Hello, If I boot my system with a HDMI cable plugged in, the system hangs. Yours does not. It might be a BIOS setting, or different software. The only thing active at that time is grub. However your bios might be initializing HDMI displays?
The xorg package you mention is a fairly high level component common to all drivers. I downloaded its source and it does not contain the Intel source files found at http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/ What I would really like is the output of the command: $ dpkg-query -l xserver-xorg-video-intel unless the names of the low level X11 device driver packages have changed. My glxgears figures were much lower, about 60 percent of yours, until I removed the compiz-settings-manager package command ccsm->utility->workarounds-> "force full screen redraws on repaint" setting, in which case my figures were on or about yours. Because I like my dvd's un-torn, I reset the setting. (NB I got this tip from somewhere on the net). Benchmarks from my system. 1) Compiz full screen redraws set. $ optirun glxgears 1824 frames in 5.0 seconds = 364.391 FPS 1672 frames in 5.0 seconds = 334.263 FPS 1629 frames in 5.0 seconds = 325.675 FPS 1627 frames in 5.0 seconds = 325.275 FPS 1633 frames in 5.0 seconds = 326.568 FPS 1824 frames in 5.0 seconds = 364.265 FPS $ optirun glxspheres Polygons in scene: 62464 Visual ID of window: 0x21 Context is Direct OpenGL Renderer: GeForce GT 540M/PCIe/SSE2 129.562550 frames/sec - 144.591805 Mpixels/sec 127.488875 frames/sec - 142.277585 Mpixels/sec 131.088293 frames/sec - 146.294535 Mpixels/sec 136.656429 frames/sec - 152.508575 Mpixels/sec 132.135017 frames/sec - 147.462679 Mpixels/sec 131.454289 frames/sec - 146.702986 Mpixels/sec 132.897055 frames/sec - 148.313113 Mpixels/sec 131.981073 frames/sec - 147.290877 Mpixels/sec 134.434321 frames/sec - 150.028702 Mpixels/sec 134.227708 frames/sec - 149.798122 Mpixels/sec 2) Compiz full screen redraws unset. $ optirun glxgears 2837 frames in 5.0 seconds = 567.161 FPS 2437 frames in 5.0 seconds = 487.216 FPS 2496 frames in 5.0 seconds = 499.056 FPS 2580 frames in 5.0 seconds = 515.894 FPS 2442 frames in 5.0 seconds = 488.062 FPS 2551 frames in 5.0 seconds = 510.015 FPS 2354 frames in 5.0 seconds = 470.678 FPS 2496 frames in 5.0 seconds = 499.110 FPS 2803 frames in 5.0 seconds = 560.427 FPS $ optirun glxspheres 134.945369 frames/sec - 150.599032 Mpixels/sec 139.204486 frames/sec - 155.352206 Mpixels/sec 138.760033 frames/sec - 154.856196 Mpixels/sec 136.760540 frames/sec - 152.624762 Mpixels/sec 135.488611 frames/sec - 151.205290 Mpixels/sec 139.077046 frames/sec - 155.209983 Mpixels/sec 136.160370 frames/sec - 151.954973 Mpixels/sec 140.133521 frames/sec - 156.389009 Mpixels/sec Obviously the decrease in performance by applying the setting is much less with glxspheres than with glxgears, probably because of the higher framerate. I can live with the lower framerate, but not the video rips. I was going to try different versions of the intel X11 driver, but perhaps the bios might be more productive. If you could find any version information on that, would be great.
