11.0.450 has been disabled by Draftsight. 11.2.015 is so slow it is unusable (even with SNA enabled). So I am now using IntelliCAD again--and it will never EXPIRE.
The mouse cursor problem is most likely related to the version of DraftSight, probably not your Linux or Ubuntu configuration. Due to system corruption caused by a failed kernel upgrade (fixed with sudo apt-get purge linux-image-3.2.0-84-generic) I had to update to a newer version of Draftsight...
