This is not a bug in the driver but a combination of several bugs in xserver Git (the 1.6 releases aren't affected) and in gnome-screensaver (http://bugzilla.gnome.org/show_bug.cgi?id=581995). Created attachment 25671 [details] [review] xserver fixes This patch fixes the worst problems in xserver Git with an RandR 1.2 capable driver: * Properly maintains and returns to clients the VidMode extension gamma value. * Fixes the calculation of CRTC colour LUT values from this gamma value. It looks like the patch has been applied to master with commit 2c1190f. With current master (commit 8609a4e) the problem still exists, but the colours are reversed. Whereas the screen appeared whitened, it now appears blackened. I'll attach another photo. Created attachment 25895 [details]
Blackened screen
(In reply to comment #7) > It looks like the patch has been applied to master with commit 2c1190f. Indeed, but I forgot to resolve this bug... doing so now. > With current master (commit 8609a4e) the problem still exists, but the colours > are reversed. This is due to the referenced gnome-screensaver bug, which causes it to set the gamma to 0.1. You can restore it with something like xgamma -gamma 1.0 |

Created attachment 25662 [details] Normal screen Before the screensaver kicks in, gnome tries to fade the screen to black. This causes the screen to whiten with particular bits of text and other on-screen elements having appearing bold in comparison. Software screenshots of the whitened display show no difference to a normal display, however I've attached photos of the monitor that do show the difference.
