intel_do_flush_locked in Ubuntu 13.04/13.10

SRang2 · ‎10-24-2013

I've been working on setting up a NUC (DC53427HYE) with Ubuntu 13.04 and testing our in-house OpenGL (Jogamp/Java) application suite and I get the following error as the application crashes during the first frame rendering:

intel_do_flush_locked: No such file or directory

I have updated Ubuntu to 13.10, tried installing the 1.0.2 Intel graphics drivers from the Intel website, nothing has worked. I've tried these on another NUC running Windows 8 and had no issues. Also, I uninstalled the hardware driver packages and using only Mesa software drivers, my demos worked as intended (though very slow).

The thread including jogl logs can be found at the jogamp forum at: http://forum.jogamp.org/intel-do-flush-locked-No-such-file-or-directory-td4030343.html http://forum.jogamp.org/intel-do-flush-locked-No-such-file-or-directory-td4030343.html

Any help would be appreciated.

Hi sanosuke001,

The support for the drivers we have is for Windows only at this point. You may refer to the following page for more information about the Linux Drivers:

Then why do you have linux drivers for your Intel HD 4000 (the graphics chip in the i5-3427U in the DC53427HYE)? How is it different than the one in the NUC itself?

Regardless, any idea why that error message would be displayed? What it means? Maybe I can debug whatever is causing it with more detailed information and work around it.

Also, a bug report was posted on the jogamp Bugzilla page as a record of this ongoing issue

Hi sanosuke001

I understand but at this point there are no Linux drivers for your graphics controller from our side. I recommend you checking the Linux community in order to get the driver from the developers from that site.
