Moritz, I don't know if you ever got this resolved or not, nor do I know if you have been following the follow-on discussions or not (helpful to me, not so directly to the CG6 case.) In any case, here is an idea which I have no way of testing, but which parallels David Miller's suggestion regarding the Creator graphics card. The kernel code seems to blank/unblank a display device connected to a CG6 frame buffer seems to use the mask CG6_THC_MISC_VIDEO in the module [cgsixfb.c at cg6_blank] thus: tmp = sbus_readl(&fb->s.cg6.thc->thc_misc); tmp &= ~CG6_THC_MISC_VIDEO; wbus_writel(tmp, &fb->s.cg6.thc->thc_misc); This suggests that changing the XF86 cg6 driver module --- cg6_driver.c --- as follows should get you screen blanking at least: The current CG6SaveScreen procedure is an empty procedure returning TRUE. Something along the following lines might do what you want-- static Bool CG6SaveScreen(ScreenPtr pScreen, int mode) { ScrnInfoPtr pScrn = xf86Screens[pScreen->myNum]; /* Like elsewhere*/ Cg6Ptr pCg6; unsigned int tmp; pCg6 = GET_CG6_FROM_SCRN(pScrn); tmp = pCg6 -> thc -> thc_misc; switch(mode) { case SCREEN_SAVER_ON: case SCREEN_SAVER_CYCLE: tmp &= ~CG6_THC_MISC_VIDEO; break; case SCREEN_SAVER_OFF: case SCREEN_SAVER_FORCER: tmp |= CG6_THC_MISC_VIDEO; break; default: return FALSE; } pCg6 -> thc -> thc_misc = tmp; return TRUE; } If you try that and it works, there are some other THC_MISC masks which might get the display device to turn off. As I mentioned a couple weeks ago, something along these lines will turn it off: Solaris knows how to do it. Sorry to be so long-winded. Hope this is of some use to you (or that someone who actually knows will correct it into something useful).
