The steps I carried out to detect where the problem was were as follows: 1. Checked whether basic plots in R worked 2. Created a new UID ( which did not have my saved settings in R) and tried basic plots.
If 2. told me that margins were too large, then this was not a problem due to my past commands in R. xorg.conf is a dangerous file to meddle with. The other symptoms I was seeing of poor graphics was an XL font size on my login screen and broken images in google earth. Are you seeing anything of the sort? I am relatively new to the mailing list. Do tell me if this is better taken offline. 2008/11/15 megha patnaik <[EMAIL PROTECTED]> > Hi John, > > I had struggled with this myself, and investigation revealed that it isn't > an R problem, but an X11 bug in Ubuntu.
