Package: slim
Version: 1.4.1-1devuan1
Severity: normal
Tags: patch
Dear Maintainer,
This was reported on devuan's forum by Eeqmcsq at
https://dev1galaxy.org/viewtopic.php?id=7501
When no monitor is attached to the system on startup,
slim will crash in a call to XGetWindowAttributes(),
due to slim's root window having a height and width of 0.
The patch sets non-zero default fallback values for the
display's width and height.
Patch is below. I'll also attempt to attach, if reportbug allows.
