Public bug reported:
I did a fresh install of 12.04 a couple of moth ago. Everything worked
fine. I did the usual update via update-manager 2 days or so ago, were
xorg packages were updated. Now when I do _anything_ xorg consumes
between 40% and 60% CPU and the whole system is very slow and laggy.
This happened after the reboot I did after updating. Maybe theres a
connection?
I'm using 12.04 with Gnome3. This is my graphiccontroller:
00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and
945GT Express Memory Controller Hub (rev 03)
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS,
943/940GML Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML
Express Integrated Graphics Controller (rev 03)
It's a Dell Laptop.
