Bumblebee issue with Ubutnut 12.04.1 LTS 64bit on Dell Vostro 3750, solved by acpi_backlight=vendor
Hi all,
Ubuntu 12.04.1 LTS \n \l
Linux simon-Dell-System-Vostro-3750 3.2.0-31-generic #50-Ubuntu SMP
Fri Sep 7 16:16:45 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
optirun (Bumblebee) 3.0.1
Couldn't get
$ for keyword in baseboard-manufacturer baseboard-product-name
baseboard-version system-manufacturer system-product-name
system-version bios-vendor bios-version bios-release-date; do
printf "%-22s: " "$keyword";
sudo dmidecode -s "$keyword";
done
to work, I pasted it in to terminal to no avail and tried it in a
shell file to no avail. I also have a launchpad account but could see
no way to email (with attachment's) from it.

I found that everytime I turned the laptop on, the display would die.
acpi=off and/or acpi_backlight=vendor seem to fix it but I have no
idea if they are ideal, I'm of the personal opinion that
acpi_backlight seems to be the least impact to power management etc.
I found this solution on the mailing lists and it's not covered on
https://github.com/Bumblebee-Project/Bumblebee/wiki/Troubleshooting so
it might be worth adding it.
Thanks for doing Bumblebee, it's a cool bit of kit.
Best Regards
Simon
