Package: xfce4-settings

Version: 4.16.0-1

Severity: critical

On Debian and, by extension, Ubuntu, when suspending a laptop via closing the lid on XFCE, the screen stays black after resuming from suspend. The only way to "fix" the system is to blindly type "xrandr --auto" into a terminal or switch to a TTY and restart X.

This issue can be easily fixed by disabling Upower support when the package is compiled. However, despite being set as default in 4.16, Debian seems to have it re-enabled. Removing "--enable-upower-glib" from the configure flags in the package instantly solves this issue.
