I don't know if you can get the physical colour depth from the EDID but doubt it.
When I first encountered such a problem it was a Macbook Air 11" with Nvidia graphics. I was shocked, but the good news is that the Nvidia driver does temporal dithering, so it looks nice (once you turn that feature on). Such temporal dithering done in the driver looks much nicer than doing it statically in an image. And of course, this is only the wallpaper. We can't easily fix it for the graphics you see in your application windows. Changing wallpaper is a trivial workaround, but it does disappoint me that we're degrading the quality feel of the out-of-box experience. Anyway, it's up to design... P.S. I use this awesome image to test if a display is any good: http://www.nasa.gov/multimedia/imagegallery/image_feature_347.html Looking at that gradient it becomes pretty obvious if you have a crumby 6-bit panel. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-wallpapers in Ubuntu. https://bugs.launchpad.net/bugs/1081702 Title: Update the default wallpaper in 13.04 Status in Ayatana Design: Fix Committed Status in “ubuntu-wallpapers” package in Ubuntu: Fix Released Bug description: We have got the 13.04 wallpaper ready ahead of schedule, so we might as well get it in the distro now ;-) See attached file "ubuntu_default_13_04.jpg" ------------------------------------ This change is part of a larger set of icon changes, the other bugs that are part of this same change request are: bug #1081704 (Dash - update the 'App Lens' icon asset in the Dash bottom lens nav bar) bug #1081702 (Update the default wallpaper in 13.04) bug #838854 (Workspaces, Launcher - The workspace Launcher icon should change depending on which workspace is currently being utilised) bug #1081697 (Launcher - Update BFB icon to use a new special asset) bug #1081687 (Launcher - Update Launcher tile assets) bug #1081691 (Launcher - Update the icons used for the Software Centre, Nautilus, and Software Updater) To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-design/+bug/1081702/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
