I first got no dri with xorg-server 1.8, too, and then weird effects started happening, like the shift and ctrl keys not working. When tings crashed, I got a block screen and still could move the mouse, but that was all, even after Alt-SysRQ-R (which usually helps in these cases) I could not switch to a text terminal. But after a reboot all seemed perfect, but when I was writing a followe-up mail, X crashed. And I got several more crashes after working 5 minutes in KDE. I downgraded back to xorg-server 1.7.7-r1, and now dri is working, too. Looking good! KDE is running for over an hour now, I'm not using any swap at all, amarok is emerging in the background, and mplayer is playing smoothly. I experience little rendering problems in chromium (images appear over text) and quake3 feels a little sluggish, but I can live with this. Thanks for anyone who helped! Wonko
