which version of lxle?

open a terminal and type

sudo dpkg-reconfigure xserver-xorg


then reboot

Here's an update. I did the sudo dpkg-reconfigure xserver-xorg command in a terminal window. It asked for my password and I did it. It went to another prompt. So i closed everything and rebooted. I know it did some updating when it was rebooting. The resolution which I had set in ARandR screen layout editor was 800x600. When I rebooted it had reverted back to 856x600 so the screen runs off the page. Back when I was running Lubuntu I had the exact same issue but was able to correct it by adding the line '$ xrandr --output default --mode 800x600 --rate 60' to the /etc/xdg/lxsession/LXDE folder and it worked great. I tried it on this one and it didn't work. So i thought perhaps beings I'm using the XP-Paradigm, perhaps it would work if I put i put it there in autostart.conf file. That didn't work either. So i've now removed all those changes and am back where i was. If you need any more info I'll be happy to provide it. Thanks

There is a file in the XP-Paradigm folder that is autostart~. Do i have to change the name of it or just leave the tilda at the end?

I followed the path and found a file called autostart~ with a ~ after it just like that. Is that the file? I edited that one with the line you said to add but it had no effect. That's why I asked did I need to rename the file to autostart.conf or something or take the ~ off the end.
