Dear list, With 2.6.33.7.2-rt29 I could use my dual screen set-up fine with nouveau to span my desktop over the two screens but 2.6.33.7.2-rt30 only allows me to mirror screens. xrandr only recognizes one screen also. lspci | grep -i vga 01:00.0 VGA compatible controller: nVidia Corporation G86 [Quadro NVS 290] (rev a1) Monitors: 2x Dell ST2410 I use kernels from the Tango Studio project: http://tangostudio.tuxfamily.org/en And have talked about it with the maintainer of that repository/distro too and he actually found out about the regression and apparently he also found a fix (patched 2.6.33.7.2-rt30 kernel packages are being build and uploaded today so haven't tested those yet). I'm using Ubuntu 10.04 64bit.
