It seems the instructions at https://help.ubuntu.com/community/MacBookAir3-2/Narwhal describe how to work around this issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/746174 Title: Screen corruption on Macbook Air (Nvidia 320M) To manage notifications about this bug go to: https://bugs.launchpad.net/mactel-support/+bug/746174/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 746174] Re: Screen corruption on Macbook Air (Nvidia 320M)
This problem still exists in the Precise Pangolin beta 1. Is there something that can be done in Ubuntu to enable an install from CD without workarounds? If not, would someone at least consider writing up a step-by-step guide to booting/installing Ubuntu on a Macbook Air with the 320M chipset? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/746174 Title: Screen corruption on Macbook Air (Nvidia 320M) To manage notifications about this bug go to: https://bugs.launchpad.net/mactel-support/+bug/746174/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Confirmed the bug is still present in kernel 2.6.39-rc4 (http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.39-rc4-natty/).

This is a bug in nouveau, not the proprietary NVIDIA drivers.

[Bug 746174] Re: Screen corruption on Macbook Air (Nvidia 320M)
I notice there is a difference in vertical refresh rates: nouveau: 1366x768@60 = broken/corrupt nvidia: 1366x768@50 = working In fact, when using nvidia it doesn't let you go above 50Hz, suggesting the 60Hz used by nouveau is partly to blame. Though I know a mode setting is made up of several variables, so doubt the problem is just the vertical refresh rate. I also tried creating a 50Hz mode with cvt and xrandr, but so far have had no luck eliminating the corruption. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/746174 Title: Screen corruption on Macbook Air (Nvidia 320M) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Correction: nouveau is part of the mainline kernel now, so the package is linux. Also note; this is not an X11/xorg bug because it happens on the framebuffer before X even starts. ** Package changed: nouveau-kernel-source (Ubuntu) = linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/746174 Title: Screen corruption on Macbook Air (Nvidia 320M) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
