Cannot find display configuration

[Tony Pursell]

When booting an error window is displayed. The only option that works is to use the default configuration.

This problem has been introduced by an upgrade in recent months, i.e. since April 2018

See errors in the xorg log

[Tony Pursell (ajpursell)]

Bug has been fixed in upgrade just released including kernel 4.4.0-131.

Even though the bug was reported against 4.4.0-124, it was also present in releases between that and 4.4.0-130

[Tony Pursell (ajpursell)]

It seems I spoke too soon.

When I started the machine back up again today using 4.4.0-130, the bug was back again.

It seems that when I restart, sometimes it will start without the error message, then it will be back again if I restart again. Its quite random.

Another thing I have noticed is that if I get the xorg error message, I also lose the WiFi.

Your CPU model suggests you will hit bug 1727356. Please try the workaround from that.

[Daniel van Vugt (vanvugt)]

Oops, sorry. Not bug 1727356 because you are running 16.04 and Unity.

[Tony Pursell (ajpursell)]

Hi Daniel

I'm grateful that you mentioned bug 1727356. I would have taken the opportunity to upgrade to 18.04 but I see that I will have to wait until it is fixed.

[Tony Pursell (ajpursell)]

Here's an update on this...

If, when in GRUB, I select the Advanced option and then choose the (upstart) option, it works OK.

If I do the default boot, it nearly always results in the error message and no wifi.

I hope this will give you some idea of what is going wrong.
