Bug#815630: 2.4.67-1 causes black screen after login on plasma desktop

[Sten Heinze <shze@gmx.de>]

Package: libdrm-intel1
Version: 2.4.67-1
Severity: important

Dear Maintainer,

Updating libdrm-intel1 from 2.4.66-2 to 2.4.67-1 causes a black screen after logging into the 
plasma desktop. Only the mouse is still visible and the blue glow around the start menu 
whenever the mouse moves over it. The function of the login screen (SDDM) is unchanged.

Downgrading libdrm-intel1 to 2.4.66-2 fixes this problem and results in a normally working
desktop.

Please let me know if I can provide additional information or can test different hypotheses.
