deffragHello! I've been noticing abnormal behavior in Ubuntu 12.04. My system's GUI and keyboard suddenly freezes but it doesn't freezes movement of mouse, audio playback and ssh access. I cannot click on anything, change to tty0-6, caps lock on/off gives no indication. I'm not able to understand this type of behavior. Can anyone help me identify the problems and fix them please?20:36
deffragI'm faced with the problem again and currently I'm connected to the problem system from netbook via ssh. I can see top/htop giving an also increase/decrease volume using alsamixer. I don't know how it sounds or what I'm missing here ...20:38
deffrag..I can see top/htop listing processes and can also increase/decrease... *20:39
deffragBut not able to get anything working directly on the problem system20:40
JanCdeffrag: does the screen still update (e.g. the clock)?20:56
deffragJanC: No, nothing really update.20:56
deffrags20:56
deffragClock is 40 minutes behind20:56
JanCno heavy swapping going on?20:58
deffragSec, let me give you mem info20:58
JanCalthough 40 minutes is long20:58
deffragSystem is still running as per top from ssh and I can only have cursor movement on the problem system20:59
JanCand most likely that would cause audio to stutter too20:59
JanCcould be a graphics driver issue...20:59
deffragNo, no distortion at all. The music is playing as if nothing happened21:00
JanCor in theory also a compositor (compiz) issue, I suppose21:00
deffragAnd the graphics card is disabled using bumblebee, as I'm using gfx with optimus21:00
JanCif this has anything to do with graphics, you probably better ask in #ubuntu-x (or on their mailing list)21:01
deffragI forgot how to fetch MemInfo and SwapInfo parameters form commandline, somewhere in /sys/proc if I;m right21:02
deffrag$ cat /proc/meminfo 21:03
deffragMemTotal:        6005648 kB21:03
deffragMemFree:          215700 kB21:03
deffragSwapTotal:       5235708 kB21:03
deffragSwapFree:        4849064 kB21:03
deffrag.. in reply to what you asked initially about swapping21:04
deffragIf that help. Thanks, I'll try asking in #ubuntu-x21:04
deffragJanC: With help from #bumblebee identified the issue to be very close to https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/101501521:34
ubot2Ubuntu bug 1015015 in xserver-xorg-video-intel "Xorg freezes once a day, mouse and SSH still works" [High,Incomplete]21:34
JanCdeffrag: certainly sounds like an issue for the X team then21:36
deffragYes, thank you21:36
