Comment 2 for bug 1388430

1) I have installed driver 304.123 from Nvidia following the instructions provided at

http://askubuntu.com/questions/451221/ubuntu-14-04-install-nvidia-driver

2) I got the following error message:

The distribution-provided pre-install script failed! Continue installation anyway?

I chose 'Yes' and the installation process continued and finished, apparently, successfully.

3) I sent the log file (same file I attach here) to Nvidia Customer Care support team, and I'm waiting for their feedback now.

4) I was able to change my screen resolution (run gksudo nvidia-settings, because changing my screen resolution requires root privileges), so 304.123 seems to solve the issue. If Nvidia technicians confirm that everything is ok, I think 304.123 should be made available for Trusty, so any user who need it could install it with the 'Additional Drivers' wizard.

It's all for now.
