Since my last update

[James Morrissey]

Hi,

Since my last update a number of things have stopped working.

1. Brightness controls no longer work (fn+F8 and fn+F9)
2. Only skip forward works (fn+F12), skip backwards (fn+F10) no longer does
3. Suspend on lid-close appears to have stopped working - the box is
checked in my power preferences
4. Fan appears to have stopped working.

I am using the Gnome 3 desktop and running a thinkpadx121e.

Does anyone know how i go about finding out what's causing the
problem, or how i can fix it?

Thanks,

j

You don't say what version of Ubuntu you're using. Was it an update between versions, our just a daily/monthly update within a version?

Neil.

P.S. Sorry for the brevity, this is typed on my phone.

sorry, of course.

I am using 11.10. It was just a daily update.

Try installing (or reinstalling) tpb,  it's in the Software Centre or can be installed using apt-get install tpb.

Installed tpb and restarted, but to no avail.

Any other ideas?

This recently stopped working for me as well, although I'm using Precise.

Still no luck on this however after googling acpi related problems in
ubuntu i saw references to kernel panic. I then remebered that i had
seen a paniclog file in my home folder.

The file's contents are: 0.0.7E7F3 20120303: impossible Read from
proxy interface failed

That is all.

If this sheds any light on this issue, i'd love to hear thoughts.

And today, everything works again!

Don't know what could have caused this. The only major difference is
that i am now working in an air-conditioned room and no longer in 35
deg heat and 90% humidity - which was driving my CPU temp through the
roof, esp with the fan problems.

Could the temperature have cased these problems? I ask as i'd like to
file a bg if thats the case.

It is very possible that temperature is the problem. It's not a bug though, it's a hardware issue.

Ok, that's good to know. It is a bit frustrating if high temperatures
break the fan...

James,

Your cooling may not be broken, it may be that the heat exchanger matrix
on your CPU is blocked with dust and fluff from your home furnishings. A
quick check would be to use your vacuum clearer to clean the heat
exchanger by sucking 'the wrong way' through the matrix. I regularly
have to clean the matrix on my home desktop PC. My understanding is that
a machine with a hot CPU will reduce the operating frequency of the CPU
to reduce the heat generated. This will impact on the available
performance of the CPU and may be source of the reports of your CPU
using 100% of its available performance to do basic operations, because
its maximum available performance is greatly reduced.

OK, thanks for the tip. I'll give it a try when i next get close to a
vacuum cleaner.

Air-dusters work better, IMHO, & have less risk of static discharge.
Maplin's are a cheaper source than PC World & Poundland (when they
have them) a much cheaper source than Maplin's.

To really get the crud out of a heatsink, though, tends to require
removal of the fans, and possibly removal of the heatsink from the CPU
& consequent removal of the old TIM compound and replacement with
fresh TIM.

None of this is hard, but it's a bit fiddly.

On this issue, it played up again, with the fan problems meaning the
machine was getting way too hot. So i sent it back to Lenovo who
cleaned everything out and replaced both the keyboard and fan. All
under warranty so no cost - other than the 10 days without my machine.

Everything is working now with the machine running cool.

Keep it away from the bed clothes / quilt! My current piglet (unix name of my laptop)  was passed on to me as a system that over-heated within a couple of minutes. The judicious use of a commercial vacuum cleaner with small nozzle attached sorted that problem out :) As the 'muck' is sucked into the macine, simply sucking on the import side of the fan (the outside) sorted it out. For desktop systems, the 'muck' can get into your CPU fan etc, but laptops tend to use a heat-sink to the central fan. At least, that has been my experience with laptops.

Regards,

Phill.
