Step to reproduce:
Note: I discovered this defect when trying to load a Live image of Mint 19.1. I've duplicated it using Ubuntu and Xubuntu. I'm logging it here because Ubuntu is the "base" codebase.

1. I boot from my USB drive. Usually, the UI loads, but sometimes I only get a blank screen.

2. Connect to Wifi.

3. After using the OS for a while, everything freezes. The mouse and keyboard inputs don't work.

4. This happens every time.

What I expected to happen: the UI and everything doesn't freeze. :-)

More info: I reported this problem here: https://www.linuxquestions.org/questions/linux-mint-84/problems-with-xfce-19-1-live-us-4175644671/
There might be some useful info here.

I'll be happy to assist, test or answer questions about this issue.

I suspect that this is related to the Desktop env. When I run Lubuntu, it works well. I've tested LXLE 16.04 (same Ubuntu version) and it works well also.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1810064/+editstatus and add the package name in the text box next to the word Package.

[This is an automated message. I apologize if it reached you inappropriately; please just reply to this message indicating so.]

[Richard (richb01)]

Well, I went over to https://wiki.ubuntu.com/Bugs/FindRightPackage and looked under Graphical Environment. I read the following test:

***
The following symptoms typically are due to GPU issues in the kernel DRM driver (linux package):

    Blank or solid-colored screen instead of login screen, or immediately after login
    System freezes completely
    Wrong default screen resolution
***

I entered "linux" as my package and receive the error that Linux is not a package.

I really like Ubuntu and I want to help, but the bug reporting system is, in itself, buggy.

"The following symptoms typically are due to GPU issues in the kernel DRM driver (linux package):"

I am not sure but suspect that means the kernel package, linux-image.

[Richard (richb01)]

Thanks! Finally got it to work.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1810064

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Richard (richb01)]

Due to the nature of this bug (a completely frozen screen, it isn't possible to get a log.

[Kai-Heng Feng (kaihengfeng)]

Please give 18.10/19.04 daily image a try.

[Richard (richb01)]

I DL'ed the 19.04 image and it seems to be working very well. I DL'ed from here: http://cdimage.ubuntu.com/daily-live/current/

HTH! Thanks!

[Steve Beeler (phucktround)]

This bug seems to affect my dell laptop as well (amd r6 with radeon video) when attempting to install either lubuntu or kubuntu versions 18.04.04, or 18.0.02 with a 4.15.x kernel. I think it may be related to the kernel itself as the bug seems to be related to hwe. I am going to try and do a lean install with ubuntu desktop and see if i can recreate my issue and apport.
