Currently the driver's assumed behavior for a modeset with an attached FB is that the corresponding connector will be switched to DPMS ON mode if it happened to be in DPMS OFF (or another power save mode). This wasn't enforced though if only the FB changed, everything else (format, connector etc.) remaining the same. In this case we only set the new FB base and left the connector in the old power save mode. Fix this by forcing a full modeset whenever there is an attached FB and any affected connector is in a power save mode. V_2: Run the test for encoders in power save mode outside the the test for fb change: user space may have just disabled the encoders but left everything else in place. Make sure the connector list is not empty before running this test.

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).
The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:
1. The DRM provides synchronized access to the graphics hardware via
the use of an optimized two-tiered lock.
2. The DRM enforces the DRI security policy for access to the graphics
hardware by only allowing authenticated X11 clients access to
restricted regions of memory.
3. The DRM provides a generic DMA engine, complete with multiple
queues and the ability to detect the need for an OpenGL context
switch.
4. The DRM is extensible via the use of small device-specific modules
that rely extensively on the API exported by the DRM module.
Documentation on the DRI is available from:
http://dri.freedesktop.org/wiki/Documentation
