Comment 5 for bug 683901

Hello! :-) It's great to hear a person with exactly the same laptop and problems as I have.

It is strange that pavucontrol solved the problem in Ubuntu 10.10 and is not able to do it again in 11.04. I will probably digg a little bit more around it to try to get it fixed.

Regarding your temperature problem, I have never had such a problem with this laptop (or any other computer with Ubuntu installed) yet. However, I bought that laptop last Wednesday, so I don't own it even a week and during the installation it was connected to the Internet so it downloaded the most recent packages available. I searched on packages.ubuntu.com, read Ubuntu changelog for the kernel package and I have discovered that the kernel package has been updated several times in the Ubuntu 11.04 repository so if you had a problem with overheating in the past that could really be caused by the kernel, it is probably already fixed. I am not able to find the actual temperature of the processor in Ubuntu (I tried hardinfo but it doesn't show any temperature sensor) but using "aticonfig --odgt" I can show at least the temperature of the graphics card - and it is pretty low, right now when I have pidgin, evolution, firefox with many tabs and synaptic opened, it shows 45°C and the fan is almost inaudible. With a fulHD game it is still about 55°C.

Also, as I hated the Unity interface on my 17" workstation with 1280x1024 resolution and changed it after a few minutes to classic GNOME interface, I got used to it on the laptop's fullHD screen and now I can clearly say that I love the Unity interface that is really a time-saver, that is simple and that uses the Win logo button in the best way :-)

The only other problem except the audio that I have discovered regards the graphics. When I start a full screen game (full screen totem player and other normal programs work fine) it freezes the laptop and I have to restart it by keeping the power button pressed for a while and then turn it on again. A strange thing happens also with the hibernation to RAM (or maybe it concerns also hibernation to HDD, I haven't tired it yet) just by simply closing the laptop. According to the system log, it seems like the X server crashes and fglrx then crashes too I think (or in reverse order) - after opening the laptop again, I see the login screen as if I have just turned it on, so I log in and I am not able to use the Internet connection (neither wireless nor by a cable) and possibly a few other things. Also, the fglrx driver is not able to change the screen's brightness for some reason. I am using Catalyst 11.6 now, downgrading to 11.5 or the version from Ubuntu 11.04 repository didn't work, Catalyst 11.4 from AMD sites wasn't even installable.

Sorry for so long off thread message.
