But I can't understand, why generic ubuntu kernel allow normal work of Unity 3D for normal users without video group =) Btw, I already writes before: I have only one explanation: "Mesa DRI Intel(R) G33 x86/MMX/SSE2" can't access to something because of limited privileges of simple non-root user. But looks like I was too stupid for checking standard groups of my user. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1071482 Title: [dri] Normal non-root user does not have permissions to use the GPU (falls back to LLVMpipe) Status in “mesa” package in Ubuntu: New Status in “xserver-xorg-video-intel” package in Ubuntu: New Bug description: Running as a normal non-root user the system is falling back to LLVMpipe software rendering, which then triggers graphics corruption (bug 1021104).

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.
