Thread: OpenSuse 12.1 becomes unresponsive, but not hang

  1. #1

    Default OpenSuse 12.1 becomes unresponsive, but not hang

    Hello Everyone,

    I am running into this problem very often: Some of my applications' UI's become unresponsive, but the applications keep running fine. For instance, sometime the minimize, maximize and close buttons are unresponsive, but the application itself is running fine.

    Sometimes it happens when I am running flash application (Youtube), but then there are other times when its not about flash too. I do a "top" or "iotop" but I do not see anything strange.

    Also, I read that gnome 3 shell extensions may not be breezy. Is it a common experience?

    I have an Nvidia card, and all drivers are installed fine.

    My System: Linux #### 3.1.9-1.4-desktop #1 SMP PREEMPT Fri Jan 27 08:55:10 UTC 2012 (efb5ff4) x86_64 x86_64 x86_64 GNU/Linux

    Can someone suggest what to fix? Or where to look?

    Thanks a lot.

    Can I get you to post the kernel modules you have installed? I have a bash script that can help:

    S.K.I.M. - SuSE Kernel Installed Modules - A lsmod replacement- Creates Alphabetized Module Listing - Blogs - openSUSE Forums

    I would use the advanced message editor, post the text into a message, highlight it all and press the # code button to place in a code block. Lets see what you are running on that PC.

    Thank You,

    I hope I did the steps right as per your suggestion.

    Thanks a lot for your help!
    Hey you did great, just like I asked. I see that you must have a laptop, a Thinkpad perhaps. I was looking to see the nVIDIA driver is loaded and the nouveau driver is not, which matches up. I see you must have installed the btfs file system and perhaps it is encrypted. I consider btfs to still be experimental and along with encryption could be a source of slowdowns. I wonder what speed you are running your CPU at? I also ask how old is your laptop and if a year or so, have you ever blown out the CPU heat sinks of dust since you got the laptop? I have a couple of more utilities to share and you need to tell me a lot more about your hardware, its speed, its age and the about the disk partition types you install openSUSE in to?

    Hello jdmcdaniel3,

    My machine is pretty new, and I cleaned the heat-sinks, in fact the entire cooling system recently. I am fairly certain that the problem is not with cooling.

    I have a fairly new quad-core machine ( 4 x Intel(R) Core(TM) i7 CPU M 620 @ 2.67GHz) on a T410. I have 4GB RAM. The problems with responsiveness were not there in 11.4 version of OpenSuse.

    I do accept that this is the first time I have a Btrfs file system, as well as an encrypted partition. Most of the times this partition in not mounted. I am not sure whether or not to blame the Btrfs system for any slowdowns.

    The smolt hardware pointer did not seem to work, but with the HI output, I am not sure I need anything else. Of the many things listed, my main concern is free disk space. Looks to me like you are down to your last 15 % of space. I might ask that you open up terminal and issue the following commands:

    Code:
    su -
    password:
    fdisk -l
    free
    And post the output from these commands.

    It's my 5c tip and a wild guess at the same time but I bet the culprit is btrfs you use as fs... The pictures you provided do not show the mountpoints but one of them must be /home .

    Have a look at this thread and maybe some hints (Marguerite's bug report) on how to solve some (but not all) of the issues.

    I tend to believe that I am right since you mentioned flash - so actually a browser (firefox maybe) and the btrfs issue is related to the sync of its files (check the links in my last post in that thread).

    Cheers.

    Since support for btrfs keeps improving with each kernel release, its possible that upgrading to kernel 3.2.4, the latest stable kernel, might improve the operation of btrfs as well and might be worth a try.

    As per ghostintheruins' suggestion on suspecting btrfs, maybe he is right. Right now, I do not have any way of knowing it.

    And yes, my /home is on /sda2 and its almost full. I messed up my partitions during the OS install. I am considering a re-install, but I want to decide whether or not to user btrfs this time. It seems the consensus is that the technology is still new. However, I am not sure whether or not 4G free space is too low for Linux to work properly.

    Thanks a lot to both of you for your comments.

    Best

    Actually if you want to be sure if the btrfs is the culprit use iotop and see if the Btrfs-* related process will eat your CPU like in Marguerite's post.

    But since you are getting your partition full, fragmentation will hit you on btrfs and that is also when this freeze phenomena happens - check the links I recommended you to read - there will be hints on how to find and defrag your files too there.

    Also, if you're bold ( ) use jdmc's suggestion to compile a new kernel.

    Cheers.
