After googling that error, it appears to be a display manager issue. I believe Ubuntu now uses GDM3, so you could run
dpkg-reconfigure gdm3
in a terminal. It’s been a couple of years since I’ve come across this and don’t really want to see you bork your system at this stage. If you can make it work for you it’s best not to rock the boat until you are more comfortable with it. It may well resolve itself next month when 19.10 comes out.
Thanks ! I know how to install it now so no problem if i mess things up
I tried that command but its saying it needs to be run as root ? I tried typing root and enter but no luck
Sorry, that should have been:
sudo dpkg-reconfigure gdm3
Sudo temporarily elevates your privileges and allows the command to run.
Did that, then entered my password then clicked enter, rebooted and no luck.
Lets hope its fixed in the next update 
Thanks anyway mate
On a site on Google it says to use the “lightdm”. Command as opposed to gdm
Although this is for an earlier version of Ubuntu
Every six months a new version comes out right? I won’t lose my files or anything will I?
Yes, that’s right --usually April (the .04 release) and October (.10 release), but you shouldn’t lose your files.
With that said, it’s always prudent to keep a backup of your files, regardless of the OS you are using. If I recall, there’s a backup utility pre-installed in Ubuntu, but if not there’s bound to be one in the software centre.
There are some Linux distributions that take a more rolling approach, so the packages that are available are always the latest ones, but that can cause issues of its own.
Great. Thanks for all the info guys i’m now a happy but n00b Linux user
Installed clam av and It just hangs when trying to scan
Also tried Sophos, but it has no GUI 
@GarethTheNerd dude do you use an anti virus on linux or not ?
Nope, I don’t. I’ve never even tried one 
Ok man thanks.
Got the anti virus working, w00t.
I’ll keep quiet for now lol as all is ok 
Considering going back to Windows now I have a new PC
Mainly because I’m getting screen tear on movies and gaming probably due to the lack of drivers for my GPU.
For some reason AMD only make drivers and software for Windows
Suppose I could try out W10 again on my new PC and if i dont like it then go back to Linux
Only thing is I like linux’s speed and security, its a difficult one
Not quite --linux handles drivers differently to Windows. There’s a guide here:
Unlike Windows, you don’t need to download and install drivers from the AMD website, Ubuntu will pull them down for you, but they’re not usually installed by default.
Thanks dude.
After some research and terminal coding I managed to completely get rid of the screen tear
Looks like i’ll stick with Linux
When is 19.10 out, it’s supposed to be today ?
If it’s supposed to be today, either it’ll be today, or it’ll be later.
Still nothing
If it is being released US-time, as does Apple, it’ll be after 6pm here. However, there’s nothing stopping you installing the latest beta version as it’ll amount to the same thing.
Its available now, thanks
Any reason why you’re so keen for 19.10?
Nope just fancied an upgrade lol.
W10 is my main OS, just use Linux for messing about with
When is the next Ubuntu coming out ? Not the lts version, I mean the one after 19.10?
