Patch against kernel 3.14.1 that fixes the problem
Prior to commit 24576d2 (linux stable tree), everything worked fine. With the
commit, the xserver starts much slower after a prior resume from S3, the
monitor is switched off and on again, the kde splash screen is displayed in the
upper left corner (1024x768) on my 1280x1024 monitor. mplayer -fs plays a video
correctly, but the (normally) black bars above and below the video contain
garbage for x > ~1024 / y > ~768
Steps to reproduce the problem:
boot linux,
startx,
suspend (s3),
resume,
terminate xserver,
startx,
mplayer -fs foo.video
Reproducibility: 100% on my system (AOpen i915GMm-hfs mobo with Pentium-M
Dothan cpu, Eizo Flexscan L557 monitor)
Attached is a patch against 3.14.1. Directly reverting 24576d2 is impossible as
a helper function was eliminated, a file was renamed, and other patches touched
the code, but more or less my patch is simply a functional revert of 24576d2.
cu,
Knut</pre>
