Noob here: System random hang. Running Opera and Pidgin

[moviezzz]

Hi all,

Noob here. I installed Ubuntu 12.04 but noticed it hung randomly a few times. A few apps would be opened, namely Opera and Pidgin. Appreciate help on solving this.

Hardware using is Dell E6320 with its default hardware specs.

Thanks in advance!

JJ

[lrcaballero]

Can you provide us with more specs of your system please.

[moviezzz]

hi..

Is there any command I can use to get these info?

JJ


Can you provide us with more specs of your system please.

If you open a terminal and leave 'top' running
Then open opera and pidgin
Bring your terminal back in to focus and watch to see the processes.

You can install something call hwinfo
It can fet a detailed list of all your hardware. But it's usually sufficient to just post the output of


lspci -nnkThat will tell us about most of the hardware and loaded drivers

[carl4926]

Nothing unusual in that output if you ask me
unning top may help you identify the issue
or check .xsession-errors

[moviezzz]

hi,

how do i check .xsession-errors?

I can't really pretend to understand all that, but perhaps someone will.

Pidgin is obviously having some kind of bad hair day.

But you mention Opera specifically. Does that mean that pidgin is OK with no opera and or with other browsers?

If you use fallback mode, do things work differently?

do you have swap?

This posted suggests he does

[moviezzz]

i have dual boot. windows 7 and ubuntu. is the problem here?

[moviezzz]

i dont know if one will function good without the other. sometimes the system doesnt hang the whole day, sometimes it hangs withing 1hour. i work with these 2 apps, so i cant really have one closed and wait for the problem since the problem is random.

Hi,

yes, i have swap ->

i installed my ubuntu alongside my windows 7 following the default install. changed nothing during the installation.

Hi,

I disabled flash in opera but system still hung. :(

[carl4926]

I don't see any hardware from the lspci output that would give me cause for concern.

Personally I think you need to try working with other options in software and see if the problem is solved (such as Chromium and Empathy), if it is...
Then I would consider reporting to Launchpad bugs your problem with opera/pidgin

[moviezzz]

hi Carl,

i did as u suggested, only chromium was opened. but it hung and then powered off by itself.

you have a second gen i5 without the lastest kernel

does your computer feel warm?

I have a fan pad attached so it's always not warm. Just touched everywhere it wasn't warm. It has been running for about 3hrs already.

it does not say the core temp

Did you follow all the direction in the sensors-detect

such as


sudo modprobe coretemp

i believe that should be the correct module, but i usually let the sensors-detect tell me

[moviezzz]

Do you mean this? :

Driver `coretemp':
* Chip `Intel digital thermal sensor' (confidence: 9)

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

Do you want to add these lines automatically to /etc/modules? (yes/NO)

i guess it is not a heating issue. If it is, i guess check the temperature, when it hangs, but i am not really sure what i going on

[moviezzz]

is there some kind of logs that will give me a clue? :(

donno

i might as well tell you to run commands to lower you computer running temperature


sudo bash -c 'echo "options i915 i915_enable_rc6=1 i915_enable_fbc=1 lvds_downclock=1" > /etc/modprobe.d/i915.conf'

if the screen resolution does not work then

add these to you grub parameters

acpi_osi=Linux apci_backlight=vendor

if you want to change you kernel scheduler to redunce cpu time


elevator=deadline
also add this to grub

[moviezzz]

Hi,

I did the 1st line to reduce the temperature:

sudo bash -c 'echo "options i915 i915_enable_rc6=1 i915_enable_fbc=1 lvds_downclock=1" > /etc/modprobe.d/i915.conf'

It didn't mess up the resolution, so do i still need to issue the 2nd and 3rd cmd?

Thanks for replying.

JJ
