Description Chris Spencer 2006-04-02 21:03:32 EDT
I have an ATI Radeon X300 PCIE video card configured for a dual-head display
with Samsung Syncmaster 914v monitors. Ever since I upgraded to FC5, dual head
is completely inoperable, and X crashes sporadically. With dual head enabled,
the mouse appears as a giant white square in the second screen, and moving
windows into the second screen cause my entire system to freeze or crash.

Attach the X server log file and config file from the problematic dualhead
configuration as individual uncompressed file attachments using the link

Thanks in advance.

 Note that the test update:


..."works" for me, in that the second monitor starts now (we'll see how stable
it is).

Comment 5 Chris Spencer 2006-06-25 16:48:49 EDT
Yes, I just installed it, and my second monitor seems to be working fine now.
I'll keep an eye out for bugs. Thanks!
Comment 6 Mike A. Harris 2006-06-27 11:21:57 EDT
If this problem is still present for you with FC6test1 or later, please
reopen and update the details.

Comment 7 Chris Spencer 2006-06-28 00:03:29 EDT
Just noticed a minor bug. If I try to drag a maximized window from one screen to
another, keeping the window's title bar at the top of the screen so that it
remains maximized, the window will repeatedly flicker between maximized and
unmaximized states and will refuse to transfer to the next screen.
Comment 8 Matěj Cepl 2006-11-23 03:32:43 EST
According to comment 6 this bug should be closed. Concerning comment 7 --
please, file a new bug for separate issue.
