I just tried the current "nightly" builds on a fresh Ubuntu Quantal and it seems there are still several major problems left. I'll describe my experience. When TDM started up, it gave the following error: Cannot open theme file /opt/trinity/share/apps/kdm/themes/kubuntu- trinity There was also a process called tdm_greet using about 99,8% of my CPU. I then shut down tdm thought the init script. I symlinked kdm to tdm in the above path and this problem went away. I got a nice login screen, but I was unable to type anything in it at all! I could click on things, but couldn't use my keyboard at all. I wanted to test a bit more, so I started another X11 server and ran the starttde script in it. This got me to the desktop, but with a kicker process using 100% of my CPU and I couldn't do anything till I did a kill -9 on it. Are these problems known or should I report them and try to get more information? How stable should the current nightly builds be expected to be?
