说明:win11+ubuntu18.04
Alternative downloads | Ubuntu
得到文件:ubuntu-18.04.6-desktop-amd64.iso
Rufus下载地址:Index of /downloads
https://github.com/pbatard/rufus/releases
得到文件:rufus-3.17.exe(版本不固定)
查看win11的BIOS模式:
键盘按win+r,输入msinfo32,可以看出本机为:UEFI
双击打开rufus软件,进行如下选择:(u盘会被格式化,注意备份)
准备就绪后弹出u盘,准备插到新电脑上。
win11的:搜索--磁盘管理,给win11留100G
搜索--控制面板--硬件和声音--更改电源按钮功能--更改当前不可用设置--(取消勾选)启用快速启动--保存修改。
插入准备好的u盘;
重启,按下F1,进入界面:
选择More Settings
secure boot从disabled改为enabled
First Boot Device由Boot Order改为USB HDD。
修改这两处后,按下F10,保存并退出。
上面保存并退出后会进入安装界面
选择第一个Try Ubuntu without installing或第二个Install ubuntu均可;选择第一个之后会进入ubuntu界面,在桌面上就有一个指向“install ubuntu”的快捷方式,同样可以进行安装。
这里选择第二个 install ubuntu,接下来是安装步骤
选择英语(也可以选择chinese),安装完成后也可以调整系统语言
选择正常安装:Normal installation和Download updates while installing Ubuntu
选择something else,和win11所在磁盘分开。
下面是进行磁盘分区,考虑到/boot和/swap是必须的分区,这里将共分为三个分区/boot、/swap、/。
这里/home是存储用户个人文件的,一般意义上的“/”分区是存放计算机文件的,这里没有进行区分,具有较大的灵活性。能够让避免一开始给/home分区分的空间太小后来不够用且“/”分区有较大空闲----导致的空间利用率不高问题。
选中win11系统下划分的空闲磁盘分区:
点击左下角的“+”号,创建/boot分区。选Logical+Beginning of this space+/boot。
有的博客说的100MB够用,这里主要存放ubuntu系统的引导文件,有时候不小心点到的ubuntu更新,就会增加一些内核在这个位置,到时如果/boot分区满了,可以删除不必要的文件。我这里设置了500MB,一般200-300MB应该够用。
点击"+"创建/swap即交换空间分区,一般设为内存的2倍(让内存有时间休息下来,类似一半干活一般休息的意思)。我的内存为16GB,这里分区设为32GB=32768MB。选 Logical+Beginning of this space+swap area。
点击"+"创建“/”,将剩下所有空间都给“/”。选Primary+Beginning of this area+/
选择ubuntu安装引导分区即前面分的/boot分区,在下图的最后一行。弹出窗口后选择continue
选择地区,这里选了上海,其他地方应该也行
设置用户名、主机名和密码。注意用户名/主机名可以不一样,因为安装完系统后不容易修改,尽量这里设置一个比较合适的名称;密码尽量不要太长,因为进入系统后有很多需要输入密码的地方,太长容易耽误时间。
接下来就是等待安装了:
安装完成后会弹出这个界面,不要重启,“×”掉,然后选择关机;关机后将u盘拔掉,再开机。
开机界面如下,说明安装成功了
安装主要参考:ubuntu18.04安装ROS Melodic(最详细配置)_抚琴弹出情凋零的博客-CSDN博客_ubuntu18.04安装ros
下面是我安装过程遇到的问题:

#sudo ./NVIDIA-Linux-x86_64-396.18.run -no-x-check -no-nouveau-check -no-opengl-files
#下面是最后依次成功尝试的,没有加任何选项
#sudo ./NVIDIA-Linux-x86_64-396.18.run
安装过程选项如下:
重启
sudo reboot
根据师兄建议,选择了一个不是很新的11.3版本,下载链接:
CUDA Toolkit 11.3 Downloads | NVIDIA Developer
选择类型进行下载
下载完成后安装:
chmod +x cuda-xxx.run
sudo sh ./cuda_11.3.0_465.19.01_linux.run
安装选项如下:
continue
accept
按下enter,勾选掉Driver
选中install并按下enter
安装后的目录等如下:
cd /usr/local/cuda/samples/1_Utilities/deviceQuery #由自己电脑目录决定
sudo make
sudo ./deviceQuery
找到下面两个目录,在终端输入命令即可
# 将cuda加入~/.bashrc
export PATH=/usr/local/cuda-11.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-11.0/lib64:$LD_LIBRARY_PATH

前面安装了cuda11.3,在上面网页中没找到,于是下载了一个for cuda 11.x
没想到下载下来的文件名里面居然有11.3,不知道为什么
将下载文件解压,进入解压目录
------------ /usr/local/cuda-11.3/
sudo cp cuda/include/cudnn.h /usr/local/cuda-11.3/include
sudo cp cuda/lib64/libcudnn* /usr/local/cuda-11.3/lib64
sudo chmod a+r /usr/local/cuda-11.3/include/cudnn.h
sudo chmod a+r /usr/local/cuda-11.3/lib64/libcudnn*
因为cupy-cuda113版本过高不能适应一个网络问题,重装cuda为cuda-11.0。
卸载cuda
cd /usr/local/cuda-11.3/bin/
ls #查找卸载工具
sudo ./cuda-uninstaller
删除文件:
cd
sudo rm -rf /usr/local/cuda-11.3/
过程参考:6.3
chmod +x cuda_xxxx.run
sudo sh ./cuda_11.0-xxxxxx.run
#xxxx代表版本号
过程参考:6.4.2
参考链接:How to Install Indicator SysMonitor on Ubuntu & Debian - TecAdmin
sudo add-apt-repository ppa:fossfreedom/indicator-sysmonitor
sudo apt-get update
sudo apt-get install indicator-sysmonitor
然后就在右上角出现这个使用率
将鼠标放到上面箭头指的cpu位置,会出现一个下拉框,点击preference,选择advanced,添加 net:{net},即可(下图第一个箭头处有空格)
最后配置效果如图所示:
格式为.rar的文件直接解压缩会提示错误,需要安装包:
sudo apt-get install rar
sudo apt-get install unrar
解压缩效果如下
执行下面的命令安装即可
sduo dpkg -i xxx.deb
如运行python文件,在扩展里面搜索“python”,安装,可以实现python代码的补齐和跳转
