Bug description:
I have installed Ubuntu 18.04 LTS on my laptop which is a Lenovo Ideapad 300
with 8GB of RAM, an Intel® Core™ i7-6500U CPU @ 2.50GHz × 4 processor and
Intel® HD Graphics 520 (Skylake GT2). I have GNOME 3.28.1 which logically is
latest version of GNOME coming with Ubuntu 18.04 LTS. Everything works
perfectly but I found a bug which happens when logging in. When I boot my
laptop (which is not dual boot, it only has Ubuntu 18.04 LTS installed), I
press Enter to select the only available user (my user) and then I am prompted
to enter my password. If I type my password wrong by a character more
(I haven't tried a smaller or a bigger length) and then give the right
password the GUI crashes. What I mean by crashing is that I get a static purple
screen where I can only move my mouse pointer and nothing else. I get no
desktop, no icons, no nothing. I don't know if it is a hardware incompatibility
or a bug but it happens every time I follow the steps I mentioned above and
then I have to hard shutdown the laptop.
