Oddly enough, the problem vanished when I started the computer with the second monitor plugged in but turned off this morning and rearranged the dual-screen config with the screen applet. X still but started with mirrored screens at 800x600.
I will check the following: - secondary screen added after X starts - secondary screen plugged in but turned off when X starts - secondary screen plugged in and turned on when X starts I hope this sheds some light. Anyway, kudos for the folks who solved part of the problem whatever it was. -- [i945] Cursor movement, screenshot clipping and redraw problems on dual-headed, Intel 945GME desktop after 20081125 compiz/X update https://bugs.launchpad.net/bugs/302227 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
