dualview (not bigscreen) problem

[wanis]

Hi,

i just cunfigured my xorg.conf, and i have a problem with dualview on my ATI radeon EAX1600 PRO with 512Mb (Radeon X1600 Series). ATI driver works good, OpenGL is supported, DRI enabled.
performance:

[root@localhost ~]# glxgears 
17967 frames in 5.0 seconds = 3593.368 FPS
17980 frames in 5.0 seconds = 3595.969 FPS
17968 frames in 5.0 seconds = 3593.536 FPS
18276 frames in 5.0 seconds = 3655.157 FPS
18492 frames in 5.0 seconds = 3698.297 FPS
[root@localhost ~]# fgl_glxgears 
Using GLX_SGIX_pbuffer
3045 frames in 5.0 seconds = 609.000 FPS
3900 frames in 5.0 seconds = 780.000 FPS
3909 frames in 5.0 seconds = 781.800 FPS
3903 frames in 5.0 seconds = 780.600 FPS
3879 frames in 5.0 seconds = 775.800 FPS

On root user the screen is like it should be - dualview, but in antother users it simply creates clone on second monitor.

has anyone sloved this kind of problem ?

I have noticed that ATI contorl panel in root showing "Big Desktop Horizontal", and in antother user it shows "Clone Mode". But if i change it to "Big Desktop Horizontal", it says, that i have to restart Xserver, and after restart, (tryed ctrl+alt+backspace and even reboot) settings didn't changed

[jacksmash]

did you try switching 'single head...' to 'Multihead' ?

No, it didn't helped.
But i sloved this problem by adding new user, logged in to it, and replaced created new files to old user.
Now i have what i want Thanks to this forum to make my ATI working !
