--- Comment #27 from Thomas Bosch <tbosch at gmx.de> ---
Why is the bugfix within commit 38aecea0
(https://github.com/torvalds/linux/commit/38aecea0ccbb909d635619cba22f1891e589b434)
reverted in v3.15.7
(https://github.com/torvalds/linux/commit/c6930992948adf0f8fc1f6ff1da51c5002a2cf95)?

Before v3.15.7 all works fine for me. I can plug the second screen to my DELL
e-port-dock and the display works as expected. After switching to > v3.15.7
(i.e. v3.16.0) my problems come back.

When the system resumes from sleep it needs half a minute to switch on the
external display. Same is when switching to console with CTRL+ALT+F1.

It seems, that the bug initially fixed with
https://bugs.freedesktop.org/attachment.cgi?id=92231 is back again.
