[Gllug] DRI and multihead

[Ian Norton]

thanks tet :-)

i managed to answer my own question about 20 mins after posting, what i have
used as a solution is to run it normally with xinerama for gnome etc, and run
another x server on one of the heads as display :1, ive set it to run twm and
its handy for playing games like chromium and quake3 :-),

dri with both cards in non xinerama worked but i found it to give intermittant
(2sec) jolts in rendering when using a dri app, (i think its because the
voodoo3 is only happy with a irq and only one of my cards can have one,
(windows use is wierd unless i disable one card, note: i got it working in
debian before i tried windows :-) ) 

i set myself a XF86Config-4 for xinerama and another in my home dir for a
single head, i can do startx normally for the xinerama display and do :-

X -- -xf86config XF86Config-4-singlehead :1

to run another x server as display 1, and then run twm in the usual twm
-display manner :-)

lets just hope they dont overheat :-)
