For the OpenGL ES support in X11 on sunxi hardware, I have a project page here, which happens to list some contact information and describes the process of reporting issues: https://github.com/ssvb/xf86-video-fbturbo
Right now OpenGL ES is working fine for me, i have a couple of ideas for trying to cause the problem again. Today i won't be able, but in the next days I'll do some experiments to see If the problem can be caused/fixed at will. at that point it can be documented (or fixed if there is anything to fix and wasn't just wrong procedure at some point)
Thanks. I'm definitely interested to know what was causing. Just to be sure that we can avoid it in the future. Also please report any other problems or oddities if you encounter them (preferably to the bugtracker, and not to this mailing list). Using irc is also fine for quick questions, but my presence may be limited at the usual office hours or in the middle night (European time).
It may seem that I have some prejudice against Mer, but have a look at this relatively recent bugreport for example: https://github.com/ssvb/xf86-video-fbturbo/issues/25 Nothing can be ruled out and it is difficult to make any assumptions about what could be possibly wrong in the user's system.
There is one more thing that may be relevant for you. The old r3p0 version of the mali blob can't fully utilize both pixel processors of the Mali400 MP2. So the performance is not optimal on Allwinner A20. It is possible to upgrade to a newer version r3p2-01rel2 of the blob to get better performance, but I was not very sure about it without a good justification (like somebody having a real use for OpenGL ES and able/willing to report bugs): http://thread.gmane.org/gmane.comp.hardware.netbook.arm.sunxi/4676 Also blobs are a temporary placeholder solution until we get free open source drivers. Investing extra efforts into getting blobs running may be counter productive at this moment.
