Hello all,
I've got an Optiplex 745 with a build-in "Intel Q965/Q963 Express Chipset Family" videocard. On it I've written a OpenGL (3D) program. In certain circumstances the screen blanks and the 'puter locks up. The same program on another 'puter runs fine, even though it stutters a bit at the "certain circumstances" I mentioned (likely an indication of needing a bit more time to finish drawing the scene).
The only way /not/ to get the black screen and the 'puter locked up is to pretty-much disable (one step above none) all hardware acceleration for the videocard.
My question : Does anyone recognise it and knows how to fix it (other than
by keeping the hardware acceleration on a low setting) ?
Again the specs:
Computer : Optiplex 745
Videocard: Intel Q965/Q963 Express Chipset Family
Regards
Rudy Wieser
I would double check the memory allocation for the Q965
in the BIOS, versus the total system memory.
There are OpenGL drivers, which lack a working "mem avail"
call in OpenGL.
LibreOffice could not tell that OpenGL had run out of RAM, and something crashed as a result of the software failure.
I would sooner believe a memory issue, than some other
kind of issue. At least, as a starting point in the analysis.
