[Samsung NP535U3X-A01BD ] Display remains off after resume from suspend

[Lenin]

After I resume from a suspend, the display does not turn back on. However, I hear sounds as if just booted on to the login screen. But with all combinations of Keys, Ctrl-Alt-Delete, Space, lid-turn-on/off, backspace, brightness increase/decrease nothing helps to turn the display back on. The issue had been same with Lubuntu 13.04 and 13.10 as well.

WORKAROUND: Hibernate via:
echo disk > /sys/power/state

sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend"
sh: 1: cannot create /sys/power/pm_trace: Directory nonexistent

[Lenin (doctortomorrow)]

sudo -i

echo devices > /sys/power/pm_test
zsh: no such file or directory: /sys/power/pm_test
echo platform > /sys/power/disk
echo disk > /sys/power/state
dmesg > /tmp/dmesg-devices-platform.txt

[Lenin (doctortomorrow)]

Amazingly,

echo reboot > /sys/power/disk
echo disk > /sys/power/state

The above pair of command works for the suspend/hibernate!

After executing it goes to suspend/hibernate and then after pressing power button it successfully turns on back to its past state!

https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume Followed this guides.

So, for now, I am suspending with this: echo disk > /sys/power/state

[Lenin (doctortomorrow)]

Also, need to mention: https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume#Dead.2C_Blank.2C_or_Black_Screen_on_Resume grub nomodeset option doesn't resolve this exact issue.

Should the machine fail to resume, first attempt to manually resume it. If
that fails power your system off and on which will generate an apport bug

Lenin, thank you for reporting this and helping make Ubuntu better. Because Samsung does not easily reveal what the latest BIOS is for this model, could you please download the latest firmware software as per http://www.samsung.com/in/support/model/NP535U3X-A01BD-downloads , and advise if a BIOS update is available? If so, when you update to this following https://help.ubuntu.com/community/BiosUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Thank you for your understanding.
