This is happening on my Lenovo T510 which uses Nvidia so I don't think
the video driver has anything to do with it. This bug (for me) is also
the worst kind in that it's intermittent. Tonight, the system locked up

The problem persists in 14.04. The solution in comment #96 still does
not resolve the issue for me.
I can confirm Rahul's observation in #116. Adjusting the brightness
before the kernel loads works. Adjusting after that freezes the system.

one workaround i been using for quite sometime now, is to decrease the
backlight before the kernel boots.
i.e. the system waits on grub bootloader for 5-10 seconds for any
distribution i used. dimming the display then bypasses this issue... :)

I believe I have successfully solved the bug now by reading all the
comments again and found a solution in #96. I added
echo 0 /proc/sys/kernel/nmi_watchdog
before exit 0 in the file etc/rc.local. I have used the system a few
hours/days/re-starts/hibernates since and no bug has occured by now.

I fresh installed Ubuntu 13.10, so it was using free drivers by default. And it
crashed when I tried to change brightness rapidly. So I think the bug is not
present in fglrx-installer. Now I am using AMD drivers, but my brightness
control doesn't work properly, it either increases or decreases
I never had this bug until yesterday. acpi_backlight=vendor and/or the
echo 0 /proc/sys/kernel/nmi_watchdog solution didn't work for me. I
couldn't install the latest mainline kernel, because of my restricted
broadcom WiFi driver I'm depending on.
Workaround for me was: Disable Virtualization

Marwan, your workaround did in fact fix the problem for me.
I'll add that when I tried your workaround (echo 0
/proc/sys/kernel/nmi_watchdog), I REMOVED acpi_backlight=vendor (which
I already had) at the same time. I rebooted and both problems were

This problem also occurs when brightness changes due to power on/off. In this

Hi,
I think adding 'acpi_backlight=vendor' to grub cmd option fix problem
for only Intel graphics cards, for other GPU this bug is still present.
This is very serious one. As this affects linux usability and stability.

I had this earlier but the problem still existed.
