            Bug ID: 97308
           Summary: radeon driver does not handle HD 5770 and xrandr does
                    not detect screens , but only a default one
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Driver/Radeon
          Assignee: xorg-driver-ati at lists.x.org
          Reporter: diegogullo at gmail.com
        QA Contact: xorg-team at lists.x.org

after kernel upgrade i moved from fglrx to radeon on my HD 5770 as apparently
old proprietary drivers are not supported anymore.

As two screens are currenlty mirrored (instead of extending) and using a non
optimal resolution I wanted to configure xorg.conf to force a better set up. It
used to work before upgrade

So i start by 

---
$ xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 400, current 1280 x 1024, maximum 1280 x 1024

   640x480        0.00  
   720x400        0.00
---

I cannot see the screens here so i assume xrandr has a bug as i was expecting
at least two entries.

I assume the current bad experience with the driver is a bug as my gfx is
supported in theory by radeon out the box. Also xrandr looks very buggy on my
system. 

Any thoughts? Should i add more info?
