i'm running nvidia drivers 367.57 on precision 5510 (quadro m1000m + skylake). it's connected external monitor via displayport through dell d3100 dock. i'm running ubuntu 16.10 kernel 4.8.1. i've got bumblebee installed, , it's working correctly when using intel graphics. when switch nvidia graphics (and of course, bumblebee can't work), external monitor shows output, laptop screen blank. xrandr sees second screen - doesn't list laptop one. the other issue i'm seeing when using intel graphics, bumblebee works, performance worse. e.g. glxspheres running on second monitor without optirun 1/s, optirun 200/s, when switched nvidia graphics, it's 2000/s. furthermore, bumblebee, dragging on second monitor slow, typing in terminal. these issues non-existent when using nvidia graphics only. are these issues common? there known workarounds? update: also, bumblebee, when running glxspheres on internal screen, intel gives around 55-60/s, while optiru...

i've got 2 ubuntu-servers, each of them 2 ethernet cards. i'm trying switch 1 other high availability purposes. unfortunately, when querying arp mac address of first card (eth0) , not 1 of second card (eth1) ip-address has been dynamically assigned. can do? example: server 1: eth0 mac: 00:11:11:11:11:11 ip: 192.168.0.1 eth1 mac: 02:33:33:33:33:33 ip: 192.168.0.3 server 2: eth0 mac: 00:22:22:22:22:22 ip: 192.168.0.2 eth1 down (goes mac , ip server1 eth1 when server1 goes down) when execute arp -a 192.168.0.3 command windows machine, result 00:11:11:11:11:11 (eth0) , not 02:33:33:33:33:33 (eth1) what you're trying not impossible, not optimal neither... back in xxth century, used exactly you're trying now, in xxist century, use bonding gives both reliability , higher throughput when both cards up. so forget 2 ip addresses on 2 nics, go 1 ip address on both nics , take advantage of double throughput! :-)

this question has answer here: how make directory? [closed] 2 answers i not know how create directory within home directory. need name directory a452. how do this? i'm sure teacher impressed mastering terminal environment invoke hot-keys ctrl + alt + t . new text based window appears. default, terminal opens in home.directory can enter mkdir a452 to create directory - mkdir command m a k e dir ectory, , if no explicit path specified, command executed in current working directory. however, if current working directory not home directory, you'll need manually force use of it, can known tilde ( ~ ), automatically refers user home. mkdir ~/a452 that create directory under home directory. bonus let teacher know how close terminal window typing: exit make sure put "ask ubuntu" bibliography.
