刚刚在测试VirtualBox服务器上使用RHEL6DVD进行了新的安装:
[root@bt-rhel6-1 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.1 (Santiago)
我确信这是一台x86_64机器:
[root@bt-rhel6-1 ~]# uname -a
Linux bt-rhel6-1.local 2.6.32-131.0.15.el6.x86_64 #1 SMP Tue May 10 15:42:40 EDT 2011 x86_64 x86_64 x86_64 GNU/Linu
好吧,我重新启动了我的电脑,有些不一样.我的Wifi连接面板不见了!好像我再也没有无线适配了!
📷
奇怪的是使用lshw确实能检测到适配器..。

如果我做了一个apt-get upgrade,我会得到以下错误:

我为实现循环编写了以下代码
*// roundrobin.cpp:
#include <iostream>
using namespace std;
int main()
{
int numpros;
int temp=0;
cout<<"enter # of processes=";
cin>>numpros;
int twt=0;
int* wt=new int[numpros];
int* bt=new int[numpros];
int* eqs=n
我正在为Linux2.6.39内核做系统调用。
我已经完成了文件中的所有编辑。现在,当我试图编译内核时,它显示了这个错误:
错误: stdio.h:没有这样的文件或目录
如果我删除stdio.h,系统调用会工作吗?
我的代码是
#include<stdio.h>
#include <linux/linkage.h>
asmlinkage long sys_atvfcfs(int at[], int bt[], int n)
{
int i=0;
int j,t,wt[n],sum,q;
float avgwt;
for(j=i+1;j<n;j++)
我正在为FCFS调度编写这段代码。但在Linux中,这给出了“分割错误”。如何纠正这样的错误?
#include<stdio.h>
#include<string.h>
float fxn();
int main()
{
float avgwt;
int n,i,at[10],bt[10];
printf("\n\nEnter the number of processes:");
scanf("%d",&n);
printf("\n\n BURST TIME and ARRIVAL TIME of thr proc
RTL 8822 the驱动程序有一些问题。我已经有了内核4.14 ( https://www.phoronix.com/scan.php?page=news_item&px=Linux-Realtek-RTL8822BE )。但似乎有一个问题:
$ lspci -knn | grep Net -A3
$ rfkill list all
1: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Ha
除了降级之外,还有谁知道在升级到内核4.0之后修复TP-Link Tl821N无线连接的解决方案?没有无线适配器的信息。
kde中的网络图标是红色的,wifi连接不出现在菜单上连接,无法连接到Internet。
