I'd like to get away from xinerama as it doesn't seem to allow for 3D... </pre> </blockquote> <pre wrap="">It depends on what you need to do, but if you don't worry about Xinerama and just set the monitors up as separate X11 screens then you can have 3D acceleration across them all. </pre> </blockquote> <tt>Yeah, I want my cake and eat it too. :) One bigdesktop, 2 GPUs, 3 screens. At least that's the goal... </tt> <blockquote cite="mid:h8ijuv$vh0$1@ger.gmane.org" type="cite"> <pre wrap="">The only downside with this is that you can't drag windows between screens (which is what Xinerama was created to solve.) The nVidia driver can combine multiple monitors into a single X11 screen though, so you could use that to get 3D acceleration across screens, but I suspect this is on a per-GPU basis. Still, with two GPUs you could have two 3D accelerated X11 screens, with one screen being split across two monitors... </pre> </blockquote> <tt>Twinview. works great, but not across multiple GPUs. In this particular case, I need to rotate one of the monitors, which I haven't figured how to rotate the left monitor and then twinview it to the center. It's a strange use case... I admit. It's also for a friend, so this is really all charity work too. :) </tt> <blockquote cite="mid:h8ijuv$vh0$1@ger.gmane.org" type="cite"> <blockquote type="cite"> <pre wrap="">Is it possible to use xrandr in this configuration? If it is, can some one point me in that direction? I've been all over google, and really... am just more confused. </pre> </blockquote> <pre wrap="">I'm probably wrong, but I always thought xrandr was for adjusting screen resolution and settings, I didn't think it had anything to do with combining multiple screens into a single display. Perhaps it has advanced since I first used it... Cheers, Adam. </pre> </blockquote> <tt>Thanks for the reply. I've been going off this snippet, that I came across in a couple different forums: "As of 2008, Xinerama is planned to be deprecate in the future by X.org in favor of Xrandr.<a href="http://en.wikipedia.org/wiki/Xinerama#cite_note-0"></a> X.Org had convened a standards committee to document the protocol and API as formal standards, but that effort has now ended. </tt><tt>Development of the Xinerama code is now hosted on freedesktop.org and managed by X.Org." That seems to imply that Xinerama functionality will be replaced by Xrandr - unless I'm reading that wrong. I couldn't find specifically how to do that with Xrandr though. I've got a couple more things I'm going to try... hopefully that will work. In the end I think it'll be about settling with Xinerama or living with separate Xscreens. thanks again...
