I installed your patch and I no longer get errors in the Xorg.0.log
file, but I still have problems.
I now have two displays, but the right display only runs at 1024x768
with the left runs at 1280x1024.
If I try swapping the "Position" lines between monitor 0 and 1, I go
back to the old mirror effect, with the right screen still at 1024x768.
I get the following messages on my vty:
WB: Reading 128K from /dev/mem address 0xc0000
info: [drm] Initialized card for AGP DMA
[config/hal] couldn't initialise context: (null) ((null))
The only warning in the log is:
(WW) OS did not count PCI devices, guessing wildly
(WW) MGA(0): Option "Position" is not used
I don't like the look of the latter error.
Any ideas? I did edit the "Monitor" sections and tried both with
explicit sync rates and commenting them out and using DCC. Made no
difference. I must admit that I am baffled.
Also, is xinerama no longer usable with the 7.3 and the G450? Or so you
just prefer randr? (I can see that randr has advantages.)
