeration results and use ordinary adapter handling otherwise. Repair of it is complete only when the original call succeeds or returns its documented nonfatal status and the same lifetime test remains correct after a second display transition.

Implementation notes

Log device-instance IDs, lead/chain role, PnP problem codes, Dx states and start/power IRP ordering. When the path returns a count, size, status flag or replacement object, retain it even on a nonfatal result because it can direct the next call.

A production fallback for it should be explicit: pause rendering, re-enumerate, rebuild one cache entry, recreate a device, or decline a protected path only when this layer calls for that action. Reinstalling every display component, deleting all caches or forcing a resolution change is not an evidence-based fix for it.
