After a coupe days of searching I finally came to a conclusion. The reason I was getting the purple background was the file that Ubuntu tweak was using as the login background was no longer existent.

It happened to me as well in both Xubuntu 14.04 LTS and Lubuntu 14.04 LTS running on VMware player 3.1.4 build-385536. It seems a kernel issue that is not yet sorted out.

I did 2 things to fix it: In lightlocker (Menu>Preferences>Lightlocker) make sure that 'blank screen' and 'switch off display after' are set to 'never'. Then make sure the 'Enable Lightlocker' switch is OFF. In XFCE Power Manager (Menu>Preferences>Power Manager) select the 'On AC' menu, then click the ...

After some tinkering I found a simple solution for the Dell computer and there should be a similar solution with other laptops as well.

I have found a solid answer on another branch of StackExchange server(s). It's a rather complicated procedure and I have not tried it yet. Also it seems to not apply to the (virtual )terminals( -- Those under Ctrl+Alt+F1...F6), which is to be verified.

The answer provided by chaos is very informative. However, even after following those instructions, I still had this problem intermittently. There is some sort of background process or settings manager that keeps resetting the screensaver, no matter what I do. I've found a brute-force solution. Just add a line to your crontab to turn off DPMS and the ...

I am new to linux too. I would go back to the download page of the distro you have selected and check the checksums I think it's called MD5. Most times before you burn the iso the burner shows you the checksums and you should check if they're the same number. It could be a corrupt iso from a download. I had a problem similar but the difference was it would ...
