Summary: radeon: incorrect crtc for external LCD on VGA-0
Product: xorg
Version: git
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/Radeon
AssignedTo: [email protected]

Video card on x86 laptop:
ATI Technologies Inc Radeon R250 [Mobility FireGL 9000] (rev 02)
I used to have an old external CRT monitor attached to the VGA-0
connector and the command `xrand --output LVDS --off` would
correctly turn off the laptop's LCD so I can work in the external
without having both monitors powered-on.
Problem now is that I buy a new external LCD monitor and the
above command would turn off both the new LCD and the laptop's
LCD.
But when `xrandr --output VGA-0 --crtc 0` everything works as
expected so I pressume is a bug in the crtc detection when a
LCD is attached in the VGA-0 connector both monitors are driven
by the same crtc. As I said, plugging the CRT monitor doesn't
exhibit this problem.
Running latest Debian Sid (X Server 1.4.0) and git radeon driver.
