Yes, the problem went away with the new DP2VGA converter! I'm plugging it and the external monitor gets immediately recognized. Sorry for the noise in this report but I never would have thought that the DP2VGA adapter would fail in such a strange way. -- You received this bug notification because

I have a DisplayPort output and two adapters. DP to HDMI and DP to VGA. I have weeks to experience the issue with the DP2HDMI converter but it happens every time with the DP2VGA converter. I've ordered an other DP2VGA converter. Let's see. -- You received this bug notification because you are a m

Public bug reported: This notebook works fine for about 2 years (now on Ubuntu 12.04.5 LTS). A few hours ago I upgraded my kernel (apt-get dist-upgrade) to 3.13.0-52-generic #86~precise1. Don't know if it's related but now I got the following Oops while opening Gimp. I'll keep this kernel for now

ANYONE: Is there a way to get debug logs when this thing happens? Anyway to "reset" the VGA driver or anything except rebooting the whole machine? When pluging the external monitor dmesg shows nothing -- also greping /var/log shows nothing. I don't know where else to look. -- You received this

In my case things are (mostly) OK since a few days (I'm now on 3.13.0-46). One or two times it failed but I have no ideat what trigered the failure.

I have the same symptoms only _after_ upgrading to 3.13.0-44-generic. Can you test an earlier kernel version and see if the problem goes away? uname -a Linux ndXPS13 3.13.0-44-generic #73~precise1-Ubuntu SMP Wed Dec 17 00:38:38 UTC 2014 i686 i686 i386 GNU/Linux lspci|gre
