Hi,
For about a week now my laptop (ubuntu 10.04 LTS fully updated) has
been freezing up for approx 30 secs, with gkrellm and top showing
xorg using 100% cpu usage?
There seems to be no pattern to what programs I am using, everything
from open office to clementine to smplayer or thunderbird, not at
any certain time of day or day of the week, or even weather using
the inbuilt screen or external one.
My understanding (admittedly limited) is that xorg is the bit that
works the display (screen). Has anyone else come across this?
For reference the laptop specs are:
Acer Aspire 5720
Intel T5250 Dual core processor
Ram 2.0 gb
Internal graphics (intel)
Internal sound (intel)
Thanks in advance for any ideas
Regards
Pete
just for reference my xorg.conf:
Section "Device"
Identifier "Configured Video Device"
Driver "fbdev"
EndSection
Might want to look into that bit.
You should have a specific Xorg "driver" for your onboard Intel
graphics chip.
Run the following command to find out your graphics chip:
lspci
Look for the line that has VGA on it.
If it does indeed say something about an Intel chip, then make sure you
have the following package installed:
xserver-xorg-video-intel
(That package deals with all i8xx and i9xx chips)
Once that's installed, remove the xorg.conf file and restart X.
You can restart X by going to a terminal (NOT a terminal window...
press CTRL+ALT+F2 and log in) and then run:
sudo service lightdm restart
(Or just reboot... up to you.)

Hi Grant,
Thanks for your reply, the lspci command produces (relevant lines only I
hope)
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller (rev 03)
Synaptic shows xserver-xorg-video-intel is installed (reinstalled for
good measure) moved the xorg.conf file to my documents folder and
rebooted, opened t-bird to reply to you and the machine 'greyed out' for
approx 20 secs with gkrellm showing xorg as using 100% CPU! Please note
that last time it happened was with clementine running, when playback
stopped mid song so I cannot blame t-bird!
As an aside but possibly related?! when I open a tty shell (ctrl-alt-f1)
log in it tells me 'Your CPU appears to be lacking expected security
protections. Please check your BIOS settings, for more information
please run /usr/bin/check-bios-nx --verbose which produces
smouty@smouty-laptop:~$ /usr/bin/check-bios-nx --verbose
This CPU is family 6, model 15, and has NX capabilities but is unable to
use these protective features because the BIOS is configured to disable
the capability. Please enable this in your BIOS. For more details, see:
https://wiki.ubuntu.com/Security/CPUFeatures
I am unable to find any related settings in BIOS, if this is unrelated
to my original question please ignore it and I will do further research
Regards
Pete
