dbe is not the intel driver. It stands for
double buffer extension.
The driver for intel cards is the
xf86-video-intel. It will probably show up as the i915 module in lsmod, for example
Code:
$ lsmod | grep i915
i915 321187 3
drm_kms_helper 25963 1 i915
drm 175314 3 i915,drm_kms_helper
i2c_algo_bit 4911 1 i915
video 19305 1 i915
intel_agp 29459 2 i915
button 4834 1 i915
i2c_core 18726 6 videodev,i915,drm_kms_helper,drm,i2c_algo_bit,i2c_i801
And no, there's no better driver.
