XFCE screen rotate only choice normal

It is this problem only for non-free driver, or both drivers free and non-free?

AFAIK the Intel drivers are open source, there is no 'non-free' version

Thank you for your responses. I decided to buy an inexpensive card from NVIDIA and this solve the problem.

If I were you, I would first try with Debian Jessie to see if it is solved there -- it takes 10 minutes

You can download a Debian 'Live CD' from here (choose 'debian-live-8.3.0-i386-mate-desktop.iso' from the list). This will allow you to test without touching what you already have.

Choose 'Live (686-pae)' from the menu.


If it works, then it is probably worth going for it.
(LinuxCNC uses the RTAI kernel, not the one from Debian, but the version are about the same)

Going to NVIDIA might be a solution as well, but it also may screw up your latency -- from what I have read in this forum, NVIDIA cards are not always good candidates for low latency.

It works, what can I do?
