    Phoronix: ATI Radeon KMS Leaves Staging Area In 2.6.33

    David Airlie has called upon Linus to pull in a new set of DRM patches for the Linux 2.6.33 kernel, which should land with the Linux 2.6.33-rc7 release. These graphics patches for the Linux kernel bring a few fixes for TTM, Radeon DisplayPort tweaks, r600 blit mutex, and support for the VMware graphics driver with older versions of the VMware Workstation...

    It's not a bug. It's a limitation of the kernel framebuffer interface. It has no concept of multiple heads. In order to make sure no console information is lost the console is run at the largest mode supported by all attached heads. If you want full output flexibility, you'll need to use the kms interface like the X driver uses.
    Could the color at least be something other than white?
    It's painful to look at.

    So on my large screen, I get a white box around the framebuffer in the space it didn't fill.

    Though it is marked as regression I already had this with vanilla sources in 2.6.32 (so for me it is no regression). The issue though was fixed with the 2nd patch that was attached, as I wrote in my comments.
    Yes, the issue itself is basically what can be observed in the screenshots RealNC. Looks like this (crude hack) does solve things, will report back if I still see those issues.
    Looks like Jerome Glisse just wrote a proper patch for that bug today.

    I suppose I would first need to reinstall Git versions of all components along with a 2.6.33rc kernel and I'd rather not go through that again :P

    No, I thought they were known issues. Before I file a bug, are the following a known problem?
