I tried this experiment:
Installed sshd and connected from another computer - it works. But
the lid closed and opened, I cannot connect. The system must be dead,
although the fans blows and the power led is on.
This means that your system hanged either during going into sleep mode
or when exiting the sleep mode. This is then not a screen issue but a
system issue. The fact that fans are on may indicate that the issue
happened when exiting suspend mode. But we definitely need more
Further after restart I found that nothing was written in neither
dmesg does not remember messages from old boot, you need to relay on
nor pm-powersave.log after the lid is closed and then opened.
yes this is normal as you rebooted. Then this file will be filled for
the next time but you won't be able to recover it. Normally you should
find a /var/log/pm-*.log.1, these files are the ones you need to
I marked both dmesg and pm-powersave.log by adding a specific line at the bottom and I am pretty sure that nothing is appended to them or to the renamed ones after lid closed and lid opened. Of course after restart the old files was renamed but my marks was still at the bottom of the old files.

Also it could be better if you try using the official Debian kernel, at
least while we are investigating the issue. I assume you have good
reason to use an other kernel, but we do not support such combinations,
so please ensure investigating this bug with:
(jessie)root@karim:~# aptitude show linux-image-amd64
Package: linux-image-amd64
State: not installed
Version: 3.14+58
Priority: optional
Section: kernel
Maintainer: Debian Kernel Team <debian-kernel@lists.debian.org>
Architecture: i386
Uncompressed Size: 38.9 k
Depends: linux-image-3.14-1-amd64
Provides: linux-latest-modules-3.14-1-amd64
Description: Linux for 64-bit PCs (meta-package)
  This package depends on the latest Linux kernel and modules for use on
PCs with AMD64, Intel 64 or VIA Nano processors.
This kernel also runs on a Xen hypervisor. It supports both privileged
(dom0) and unprivileged (domU) operation.
I DO prefer using standard official kernel, but 3.14 doesn't support my video card - shows a black screen after grub. Thats why I installed 3.15 and 3.16.

And all the thing had worked well till update at 07.07.
