Loose xfce desktop when HDMI disconnected

[altman]

Glad that you fixed the wifi issue , hope it wont take too long to fix other issue . It s a nice How To .

Update,

It appears the WiFi Fix is not stable... After a period of time, 1 ~ 2 hours it starts to disconnect.
I'm going to start another thread, otherwise this thread will become even more confusing.

Gee that sux , tought it was resolved .

To put this thread back on track.

Summary:
I have a Monitor with 2 X HDMI inputs
Original PC ~ LL 2.0 on HDMI#1 , New PC ~ LL 2.2 on HDMI#2
If I swap the input on monitor between HDMI#1 & #2
I loose the xfce desktop on New PC on HDMI#2

It is not the monitor/cables I have swapped around cables and input sockets.

I do believe it is LL 2.2 config/set-up.?.. Why.??

In an effort to diagnose a separate WiFi issue I created a Ubuntu 14.10 (kernel 3.16) live boot USB stick.
(( WiFi issue to be described in another thread ))

What I found was If I boot the Ubuntu, I'm able to switch the display between LL 2.0 & Ubuntu without any issues.
To re-verify, I then booted my LL 2.2 Live USB stick, I see the same issue with Live and Installed, If I switch my
monitor input I loose my desktop. The only way to get it back is a ctrl-alt-F3 and do a:

Code:

sudo service lightdm restart

Thanks... Dave

Hi,

I'm hoping somebody can help out on this...
It's like something in xfce configuration get's lost/messed up when LL is not seeing a display.??

Hi,

Not giving up, more Googling led me to this:
It talks about TV on HDMI being turned OFF,
Which is what I suspect the result of me me switching inputs on the display.??
https://bugzilla.xfce.org/show_bug.cgi?id=11107

It seems like it's what I'm experiencing,, But not sure what to do.?
There are some patches, but I have no idea what to do with them.?

There is also this:
https://bugs.launchpad.net/ubuntu/+sourc...ug/1308105

Any pointers on what to do welcome
