Comment 15 for bug 1606103

Ok, thanks for the info re dpkg-buildpackage.

xf86DefModeSet.c is created by hw/xfree86/common/modeline2c.awk. If you run dpkg-buildpackage, you'll find it two places:

$ find -name xf86DefModeSet.c
./build-main/hw/xfree86/common/xf86DefModeSet.c
./build-udeb/hw/xfree86/common/xf86DefModeSet.c

xf86DefModeSet.c is built using the files hw/xfree86/common/vesamodes and hw/xfree86/common/extramodes. extramodes is modified in the build process by debian/patches/001_fedora_extramodes.patch, so editing extramodes directly means the patch and therefore build fails. The packages do build if I add my missing modes to vesamodes and because all the modes are combined into the one xf86DefModeSet.c, I assume it'll work for testing purposes.

dpkg-buildpackage builds a whole bunch of debs:

xserver-common_1.18.4-1ubuntu6_all.deb xserver-xorg-core-udeb_1.18.4-1ubuntu6_amd64.udeb
xserver-xephyr_1.18.4-1ubuntu6_amd64.deb xserver-xorg-dev_1.18.4-1ubuntu6_amd64.deb
xserver-xorg-core_1.18.4-1ubuntu6_amd64.deb xserver-xorg-legacy_1.18.4-1ubuntu6_amd64.deb
xserver-xorg-core-dbg_1.18.4-1ubuntu6_amd64.deb xserver-xorg-xmir_1.18.4-1ubuntu6_all.deb

It looks like installing xserver-common and xserver-xorg-core should be sufficient to test my changes, is that correct or do I need the udeb or any of the other packages?
