No acceleration with google earth

[Wise Ferret]

Using latest google earth and radeon driver from git 14/1/09 with x1600 on ubuntu intrepid, compiz disabled, I get the following message and no 3d acceleration:

 drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
Try adjusting the vblank_mode configuration parameter.

My xorg.conf:

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by failsafeDexconf, using
# values from the debconf database and some overrides to use vesa mode.
#
# You should use dexconf or another such tool for creating a "real" xorg.conf
# For example:
#   sudo dpkg-reconfigure -phigh xserver-xorg

Other 3d apps work fine. Any ideas how this can be resolved?

In my case, (Ati x1400, radeon-driver 6-10),
I changed the parameter vblank_mode in .drirc from 1 to 0, and after that googleearth worked fine. I don't quite know what vblank_mode means, but it worked for me

Thank you so much! This was it! I view your house from above now, bowing with gratitude.
In order to get a .drirc file I had to install first the package driconf and run it. Perhaps it should be a dependency of the radeon driver, or at least suggested by it.

You can use driconf (a GUI tool) to configure those options more easily.
