Right, but what's on Debian? Does the package xorg is relevant?

The freedesktop guys are responsible for the kernel, too. So it was

I've read the upstream thread, as I can understand, it's related to the 
kernel, isn't it? Why not forwarding the issue on the Kernel?


I've migrated from Jessie to Stretch yesterday and I found this issue 
really annoying, IMO the severity of this bug should be raised. We have 
to backport the fix on the stable branch. I cannot use a computer that 
has visual flashes regularly. I've spent one hour to figure out the 
issue and to find this bug.


I've apply the work around to save my life but a regular user couldn't 
do that.

Alex.

Hi,

I also had that bug.
I installed Stretch from scratch yesterday and noticed screen flashes
(or screen refreshs, I can't really say) sometimes when I was typing on
the keyboard. Once, I got a black screen quickly followed by a system
shutdown, I couldn't find much in the logs (with my knowledge).

Someone pointed me to this bug, I did the workaround (cp
xserver-xorg-video-intel's xorg.conf into /etx/X11), and the bug
disappeared. No more flashes. I hope the shutdown thing won't happen :)


Thanks,
gagz

sorry it took me so much time.

I upgraded xserver-xorg-core to 2:1.19.3-1 (in sid) and removed the
/etc/X11/xorg.conf file that was forcing xorg to load the intel driver.

I then restarted the X display and was able to reproduce the visual
flashes (or rather visible screen refresh) and hard crash followed by an
automatic shutdown about 10s later.

I've been using the intel driver by forcing it as was suggested to me
some time ago and haven't had any crash since then.

but yeah I could disable the force (, luke) and see if I can reproduce
the bug again with the newer package versions.

I'll see if I can do that on sunday

Note that I'm still at 2:1.19.0-3 (as at the time when I reported the
issue). So the problem was fixed by something different.

Hi,

Uwe reported that with a newest release of xserver-xorg-core, the 
bug disappeared. [1]

There has been new uploads recently in Stretch and Sid, which now have
2:1.19.2-1 and 2:1.19.3-1 respectively.

Is one of this versions the one supposed to have "fixed" the bug?

Could be helpfull if someone (lelutin?) gives a try back with the newest
modsetting driver so that we know if it eventually works.

Just a small note to let you know I have the same problem on my X201
with the exact same symptoms. Since switching to the intel driver my
system is stable again.

I already reported the issue to the upstream bug tracker and mark the
bug as forwarded accordingly.

right, no crashes either. I've been running with newest package and

I'm sorry for this big delay, but I've finally taken the time to test
this out.

I can confirm that the visual glitches and crashes are still present in
the latest version of the package, 2:1.19.0-2.

Also, when using the above-mentioned technique for forcing the driver to
"intel" (I've confirmed that it loaded by looking at
~/.local/share/xorg/Xorg.log.0), I don't see visual flashes anymore.

/usr/share/doc/xserver-xorg-core/NEWS.Debian.gz reads:

xorg-server (2:1.18.3-2) unstable; urgency=medium

  X now defaults to using built-in modesetting video driver on Intel
  hardware which is "4th gen GMA" and newer, so roughly speaking on hardware
  from 2007 and up. If this triggers new bugs on your hw, please file them
  against the xserver.

  Continuing to use the -intel driver is possible by dropping the template

So perhaps the modesetting video driver breaks things on your system.
Can you please try switching back to the -intel driver with 2:1.18.3-2
or newer?

Bug#837451: xserver-xorg-core: visual flashes followed by hard crash upon keyboard interaction with thinkpad x201

[Gabriel Filion]

Package: xserver-xorg-core
Version: 2:1.18.4-2
Severity: important

Hi there,

I've been having weird crashes that happen only when I interact with my
keyboard. It also happens with a keyboard plugged in to USB port.

I didn't know where exactly to look, so I "bisected" packages with the help of
snapshot.debian.org and found out that xserver-xorg-core version 1.18.3-2 was
introducing this issue. Downgrading to 1.18.3-1 makes the visual flashes and
hard crashes go away. I'm still seeing those crashes in 1.18.4-2

What happens is when I type on the keyboard, at some random point X crashes
(happens always exactly when I type a letter on the keyboard - if I let the
computer open without touching it, it doesn't crash).

Crash in this case means the screen goes black, sometimes there's a 1
pixel-wide vertical line on the left where color zizags randomly. The black
screen and left vertical column stay there for about 10 seconds before the
computer shuts down by itself. I have seen because of ssh connections that the
last letter I typed which caused the crash usually makes it through to the ssh
connection, but nothing after that goes through.

Also, before the crash happens, I saw that with gnome-terminal, if I switch
window or tab and start typing in the new window, I'll see a visual flash like
a quick blackout. If I repeat those flashes a number of time I end up
reproducing the crash.

Unfortunately, nothing in syslog or X.log ever shows up after a crash.
