** Description changed: This is a followup of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1501260 . Basically, running OpenGL applications (e.g. glxgears) on the primary display handled by Intel 915 card results in display freeze. The error message from the title of this bug is written to a VT console if I switch to it. It seems this bug only appears when multiple monitors are connected. Switching to a VT (Ctrl+Alt+F1) and back unfreezes the screen for a while. The screen only looks frozen, but normally reacts to mouse and keyboard events. This only happens if the GL window is displayed on my primary display (which is handled by the intel integrated chip). The notebook has 2 video outputs and a discrete AMD graphics, and I think only one of the outputs is handled by the AMD card, so I think one of the outputs is handled by the intel card and does not get frozen. Ubuntu 14.04.3 64bit. I think that before upgrading from 14.04.2 to 14.04.3 this did not happen.
