Summary: Unused bands in intefb console and smaller 180x56 -> 128x48 Product: Drivers Version: 2.5 Kernel Version: v2.6.30-rc8-5-gc9fb15f Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI) AssignedTo: drivers_video-...@kernel-bugs.osdl.org ReportedBy: sa...@agolina.net CC: kei...@keithp.com Regression: Yes Created an attachment (id=21768) --> (http://bugzilla.kernel.org/attachment.cgi?id=21768) Xorg.0.log, just in case there is useful info Hello, I've tested the code in latest linux-2.6.git (v2.6.30-rc8-13-gb87297f) and I've found a regression. Now I have unused screen in the bottom and the right of the screen, additionally the size of the console also change, 180x56 -> 128x48. -Console: switching to colour frame buffer device 180x56 +Console: switching to colour frame buffer device 128x48 I've bisected it down to: commit c9fb15f60eb517c958dec64dca9357bf62bf2201 Author: Keith Packard <kei...@keithp.com> Date: Sun May 31 05:42:28 2009 drm: Hook up DPMS property handling in drm_crtc.c. Add drm_helper_connector_dpms. Making the drm_crtc.c code recognize the DPMS property and invoke the connector->dpms function doesn't remove any capability from the driver while reducing code duplication. That just highlighted the problem with the existing DPMS functions which could turn off the connector, but failed to turn off any relevant crtcs. The new drm_helper_connector_dpms function manages all of that, using the drm_helper-specific crtc and encoder dpms functions, automatically computing the appropriate DPMS level for each object in the system. This fixes the current troubles in the i915 driver which left PLLs, pipes and planes running while in DPMS_OFF mode or even while they were unused.
