TL;DR Version
I'm looking for a simple way to install a working graphics driver for my laptop (via command line or system settings) so that I can control the brightness and resolution.
Solution
Upgraded to 12.04 and followed instructions here: https://askubuntu.com/a/126549/46766. No special driver needed.
Additional Detail
I have an HP Pavilion g7-1310us laptop with this integrated graphics processor I bought a few months ago. I have installed Ubuntu 11.10. But I have never got the display working properly. Some specific symptoms:
- Display settings list "Unknown"
- Cannot dim screen with control keys
- No drivers listed under Additional Drivers
I have found a few questions related to this graphics card but none of these help me resolved my problem:
- ATI 6470m & intel HD graphics 3000 drivers?
- Intel HD 3000 (Sandy Bridge) 3d games problem
- https://askubuntu.com/q/114594/46766
Specifically, I just want to be able to control the screen brightness and perhaps adjust the resolution. I see that Intel lists a Linux driver released on 2012/04/23 on their download site: downloadcenter.intel.com. But it recommends "obtaining precompiled driver packages from your Linux distribution vendor".
I'd like to install either though a simple command line command or through the Additional Drivers window under System Settings.
Is this possible in either 11.10 or, if I upgrade, 12.04?
Thanks.
Intel HD Graphics 3000 works perfectly on my Lenovo T520; recognized automatically, all resolutions available, Unity (3D) enabled; no need to install any additional drivers (in fact, that option lists nothing in System Settings).
I strongly recommending upgrading to 12.04, because it gives you a newer kernel and a lot of the basic graphics driver functionality is incorporated into the kernel these days.
As for the screen brightness keys, that is not a function of the graphics driver but rather ACPI (the mechanism for controlling power); that is also primarily supported through kernel (modules), so upgrading should give you a higher chance of that working too.
Once you upgrade, please post a new question about any little problems that may remain, and we can try to help you out.
