@Bilal, note that the i915 you're seeing in your lspci is the kernel driver, not the chipset family. For instance on my system it is:
$ lspci -vvnn ... 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 945GSE Express Integrated Graphics Controller [8086:27ae] (rev 03) (prog-if 00 [VGA controller]) Subsystem: Dell Device [1028:02f4] .... Kernel driver in use: i915 Kernel modules: intelfb, i915 For some intel devices they don't give the chipset family, but you can look them up using the new xpci command: $ xpci 8086:27ae i945gme (8086:27ae|945GME) i945 xserver-xorg-video-intel -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/981168 Title: Regression: Installing apps causes a terrible visual glitch-- have to restart X.org.
