Bug Description

If I boot up with two external monitors connected, the login screen doesn't show up on any monitor.

The laptop display shows the mouse cursor on a blue screen, the HDMI monitor shows a blank blue screen, and the VGA monitor shows no signal.


WORKAROUND: Boot with only one external monitor connected.

Neal McBurnett, thank you for reporting this and helping make Ubuntu better.

1) As per the sticker of the monitors (not from the Bug Description, or the result of a terminal command), could you please provide the full manufacturer and model?

2) Are you using any dongles/adapters to connect to either monitor?

3) To clarify, if you boot up with nothing attach, then login, then attach both the VGA and HDMI, are you then able to configure all three screens to display the desired output while logged in?

4) Was there a release newer than Trusty, but older then Bionic where this issue wasn't reproducible?

5) Regarding desktop environment, are you presently using GNOME, Unity, etc.?

6) Could you please post the output of the following terminal command (not manually attach files):
ls -la /var/crash

Thank you, penalvch.

1) viewsonic vx2433wm model VS12324 2010-01-28
 samsung 22" led tv series 5 5000 model code UN22F5000AFXZA Version: FP02

2) For the HDMI connection from the thinkpad, I'm using an INSIGNIA DisplayPort-to-HDMI Adapter

3) Yes, except while I am then able to configure the two external screens, the laptop screen becomes blank. So I can use 2 out of the 3 screens. That was also a limitation in Trusty where I used Unity.

4) I haven't tried it on anything between trusty and bionic.

5) Standard bionic: Gnome 3.

6) This may be out-of-date, and I've pasted back in two crash files that I had moved to another directory at 10:57:
drwxrwsrwt 2 root whoopsie 4096 May 28 10:57 .

Neal McBurnett:

1) Regarding your crash files, please execute the following via a terminal to have them automatically processed:
ubuntu-bug /var/crash/FILENAME.crash

where FILENAME is the file name of the crash file to report.

The upload is successful when the file with extension .uploaded is subsequently created.

2) With regard to this report, you have at least two to three bugs here. One for each of the distinct crash files you noted, which reporting them will help to see them resolved. The third is along the lines of your Title+Bug Description:

From my cursory viewpoint, the crashes appear to be unrelated to the login issue reported.

Hence, for now, let this be marked a duplicate of LP#1760849. However, if after it is resolved your issue is still present, this report may always be unduplicated, and resumed from there.
