I'm using compiz and tvtime, and usually everything works fine. However, when there are many applications running (many windows), then tvtime will quit when trying to switch to fullscreen mode:
Cannot allocate enough off-screen video memory.
This may be fixed by:
1. Closing or restarting large X applications.
2. Lowering the input width of tvtime (--inputwidth parameter).
3. Lowering your colour depth or highest configured resolution.
4. Increasing the amount of video memory in your X config file (for example, if you are using the i810 XFree86 driver.)
It worked again after closing some applications. Is there a way to always ensure there is enough offscreen memory so that tvtime will always be able to switch to fullscreen?
