[Bug 343108] Re: [jaunty] [i915] After last update my desktop started to blink very often

[Carey Underwood]

Divius, can you attach the output of lspci -vvnn?

** Description changed:

- After previous update after reboot I encounter very strange behavior of my desktop.
- There're 2 things:
- 1) Just after starting gnome mouse starts to jump up and down, avant window navigator and gnome-panel stops loading in the middle of the process; only ctrl+alt+backspace helps;
- 2) While working with some programs (encountered with QDevelop and Synaptic, not encountered with Firefox) screen suddenly starts to blink, widgets of the started program become to appear in different parts of the screen. Changing to another application won't solve the problem no matter what application.

- I've tried to revert compiz from ubuntu3 to previous ubuntu1 version but in vain.
- I have no idea about what is happening but it prevents me from working.
