Does the output of ls -l /dev/dri/ change when docking? If not, does LIBGL_DEBUG=verbose glxinfo 2>&1 >/dev/null give any indication why it's suddenly using swrast_dri.so instead of r600_dri.so? It looks like udev misconfiguration. Thanks. |

Created attachment 34596 [details] dmesg, xrandr --verbose, glxinfo and Xorg.0.log before and after attaching to dock station Hardware: Thinkpad T400 with AMD Mobility Radeon HD 3470 If I start Xorg when my laptop doen't connected to dockstation 3D acceleration works fine: $ glxinfo | grep "renderer string" OpenGL renderer string: Mesa DRI R600 (RV620 95C4) 20090101 x86/MMX/SSE2 TCL DRI2 But if I start Xorg when the laptop connected to dock station or attach it to dockstation it falls back to software rasterizer: $ glxinfo | grep "renderer string" OpenGL renderer string: Software Rasterizer I use 2.6.34-rc3 + lastest drm/drm-linus (d668046c1).
