Description Red 2019-06-01 01:06:26 UTC
Hi,

When libksysguard used Webkit as the backend for the Detailed Memory Information, it would only show me information on my own processes. In order to view the Detailed Memory Information for root processes, I would have to run ksysguard with sudo.

After the switch to Webengine, selecting Detailed Memory Information while running ksysguard as sudo, crashes with the following error:

[31732:31732:0531/205949.300034:ERROR:zygote_host_impl_linux.cc(89)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

(note: the numbers at the beginning are always different)

If you visit that link, people seem to be talking about problems with Google Chrome, not Plasma or KDE apps.

I tried running "sudo ksysguard --no-sandbox" but it exits with the error:

Unknown option 'no-sandbox'.

I'm completely confused about what's actually happening here. I don't even have Google Chrome or Chromium even installed.

Try:
sudo env QTWEBENGINE_DISABLE_SANDBOX=1 ksysguard

You may file a bug in https://bugs.kde.org/ in order for a more automatic solution to be implemented...

Yep that worked. Thank you!

This is upstream problem, not related to packaging in Gentoo.
