The gripe about 24bpp being "not permitted" looks wrong, unless there's
not enough video memory allocated.
Having different failures for different users strikes me as very odd.
It rather suggests a permissions problem, but permissions aren't
mentioned in the logs.
If you can think of something to test please instruct.
Thanks for reading,
