<pre>Hello,
I have installed a brand new HP EliteBook 820 G2 with Debian Stretch, which
includes the Xorg server version 1.17.2 and the Intel driver 2.99.917.
At boot, the Linux console is fine. Then I start Xorg, and when I get back to
the console (either through quitting Xorg or ctrl-alt-f2), the console output
comes back, but the horizontal synchronization seems to be nonfunctional: the
output keeps scrolling horizontally. I can type text, run commands, etc. so
it's really just the output which is buggy.
One very odd thing is that if I consume CPU (e.g. through while true ; do : ;
done), the display becomes perfectly stable and the console is usable again.
This doesn't depend on the CPU which I run that on. I guess this may be related
with CPU sleep modes.
Downgrading the Xorg server to 1.16.4 and the intel driver to 2.21.15 fixes the
issue, I'll probably try to bisect a bit (at least try to use the same Xorg
server)
This is basically making my laptop unusable for my work without a downgrade :)</pre>
