Black screen with Trident 3DImage975 and XFree86

Applies to

SuSE Linux: Version 6.0
XFree86: Versions since 3.3.3

Symptom:

You have a Trident 3DImage975 graphics adapter installed in your system but if you the start `SaX' your screen wents black and the system stops working. If you use xf86config or XF86Setup you are able to configure the X-Server, but if you try to start the configured X-Server the screen simply wents black and the system hangs.

Cause:

An usual cause for this is that the graphics adapter has to share its interrupt with another adapter. The X-Server cannot handle this and the system crashes.

Solution:

Please adjust your BIOS setup in a way that an exclusive interrupt is assigned to the Trident 3DImage975. Sometimes it is necessary to change the PCI cards in the slots to achive this goal. If you own the AGP version of this graphics board, it is perhaps necessary to remove the PCI card located in the PCI slot benath the AGP slot. In most cases the PCI slot located beneath the AGP slot shares the interrupt with the AGP slot. if you cannot get an free exclusive interrupt for your graphics adapter it is possible to add the `no_accel' option in the section "Device" to the file /etc/XF86Config.

Section "Device"
    Identifier  "Trident 3DImage975 AGP (generic)"
    VendorName  "Unknown"
    BoardName   "Unknown"
    Option "no_accel" 
    #VideoRam    134548056
    # Insert Clocks lines here if appropriate
EndSection

You can configure this option also with sax using the dialog Card->Expert->Options. You should get a display after this change, but the X-Server doesn't use the acceleratione engine of the Trident 3DImage975.

Extension

This Bug should be solved in a newer version of XFree86. A rpm configured for SuSE Linux can be found at the URL ftp://ftp.suse.com/pub/suse_update/XFree86-3.3.3.1-SuSE/. Additional options can be found in the file file:/usr/lib/X11/doc/README.trident.
