I have a problem with my screen resolution after I upgraded from Ubuntu 13.04 to Ubuntu 13.10.
My computer: HP ProBook 4720s :: Intel® Core™ i7 CPU M 640 @ 2.80GHz × 4 :: 64-bit
In System settings -> Displays:
The screen resolution seems stuck on "Built-in Display resolution 1600x900 (16:9)". I cannot change to any other resolution neither on my laptop screen nor when I connect to my external monitor. "Detect displays" doesn't work.
Here is a screenshot: https://drive.google.com/file/d/0Bw6...it?usp=sharing
When I connect my external monitor, I see black stripes on the side. The resolution is incorrect: https://drive.google.com/file/d/0Bw6...it?usp=sharing
I removed AMD Legacy drivers as described here: http://askubuntu.com/questions/363255/lubuntu-13-10-amd-ati-radeon-laptop-screen-is-black-after-upgrade-from-13-04
Here is the output from glxinfo:
