I have a rather unusual problem and would be very grateful for any pointers in the right direction.
My Ubuntu machine is hooked up to my tv via dvi-to-hdmi cable. Now while trying out XBMC, a great media media center solution, my tv suddenly looses its signal after a while. This happens quite nondeterministicly. It just goes blue, as if I would have changed the resolution to an unsupported one.
Of course I checked the logs of XBMC, but nothing unusual was happening there. Actually nothing at all happened at the moment the screen would go blue…
The thing is, it seams to be related to OpenGL. Glxgears would produce the same effect!
That’s where I’m stuck, I’m afraid What could OpenGL be doing that would cause my TV to protest? It isn’t the resolution that’s being changed, but the effect is the same (tv goes blue on me). Would it be possible that the refresh rate is being changed on the fly? How would I go about to confirm something like that?
It’s a long shot, I know
Thanks a bunch!
