Moonwalker's questions

I've recently decided to give ubuntu a try again. So far everything works fine except one strange detail.

I have ibus autostarted and sitting into my tray of i3 wm, but I didn't start it. my addions to the .i3/config are only following lines:

exec syndaemon -i 1 -K -d
exec nm-applet &
exec --no-startup-id nitrogen --restore
exec sleep 4 && xmodmap -e "keycode 107=Insert"
exec gnome-settings-daemon

More importantly pressing combination for switching layouts shows small windows which highlight switch to different layout, but nonetheless I still using default English one.

On linux-mint I've had the similar setup with only difference I did

exec cinnamon-settings-daemon

I'm trying to remap PrtSc key to Insert (to use it in vim), with /usr/bin/xmodmap -e "keycode XXX = Insert" for it, I need to figure out what keycode for PrtSc is.

I'm doing xev -event keyboard and pressing PrtSc, but getting something strange

KeymapNotify event, serial 28, synthetic NO, window 0x0,
    keys:  4294967228 0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   
           0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   

Not sure not extract the keycode from this information.

On ubuntu 13.04 Skype segfaults constantly (I've read a couple of threads about fixing the issue and it is kind of works now expect it segfaults every time chat message comes in) so I'm thinking it is time to find it a replacement.

Which one should I choose?

Ok, I've seen previous post, yet only one answer in it highlights some alternatives. Also I want no the alternative skype client, but the whole ecosystem.

The one alternative presented ooVoo does not support linux and other goober shows unresolved dependency: libglew1.5

I've been using VirtualBox for a really, really long time and enjoyed it but now I need to run Unity3D (dev tool, not the ubuntu shell) and this seemingly simple task turned out to be too much for humble graphical abilities of VirtualBox.

The thing is virtual box allows only up to 128mb of video memory (I've tried various tricks described over Internet to make it work with 256mb but with no luck) which is not enough for even IDE of Unity3D to start (it kind of starts but only kind of). Also with direct3d support enabled virtual box crashes when I try to do something in Unity and without it Unity3D IDE looks completely unusable.

I guess I need virtualization solution which capable of utilizing more video resources of my notebook hardware. I have 8 gbs of ram, radeon 5730 video card and also integrated intel card:

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12) (prog-if 00 [VGA controller])
    Subsystem: Micro-Star International Co., Ltd. Device 1037
    Flags: bus master, fast devsel, latency 0, IRQ 43

    Kernel modules: i915

I've tried to run unity3d in virtual box using both intel card and radeon with indistinguishable results.

Also, I've got error while installing vmware-player:

I've installed everything go-related from synaptic and later added ppa as described in the wiki: https://wiki.ubuntu.com/Go yet I cannot do "go get" for example

go get code.google.com/p/gorilla/mux

says that go command is not found.

How should I install this "go" command?

I want to change sudo timeout, so I edit sudoers via visudo (as adviced in many tutorials online) to the following form:

Defaults env_reset , timestamp_timeout=20
root    ALL=(ALL:ALL) ALL
%admin ALL=(ALL) ALL
%sudo   ALL=(ALL:ALL) ALL
Defaults:my_username timestamp_timeout=10

the problem is, that nothing works and it seems I have sudo timeout=0. This is my output from uname -a:

Linux comp 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

UPDATE

What I've noticed it's only happens when I use fish (aka user friendly shell). So problem probably with fish itself not with sudoers file.

SOLUTION The problem was with my shell fish aka user friendly (not very friendly this time, isn't it?) shell. For some reason it seemed that sudo command each time went from different sessions. Adding Defaults !tty_tickets in sudoers file (as described http://us.generation-nt.com/answer/bug-598567-sudo-requires-reauthentication-each-use-ignoring-time-stamp-help-200510161.html ) solved the problem. See the link above for the addition information.

Thank you all for your attention without it I could not figure the thing out.

If answer is negative then which workaround would be less painful? Reinstall the system? Run mongo in virtual machine with 64bit ubuntu?

For now I need mongo only for dev purposes, but my test database consists of 3kk entities so I'm afraid virtual machine will be inefficient.
