Thank you! That link got me to Joy, but with a hiccup and a bit of a mystery. I quickly found the solution to the hiccup. http://stackoverflow.com/questions/851704/xrandr-errors-badname-named-color-... The line: xrandr --newmode "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync uses the name "1920x1080_60.00", and xrandr no longer likes it. I just used the name "1080p". I am guessing that the "_" is the problem, but I did not test that. I was working from the command line and did the --addmode from there. My display went crazy, and I had to do a soft boot. The system came back in 1920x1080 (!) Joy. I did not have to use the --ouput step, and fix seems permanent. Cheers! -- Stephen
