Subject: ply-device-manager: Fall back to text plugin if no renderers installed
X-Git-Tag: 23.360.11^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=03842d5201e4486fe62635c7b470eb94696f985d;p=thirdparty%2Fplymouth.git

ply-device-manager: Fall back to text plugin if no renderers installed

If there's no renderers installed there's no point in continuing to
listen for DRM events and trying to load the drm plugin.

This commit just forces text mode right away in that case.
