Honored ContributorI don't think tcl/tk font scale accept a negative value. please confirm manual.
As for the control file, according to the modelsim command manual, they might be .modelsim or modelsim.ini. pref.tcl might be possible, I think. As for the negative font size specifying, I found the behavior has been quite strange via editing the preference menu(by name). So I recommend editing default textfont size of $HOME/.modelsim file to the negative value(such as -12 or -10), and don't touch. I think you can specify any fixed font as you wish. I'm going to test these settings. My environment is Ubuntu16.04_64 and CentOS7.2_64. On CentOS, all defualt fonts were specified by negative value at first, but preference menu does not show negative value on the menu. The behavior is slightly strange. I guess this is also some trick by Altera or Mentor. That's why I think it might be no use to reinstall fonts or libraries.
