Subject: [PATCH] monitor-manager-xrandr: Work around spurious hotplugs on Xvnc
|
||
|
|
|
||
|
|
Xvnc turns its outputs off/on on every mode set which makes us believe
|
||
|
|
there was an hotplug when there actually wasn't. Work around this by
|
||
|
|
requiring new randr configuration timestamps to be ahead of the last
|
||
|
|
set timestamp by at least 100 ms for us to consider them an actual
|
||
|
|
hotplug.
