           Summary: [GMA 3150] works needs nomodeset to work decently
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: cpanceac at gmail.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: Driver/intel
           Product: xorg

On Intel D525MW motherboard (dual core atom inside) anaconda in f19 shows only
a unmovable mouse cursor if booted without nomodeset. With nomodeset, install
can proceed, After install, without nomodeset Gnome3, Cinnamonn, Mate and Xfce
show no desktop icons and no panels. With nomodeset, all these are shown even
though X uses software rendering to display them, thus heating the processor.

On Board Device Information
        Type: Video
        Status: Enabled
        Description: Intel(R) GMA 3150 Video Device

Monitor is connected to VGA

Steps to reproduce:
1.MAke kdm your default display manager
2.Boot without nomodeset
3.Select Gnome/Cinnamon/Mate/Xfce, as session

Expected results:
Panels and desktop icons are there

Actual results:
No panels, no desktop icons. Always.

More info:
On the other hand, i"ve seen keyboard locked, when booting with nomodeset and
, when using text interface, sometimes (most of the times?) the screen gets
scrambled with coloured numbers and other chars, after typing a few lines (like
user name and password). Switching back to GUI and then back to text, seems to
restore text visibility.

I"ll attach the other required info after rebooting with drm.debug=0x06 and
without nomodeset.
