Description Brian 2008-02-27 22:48:44 UTC 
When I enable my external LCD monitor using xrandr I seem to lose EXA acceleration, I base this on the fact 2d acceleration seems to have gone away, there is not log output confirming it. Things get drawn/refreshed incorrectly across the two screens as windows move, and take a few moments to get refreshed properly. When returning to just outputting on the LVDS EXA works again.   

XAA seems to work in both dual and single monitor configurations. 

I am using commit e40d75fd8b2aece9dae8076fac822a4a83025fb2 from git. 

The card is an R500 chip in a e1505 laptop. (x1400 mobility) 

I attached the Xorg log. My configuration file is pretty standard. No monitor section in the file, I setup a virtual screen size of 2960x1050. 

Thanks.

Yes, I applied the patch and now when I enable the second monitor EXA continues to work. 

Thanks for the quick turnaround on the problem.

Heh, it's because this was already discussed on the mailing lists a couple of days ago, the reporter there just hadn't got around to testing the fix. Thanks for giving it a spin.
