#7531 obsolete 3D Acceleration fails in Linux guests Technologov
Description

3D Acceleration fails to accelerate many things -- glxgears, Compiz and KDE4 composition desktop.

Host: Windows XP, Intel Core 2 Q6600, ATI Radeon HD 3850, VBox 3.2.8

Guest: openSUSE 11.3 x64

Other Affected Guests: openSUSE 11.1/11.2/11.3, Fedora 12, RHEL6 (BETA1) (both 32 & 64bit)

  1. openSUSE/KDE3: Running "glxgears" on openSUSE guests makes them run at 250-500 fps, which is a "software rendering" performance.
  1. openSUSE/KDE4: I have tried to activate KDE4 kwin desktop compositing, but this failed, resetting to 2D mode. How to debug?
  1. Red Hat/GNOME: Tried to activate Compiz from GNOME menu, but this failed, resetting to 2D mode. How to debug?

#7532 obsolete Max Screen Resolution wolf
Description

There is no reference in the User Manual regarding what max screen resolution can be, and no instruction how to get it. The intuitive, or shall I say the standard way, by setting it in the Guest, is not supported by VirtualBox. Rather, it is done unintuitively by setting Machine->Auto resize Guest Display (Host+G). Feedback on whether it has been done or not is then given by hiding a tick mark inside an icon.

It is possible to do so, and technically-minded users should not have a problem with it. Better usability is achieved, for more users, by

  1. spatially separating icon and tick mark
  1. making auto resize the default
  1. doing away with the menu item, having only an automatically resized window
  1. having an entry in the user manual

#7534 obsolete OpenGL 3D mouse cursor invisible in Windows 7 guest Selden Ball
Description

Problem:

When the mouse is captured (i.e. when mouse integration is disabled), the cursor used by Celestia v1.6.0 (a multi-platform 3D astronomy display program) is invisible. It disappears when the cursor position is within the 3D window. The Windows default arrow appears when the cursor leaves Celestia's 3D window.

While slowly moving the cursor into the 3D window, I can see one of the arms of the cursor (a large plus sign) extending past the window border onto the desktop just as the cursor enters the window. None of the cursor's arms are visible in the 3D window itself.

When the mouse is not captured, the cursor is visible in the 3D window and changes back to Windows' default arrow when it leaves Celestia's 3D window, but mouse interactions with Celestia don't work right.

Once I saw a very tiny cursor while the mouse was captured, but was unable to see it in subsequent tests.

As best I can tell, the symptoms are exactly the same whether running VB in full screen mode or in windowed mode.

(I'm sorry if this is a duplicate problem report. I was unable to find any previous mention of this issue except for a hint in ticket #475, which is closed.)
