Hi, directfb-users would be the right place, but let's continue this thread here to avoid confusion ;) > I just checked out XDirectFB and DirectFB from CVS this morning, rebuilt > both, and fired up XDirectFB.

I just committed a fix to the keyboard driver that makes XDirectFB work again from linux console (I know it should have been an issue in vt.c, this will be cleaned up soon). I don't know exactly why this happened with XDirectFB only. I could not really debug it, because it works when started in strace ;-P But it didn't in gdb, so it's not a ptrace issue, I think. > The video card is a Matrox G400 32mb, dual-head capable. 32M is nice for many, many windows ;) > The machine is alive at the kernel level (I can ssh in, etc), but all of > the virtual consoles, keyboard, and mouse are locked up, even when > XDirectFB terminates on SIGTERM. Did you try Ctrl-Alt-BackSpace?

You would have been surprised like me ;) Please try again and don't worry about the error messages, these will disappear after I understood all this VT/TTY voodoo ;) -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" convergence integrated media GmbH -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-dev" as subject.
