.tgzx from rv200 host gx27b of Xorg.0.log and dmesg from Fedora, Mageia and openSUSE installations
1-login on a vtty
3-close DE session normally
1-black vtty screen shows no visible text
1-visible shell prompt following visible server exit messages
1-"Black" is not always fully opaque. Sometimes text can be faintly seen. Leaving via Alt-Fn the active vtty and returning produces expected foreground and background.
2-Reproducible on multiple hosts with Radeon rv200 AGP and Nvidia nv11 AGP in Tumbleweed (kernel 4.0.3, server 1.17.1), Mageia 5 (kernel 3.19.7&8, server 1.16.4) and Fedora (22: kernel 4.0.2 server 1.17.1, and Rawhide: kernel 4.1.0.rc231, server 1.17.1).

On the following installation, recovery from black only screen on exit from X session is only possible by rebooting:

On rv200 host m7ncd with kernel 4.1.4, server 1.17.2 and ati driver 7.5.0-1.5 on openSUSE Tumbleweed this seems to have been fixed....
This is still broken on rv200 host m7ncd in Fedora 23 with kernel 4.2.rc6git0.2, server 1.17.2, ati driver 7.6.0...20150709.
This is still broken on rv200 host gx27b in Fedora 24 with kernel 4.2.rc8git0.1, server 1.17.99, ati driver 7.6.0...20150729....
This continues on rv200 host gx27b in Fedora 26 with kernel 4.11.5-300, server 1.19.3, ati driver 7.9.0-1, linux-firmware 20170605.
This has returned on rv200 host gx27b in openSUSE Tumbleweed with kernel 4.11.5, server 1.19.3, ati driver 7.9.0-2.2, linux-firmware 20170530.
This is happening in both Fedora 27 and Debian 9.2 on same host gx27b.
