Googling for <intel modesetting tearing> brings up suggestions to run a compositing window manager, typically integrated with some complex desktop environment (GNOME, XFCE, KDE, ...). Personally, I just run mwm, the Motif window manager, without any further desktop environment. I have received suggestions in the past to run xcompmgr alongside it, but that only seems to supply eye candy, which more or less interferes with the window manager, while having no effect on an application like Firefox. I'm not very happy to add to the chorus of "I have no idea how any of this works, but pressing this magic button does it for me!", but it is what it is. -- Christian "naddy" Weisgerber naddy@mips.inka.de
