[PATCH] drm/i915: no lvds quirk for hp t5740

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Last year, a patch was made for the "HP t5740e Thin Client" (see http://lists.freedesktop.org/archives/dri-devel/2012-May/023245.html). This device reports an lvds panel, but does not really have one.

The predecessor of this device is the "hp t5740", which also does not have an lvds panel. This patch will add the same quirk for this device. The dmidecode output is attached below the patch.

Regards,
Ben Mesman.
