Installations

Toc generated by markdown-toc.

0. laptop info

1. install the system

1.1 prepare a USB installer - with another computer

Note: official iso (ubuntu-18.04.4-desktop-amd64.iso)

1.2 turn off the secure boot in BIOS

1.3 follow and finish the standard installation process

Note: do NOT set grub (eg. nomodeset) if you can install smoothly. After setting ubuntu’s configuration, you can log into the new Ubuntu system (now, with the core graphics card and drivers)

1.4 agree the 1st time update require, then reboot

Note: when you first get into the Ubunutu, you may get a piece of update information, DO agree that, the principle is that we agree with all updates during the process of installation, but after we get a stable and complete system, then we stop update anything, try to keep the system having no change, if not, there might be some conflict between the new updates and the old drivers.

2. install nvidia dirver

2.1 add repository then we can check devices

Note：we get the recommendation version here！

$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt-get update
$ sudo ubuntu-drivers devices

2.2 install drivers in APP - Software and Updates

Software and Updates ->
    additional drivers ->
        select the recommandation version ->
            apply

2.3 do NOT set blacklist of nouveau or set grub.

Note: all stuff could be handled automatically by system if we use this way to install the drivers, we do nothing then it would be worked very well with Nvidia drivers!

Now, the installation of the Nvidia driver was finished. You can use nvidia-smi to test if it’s ok (screenshot:http://i.imgur.com/GgfSqCM.png) or just check the system information and see the drivers name. (screenshot: http://i.imgur.com/Euj6tQy.png)

3. install cuda-toolkit

3.1 select cuda-10_* or another version

(screenshot: http://i.imgur.com/6xPtxju.png)

3.2 execute

$ sudo chmod 777 cuda-10_\*.run
$ sudo sh cuda-10_\*.run

type NO in the process

Note: we have installed the driver by ourselves, so here say no.

Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 410.48?
(y)es/(n)o/(q)uit: n

3.4 test samples

$ cd /usr/local/cuda/samples
$ make
  (10 minutes later)
$ cd /usr/local/cuda/samples/bin/x86_64/linux/release
$ ./deviceQuery

(screenshot: http://i.imgur.com/jJ7vpNw.png)

3.5 extra IMPORTANT config

Note: add two environment params into /etc/profile, if not, maybe you could get the error says: libcudart.so.10.0: cannot open shared object file: No such file or directory

export PATH=/usr/local/cuda/bin:$PATH 
export LD_LIBRARY_PATH=/usr/local/lib:/usr/local/cuda/lib64/

Now cuda installation is finished, actually, with samples’ test, we can also make sure that the GPU driver worked well.

4. install GL stuff

4.1 for GL/gl.h use

sudo apt install mesa-common-dev

4.2 GL/glu.h

sudo apt install libglu1-mesa-dev freeglut3-dev

4.3 others

libglfw3-dev libgles2-mesa-dev libglew-dev

4.4 just use all-in-one command

Note: they are all necessary to install, and maybe you need to install more libs, it’s up to your code.

$ sudo apt install mesa-common-dev freeglut3-dev libglfw3-dev libgles2-mesa-dev libglew-dev

5. install project stuff

5.1 base tools

$ sudo apt install vim
$ sudo apt install cmake

5.2 rebuild project

$ cd ProjectionExplain/LIBRARY/glui-master
$ rm CMakeCache.txt
$ make clean
$ mkdir build && cd build
$ cmake ..
$ make install
$ cd ProjectionExplain/
$ make clean
$ make 
$ ./projwiz -f DATA/segmentation lamp

All stuff about GL-project has been done! (screenshot: http://i.imgur.com/rDCtEId.png)

6. install personal software

6.1 screenshot: flameshot

use sudo apt-get install flameshot

set the shortcut (screenshot: http://i.imgur.com/id2PPYj.png)

6.2 vscode

..more settings could be found in chapter 8.5..

install it directly in APP (Ubuntu Software). (screenshot: http://i.imgur.com/W971ERc.png)

then, we can program code with vsc

X. Ubuntu Using Tips

X.1 updates

just delay the update checking (I don’t know how to stop it)! do NOT cancel the ‘update from’, or you would get errors when you install new packages/tools/… (screenshot:http://i.imgur.com/w7Kvc7X.png)

X.2 when desktop crash

like stucking when turning off some windows or stucking after running something for a long time. When this happened, do NOT shut down the system by cut down the power! that’s a dangerous behavior, system core may be ruined by this.

the right way is: Ctrl+Alt+F2/3/4, log into the tty2/3/4, then restart gdm/lightdm, or rollback the wrong options here if you remember. Or do nothing, just wait for the system rerun again, sometimes it could be reworked after waiting a while.
