[Savage40] xe3 mode switch problems

Fri Jul 22 12:14:46 PDT 2005

Hello, 

Thank you very much - that was it! Your magic "XaaNoScreenToScreenCopy" fixed 
all the bugs observed earlier.

However I must say that I found the following options are the only working 
config for me:

Screen 0:
- "DisableTile" must be enabled if i want to watch movies without a little 
random garbage near the bottom of the screen

Screen 1:
- "DisableTile" must be disabled, or some strange bugs with cursor appear
- "SWCursor" must be enabled, or cursor will bring garbage on the Screen 1

And one more thing I should note: sometimes switching from a text console to 
the X, garbage appears at the top of the first screen, it can be fixed buy 
switching to any text console and then back to X.

Thanks again,
Dmitry
