Xorg problem (apport gave no details, sorry)

[thom]

Apport came up for unknown reason, bug seems to be in Xorg according to apport.
Everything seems to work OK though.

This happened on a machine that is only used for testing Lubuntu 14.04, therefore I am not restricted (and would be glad to help) to test things if needed.

[Apport retracing service (apport)]

This crash has the same stack trace characteristics as bug #1174698. However, the latter was already fixed in an earlier package version than the one in this report. This might be a regression or because the problem is in a dependent package.

maybe this info adds something new ?

[thom (tsk)]

I think I found something:

Every update first installs the kernel (which triggers DKMS ?) and complains about kernel headers missing
Then it installs kernel headers, but probably too late.

This results in triggering apport complaining about firmware stuff.

If I re-install the kernel and reboot, everything runs (compiles?) okay.

Maybe Update should install kernel-headers first ?

Status changed to 'Confirmed' because the bug affects multiple users.

I have a similar problem with Intel drivers on Dell Inspiron N5110. At startup, I get the error that you can see in the attached file. After the system is loaded, manually doing "sudo service lightdm start" works and X runs normally.
I am not sure if my problem is compatible with the posted bug, but if I can help with tracebacks of X server, please tell me how to do it.

Ubuntu 14.04 (trusty) reached end-of-standard-support on April 25, 2019.

18 duplicate bug reports (as per Apport Retracing) and no comments since
late April 2014 imply this issue was fixed along time ago.
