The XFree86 driver for the sun Creator/Elite graphics cards, sunffb_drv.o, at about line 675 in ffb_driver.c has if (!FFBDbePreInit(pScreen)) return FALSE; However, FFBDbePreInit does not return a useful value (it returns the "return value" of a void function), so you can get random failures. Simplest workaround is to chnage this to just a call FFBDbePreInit(pScreen); since there is no useful return value here to test. Reproducible: Didn't try Steps to Reproduce: 1.Install "proper" graphics card 2.xinit 3. Actual Results: Depending on the graphics card or other unknown conditions, either X starts or you get Fatal server error: AddScreen/ScreenInit failed for driver 0 Expected Results: Start X. The bug is fixed, I believe, for anyone who runs in to it. I am posting this as an error report for reference and for tracking. I'll attach the patch which fixed it for Weeve,
Created attachment 8131 [details, diff] Fix improper test for failure in ScreenInit (sunffb) and trace Screen setup This seems to have fixed the problem Weeve was seeing, and it provides a little diagnostic information at the start of ScreenInit to help with other failures of this sort (if they are not the same failure.)
To respond to myself: Per note from Mike Harris (redhat/xfree86), this should be getting an official fix from xfree at some point. ------------------------------------------------------ I noticed in the CHANGELOG that your fix is committed to CVS now: 866. The sunffb driver was treating a function with a void return value as if it had a Bool return value. This causes the driver to fail in some cases (#A.1588, Ferris McCormick). -------------------------------------------------------
I am using a Ultra60 with a Creator3D card. After configuring X, the X Server did not start. The error message was the following: ========== Fatal server error: AddScreen/ScreenInit failed for driver 0 =========== After applying the patch, X came up fine. Stefan Brenner

sorry, my mistake ;(
This is fixed in xfree-4.3.0-r2 by changing FFBDbePreInit in ffb_dbe.c to read thus: ------------------------- extern void DbeRegisterFunction(ScreenPtr pScreen, Bool (*funct)(ScreenPtr, DbeScreenPrivPtr)); Bool FFBDbePreInit(ScreenPtr pScreen) { DbeRegisterFunction(pScreen, FFBDbeInit); return TRUE; } ---------------------------- I do not know if this is gentoo-only, or a general fix from the Xfree developers. I believe the latter, since they indicated that they had applied this fix. In any event, I think the proper resolution is Closed/fixed with release xfree-4.3.0-r2 (or whenever the fix first appeared).
as per Ferris McCormick's comment, i'm closing this bug
