<pre>Today I did some test with Debian testing (Kernel 4.14) and the bug is very
less serious.
1)The bug still happen if I disable my laptop screen at boot (video=LVDS-1:d).
2)The bug DOESN'T HAPPEN if I close my laptop screen in Gnome 3.26.2
To summarize:
1)From kernel 4.13, the laptop screen can't be disabled with a kernel parameter
or the bug will happen. This is the real problem.
2)With my dual monitor setup, kernel 4.13 and newer are incompatible with
Debian Stretch and Gnome 3.22(not really a problem because kernel 4.9 is
working great and allow me to disable laptop screen at boot time with
video=LVDS-1:d)</pre>
