           Summary: Radeon Mobility X700 LVDS internal panel is all white
                    when a CRT is connected on boot
           Product: xorg
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: chithanh at cs.tu-berlin.de
         QAContact: xorg-team at lists.x.org


Using xserver 1.4 and xf86-video-ati from git (tried both master and
atombios-support branch):
On my notebook (Mobility Radeon X700) the internal panel does not work
correctly if a CRT is connected on boot. When X is started, the panel will be
detected but display all white. (While on the console, the internal panel will
remain dark.)

However, if the CRT is connected after the system has started, the internal
panel works fine.

In Xorg.0.log there is one interesting difference:
---
-(II) RADEON(0): PLL parameters: rf=2700 rd=12 min=20000 max=50000; xclk=40000
+(II) RADEON(0): PLL parameters: rf=2700 rd=7 min=20000 max=50000; xclk=40000
---
Full logs will be attached.
