I installed Slackware 10 the day after it came out, added
powervr-2.01.21-7.tgz drivers and I had glxgears at 1100fps on my duron
900 and decent mplayer video playback using -vo gl2.

I use slapt-get to keep my system up to date and a few days ago I
noticed my OpenGL screen savers on KDE had stopped working.

In /etc/X11/xorg.conf I still have

Section "DRI"
Mode 0666
EndSection

and

ls -lR /dev/dri
/dev/dri:
total 0
crw-rw-rw- 1 root root 226, 0 2004-07-18 12:30 card0

and as far as I can see /usr/lib and /usr/X11R6 stuff has world read access.

When I boot with "init 3" and login as a user, startx fails after
(II) loading /usr/X11R6/lib/modules/drivers/libPVR2D.so
whereas startx as root goes on to tell me vendor info etc
(II) module libPVR2D ...

Any ideas what I've screwed up, or what update I've installed that is
incompatible with powervr kyro drivers?

Sussed.

Found other non-root user could run openGL so had a delve in my home
folder and deleted ".powervr_kyro.ini" which had references to a few
dodgy KDE apps that had not worked and I'd uninstalled.
