I'm running a Dell Inspiron with an Intel video driver and up-to-date
F23 64 bit installed, GNOME3 desktop. I'm looking for suggestions to
improve stability, as I'm crashing 3 - 4 times a day and can't afford
to lose work in progress in LibreOffice, consoles and Chromium.
Crashes are almost always occurring when I click on a link or UI
element, instantly dropping me back into the login screen. Running
ABRT, I've posted bugs to Bugzilla (see below).

If anyone has a similar setup and had found more stability by
downgrading a driver, tweaking settings or switching desktops, I'd
welcome any suggestions.

Intel® Core™ i5-5200U CPU @ 2.20GHz × 4
Intel® HD Graphics 5500 (Broadwell GT2)
Memory 11.6 Gb
GNOME Version 3.18.2
