Hi Vince and Roland, Thank you for the reply, but unfortunately, they did not work.
I closed the laptop, connected the monitor and restarted the laptop, "xrandr -q" only gave the information of integrated monitor, no external monitors' information and "xrandr --auto" did not give any information. I also tries "sysctl -a |grep enable", the output is: kern.smp.forward_roundrobin_enabled: 1 kern.smp.forward_signal_enabled: 1 vm.swap_enabled: 1 vm.swap_idle_enabled: 0 vm.idlezero_enable: 0 vfs.nfs.nfs_directio_enable: 0 vfs.vmiodirenable: 1 net.inet.tcp.sack.enable: 1 net.inet.tcp.inflight.enable: 1 net.inet.sctp.ecn_enable: 1 hw.firewire.phydma_enable: 1 hw.pci.enable_msix: 1 hw.pci.enable_msi: 1 hw.pci.enable_io_modes: 1 hw.apic.enable_extint: 0 machdep.enable_panic_key: 0 security.bsd.suser_enabled: 1 There seems no entry about monitor -- If I miss something please advice me. PS. The laptop is a Compaq Presario V3431AU. -- Best wishes, Kemian _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
