when i boot 9legacy I set the resolution as 1024x768 then select [xga]. According to this page http://plan9.bell-labs.com/wiki/plan9/setting_the_right_monitor_size/ 1024x768 is a valid option for xga. However rio fails to start and if I select the default resolution rio renders 3 black windows and the colours are inverted. To view the text in anyone of the windows I have to select another one for the text to appear. Any advice?
