Bug ID: 109336
Summary: gma500_gfx misdetects LVDS-1 as connected causing
black screen
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: minor
Priority: medium
Component: DRM/other
Assignee: dri-devel@lists.freedesktop.org
Reporter: dominik@greysector.net
On a Thecus N5550 NAS box (Intel Atom D2550/Cedarview platform), the gma500_gfx
driver detects LVDS-1 output as connected (it's not):
Jan 13 13:15:09 kernel: [drm:drm_helper_probe_single_connector_modes
[drm_kms_helper]] [CONNECTOR:36:LVDS-1] status updated from unknown to
connected
Only VGA-1 is connected, but that's detected correctly. This causes black
screen after kernel loads the driver. Adding video=LVDS-1:d to the kernel
command line works around the issue.
The kernel version is 4.19.13-300.fc29.x86_64 (Fedora 29). Kernel output with
drm.debug=0xe:
