freeze when X tries to start #2

After the kernel and everything else was compiled (using config tweaks from #1), when I rebooted the Pi, it froze when X attempted to start.

Yeah, it did that for me too. I don't remember the exact error. I built my Mesa differently - got the source from "apt-get source mesa" and added vc4 to the --with-gallium-drivers in debian/rules. X started, the Xorg log showed vc4 for DRI2, but the screen went blank and an error showed up in dmesg.

I'm going to repeat with Pi 2 and Debian Sid (instead of Raspbian) and see if I can get that working.

I was able to fix it by making a symlink from /usr/bin/X to /usr/local/bin/X. When I ran X, it started fine, but when I tried startx it gave me a corrupted login screen before it segfaulted. I have figured out that this is also the case for when LightDM is running.

Yes, so far I've also only seen the corrupted screen, and it does sometimes lock up on the Pi 2 when using upstream-based kernels. This is all very much in flux still, but I expect it to work very soon.

With regards to building: this is specifically made for being run on Raspbian.
