Is this reproducable on other platforms?
Comment 2 yilong, sun 2012-01-18 17:02:27 UTC 
The command "clear" run well on other platforms.
Comment 3 Tom Zanussi 2012-04-19 14:02:27 UTC 
With current master of both poky and meta-intel, I'm not seeing this problem - 'clear' clears the screen fine.

Comment 6 Tom Zanussi 2012-04-25 04:01:02 UTC 
Apparently the problem is that mesa-demos builds and installs a demo program called 'clear' into /usr/bin on emenlow, which is what gets run instead of the system 'clear'.  mesa-demos is included only when enabling tools-testapps.  The reason it worked for me is that the build I tested didn't enable tools-testapps.

The solution is to test with a build that doesn't include tools-testapps.  The real fix probably would be to modify mesa-demos to not install into /usr/bin but rather into a separate demo apps directory.
