[Bug 1314213] Re: [Lenovo ThinkPad X220] External DP1 monitor extremely unstable since upgrade to 14.04
This happens often when my laptop even with power supply left alone for
a while for the screens to get turn off. When I log back -in or press a
key to get to login screen, the second monitor never turns on. I have to
unplug and plug the monitor DVI cable to get the monitor to show the
screen.
I have verified that Ubuntu 14.04 thinks that both the monitors are on
even when just my laptop screen it working and external monitor is all
blank ( no signal ). This is happening on my lenovo x1 carbon which has
intel hd4000 graphics.

Title:
[Lenovo ThinkPad X220] External DP1 monitor extremely unstable since
upgrade to 14.04
Status in “xorg” package in Ubuntu:
Confirmed
Bug description:
Since upgrade to 14.04, using my Dell BIZLINK DisplayPort to DVI Dual
Link Adapter the external display on DP1 is extremely unstable. I get
constant "[drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving
up" messages over dmesg. I used to get those with 13.10, but there was
no stability issue. Once the laptop (Lenovo X220) is connected to the
monitor (resolution is 2560x1600), if I run any program like xrandr or
unity-control-center, the system immediately reverts from the external
display to the laptop display, and often crashes becoming
unresponsive. Every time I run xrandr or unity-control-center, it
triggers 20 "[drm:intel_dp_i2c_aux_ch] *ERROR* too many retries,
giving up" messages in dmesg and if I am using the external monitor it
further triggers a reproducible crash. It is possible that this might
be related to the DVI->DP adapter I am using. Due to an unresolved
bug, the correct EDID for the monitor is not recognized, and I have to
manually add that after each boot.
