    [SOLVED] xlock troubles

    Hi there Linux Forums!
    Whenever I run xlock I get this error message after a while:
    Code:
    xlock: main/renderbuffer.c:2078: _mesa_add_renderbuffer: Assertion `bufferName == BUFFER_DEPTH || bufferName == BUFFER_STENCIL || fb->Attachment[bufferName].Renderbuffer == ((void *)0)' failed.
Aborted
    I have an onboard VIA Technologies, inc. KN400/KM400/P4M800 video card, can any one tell me how to fix this?
    Thanks guys.

    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    Sounds like a bug in xlock. It is aborting after detecting a null pointer access. Since it has source file information, it must be built for debugging. Have you customized and/or built any of your X-Windows components (such as xlock)?

    Well xlock isn't part of the xorg package on my system. I can get xlockmore from the rpmforge repository via yum. What distribution/version of Linux and which X server are you running?

    Well, that pretty much confirms the bug diagnosis then. Someone built or installed (probably built since it is in a debuggable state) a version that has a bug in it. In any case, xlock is pretty much deprecated these days. If you want xlock, then you can use xlockmore, which is xlock, but more up-to-date. It's available in the rpmforge repositories. I haven't tried it yet, but their web site is pretty well done.
