## Teamviewer on Jetson nano: CheckCPU: unknown architecture aarch64

I’ve installed teamviewer on Jetson nano following this instruction. It fails in two ways:

• if I launch it from command line, i get following output:
  Init...   Error: CheckCPU: unknown architecture 'aarch64' 
• if I connect to it after setting password through command line, it allows to enter login remotely, but after entering password it immediately disconnects.

I tried changing WaylandEnable /etc/gdm3/custom.conf, but it doesn’t help. What else can I try?

## How do I compare different optimization algorithms when step-size is unknown?

I wish to compare different optimization algorithms (gradient descent, Newton, quasi-Newton, conjugated gradient, etc) for a particular problem at hand. My main focus is on speed of convergence.

The issue is that all methods rely on a step-size $$\gamma$$. How do I compare the speed of my algorithms when I don’t know which $$\gamma$$ would work best for which model?

## unknown filesystem error while trying “Insmod Normal”

I tried to uninstal Ubuntu 16.10 from my windows 7 and install 18.4. Deleted the volume but the partition was active. I restarted the system after which it is opening under “Grub rescue”. All commands are working except “Insmod Normal” and “Normal”. So my system is completely stuck. I am neither able to fix Ubuntu nor I am able to fix Ubuntu. Please help!!! Need an urgent fix.

## Unknown process attempted to execute code

This morning I booted up my computer and not long afterward, got a notification from ByteFence (unsubscribed) that an unknown process attempted to execute a command that was deemed unwanted. ByteFence gives me the option to ignore the “threat” and let it execute, but to Block it, I need to pay for their service.

I don’t recognize the filename, and a quick Google search didn’t turn up any results that were helpful… mostly just weird looking results that look like garbage text. Here is the message from ByteFence:

As you can see, the executable name is “ryiddps.exe”. And the parameter after does seem unusual. I killed the process in Task Manager and deleted the executable, as well as its parent directory, and it hasn’t yet re-appeared (in case it’s self-replicating), but I don’t know whether the damage could already be done, assuming this executable was, in fact, malicious.

Anyone have any ideas what this application was trying to do, or possibly recognize the application name? I’d like to dismiss the damn ByteFence notification, as it’s stealing focus from all other applications, but I don’t know if I should click Ignore.

## Unknown error while running a “graphics.h” program in Ubuntu 16

I wrote a code on Bresenham Line drawing algorithm,and when i tried to run it,i got this error:

[xcb] Unknown sequence number while processing queue [xcb] Most likely this is a multi-threaded client and XInitThreads has not been called [xcb] Aborting, sorry about that. a.out: ../../src/xcb_io.c:274: poll_for_event: Assertion!xcb_xlib_threads_sequence_lost' failed. Aborted (core dumped) 

My Code:

  #include<stdio.h>   #include<graphics.h>  void main() {  int x1,y1,x2,y2,dx,dy,p;  int gd=DETECT,gm;  initgraph(&gd,&gm,NULL);  printf("Enter the values of x1,y1:\n");  scanf("%d %d",&x1,&y1);  printf("Enter the values of x2,y2:\n");  scanf("%d %d",&x1,&y2);  dx=x2-x1;  dy=y2-y1;  p=2*dy-dx;  putpixel(x1,y1,3);  for(int k=0;k<dx;k++);  {      if(p<0)      {          x1++;          p=p+2*dy;      }      else      {          x1++;          y1++;          p=p+2*dy-2*dx;      }      putpixel(x1,y1,4);      delay(100);  } }    

## Unknown app. Left after getting rid of about 5 others!

Fresh install, I go to Logitech to get app for my mouse. Popups for driver cleaners etc. Easy to find but one it seems loaded from common files to my services and secure like some are, as not to disable, right. Well I get the file name and nowhere is there a hint of it! ” ForeignHopeJKEye” This is the one that is an anomaly, It is an .exe type but can not figure its function, in my Services!

I want to get into the computer but I can’t seem to remember what to put in. I have tried some tutorials on this website but when I press escape nothing happens, except for making a REALLY loud noise. It sounds like a fire alarm. The computer is a very old HP Pavilion Entertainment PC. Any help at all is greatly appreciated!

## mysql: [ERROR] unknown option ‘–sql {‘

## Exploring previously unknown area with a drone algorithm [on hold]

I’m working on a drone platform for mapping indoor environment based on depth and image proccesing.
I’m looking for an algorithm for exploring previously unknown area, something like a house with a few rooms (assuming one floor for now). Cleaning robot exploring style.

For a start, I preferred to use software package/SDK, free/open source, but payment for a good SDK is also considerable.

It can be very naive and non optimized, and can assume 2D problem if it easier.

I google it, saw a lot of academic articles but I need something more practical for a start.

Any suggestion?
Thanks!

## readline: unknown key modifier

I am attempting to set revert-all-at-newline on in my bash config file.

bind 'revert-all-at-newline on' 

However, this throws the error

readline: revert-all-at-newline: unknown key modifier 

bind does not appear to have it

$bind -l | grep revert-all-at-newline$   

But it is in the man readline documentation locally.

How can I get set the revert-all-at-newline` config variable?

• bash version 4.4.2
• readline version 7.0
