Ubuntu 9.10 Karmic Koala Experince

Last week I mentioned I had one problem while playing around with Ubuntu 9.10.  The problem actually resulted in several problems but they all seem to have been worked out.  I will start with the original problem.  While running an new install using Ubuntu Tweak, Firefox, Terminal, Tomboy Notes and Nautilus the install suddenly locked up.  I started shutting programs down but the computer started becoming unresponsive so I hit the power button, this brought up a warning that all the programs I had tried to shut down were still running so I canceled out of the shutdown.  At this point the computer became completely unresponsive.  I know that hard resets are not advised but was not sure what else to do at this point so did the inadvisable.  (I was thankful the computer was not a production machine but hoped it would survive) I had to do two more hard reset before I was able to log back into Ubuntu.

This is when I ran into the consequences of Ubuntu locking up during an installation.  I went back to the install I had been in the middle of and ran into an error I was not able to install the package.  After trying all the install options including the Terminal plus trying to remove the packages that were giving me an error I had to resort to Sudoing into Nautilus searching for the package that had the error and deleting everything that was brought up.  For example: I had to search "libxcb-shm0" this brought up the .deb file plus a number of text files.  I selected them all and threw them in the trash.  After I did this with all the files that brought up errors I was once again able to install or remove programs.

One other problem I ran into after the lock up was on restart the mouse and keyboard were locked out.  To solve this problem had to power off log into Ubuntu then do a shutdown.  Not sure what caused the lockup but have not had the problem again.  Update after a restart my keyboard and track pad were locked up again.  Finally I had to keep my finger moving on the track pad until the login screen came up.
