View Full Version : [ubuntu] nvidia change brightness freezes laptop

May 13th, 2011, 12:08 AM
I've just installed 11.04 on a lenovo w520 using nvidia quadro 1000m. I set the bios to use only discrete graphics.

I change brightness of the display the system freezes and needs a hard reboot. I had to set my power saving to always use 100% brightness or it crashes when I unplug the adapter.

Any solutions? Need a new version of X? A new version of the nvidia driver?

This is most likely related to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/776999 , I am having the same issue. If anyone can provide hints how to debug this, I will do the work :)
