If I use xscreensaver, or the screen saver starts from Gnome, or I run the OpenGL program stand-alone, everything works fine. But if I use KDE's screen saver program or it starts automatically in KDE, OpenGL screen savers get all flickery, as if double-buffering had been disabled. Apparently, this is a long out-standing bug in KDE. The only bit of this that is not off-topic is that ATI's proprietary drivers are broken, because they don't get along with radeonfb. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
