Hi,<br><br>My OS is an up-to-date version of Fedora 7 on a Intel based PC.<br><br>I use a particular academic/scientific video rendering software VMD<br>( http://www.ks.uiuc.edu/Research/vmd/ ).<br>This software uses GLX/Mesa heavily.<br><br>My day-to-day window manager is XFCE. When I use VMD, it immediately<br>freezes keyboard/mouse on my console as soon as any video rendering<br>activity occurs. The typical error message in /var/log/messages is:<br><br> kernel: [drm:i915_wait_irq] *ERROR* i915_wait_irq: EBUSY --<br> rec: 147447 emitted: 147473<br><br>However, when I switch to KDE window manager, all this does not occur.<br><br>Obviously I first blamed XFCE, but the developers there are convinced<br>that the Xorg and/or related X11-video drivers are to be blamed.<br><br>Eventually I solved the problem: I disabled XFree86-DRI in the file<br>/etc/X11/xorg.conf.<br><br>Is
there anybody who knows about this matter and can help me<br>understand what's going on?<br>I'd like to report this problem somewhere, but who is to be blamed?<br> Xorg ?<br> Fedora ?<br> XFree86-DRI ?<br><br>Thanks,<br>Rob.<br><br><div> </div><hr size="1"><p>
