I need rebuild VirtualBox , for new Xserver 1.16 RC2 on rawhide , and fixed broken deps. Unfortunately , vboxvideo crash on startup X on a vm with Fedora rawhide as guest system.

Removing /usr/lib64/xorg/modules/drivers/vboxvideo_drv.so makes X startup but with vesa drive but loses all video capabilities

[Michael Thayer]

Investigating this now. I can reproduce the segmentation fault.

[sergiomb]

good news , I volunteer to test any untested patch .

Thanks,

Patch against the X server here:

​http://lists.x.org/archives/xorg-devel/2014-May/042497.html

Do make sure that you build vboxvideo against the header files in the X server you are using as there was an ABI change since 1.16rc2.

[sergiomb]

OK , ajax already did a build with this patch on rawhide ...
