seems this thread is related, it's kinda old (February 27th, 2009) but the problem is same, enable Xinerama and watch it crash
http://ubuntuforums.org/showthread.php?t=1003263 no look with vesa drivers for me maybe there is no simple solution to this problem and it seems that it is not a nvidia-driver specific problem, rather a general Xinerama problem. I really want to use Xineram again (atm I have 2 nvidia cards, one amd, and 5 available screens so it would be awesome to use them all) maybe it works with wrapping it with Xdmx... What should I try next? testing with vesa? trying nv or nouveau? maybe X trys to start xrandr which fails on multi-gpu systems. file a bug against Xinerama or Xorg? posting some not interesting Xorg.log files? -- Xorg hard crash on nvidia multi-gpu system https://bugs.launchpad.net/bugs/363011 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers-180 in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
