[Kernel-packages] [Bug 1495110] Re: External VGA port on laptop does not work anymore
Yes, it works with 3.13.0-63 after BIOS update. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1495110 Title: External VGA port on laptop does not work anymore Status in linux package in Ubuntu: Incomplete Bug description: I have been using the laptop for almost 2 years now, and I have not had problem connecting to a projector via the external VGA port until recently.

I use this laptop for teaching, so the only thing I know is that it was working in April and it's no longer working in September (I haven't tried in between). The reason I suspected it was the kernel was based on a web search of similar problems (though none seems exactly the same as mine, and most seem to say 3.16.0 fixes things). I may not be able to get to trying a new kernel until later this week, but I'll report when I have it done. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1495110 Title: External VGA port on laptop does not work anymore Status in linux package in Ubuntu: Incomplete Bug description: I have been using the laptop for almost 2 years now, and I have not had problem connecting to a projector via the external VGA port until recently.

Public bug reported: I have been using the laptop for almost 2 years now, and I have not had problem connecting to a projector via the external VGA port until recently.

As soon as I switch back to GUI the VGA output stopped working. The "Display" setting in System Settings cannot find an external monitor, nor could xrandr. My current work around is to use the HDMI port with an HDMI -> VGA converter. That seems to do the trick for now. Both Display setting and xrandr can see the HDMI connection.

Sometime between April and now, there must have been a kernel upgrade that messed it up. I saw a few other bug reports that eventually suggests I go to kernel 3.16.0. When I was on 3.13.0-63, my VGA output would work with the boot up screen and the log in screen. But once I log on the VGA port seems to be inactive and I can't get the output back. HDMI still seems to work, though the projectors I have access to don't have HDMI inputs. After I upgraded to 3.16.0, the VGA output would still work during the boot up and log in. Again, once I log on the VGA stopped working. However, when I switched to a text terminal (e.g. Ctrl-Alt-F1) I can see the VGA output again. As soon as I switch back to GUI the VGA output stopped working. The "Display" setting in System Settings cannot find an external monitor, nor could xrandr. My current work around is to use the HDMI port with an HDMI -> VGA converter. That seems to do the trick for now. Both Display setting and xrandr can see the HDMI connection.
