Gray background after wakeup after lion upgrade?

I have a MacPro i upgraded to Lion, it is a 2008 model with 2 Dell 27" monitors, and a ATI 5770 video card. After i upgraded to Lion everything seemed to work ok. the next morning i went back to the machine to wake use it again and when the monitors woke up, the background on the main monitor is grey, not the galaxy background that is the default. THe second monitor does not have this problem. Th only way i have been able to reset it to the image is to reboot, which i rarley do with this machine, It will stay on for months at a time, and i reboot only as needed. I have tried using the desktop & Screensave from system preferences and it does not do anything. I have even set it to change every 5 mins and it had no effect.

ANyone have a clue?

John

I've been able to resolve the background by just returning to login window and back to my session, without logging out.

Thanks @romacafe works perfectly!

Total RAM or memory in use? I've got 12GB of RAM in my iMac and I get this problem almost all the time.

I have 8GB of RAM in my MacBook Pro, and it does this all the time when I wake from sleep.

It depends what you mean by multiple monitors. I am using my MacBook Pro in clam shell mode, with only the external monitor in use.

the bottom line is that none would expect such a stupid bug from Apple.

For me, my experience with Mac OS X Lion has been as bad as Windows Vista.

Happens to me as well. MBP 15 early 2011. Logout/in works to reset it, as does going to the login screen (if you have fast user switching enabled).

I have a fix!

Open terminal and use this command: killall Dock

hit enter after and the screen will flash and then you can use wallpapers!

After upgrading to 10.7.3 working with additional monitor is a crap.

Same problem of gray background and new problems detecting monitors.
