Vga loss

[steve.warnes]

Hi

Brand new to this.

Finally installed Linux Lite onto spare machine to use as a backup  for other PCS and maybe a server.

I have my main machine and the linux lite machine feeding to one monitor through a vga switch.  since installing linux lite when I switch to my main PC and then back to the linux lite machine I have no display.  This wasnt the case when I ran Windows on the old machine.

Can anyone give me a fix?

Cheers

look at the end of /var/log/demsg text file for any reasons.

Code:

cat /var/log/dmesg

or

Code:

sudo dmesg |  tail

I guess. But I would rule out a faulty vga switch first if me in your shoes. Since that is easy to do. Just disconnect from vga switch to screen and hook direct while screen is blacked out.

Hi Thanks

I tried pluging the vga lead in directly and that didn't work.  I have used that code to look at that file but there is a lot of it and I dont know what it means.  I have attached the code.

Somebody with a more sharper linux skill set needs to step into this thread from here on in.
