Gerry, You could also use DirectFB's X11 system module, so that you can run DirectFB-based applications in a usual X11 window. You can tell DirectFB so by using the DFBARGS environment variable: $ export DFBARGS="system=x11,mode=1280x800" (probably also w/ disable-module=gl) $./<your_directfb_application> Nicolas Chauvet is now upstreaming changes for Fedora to directfb-dev ML. -Ilyes On Wed, Aug 29, 2012 at 8:29 PM, Gerry Reno <greno@xxxxxxxxxxx> wrote: > On 08/29/2012 02:33 PM, Tom Callaway wrote: >> On 08/29/2012 09:25 AM, Gerry Reno wrote: >> >>> DirectFB says that there are Fedora packaging errors which are causing the undefined symbol on XUnlockDisplay and >>> inability to run as normal user. >> Upstream is wrong, btw. >> >> The dlopen problem is caused by the fact that they don't pass the >> $(X11VDPAU_LIBS) to the LDFLAGS for linking libdirectfb_vdpau.la. >> >> The core issue behind why dfbinfo doesn't run as a "normal" user is due >> to the fact that the Linux kernel requires CAP_SYS_TTY_CONFIG to do any >> TTY ioctl() calls.
