Installing Nvidia Driver in Ubuntu Secure Boot

*DISCLAIMER:- most of the images were taken from the internet. It is troublesome to simulate back the problem just to take original screenshot with the intention only to make a note.

1. My laptop is Lenovo Y510P with Nvidia GeForce GT 755M using Ubuntu 20.04.
   
   
2. After one of the updates, ubuntu failed to use Nvidia and instead it used Intel graphic.
   
   
3. The Graphic status at Settings -> About is stating Intel Graphic.
   
   
   
   
   
4. The X Server is also not working correctly. Eventhough I select NVIDIA, the Graphics column in About was still stating Intel graphics. Also, many items was not displayed. It displayed
   
   
   
   
   Instead of
   
   
   
   
   
5. The nvidia-smi command prompt also produce the following error.
   
   
   
   
   
6. There are two ways to solve this problem.
   
   
1. Easier way - disable secure boot.
2. Medium - Reinstall nvidia-prime, then ubuntu-drivers-common and run prime-select nvidia
   
3. Hard hell - reinstall new driver
   
   
7. No need to explain the secure boot. You just need to disable it in BIOS.
   
   
8. I use the solution in here. There are many ways stated here but the one I use is at the Section 4 under UEFI System.
   
   
9. Download the latest driver at Nvidia Official site. Please check whether your graphic card is supported in Supported Products tab after you are redirected to download page of the selected driver.
   
   
10. After I was done with solution in the page I shared at point 8, I check at the About, X Server and nvidia-smi command, everything is good.
    
    
11. About in Settings
    
    
    
    
    
12. X-Server
    
    
    
    
    
    
13. nvidia-smi command

Setting Up DLNA and Samba at Huawei Router

 

1. I faced few problems during setup a home network storage using the router Huawei B618s-65d as below. This storage is only an external HDD attached to the router.
   i     - accessing samba using GUI window explorer
   ii    - transfer more than 2 GB files 
   
   
2. I also setup the samba when I already setup the DLNA because I will need to transfer my files to the storage without the need to remove the external HDD from router, plug to my laptop to transfer files then plug back to the routers.
   
   
3. After complete setup the samba and DLNA, I try to access the samba using GUI explorer.
   
   
   
   
   
4. However I got the error pop up as below.
   
   
   
   
   

   Unable to access location
   Failed to mount Windows share: Software caused connection abort

   
   
   
   

   First Problem - accessing samba using GUI window explorer
