Hi :) until now I switch between the FLOSS nv driver and the proprietary nvidia driver at startup, depending to the kernel I boot. IOW I use the nv driver with kernel-rt and the proprietary with 3.5.3-1-ARCH. If I try to boot the kernel-rt, I get a black screen. [spinymouse@archlinux ~]$ pacman -Qi nvidia | grep Ver Version : 304.43-1 [spinymouse@archlinux ~]$ pacman -Qi nvidia-rt | grep Ver Version : 304.43-1 [spinymouse@archlinux ~]$ pacman -Qi nvidia-utils | grep Ver Version : 304.43-1 [spinymouse@archlinux ~]$ pacman -Qi xf86-video-nv | grep Ver Version : 2.1.20-1 [spinymouse@archlinux ~]$ grep DAEMONS /etc/rc.conf # DAEMONS DAEMONS=(!69switch_xorg.conf hwclock syslog-ng !network !netfs crond acpid dbus networkmanager rtirq) Any ideas? The graphics is a GeForce 7200 GS. The nv driver is ok, but I have to readjust the monitor if I switch from nvidia and soon or later it will be dropped. The vesa driver won't provide the needed resolution and noveau
