15 I first got no dri with xorg-server 1.8, too, and then weird effects
16 started happening, like the shift and ctrl keys not working. When tings
17 crashed, I got a block screen and still could move the mouse, but that was
18 all, even after Alt-SysRQ-R (which usually helps in these cases) I could
19 not switch to a text terminal. But after a reboot all seemed perfect, but
20 when I was writing a followe-up mail, X crashed. And I got several more
21 crashes after working 5 minutes in KDE.
22
23 I downgraded back to xorg-server 1.7.7-r1, and now dri is working, too.
24 Looking good! KDE is running for over an hour now, I'm not using any swap
25 at all, amarok is emerging in the background, and mplayer is playing
26 smoothly.
27
28 I experience little rendering problems in chromium (images appear over
29 text) and quake3 feels a little sluggish, but I can live with this.

31 Thanks for anyone who helped!
