Dualscreen, AIGLX, FC6, Problem, HELP :confused:

[leon85]

Ive just installed Fedora Core 6 (final release) and i got my latest nvidia beta drivers installed from this guide
http://clunixchit.blogspot.com/2006/...ta-driver.html
im running KDE with dualscreens, primary monitor is 20.1" 1680x1050 and the secondary monitor is 17" 1280x1024, i got everything installed and working fine EXCEPT when i get to step to type in konsole desktop-effects, the desktop effect open for me but when i click on enable desktop effects i get this error

[root@localhost ~]# desktop-effects
compiz: No RandR extension
The program 'gnome-window-decorator' received an X Window System error.
This probably reflects a bug in the program.
The error was 'RenderBadPicture (invalid Picture parameter)'.
  (Details: serial 618 error_code 180 request_code 155 minor_code 8)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

any help would be appreciated

same thing here... im guessing there is no support for xinerama

works with single screen but not when i enable the other screens

i got it working with twinview but the only problem is that when you maximize a window, it maximises into both screens and not only in one screen !! (which is annoying sometimes) also if you launch a program that has a splash, the splash will show half on one screen and half on the other one!!, does anyone has a fix for that?

that is normal for twinview, twinview will make both screens act as one, instead of acting as seperate screens as one desktop

ok, i see, then so far there is no way to enable that with xinerama? i kinda like xinerama more than twinview!

How did you get it working? I'm using twinview on two identical monitors and I'm still getting the RandR problem.
My X log is showing that RandR loaded without problems.

when you use twinview, you need to disable xinerama, i have two monitors one 20.1" and one is 17", here is my xorg.conf

P.S. beryl has a fix for dual monitor, when you maximize, it maximizes on only one screen
