Comment 9 for bug 769846

I noted that when boot hangs (during plymouth, but before kwin starts) the xorg.log always shows:

open acpi socket failed

then continues to load stuff ( amongst others glx nividea module)

then start loading dri2

and then complains it can not load the nividea driver.

I have not found a solution, but this work around seems to work:

press F8 during plymouth and kwin starts.

Now xorg shows acpi socket openede succesfully
