Luckily the other way around does work, so for the q8_a13_tablet_defconfig I'm using the modeline from the fex file from tablet b. I hope we can do something similar with q8 a23 and a33 800x480 tablets. I've been buying q8 tablets with cracked screens (people seem to drop them quite a lot) for cheap from a local 2nd hand website, so now I've 5 ever so slightly different models, I still need to make a generic q8 config for those, and see if I can find a modeline which works on all of them. That modeline should probably be a good one to use for the a33 defconfig too. > I'll find some time to give yours a test. Thanks! Regards, Hans
