xorg does not work (ATI r128m with dual monitors)

My laptop uses the ATI Rage128M display card with dual monitors which are set to work independently. The file xorg.conf is as follows:

Originally I use the package xf86-video-ati as the driver which worked fine. But after upgrading to the latest xorg package in last weekend, the "r128" driver cannot be loaded.
According to the article http://bbs.archlinux.org/viewtopic.php?id=59981, I installed the package xf86-video-r128. Now the system can load the driver, but does not accept the configuration in xorg.conf. Here is the log (I ignored unimportant information):

BTW, if I change the driver from r128 to vesa in xorg.conf, xorg server can be launched, but two monitors display the same thing.

Re: xorg does not work (ATI r128m with dual monitors)

do:

pacman -Sy xf86-video-r128

that should get your driver back, at least.

Edit, explanation: apparently xf86-video-ati only supports radeon cards now and the old r128 card get their own driver package, I had the same problem

... imagine I'm making this argument without referencing cartoons.

Re: xorg does not work (ATI r128m with dual monitors)

Yes, I have tried that. Now the problem is that two monitors cannot share the display card using the xf86-video-r128 package.

Re: xorg does not work (ATI r128m with dual monitors)

I have conducted some experiments today, which shows the problem comes from the "Screen" statement (I need to use one display card to control two screens):

Section "Device"
    Identifier  "ATI_R128M"
    Driver      "r128"
    Screen    0
    # BusID    "PCI:1:0:0"
EndSection

Section "Device"
    Identifier    "ATI_DUP"
    Driver    "r128"
    Screen    1   
    # BusID    "PCI:1:0:0"
EndSection

If I remove these two lines, the xorg can be launched, but only the main screen is used.

Does anyone have any idea or suggestion about configurating dual-head monitors using Xinerama? Thanks a lot!

Re: xorg does not work (ATI r128m with dual monitors)

My only suggestion is to use either xinerama or the xRand utility to enable dual-head.  Aside from that, ati usually will allow one to do either of these:

 Dual head   :    aticonfig --initial=dual-head --screen-layout=above
                        This command will generate a dual head configuration
                        file with the second screen located above the first
                        screen.
  2. Setting up big desktop to horizontal and set overlay on secondary display.
                        aticonfig --dtop=horizontal --overlay-on=1

Do neither of the above commands work for you at all?

Re: xorg does not work (ATI r128m with dual monitors)

Thanks for your reply. But unfortunately my video card is ATI Rage128m, which seems not supported by the tool aticonfig. I cannot find the command in the system.
