I recently changed my root version from 6.02 to 6.10, and I found the resolution of TBrowser is much better in 6.10. However, since I always working by log in to some remote server, the time for generate the TBrowser is also significantly increased. The resolution for 6.02 is good enough for me, is there a command to degrade the resolution in 6.10 thus I could open it faster? Thanks.
ROOT has no control on the resolution, the only thing you can try is to change the font to be used by the user interface. To do so, edit your $(ROOTSYS)/etc/system.rootrc or your custom $(HOME)/.rootrc, and set the value of X11.UseXft to no:
