--- Comment #5 from Alex Deucher <[email protected]> 2011-05-24 10:35:37 PDT --- The problem in this case is vram fragmentation. When you start X, the driver allocates a buffer large enough for both dualhead (1024x768 + 1600x1200). When you turn off the LVDS port, the driver tried to allocate a new 1600x1200 buffer for just the VGA monitor before freeing the previous dualhead allocation. since there isn't enough VRAM available for both the dualhead allocation and the VGA only allocation, the modeset fails. Does it work if you start X without tha VGA monitor connected? Then connect it after you've started X, something like: xrandr --output VGA-0 --off xrandr --output VGA-0 --auto --pos 0x0 xrandr --output LVDS --off -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
