This How To will explain and fix the nouveau graphics weirdness that has plagued VSIDO from the beginning. For whatever reason, nouveau caches images in the memory of the card and when logging into VSIDO, you can get some interesting rainbow looking screens that last just a second
This How To will show you how to fix it.
This has to be run outside of Xorg and lightdm so first exit everything, logout and then and drop to tty1
ctrl + alt + f1
Next we need to kill lightdm and Xorg
sudo systemctl stop lightdm
Next we need to create an xorg.conf
sudo Xorg -configure
This copies it to /root/xorg.conf.new and we need to copy it to X11 this way
sudo cp /root/xorg.conf.new /etc/X11/xorg.conf
That's all... just reboot with
sudo shutdown -r now
and Profit!
You should never see the graphics bonanza again...
