Fan full speed on Dell D630C After Upgrade 8.04 to 8.10 Beta

[Tim]

Hi,

After a upgrade from 8.04 to 8.10 everything works great except my fan keeps spinning full speed.

problem: Fan runs full speed for 4 seconds, then stops 1 sec en repeats 4 seconds full speed etc.

Running on Ubuntu 8.10 with kernel 2.6.27-7-generic, gnome 2.24.0
Downloaded the latest bug fixes.

I'm having a DELL Latitude D630C i have attached the lshw output. If you need more let me know.

Tonight i formatted and installed the ubuntu 8.10 beta from CD instead of the upgrade 8.04 to 8.10 i done 2 days ago. Fan seems to be controlled how it should be...

Going to install more packages what i used in my ubuntu 8.04 to see if i can get the same problem back. Right now i have default Ubuntu 8.10 beta, so no candy like compiz etc.

If i cant get the problem issue back i'm going to install Ubuntu hardy 8.04 again and doing the upgrade again to see if the problem is coming back.

To be continued....

Hi all,

Yesterday i tried to reproduce the problem with a clean installation of Ubuntu 8.10 Beta. After installing all the packages still no problem with the Fan. so i tried something else:

Installed ubuntu 8.04 (latest packages /updates) then upgrade to 8.10 beta, problem is back. Fan goings spinning full speed and after a while it goes in a sequence (4 sec full speed - 1 sec stop). Today i tried to see what is different and where the problem can be.. I noticed a NVIDIA driver 177.80-0Ubuntu2, in Ubuntu 8.10 by default? I downgraded this driver to:
173.14.12-1-0Ubuntu4 and the problem is gone.

Formatted my laptop again. Installed ubuntu 8.10 beta downloaded latest upgrades, installed nvidia 177.80-0Ubuntu2 and the problem is back again. Downgraded again and the problem is gone.

Thought this can be some help in solving the issue.

So, dont know if the problem is in the nvidia driver, or Ubuntu having problems with the driver. But something there is going wrong ;).

ps, sorry for the type/spell mistakes...

thanx tim for all your efforts, that was some excellent debugging you did!!!

[Dimitrios Symeonidis (azimout)]

summary: it seems like the 177 nvidia driver might be overheating the graphics chip, causing almost-continuous fan activity, while the 173 driver doesn't... i will do a search for duplicates now...
