            Bug ID: 101447
           Summary: Nouveau on GP106 can't work with another framebuffer
                    drivers (possibly uvesafb)
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau at lists.freedesktop.org
          Reporter: barracuda72 at bk.ru
        QA Contact: xorg-team at lists.x.org

At boot then uvesafb first picked up and then replaced with nouveau screen goes
into distorted state. X can be run but nothing apperars on the screen except
garbage. Switching between VT's works, but screen is still distorted.
Disabling all other framebuffer drivers in kernel config helped to solve this
issue.
