Sorry for a late reply. I don't subscribe to the -user mailing list so I am just seeing this now:

I agree testing is a head ache. Battery life: This makes me feel somewhat better. I was wondering why my battery life went from 3.5 hours to 1.5 so fast. I think I will install the generic kernel and boot to it when I don't need low latency to see if that makes a difference. I have never run windows on my netbook so it should be a generic to lowlatency comparison. It could be a ver 2.6 to 3.2 issue, but I would think there would be more hoopla if that was the case as that would affect all of ubuntu. If I look at my use cases, When I need lowlatency, I have power. The package name is linux for the generic kernel. It should be possible to choose which one to boot from the boot screen. For straight two track recording a long latency should work fine. Dual Monitors: This one is harder and more painful. It takes two programs to make this work and even then there are a lot of places for it to fail. Arandr (gui) or Xrandr(CLI) are used to get the setup you want with two displays. With arandr there is a save option which I would use to save a backup. With xrandr I would find what works and create a script as a backup. Once the settings are in place, go to settings->settings manager and select Display. It will show the two displays but not the positions. Then to make it save your setup I change rotation to inverted and back... it doesn't matter what, just some change so that it will save it's settings. Now if you reboot the setting should be correct at login. Where this will fail.... the bad part. If when you boot, one of your monitors is not plugged in or not powered on, then X and/or xfce (I'm not sure which) will reconfigure to single diplay and your settings will be lost. This would be the time to use your back up (see above) to reset things. An alternate method, if you feel comfortable with writing a script, is to write a script to run at session start that has a small delay and then checks to see if there are two displays and if so runs an xrandr command to set two displays. I don't know if X sends a signal or sets some other testable parameter that could be monitored and used to change things on the fly. Another gotcha is that unplugging one display in the middle of a session will leave the remaining display in the middle of the area used by the two displays so you won't be able to see the main menu to reset things or logout or do much of any thing. The settings need to be changed to single with settings first and then remove the second display. One final note: I don't use dual monitors, I had to borrow one to test all this stuff with. That means there are probably things I have missed that using such a setup on a day to day basis would show. Also, I did not use any proprietary drivers, so if you are using an nvidia card with the nvidia driver and not nouveau. I don't know how that works, but I do know it is different :P Google ubuntu nvidia dual monitor or some such. If you are using nouveau, This should work... I tested this not with a video montor, but by simulating one by shorting the video out (it looks for 75ohm load) . arandr showed that I could move the displays around just like with two vga displays, but I did not actually see the video. -- Len Ovens www.OvenWerks.net -- Ubuntu-Studio-devel mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
