It now works fine, but I'm willing to help out in tracking this bug down completely. Meanwhile we were able to pin this down to the SetGamma() function. But even with SetGamma() commented out it has been reported that attempting to play a video would crash the chip hard. We have no idea yet, why this happens. If you want you may help us to track this down. Please take a look at the chipsets video setup which happens in TRIDENTDisplayVideo(). By commenting out some of the code there you may be able to pin this down some more. The video won't display properly any more but first we need to know why it crashes before we can fix it.

Egbert Eich ___ Egbert Eich Xpert mailing list Egbert Eich [EMAIL PROTECTED] Egbert Eich http://XFree86.Org/mailman/listinfo/xpert Egbert, here are the results from today: First I removed the comments from the trident_driver.c file that commented out the XvExtension function. I then edited the trident_video.c file, within the TRIDENTDisplayVideo() function I commented out the Horizontal Zoom section. I did a make clean, make, and saved the resulting trident_drv.o module. I then edited the file again, this time commenting out the Vertical Zoom section. Rebuilt and saved the module again. I then did four tests using Xmovie and an mpeg clip at 1024x768 resolution in 16 bit color. First test used the original stock trident_drv.o module-the mpeg clip played just fine although in distorted color along with the rest of the display. The second test used the patched trident_drv.o module that had the XvExtension function removed. I got good 16 bit color, the mpeg clip played but with a distorted (slanted) output. The Xserver did not lock or crash. Third test used the trident_drv.o module that had the Horizontal Zoom function removed-I got the same results as the second test. The Xserver ran fine in 16 bit color with a messed up mpeg clip under Xmovie, and did not lock or crash. The fourth test used the (you guessed it) trident_drv.o module that had the Vertical Zoom function removed and got the same results as the second and third tests. Between each module swap and test I did a complete powerdown of the laptop, so the display was initialized from scratch. Let me know what to do next. -- Best regards, Mikemailto:[EMAIL PROTECTED] ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
