           Summary: Duplicate video device for Toshiba Satellite A100-847
           Product: ACPI
           Version: 2.5
     KernelVersion: 2.6.23.9-85.fc8
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Power-Video
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


Most recent kernel where this bug did not occur: none
Distribution: Fedora
Problem Description:
There is a duplicate video device in Toshiba Satellite A100-847 laptop:

[EMAIL PROTECTED] ~]$ lshal | grep laptop_panel
  info.capabilities = {'laptop_panel'} (string list)
  info.category = 'laptop_panel'  (string)
  laptop_panel.access_method = 'general'  (string)
  laptop_panel.num_levels = 101  (0x65)  (int)
  info.capabilities = {'laptop_panel'} (string list)
  info.category = 'laptop_panel'  (string)
  laptop_panel.access_method = 'general'  (string)
  laptop_panel.num_levels = 101  (0x65)  (int)
[EMAIL PROTECTED] ~]$ 

This probably causes the problem that every Fn-F6 or Fn-F7 keypress the
brightness is changed by two values, as monitored by omnibook [1]. Now the
behaviour is even more broken, most probably due to bug #9277. Every keypress
gives two ACPI events:

10:22:54.773: computer_logicaldev_input_0 condition ButtonPressed =
brightness-down
10:22:54.773: computer_logicaldev_input_4 condition ButtonPressed =
brightness-down
