Just recently (late August / early September 2014) my multiple monitor setup and Nvidia optimus is not working. I had the symptoms characterized by this bug. After setting the BIOS to graphics card: integrated
and Optimus: disabled
, I was able to start Ubuntu, but it would not detect my external monitor. Then I uninstalled and re-installed Nvidia Primus. Then I tried both suggestions in the bug tracker, involving:
sudo apt-get install ubuntu-drivers-common=1:0.2.91.4
and
sudo dpkg -i ubuntu-drivers-common_0.2.91.5_amd64.deb nvidia-common_0.2.91.5_amd64.deb
(after downloading the associated .deb
's), rebooted, and reset the BIOS to graphics card: Optimus
and Optimus: enabled
, but I cannot detect the external monitor. Am I missing something, or are there any suggestions on how to proceed?
I am running Ubuntu 14.04 on a Lenovo W520.
UPDATE
Now that a fix has been released on ubuntu-drivers-common
, any suggestions on how to proceed? I am a bit skeptical because not all of the packages have been fixed, and the Trusty
description under ubuntu-drivers-common
says Triaged
. Is it okay to remove the hold from the packages described below, and is there anything else I should do?
A little explanation about the meaning of the bug's status would also be helpful. My interpretation is that a fix has been released for ubuntu-drivers-common
, and it is a workaround for the moment, because none of the other packages are fixed. Is that correct?
