I dont really know driver or chipset in detail, but its the way that it needs programming so that the timing for the LCD does match. black or striped or whatever effects do indcate wront timing for the flat pane display.
If the device is capable of dual head in other OS condtions then it can do it with Linux as well. Current AGP grafics chipsets in PCs do expose device 1:0:0 and 1:0:1 with different IDs (on AMD boards the 2nd number is higher). for real programming the first is preferable. in other words the driver must be capable of doing two outputs in parallel or it will only drive both outputs with identical timings and same contents. its a single graphics core and does need at least one output unit programmed. if neither of the driver does know about the other then there is a serious problem because they will heavily "fight" for the same output timing registers. -Alex. _______________________________________________ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
