mikhail,
It looks like a simple permission problem making you fall back to
LLVMpipe when not root. I think you need to be in the "video" group to
access the graphics hardware but are not (and I have no idea how or why
that would happen).
I'm not sure what the relevant device name is for you but a good guess might be
to try:
sudo chmod 666 /dev/dri/*
Log out and in again.
** Summary changed:
- everything is black and blinks (flashes) when using unity
+ [dri] Normal non-root user does not have permissions to use the GPU (falls
back to LLVMpipe)
** This bug is no longer a duplicate of bug 1021104
Severe damage artefacts and flickering when using LLVMpipe
** Package changed: unity (Ubuntu) => xserver-xorg-video-intel (Ubuntu)
** Changed in: xserver-xorg-video-intel (Ubuntu)
Status: Incomplete => Triaged
** Description changed:
+ Running as a normal non-root user the system is falling back to LLVMpipe
software rendering, which then triggers graphics corruption (bug 1021104).
+ OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x300)
+
+ Logging in as root however, full GPU acceleration works and Mesa uses:
+ OpenGL renderer string: Mesa DRI Intel(R) G33 x86/MMX/SSE2
+
+ ORIGINAL DESCRIPTION:
I am using Ubuntu Precise 12.04 LTS with last updates (25.10.2012) from
precise, precise-security, precise-updates, precise-proposed. My bug is some
similar for https://bugs.launchpad.net/ubuntu/+source/unity/+bug/819144
But I have not fglrx.

Xorg uses standard "intel" driver. Same result with using "vesa" driver
(with vesa I always have disappearing mouse cursor on tooltip showing,
even without unity and compiz). Unity_2D works fine of course.
I will try to explain behavior of this bug...
1) Unity panel and upper panel renders (shows picture) fine.
2) Other desktop space often blinking (they replace each other) by 3 types of
picture:
a) simple black
b) some previous state of picture (ghost picture): I mean e.g. if you close
some window, you will still can see this window with buttons, which already are
not clickable of course.
c) current picture
3) If you move mouse cursor over desktop icons (I have many icons), it
sometimes cleans rectangles with icons, sometimes not.
4) If you move some window by mouse, part of desktop can be cleaned by
previouse position of this window and all positions while window moving. This
cleaning type is not always works too.
4) If you switches between consoles (Ctrl+Alt+F1, ..., Ctrl+Alt+F7), desktop
starts blinking as in "2)" and sometimes it stops on cleaned good desktop,
sometimes on black desktop (black except left and upper panel of cource).
5) Sometimes (e.g. while pressing Ctrl+Alt+F(1-6) and back to Ctrl+Alt+F7) I
can see thin lines of some picture (from actual or previous state of window, I
can't understand which) on black desktop.
I tryed to install different stable versions of unity and compiz (and
associated packages) with no success.
I tryed to install fresh drivers from
https://launchpad.net/~ubuntu-x-swat/+archive/x-updates with no success.
I rebooting my computer after each time of changing unity/compiz/drivers
packages.
After some time (of installation of different packages) unity start to
work normally (without black blinking) but for root only! I don't want
to be root all time which I using unity. Please, help.
Update 1:
Immediatly after login unity left panel can replaced by black too (not
always), but it's returned to normally after moving mouse over it.
I created new user to test behaviour under it. Same result: black and other
blinking.
Guest session is with black blinking too.
Update 2:
I have not anything like unclutter, synergy and quicksynergy.
Maybe this helps:
