hello

I'm getting the following message with Blender 2.5 alpha 2
"do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
Try adjusting the vblank_mode configuration parameter."

after this message it often stops responding.

I'm running Blender 2.5 alpha 2 on a Dell vostro 1700 (with Intel graphics card) and Linux (karmic koala) from a terminal.

how or where can I adjust the vblank_mode parameter?

thx
