Mesa 9.0 (quantal) uses LLVMpipe (slow) on ThinkPad L412. Mesa 9.1 solves it.

#803943 is marked as fixed, but it is not fixed.
With 12.10 and Intel HD Graphics the problem still persists

In idle phase compiz top show 80%-120% cpu and shows load between 1,2 and 2,2

Please do these:

Determine if the problem is Compiz or Unity (which runs inside compiz). You can do this by logging in to Gnome Classic (install gnome-session-fallback) and see if the problem persists. Alternatively, open some terminal windows, one running top, and in the other run ccsm, click on the Unity plugin and untick it to disable it temporarily. Does the CPU go down when just unity is removed? Remember to tick it again to enable Unity before logging in again.

Secondly, please collect stack information:
1. Copy the attached script to your home directory
2. Open a terminal (Ctrl+Alt+T)
3. Run: sudo sh ./dstack compiz >> compizcpu.txt
4. Repeat #3 many times.
5. Attach "compizcpu.txt" to this bug.

Hi Daniel,

thank you for your answer.

I installed gnome-session-fallback, and yes there is a difference.

With Unity top shows about 80%-120% CPU and the Load Index between 0,8 and 1,8.

The i switched from Unity to Gnome Classic with effects (not Gnome Classic 2D).
Top shows between 8% and 15% CPU and a Load Index between 0,1 and 0,3.

This night i will start your dstack Script every 10 second for a minimum of 8 hours and leave the laptop untouched.
Hope, thats ok for you.

Best regards
Joerg

One thing is clear in the logs that you do not have the necessary hardware acceleration to run Unity so its LLVMpipe related.

[Daniel van Vugt (vanvugt)]

That's surprising. It looks like a new-ish machine.

jmalter - Please run this command (from Gnome Classic) to confirm:
     /usr/lib/nux/unity_support_test -p
What does it show?

[jmalter (joerg4711)]

It shows:

OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301)
OpenGL version string: 2.1 Mesa 9.0

Not software rendered: no
Not blacklisted: yes
GLX fbconfig: yes
GLX texture from pixmap: yes
GL npot or rect textures: yes
GL vertex program: yes
GL fragment program: yes
GL vertex buffer object: yes
GL framebuffer object: yes
GL version is 1.4+: yes

Unity 3D supported: no

[jmalter (joerg4711)]

Attached you will find the requested file

[Daniel van Vugt (vanvugt)]

Thanks, that just confirms this is a duplicate of bug 1055936.

[jmalter (joerg4711)]

@Daniel

I solved my problem right now.

/usr/lib/nux/unity_support_test -p

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile
OpenGL version string: 2.1 Mesa 9.1-devel

Not software rendered: yes
Not blacklisted: yes
GLX fbconfig: yes
GLX texture from pixmap: yes
GL npot or rect textures: yes
GL vertex program: yes
GL fragment program: yes
GL vertex buffer object: yes
GL framebuffer object: yes
GL version is 1.4+: yes

Unity 3D supported: yes

What i have done is:

apt-add-repository ppa:xorg-edgers/ppa
apt-get update
apt-get upgrade

This will install the newest Intel Driver. As you can see 3D Support is now active.

[jmalter (joerg4711)]

Top shows now for compiz about 2% cpu usage

[Daniel van Vugt (vanvugt)]

OK, so in summary:

Mesa 9.0 in quantal reports:
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301)
OpenGL version string: 2.1 Mesa 9.0
which makes Unity slow (bug 1055936).

However Mesa 9.1 reports:
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile
OpenGL version string: 2.1 Mesa 9.1-devel
and everything works nicely.

jmalter, thank you for reporting this and helping make Ubuntu better.

As per https://wiki.ubuntu.com/Releases, Ubuntu 12.10 reached EOL as of May 16, 2014.

Is this reproducible in a supported release?
