Description Dan Hollis 2005-05-30 11:42:37 UTC

FC4T3 i386 correctly probes monitor. FC4T3 x86_64 on exact same machine fails.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Run i386 installer. Probing for monitor type: PHILIPS 107S
2.Run x86_64 installer. Probing for monitor type: Unknown
3.Profit!
  
Actual results:
x86_64 installer is unable to probe monitor. while i386 installer on exact same
machine works fine.

Comment 1 Jeremy Katz 2005-05-31 03:11:13 UTC 
This is because the real mode monitor probing we do can only be done on i386 and
not x86_64.  Unfortunately, there's no generic, cross-platform way to do monitor
probing and the methods that do exist are all card-specific.  X has code for
doing this, but doesn't really export it in a way that can be used.  There's
another (old) bug for tracking fixing that at which point we can do something
better.

what's the bug number for tracking it? might be nice to make 159128 'depends on' it.
