Public bug reported:
Hi guys,
14.04 is working great, but I notice this strange thing. I have a Radeon 3100
in my PC. It has two connectors, DVI and VGA.
GUI is working seamless, glxgears showing 60FPS under all conditions (all
effects enabled, wobbly windows and dragging the glxgears window around ...).
When I connect the TV set to the VGA connector everything works as it should.
But after the first boot after shutting down the PC (and disconnecting the TV
set) the GUI is not seamless anymore. glxgears
shows FPS between 50 and 60, dropping down to 30 if dragging the window around.
After the second boot it is the same. The gui is stuttering.
After the third boot everything is fine. No stutter, glxgears shows 60FPS under
all conditions.
This is always the same. The system needs to be booted 3 times until it
is recovered from the connection at the VGA port.
I have added the logs, in which I can't see anything noticeable. But
maybe you guys do....
regards,
Hans-Peter
