Since upgrading the graphics card on my X1000 to a R7 250X (SIl), with the Radeon HD 2.7 driver, my AmiCygnix installation either starts with graphical corruption or crashes when I try to load an application (eg, AbiWord).
I suspect my X11 environment isn't set up correctly to work with the new graphics card.
Does anyone else use AmiCygnix on an X1000 with this card and, if so, which settings work?

It's a known problem. AmiCygnix uses 16-bit screenmodes, but expects a big-endian 16-bit mode. However, Southern Islands GPUs (like the R7 250X) don't support big-endian 16-bit textures. So, 16-bit modes are little-endian. Since AmiCygnix assumes that it has a big-endian mode all the colours are wrong.
AFAIK the Amicygnix author has been informed, so hopefully we'll see an update that addresses this problem.
