I think it has something to do with a bug in the dapper version of xserver-xorg-driver-nv . I guess I had also that problem on gentoo but got solved after an upgrade. So did I in Ubuntu, decided to upgrade to edgy and the problem got solved, now I can use either X11 and X11/Xv.
Another issue is that I can not use xrandr to change the orientation of the screen (neither in Dapper nor in Edgy) but works well when I fix it on the Xorg.conf file (after a restart). Thanks for the support Jose Fernandez. -- No X11/Xv support (X11 error: BadAlloc (insufficient resources for operation) ??,?% 5 0) https://launchpad.net/bugs/62465 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
