I have an old laptop (Vista originally) with 64-bit 13.10 on it. Everything works for the most part except the screen. The screen is extremely dim, but it is readable in the right lighting conditions for short periods of time. I didn't think it'd be worth it to fix the screen issue, so I'm using it as a media player hooked up to my TV via VGA. Whenever I turn on the computer, it tries to extend the display and then all the main icons, etc. are on the laptop display, which is not useful.
Also, it doesn't natively support 720p as a resolution, so whenever I turn it on, I manually add 1280x720 (see code) and then select it, also turning off the laptop's display. In some reading I did earlier, it sounded like persistent changes were easier in earlier versions of Ubuntu, but now I can't find the methods to do that. If I have set the 720p resolution and then restart the computer, it tries to do 720p, but then can't and shows an error message. When I click "OK" on the error message, my screen goes black and then resets to the previous default (not sure why it has to go to black and then reset?).
Basically, I would like to permanently set the default display settings to using the external monitor with 1280x720 (not typically on the display settings menu) resolution and the laptop's display off. How do I do this?
Current code I use to add the 1280x720 resolution:
Code:
xrandr --newmode "1280x720_60.00" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync
xrandr --addmode VGA-0 "1280x720_60.00"
