I have a brand new HP Desktop PC (Pavilion Elite HPE-557de).

I have tried to install some versions of Ubuntu (10.10, 11.04, 11.10 Beta 2) for 2 days, and every time GNOME is started, after 2-3 minutes of work Ubuntu freezes. After a hard restart it comes the same problem.

I gave the PC to one PC expert, who has installed 5 different Linux distributions and also is coming the same problem. Every time Linux is started, then it freezes.

My question is, is it possible that the on-board graphics card is not disabled, and it is doing this freezing stuff? HP says that "Integrated video is not available if a graphics card is installed", but is there a possibility, that this is not the case?

How can I see which card is loaded?

What graphics card does your system use? It sounds to me like you are getting a problem that usually occurs when Kernel mode setting is enabled with some open source drivers. – RolandiXor Oct 6 '11 at 18:10
It is an AMD Radeon HD 6850 ... like in the description of the PC, when you click on the link. – Niko Nik Oct 6 '11 at 18:11
it's better if you mention that directly in your question. We cannot be sure that you kept the same graphics card that came with the system, unless we are God himself. – RolandiXor Oct 6 '11 at 18:56
This question should instead be filed as a bug report, and as such is off-topic, thanks! Instructions here. – James Feb 3 '12 at 0:00

What does your /etc/X11/xorg.congf look like and what does this produce:


If you haven't added the additional proprietary driver for your card, its easy to check by running the following commands in terminal

sudo su cat /sys/kernel/debug/vgaswitcheroo/switch

the fglrx proprietary driver takes this away. so if you install a fresh system etc, see the output. It gives an output like-


1:DIS: :Off:0000:01:00.0

IGD = integrated graphics, DIS = discrete graphics, on an HP it might show both as powered, and the '+' sign will show which one is in use.
