As mentioned, my xorg.conf is set as a big virtual > desktop shared between two screens..: exact details will depend very much on the graphics card and driver, but you should aim for the projector display to be the first, or primary, display, possibly use xorg.conf to turn on direct rendering for that one and off for the other. With NVIDIA most of this can be done with the driver GUI. Then either start pd from that display or give gemwin the appropriate message - I forget what it is but it was on this list a few weeks ago. simon ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

[PD] [Gnome/Ubuntu] Gem video on external screen
Hi all, Im a bit desperate to find a way to play video on an external screen without Gem (or even X/Gnome) crashing. Ive set up xorg.conf to a virtual screensize of the double horizontally so as to have a projector read the video from the "right part" of the screen, and still have my GUIs visible on the "left part" (what is visible on my laptop screen). This is how it looks in xorg.conf: Section "Screen" Identifier "Default Screen" Device "Intel Corporation Mobile GM965/GL960 Integrated Graphi$ Monitor "Generic Monitor" DefaultDepth24 SubSection "Display" Depth 24 Virtual 2048 768 EndSubSection EndSection The CPU jumps to 60% when playing video with the external screen on, but lays nicely on 8-9% when only playing on the normal screen. I guess lots of people are working with similar stuff - are there other (more stable/safe/efficient) ways of getting to this? or is the high CPU something to expect when using an external screen? Are there any good ways of finding the source of Gem crashes btw? Im very happy for any feedback as Im quite fresh on both Gem and projections :) cheers, Martin ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
