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

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.

Much thanks,
Peter Garrone
