Re: Xinerama Nvidia RT
Thanks, I'd nigh but given up on ever being able to use 2 monitors. I almost cannot wait to go to work and try this out now.

I can't test it because i'll only have one monitor !!! you can install by synaptic a software called grandr, a gtk gnome interface for xrandr which allow you to use 2 displays easily. to start grandr, open a terminal, and write grandr, a graphical interface will up, with your displays. I have a nvidia 7300 GS, with a vga port and a dvi port. so If it works, you can use 2 displays. I'm interested by the result on you computer... complete documentation here, but only in french... http://doc.ubuntu-fr.org/multi-ecran Laurent I was going to suggest xrandr (the console version) as this is what I use to control my Intel device. The console version seems to have more options and allow for greater control. It has the added advantage of working if you ssh in or use a regular console if/when you mess things up. No need to reboot or restart X. I am also curious to see how well it works with nvidia or ati using the open source drivers.

I have switched between the Ubuntu driver and the one from nVidia's website with no issues. Having said that, I have found that the binary drivers periodically behave oddly with RT kernels. Sometimes it works, sometimes it doesn't. Right now I am waiting for a new laptop that is Intel through and through (CPU, chipset, video, wifi etc.). I am done with binary blob and or non-supported hardware (that means you nVidia, AMD, broadcomm et al.) If you have the choice and RT is important, then stick with the open source drivers. If you absolutely *must* have some extra features, then buy hardware with proper drivers (right now that means Intel, though ATI is showing some positive signs and I may recommend them in the future). -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFI75qcwRXgH3rKGfMRAsBFAJ9BUDBeZQ3HITV/PuwufbLrDOtJKwCfaz8h Bnh761xn1dVkr08+yG9lAMo= =FvJD -END PGP SIGNATURE- -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
Re: Xinerama Nvidia RT
Ok will consider using intel when and if I upgrade. For now unfortunately I'm stuck with what I've got. Which kind of brings back the original question... Having the NV open drivers, and 2d graphics enabled, is it possible to have xinerama enabled via xorg.config or another way? or is it only possible with proprietary drivers? thanks for your input john -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
Re: Xinerama Nvidia RT
Yes, my desktop edition works fine with 3D graphics, NVIDIA drivers and Xinerama enabled. The problem is I've got a RME hammerfall and Behringer ADA8000 that NEED the RT kernel to operate without xruns. I think RT kernel is needed for low latency on any hardware. But I really wanted two screens! Maybe it is as Karoliina mentioned, AMD being the problem. If the RT kernel was mainstream, in other words, the RT would be in every desktop linux by default (without it being Ubuntu studio or some other distro for multimedia users), I would bet that the stability would become better as the userbase would be larger, there would be more people to file bugs at least. I think this should happen, it is a bit weird that there are two different branches of kernel on the first place, the RT helps even the responsiveness of desktop. For desktop use, the absence of RT has no purpose. In MacOSX real time kernel comes by default and it can not be disabled (of course someone might say now that, well, yes Mac does not even run on AMD hardware, but that is not the point here but how the kernel scheduling was designed). And as a consequence, there is no such thing as latency in audio applications, even with the internal hardware of MacBook one can do music with ease. Ordinary non-geek Mac-musicians propably don't even know what a latency problem is, they may have never seen such a thing, when you press a key in your master keyboard, a sound is produced by a software synth now rather than after 100 milliseconds, and that is without any tuning, without even knowing what xruns are, with default hardware without special drivers of any kind, it just works. This should be the case with Linux too. For Linux becoming more mainstream, I think it would be a good move to incorporate all the RT patches to ordinary desktop Linux kernels (e.g. ordinary Ubuntu) and stop having it as a separate branch.

With the Intel hw the machine seems to be stable with the RT kernel, so what I said above is not valid for the Intel configuration, I had the problems with the earlier hardware.
