LightDM aborts
LightDM aborts
Hi. Does anyone know why lightdm aborts when running 'Demo' in fullscreen? The screen freezes after a few seconds and before Sydney appears. I'm using nvidia-304 on ubuntu.

MAybe try to switch ton randr instead of the vidmode86 approach
Re: LightDM aborts
Are you saying *ahem* that I should modify some lightdm configuration file? I'm guessing that you aren't suggesting a change to xorg.conf.
Re: LightDM aborts
No - it's a define in IrrCompileConfig so far. It uses different methods. So you have to recompile Irrlicht for that. Would be interesting to know if that is the problem, but the crash could also have other reasons. For example nvidia-304 sounds rather old (they are around 331 now I think).

I'm running 12.04 LTS and the *stable* PPA is ubuntu-x-swat, which has 304. Anyway, the change to XRandR works. Thanks for your help.
By the way ...
Everything seems to work on Nouveau, if the desktop is 2D, otherwise the screen appears to freeze. I guess something has gone away. Also, it is a proper fullscreen, filling the entire screen.
I also tried 331 (downloaded from nvidia). I got a partial *fullscreen* with the desktop behind it and that Ubuntu update icon still wiggling (so the desktop may have been 3D). The desktop was now 4x3 and when I exitted Demo it stayed that way, maybe because Demo SIGSEGV'd (CDemo.cpp(254) in CDemo::switchToNextScene(). 'this' was 0 but I don't know why it stopped at Line 254.) I could now scroll the desktop!!
304 was similar - the fullscreen did not occupy the full screen (even with XRandR) and I got the SIGSEGV, though not with XRandR.
Makes me think the Ubuntu desktop is held together with string. Anyway, Nouveau has no trouble handling Irrlicht so I guess I will stick with that.
