[Tommy Trussell <tommy.trussell@xxxxxxxxx>]

IN case anyone is tracking this bug -- I wasn't able to use Unity in
14.04 LTS at all with this card because there's no longer a 2D fallback.
I was tired of getting messages warning about losing hardware support
for the 12.04 kernels.

SO I finally worked around the problem by removing the ATI RV370 5B60
[Radeon X300 (PCIE)] video card and put in another cheapo one that
didn't have this problem (it's an [AMD/ATI] RV620 LE [Radeon HD 3450]).

I still have the video card with the bug but am no longer using it. I
believe the offending card came with the Dell as an OEM installation,
but it's generic.

** Summary changed:

- Dash Home not usable on Unity 3D for this hardware
+ Dash Home not usable on Unity 3D for Radeon HD 3450

** Summary changed:

- Dash Home not usable on Unity 3D for Radeon HD 3450
+ Dash Home not usable on Unity 3D for ATI RV370 5B60 [Radeon X300]

  Dash Home not usable on Unity 3D for ATI RV370 5B60 [Radeon X300]

Bug description:
  I finally upgraded this Dell Dimension E510 from Ubuntu 10.04 LTS to
  12.04.1 LTS and was distressed that when I clicked the Dash Home icon
  I see a flash across the top portion of the screen (maybe down to the
  second or third icon in the dock), but nothing apparently happens.
  This is PROBABLY a compiz thing but I decided to go ahead and report
  against Unity becaus the Dash is completely non-functional so maybe it
  needs a slightly improved fallback.

  NOTE If I log out and log in using Ubuntu 2D, everything works as it
  should. This failure only affects a "normal" ubuntu login.

  I believe this may be the onboard video for this hardware, though I
  can open up the box if you need to know.

  twt@dimension1:~$ lsb_release -rd
  Description:	Ubuntu 12.04.1 LTS
  Release:	12.04

  I did NOT do a release upgrade -- I booted from a USB stick upgraded
  by clicking the "install ubuntu 12.04.1" icon. I chose to preserve my
  files but upgrade Ubuntu in place. If you need any other info about
  the upgrade I can look for the install log or whatever. HOWEVER I
  believe when I tested 12.04 while in beta I had the same problem with
  Unity, but I waited until now figuring this bug would be squashed by
  now.

  When I test unity support, I get the following result:
  twt@dimension1:~$ /usr/lib/nux/unity_support_test -p
  OpenGL vendor string:   X.Org R300 Project
  OpenGL renderer string: Gallium 0.4 on ATI RV370
  OpenGL version string:  2.1 Mesa 8.0.4

  Not software rendered:    yes
  Not blacklisted:          yes
  GLX fbconfig:             yes
  GLX texture from pixmap:  yes
  GL npot or rect textures: yes
  GL vertex program:        yes
  GL fragment program:      yes
  GL vertex buffer object:  yes
  GL framebuffer object:    yes
  GL version is 1.4+:       yes

  Unity 3D supported:       yes
  twt@dimension1:~$ 

  I'm not sure what apport has collected -- I can send lspci -v or other
  info if needed.
