A) Regarding your comment: >"sudo apt-get install --install-recommends linux-generic-hwe-16.04 >xserver-xorg-hwe-16.04"
That doesn't confirm you are booted into the HWE kernel. That only shows that certain packages are installed (which you provided already in a previous comment). If you want to demonstrate what kernel is being using currently type: uname -a roger@roger-desktop:~$ uname -a Linux roger-desktop 4.13.0-43-generic #48~16.04.1-Ubuntu SMP Thu May 17 12:56:46 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux roger@roger-desktop:~$ B) Regarding your comment: >"...but now after additional other updates, and using Xdiagnose with various >settings, I haven't seen a boot problem for a few updates. I will continue to >monitor for a few days with Xdiagnose off to assure that problem is really >gone." Sounds good. B) Regarding your comment: >"...actually causes a problem in my system. It sets and locks the theme to >Ambiance, even though the setting properly shows Adwaita." Could be a bug, but that isn't the scope of this report. If you want it fixed, you would have to file a new report. C) Regarding your comment: >"Please tell me before I deal with this if this is possibly something done by >Xdiagnose..." Given you don't recall doing it, it was done by Xdiagnose when you checked its checkboxes. Response - ------------------------------------- A) roger@roger-desktop:~$ uname -a Linux roger-desktop 4.13.0-43-generic #48~16.04.1-Ubuntu SMP Thu May 17 12:56:46 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux roger@roger-desktop:~$ B) Will be checking for several days to confirm if I've just been lucky, or ??? - I'll hold off on filing a bug on Xdiagnose, I know how to fix it, and don't want to seem like I find too much fault. C) ok - Sounds logical to me. I'll continue to monitor, so please keep this bug report open for a while.
