As usual no talking in here please. If you find an X11 driver failing with >=x11-base/xorg-server-1.19.0 please file a new bug report nad make that new report block this one.

intel everything works... was the problem of the lack of new drivers https://bpaste.net/show/ac007e02b2c3
I use next universal fix (not tested in most cases): [ "$EBUILD_PHASE" = prepare -a -e "$S"/src/compat-api.h ] && ! grep -Fqs 'SET_ABI_VERSION(23, 0)' "$S"/src/compat-api.h && sed -i -e 's:^\(#define.*\)\(, pointer pReadmask\|, pReadmask\|, pointer read_mask\|, read_mask\)$:#if ABI_VIDEODRV_VERSION >= SET_ABI_VERSION(23, 0)\n\1\n#else\n\1\2\n#endif:' "$S"/src/compat-api.h
new nvidia drivers support xorg-server-1.19 now. I tried to emerge it but it pulls in the live 9999 build of xorg-drivers thus also xorg-server. A bit confused.
You have to unmask xorg-server-1.19 and xorg-drivers-1.19: # Chí-Thanh Christopher Nguyễn <chithanh@gentoo.org> (16 Nov 2016) # Mask until drivers are fixed or adjusted to depend on older versions #599976 =x11-base/xorg-drivers-1.19* =x11-base/xorg-server-1.19* Stick that in package_unmask and fix the rdepend in nvidia-drivers-375.20 and all will install and work. I am running it now with no issues.
x11-drivers/nvidia-drivers-375.20 still depends on <x11-base/xorg-server-1.18.99 " (x11-base/xorg-server-1.18.4:0/1.18.4::gentoo, ebuild scheduled for merge) pulled in by <x11-base/xorg-server-1.18.99:= required by (x11-drivers/nvidia-drivers-375.20:0/375::gentoo, ebuild scheduled for merge) ^ ^^^^^^^ ^ "
All drivers should be fixed and xorg-server-1.19 is now unmasked: commit d25dfef07e1335fd04cef080bbe3d6ff528d5b7e Author: Matt Turner <mattst88@gentoo.org> Date: Wed Jan 25 09:24:52 2017 -0800 profiles: Unmask x11-base/xorg-server-1.19.
