Title:
Xorg freeze after mouse pointer size change
Status in xorg-server package in Ubuntu:
Incomplete
Bug description:
I've attempted to change the size of my mouse pointer (Settings /
Universal Access / Cursor Size) from the default. As soon as I did
this the desktop froze and eventually turned black.
I could ssh in and would see the Xorg process consuming 100% cpu (per
top). After killing -9 that Xorg process, and resetting dconf reset
/org/gnome/desktop/interface/cursor-size I could log in to a new
session.
This seems reproducible, i.e. setting up pointer size again would give
me the same symptoms.
Apport probably collected this but jic, could see this in Xorg.log:
