Perhaps RHEL/CentOS 7 are something different, however, they just change a little, their base used are similar. On a gnome desktop, if you want to add a shortcut to the desktop, you can reference xxx.desktop in /usr/share/application/ , than write some similar xxx. desktop which you prefer and cp to the desktop directory ? it's really useful.. ------------------------ Best wishes -----------

hi all, I've inherited a server with CentOS 6.4 the VNC Server starts up with the OS and its screen resolution is set to 800x600. I found that I can set the resolution by specifying the -geometry switch, but I can't find where the call to start the vncserver is set in order to change it. I know that it's not in /etc/xinetd.d (the only file there is rsync) here are the contents of

hi all, I've inherited a CentOS 6.4 machine that runs VMWare Workstation 9 which in turn hosts a Windows SBS 2011 guest. the problem is that the Windows guest keeps crashing, and I have no idea why. it was working fine for a while but recently started crashing after a day or two of operation. as a total Linux/CentOS noob, I have some questions: 1) is it safe to assume that since the guest

hi all, after many years of working almost exclusively with Windows servers I am trying to switch to CentOS. I have a couple of books which were written for CentOS 5, but many (basic) things do not apply to CentOS 7 anymore, which is very confusing.

Hello all, I'm trying to modify a single column of a data frame to remove randomly half of the values. I want to do it within a function, but can not assign the modified column back into the data frame. It was easy and successful without a function, so I suspect the problem is the call of the single column within the function. removedata<-function(datafull,var.removed) { attach(datafull)

Hi, I'm trying to perform a glm model on count data (poisson distribution of the errors) where data are nested. glmmodel<-glm(y~x/z,poisson) x and z are factors, z nested within x, y is count data. In that point the R just "stuck" and not respond anymore. I tried glmmodel<-glm(y~x,poisson) and there were no problems. Trying glmmodel<-glm(y~x/z) gave the same no response.

Hi, I'm in need of rebooting a server 1 minute after I give the command. I'm used to shutdown -r +1 which works as advertised.
