    Version bumped to 0.6.147
    
    This version fixes an intermittent DVI power on failure bug when
    resuming from standby (ACPI S3 State) on models that use the
    integrated TMDS transmitter found in CX700 / VX700 and VX800 chipsets.

commit f067bea48f1973abf8bd4b5ce82cb4dd46ad38ba
Author: Kevin Brace <kevinbr...@gmx.com>

    Disabling various FP related registers when DVI is in use
    
    After further testing, it turns out that VX700 chipset’s hardware
    based FP power on circuit fails about half of the time when resuming
    from standby (ACPI S3 State) on Xubuntu 14.04‘s X.Org X Server 1.15.1.
    Code will now use software based power on control instead. This fixes
    an intermittent DVI power on failure bug.
