The Gazebo robotics simulation is working very slowly on my Thinkpad X220 with Intel graphics and this is probably due to the same problem. Ubuntu version is 12.04.
As pointed out to me, the important information here is in glxinfo (full info attached) : "client glx vendor string: Mesa Project and SGI" Kernel version 3.2.0-34-generic is no better, I have done dist-upgrade and tried reinstalling mesa-utils. This bug seems to affect many people and in my case, it affects very badly my work progress. Unfortunately the tools I need to use are tied to a specific Ubuntu version. ** Attachment added: "glxinfot.txt" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/999493/+attachment/3479054/+files/glxinfot.txt -- 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/999493 Title: Intel graphics drivers slow off-screen rendering in Precise Pangolin Status in “xserver-xorg-video-intel” package in Ubuntu: Confirmed Bug description: I have a robotics application built on top of the OGRE3D rendering system that works fine on a wide range of machines running Lucid. When I switch to Precise, it runs so slowly on machines with Intel integrated graphics that it's unusable. But it's fine on machines that use non-Intel graphics (I tried a Dell Optiplex 755 with an ATI RV610 card, which under Precise uses the Gallium 0.4 driver.) I'm reporting this bug using an ASUS Eee PC 1015 netbook; with Precise it uses the Intel IGD driver. I'm seeing the same problem on a Lenovo Thinkpad X220, which uses the Intel Sandybridge Mobile driver. To try to quantify the performance hit, I ran glxgears on the ASUS. Under Lucid it reports 300 fps. Under Precise the same machine is getting 59 fps. That's a 5x slowdown. The Lenovo is getting 60 fps under Precise. One more piece of info: my application runs fine on the ASUS and Lenovo machines when I don't request off-screen rendering. If I'm only rendering to the display, I can pan and zoom around in my virtual world quickly and smoothly. But as soon as my robot client connects and starts requesting off-screen rendering (simulated images for the robot's camera), the performance falls apart and the application becomes unusable. If I kill the client, which disables off-screen rendering, performance returns to normal.
