Comment 2 for bug 2043324

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Bug reporting is about finding & fixing problems thus preventing future users from hitting the same bug.

I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709

*I've seen this before; esp. on older hardware, alas not recently. Lubuntu have their own discourse beyond the generic Ubuntu ones in my prior paragraph which maybe useful in support, but I do believe you'll get from support than trying to file a bug report; I recall swapping out sddm with another DM being a fix for some hardware*
