HDMI port not detected on laptop with ATI Mobility Radeon HD 5470

Hi All,

A while ago I bought a HP G62-b07SL laptop (

It has an ATI Mobility Radeon HD 5470 with an external VGA and HDMI ports.

What i want to do is using an external monitor connected trough the HDMI (NOT the VGA, as I need the VGA on the monitor to be connected to something else).

I can connect an external monitor to the VGA and it works fine but there is nothing I can do about the HDMI.
Ubuntu does not want to see it (note: the HDMI port works fine on Windows7).

Since Ubuntu 12.04 came out last Thursday I've been playing with it non stop with no success at all (how frustrating!).
I've done all my attempts/experiments with the monitor connected trough the HDMI (obviosly) and I noticed that, with the Radeon drivers, during boot and just before the computer goes off I can see the Ubuntu logo on the external monitor.
When the computer is on though, there is no sign of that monitor or the HDMI port at all.

With the external monitor connected (and set up the way I want it) trough the VGA I get:
xrandr -q
Screen 0: minimum 320 x 200, current 1920 x 1848, maximum 8192 x 8192

640x480 72.8 75.0 66.7 60.0
720x400 70.1

As you can see the HDMI port is not even mentioned.

I've also tried to enable the closed source drivers (fglrx) trough the Ubuntu "Additional drivers" with or without the "post-release updates" option (which I don't even know what it means) but they both failed with an error message and the Catalyst administration GUI fails to launch all the time (don't remember the precise error).

I tried then to install the same drivers (fglrx) with the manual procedure you can find here: but that one fails too and the error log (/var/lib/dkms/fglrx/8.961/build/make.log) says:
"DKMS make.log for fglrx-8.961 for kernel 3.2.0-24-generic-pae (i686)

make: *** [kmod_build] Error 2

To be honest, I'd rather use the open source driver but at the moment fixing the problem no matter what has priority.

So, if anyone has suggestions on what might be the cause, how to debug it or even how to fix it please don't be shy and give me a shout! :-P
Can't wait to hear from you! :-)

Thanks in advance,

As mentioned earlier, the fact that I can see the Ubuntu logo on boot (on the external monitor connected trough HDMI) gives me the impressions that the OS can actually see that monitor... but then something happens and it's not available anymore...

I've attached the complete "dmesg" after having just booted the pc.

Here instead is only some of it:

I'd be curious to know if anyone can spot anything suspicious here.

Ok, I have re-installed Ubuntu 12.04 64 bit from scratch and done other experiments with the proprietary driver.

The error mentioned earlier that I get when installing the fglrx driver trough the Ubuntu user friendly GUI (called "hardware drivers" or something like that) is:
"There was a problem initializing Catalyst Control Center Linux edition. It could be caused by the following.

No AMD graphics driver is installed, or the AMD driver is not functioning properly.
Please install the AMD driver appropriate for you AMD hardware, or configure using aticonfig."

A very generic error as you can see.
I've been told to look into the jockey.log error log (you can find it attached) and I did but I couldn't figure out much...

At the end, I've also tried with the manual method ( and my system restarted in low-graphics mode... :-/

As far as I know, the HDMI ports are not supported with the open source radeon driver with 5XXX Mobility cards yet.

The kernel used in 12.04 (kernel 3.2) wont work with the closed source ATI/AMD drivers without a patch-

I see. So basically the open source driver (radeon) are not what I'm looking for (unfortunately)... Now I need to understand how to install the closed source. :-/

I read somewhere this problem should effect the 32 bit only (I didn't look too much into it yet though).

AMD releases a new version of the Catalyst drivers every month ( so I'm HOPING they fix this in next release.

When they announced the new driver 12.4 ( they mentioned "This release of AMD Catalyst™ Linux introduces support for the following new operating systems
Ubuntu 12.04 early look support". Hope they will have a deeper look for the next driver release... :-)

Here the latest AMD drivers:
Quite interesting the "release notes" on that same page.

I'll continue my research later/tomorrow.

Thanks for the tips cascade9

After checking around, it looks like jockey (the 'hardware drivers' tool) should work with supported ATI/AMD GPUs and 12.04. 12.04 should have catalyst 12.4 beta.

Try updating before you get the drivers.

Well, my system is all up to date and is also a fresh install (I keep a small partition only for this problem).

The jockey version I have installed is the current stable release "jockey-gtk 0.9.7-0ubuntu7".

Another thing is not 100% clear to me; what's the difference between
"ATI/AMD proprietary FGLRX graphics driver" and
"ATI/AMD proprietary FGLRX graphics driver (post-release updates)"?

I think I understand what "post-release updates" mean but which one should I install?!? Anyone in particular?
Either of them in the hope that one day it will work? :-/

The post-release updates should in theory mean that it will install the same drivers as the regular install, but will update them whenever a new version of FGLRX is issued. Unfortunately, that option has never worked (for me at least, and as far as I googled, for others too).
So stick to the non "post-release updates" option.
Also, that means that Canonical "sort of" supports the reglar FGLRX (non "post-release updates") which was the latest version at the time the ubuntu version came out. By "sort of" I mean they can't actually fix the driver itself, but they allegedly made sure it works with the current ubuntu and further updates.

Thanks cheese1343 for the explanation.

I'm not sure who is responsible (Canonical, AMD/Intel or whoever else) but, in this case, they didn't manage to make sure that the whole "package" worked out of the box... :-D
