Input Signal Out of Range(Specific to Full-Screen Apps powered by PYTHON)

[Josh K]

Full screen python games and programs rendering using 3d graphics on a LCD connected via VGA(giving incorrect EDID data) results in configuration parameters exceeding device capacity.

STEPS REQUIRED TO REPRODUCE:
Obtain an lcd monitor utilizing a VGA input port, or obtain a DVI-VGA crossover cable.
Connect the Monitor to your video card.
Open Frets On Fire and set parameters to Full-Screen : On.
Enjoy your error message.

Can you reproduce the problem (with full screen applications) if you disable Compiz?

[Josh K (terlmann-deactivatedaccount)]

The answer is yes. This issue is program specific. Disabling compiz(which I did) does not effect the full-screen program, as it attempts to directly modify monitor parameters. Also, as for the example program, I was able to check some sites and get a fretsonfire.ini file with a [video] section and place the file in terlmann/.fretsonfire/fretsonfire.ini . With full-screen disabled , the program works fine. This problem effected multiple programs though.

It might be related to the pygame library. What other programs are affected by the problem?

We are closing this bug report because it lacks the information we need to investigate the problem, as described in the previous comments. Please reopen it if you can give us the missing information, and don't hesitate to submit bug reports in the future. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to New. Thanks again!.

This bug is to remain open until solved, as this effects all ubuntu installations and varients. Other programs currently affected include lbreakout and etracer. The likelyness of this being python specific is extremely high.
I will add pygame to the list of effected programs.

I've experienced this problem too.

Programs using pylib work fine in a window, but in full-screen mode they lock up the screen with an "signal input out of range" (sic!). The mode they're being set to is 800x600. The screen becomes useless - the only way I can get the display back is by switching to tty1 and killing the X server.

libsdl1.2debian-alsa is installed. It appears to be a libsdl problem.

One fix is to hack each pygame application. Find the line saying "pygame.display.set_mode((800, 600), FULLSCREEN) and remove the FULLSCREEN bit. This prevents any accidental lock-ups.

Ideally, the X server would refuse to use a setting that doesn't work with the monitor, but the xorg.conf file is now pretty sparse.
