The Greeter sometimes does not display the GNOME Shell top bar
_Originally created by @intrigeri on [#12548 (Redmine)](https://public-redmine-archive.tails.boum.org/code/issues/12548)_
On 3.0\~beta4. The desktop background was black and the corners of the
greeter’s window were square. Only relevant logs I could
find:
May 16 11:33:15 amnesia gdm-shell-tails.desktop[3502]: X Error of failed request: XI_BadDevice (invalid Device parameter)
May 16 11:33:15 amnesia gdm-shell-tails.desktop[3502]: Major opcode of failed request: 131 (XInputExtension)
May 16 11:33:15 amnesia gdm-shell-tails.desktop[3502]: Minor opcode of failed request: 59 ()
May 16 11:33:15 amnesia gdm-shell-tails.desktop[3502]: Device id in failed request: 0x27c
May 16 11:33:15 amnesia gdm-shell-tails.desktop[3502]: Serial number of failed request: 253
May 16 11:33:15 amnesia gdm-shell-tails.desktop[3502]: Current serial number in output stream: 253
… immediately after X.Org detected the “spice vdagent tablet”. And
indeed, there’s no running `gnome-shell` process for the GDM session. I
wonder if this might be related to `set-cursor.py`.
The keyboard layout and admin password I’ve set was successfully
applied.
