Has anyone installed correctly Ubuntu 12.04 on HP ProBook 4530s (Radeon HD 6490 M + Intel HD Graphics)?I don't have much time to spend in configurating the system,I would most like to simply install a system that works on my machine.I was tried this 4 months ago but I gave up because of a lot of trouble that I encountered. :(

Hybrid-graphics/dual-graphics involve some work on Linux and don't always work as well as they do in Windows. – izx Jul 26 '12 at 15:52

I have. The battery lasts about an hour and a half.

Video drivers should be installed by generating a ubuntu-specific package from the download from AMD (not by ubuntu's additional drivers).

Hibernation doesn't work (it works, see update).

Everything else works.

Update: The only thing I couldn't get to work were additional drivers for the Touchpad on/off led, and its multitouch features.

laptop-tools (package) and indicator-cpufreq increase your battery life, but not by much. I'm still working on that.

If battery life bothers you, you can read additional information here (there are great links in the answers and comments): Ubuntu 12.04 Battery problem and Is there ongoing work in the kernel team to improve battery life under linux?

indicator-cpufreq PPA (their instruction says not to use for Precise and above, but worked for me):

Also, hibernation works (it wasn't enabled by default or something).

To enable hibernation, type:

$ gksu gedit /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

And paste the following text into that file:

[Enable Hibernate]
