David Kamer's questions

I really like Ubuntu Studio and I enjoy the look, feel, and functionality along with the expanded capabilities of the the low latency kernel.

However I'm mostly a coder, and I like to have a lot of things open at once, and sometimes this can be really bad with a low latency kernel, so I decided to install the generic kernel to boot into when I'm not doing something like design or game development. I installed it like this:

sudo apt install linux-image-4.15.0-34-generic

I was able to but into it, however my 2k widescreen monitor isn't recognized in the settings when I boot to the generic kernel. How to I even begin to solve this problem without messing with the working low latency install?

UPDATE: it appears that all networking is down too.

UPDATE 2:

I was able to access more settings in nvidia x-server settings and the default display changed to my external monitor (the internal display was no longer recognized...) by installing 4.15.0-38 and the following packages:

linux-headers-4.15.0-38-generic
linux-modules-4.15.0-38-generic
linux-headers-4.15.0-38

I feel like this is the right direction, but what other packages will I need and is there a tool that makes this easier?

So I need to reload my profile after making changes (this time due to a typo). I run source ~/.profile and everything works perfectly fine.

However the source command only applies to that terminal session. This means I'm running the command every time I open up a new terminal. I want to find a way to apply the .profile/environmental variables to the entire user session without logging out, not just the current terminal.

Is there a package or command that can execute this type of change by reloading the profile like it loaded on login?

EDIT: To clarify that it is not a duplicate I don't want to use:

source ~/.profile

or

. ~/.profile

As they only effect changes on one terminal session. I want to effect changes across all started terminals from my user session. I already have changes in the current terminal session using those commands. I need them in newly opened terminal after I run the command (which to clarify I don't currently have. the changes are only effecting the current terminal and my question is to effect these changes across multiple terminals

I'm using SoftEther, but that may be irrelevant.

I have the following adapter:

vpn_myadapter: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet6 [redacted]  prefixlen 64  scopeid 0x20<link>

and I have the following routes:

I need to know how I can easily use Ubuntu to route all internet traffic through my VPN adapter.

I used lsof | grep home/$USER and I found that the gmain process likes to open my personal files. What does this process do and is there any available documentation that explains it in context of Ubuntu?

I'm having an exceedingly difficult time resolving dependencies for Unreal Engine on Ubuntu 16.04 LTS. I'm now being presented with a dilemia which appears to require me to either remove numpy or give up my installation for Unreal Engine. Can someone please explain how I can potentially resolve this issue as I will be using both. Here is the log from aptitude when I'm installing a dependency for clang-3.8 known as libblang1-3.8. In short, clang-3.8 and its dependencies are the issue:

The following NEW packages will be installed:
  libclang1-3.8 libobjc-5-dev{ab} libobjc4{ab} 
0 packages upgraded, 3 newly installed, 0 to remove and 0 not upgraded.
Need to get 4,624 kB of archives. After unpacking 18.4 MB will be used.
The following packages have unmet dependencies:
 libobjc4 : Depends: gcc-5-base (= 5.3.1-14ubuntu2) but 5.4.0-6ubuntu1~16.04.6 is installed.
 libobjc-5-dev : Depends: gcc-5-base (= 5.3.1-14ubuntu2) but 5.4.0-6ubuntu1~16.04.6 is installed.
                 Depends: libgcc-5-dev (= 5.3.1-14ubuntu2) but 5.4.0-6ubuntu1~16.04.6 is installed.
The following actions will resolve these dependencies:

     Keep the following packages at their current version:
1)     libclang1-3.8 [Not Installed]                      
2)     libobjc-5-dev [Not Installed]                      
3)     libobjc4 [Not Installed]
