[Bug 1767760] [NEW] plymouth timeout prevents x-server from correct initialization

[Thomas Schustek]

Public bug reported:

After upgrading from plymouth_0.9.2-3ubuntu13.3 to
plymouth_0.9.2-3ubuntu13.4 about 50% of all x-server initializations
failed and Xorg crashed after entering fail-save-mode. A typical reason
for this behaviour was that it could not acquire DRM interface
/dev/dri/card0 not have been release before by plymouth after a time-out
condition.

Downgrading to plymouth_0.9.2-3ubuntu13.3 fixed the issue same as
elongating the time-out-interval from 2.0 to at least 6.0 seconds in
src/client/plymouth.c.

Ubuntu 16.04.4 is running on a about 9-year-old notebook with an Intel
Core 2 Duo U9400 @ 1.4 GHz CPU and a non-solid-state-disk. Its rather
complex xkb configuration takes more than a second to compile.
