Ubuntu: TV-out with nVidia card
Posted: Sat Apr 28, 2007 9:56 pm
Here's a bash script that turns TV-output mode on/off using nvtv (a tool for nvidia based cards).
It's based on info from another nvtv HowTo, with minor modifications (Different overscan parameter - I prefer "Huge" instead of "Normal", since this utilizes my TV better by cutting some of the edges)
Some things I've learned:
- Switching your X server resolution using Ctrl+Alt+[+|-] will not work properly for fullscreen displaying of e.g. movies, since you will be able to scroll within a virtually bigger desktop.
(e.g. virtually it stays at 1280x1024, but you only see a range of 800x600)
- "xrandr" can be used to switch the resolution of your X server without the necessity to restart it. I was really amazed to find that it's really intuitive that it doesn't only offer explicit resolutions as parameter, but also accessing the indexed resolutions from xorg.conf. Example:
xrandr -s 1280x1024 -or- xrandr -s 0
Second syntax makes it possible to switch to your default resolution, no matter what it is.
