[Bug 13727] New: Visual Noise with radeonhd on ATI Radeon Mobility X1400
http://bugs.freedesktop.org/show_bug.cgi?id=13727 Summary: Visual Noise with radeonhd on ATI Radeon Mobility X1400 Product: xorg Version: unspecified Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Driver/radeonhd AssignedTo: lverhaegen@suse.de ReportedBy: steven@silverorange.com QAContact: xorg-team@lists.x.org When using the radeonhd driver on my Thinkpad T60p with an ATI X1400 (Fedora 8), I see slight visual noise across the entire screen. It's hardly noticeable from a distance, but when you look at large solid-color areas, or at anything close-up, it is clearly visible. It's difficult to describe, and I can't take a screenshot since it's happening on display. The best I can describe it is that it looks like slight JPEG compression noise, or like a color dithering (though the display is set to "Millions of Colors"). I've attached a faked image from the gimp that uses a "noise" filter to attempt to give an idea of what it looks like on a solid grey background. If I use the fglrx driver or the vesa driver, I do not see this noise. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug, or are watching the QA contact. _______________________________________________ xorg-team mailing list xorg-team@lists.x.org http://lists.x.org/mailman/listinfo/xorg-team -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

http://bugs.freedesktop.org/show_bug.cgi?id=13727 ------- Comment #3 from mhopf@suse.de 2007-12-19 01:40 PST ------- Looks like 18bit panel spacial dithering. Some people like it, some don't. This will be configurable in the future (if it is this issue). -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug, or are watching the QA contact. _______________________________________________ xorg-team mailing list xorg-team@lists.x.org http://lists.x.org/mailman/listinfo/xorg-team -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

This should already improve things for you. I will add configuration of which dithering is used in time, as i have more pressing issues at the moment. Report back with a recent version of the driver. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug, or are watching the QA contact. _______________________________________________ xorg-team mailing list xorg-team@lists.x.org http://lists.x.org/mailman/listinfo/xorg-team -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
