I created a custom ISO with remastersys, i installed the ISO on a laptop yesterday. The log in screen was working fine. After I downloaded 20mb of updates on 12/7 and rebooted, the log in screen was corrupt. The background was black, and the icons on the top bar were 'low graphics' icons. I tried to run the command do dpkg-reconfigure lightdm, but it gave 2 erros with missing packages. The only visible part was the username box.
I don't want to reinstall a clean 11.10 and I want to fix the log in screen. I am able to log in and 11.10 runs fine but I'm unaware if the problem was me using Remastersys.
