Hi All, I have done extensive testing with UBStudio 8.04 on a Dell XPS1530 laptop (nvidia) with a monitor plugged into the VGA port.
The test was done with: - FFADO - qjackctl - Ardour - 2 Audiofire12's - Ardour recording 24 channels Different test configs: 1. laptop screen only 2. external screen only 3. desktop spread across both laptop and external monitor Results: - config #1 can record for long periods (1 hour +) with no xruns. - config #2, & #3 rarely go more than 30 minutes without xruns. #2 & #3 improve if the jack priority is max'ed to 89, but the display update response suffers drastically. This is using the free nvidia drivers. I suspect this is an nvidia driver or X issue. Any thoughts to address this are welcome.
