I used chvt 1 to switch to virtual console one (I can't use ctrl-alt-F1 due to bug #63795), upon switching back, I get a blank screen followed shortly by X restarting and a new login screen. I see the following in Xorg.0.log.old (WW) Open APM failed (/dev/apm_bios) (No such file or directory) Fatal server error: EnterVT failed for screen 0 Please consult the The X.Org Foundation support at http://wiki.X.Org for help. Please also check the log file at "/var/log/Xorg.0.log" for additional information. *** If unresolved symbols were reported above, they might not *** be the reason for the server aborting. FatalError re-entered, aborting Caught signal 11. Server aborting Reproducible: Always Steps to Reproduce: 1. Start X, open a terminal and execute chvt 1 2. Switch back to vt7 3.

FYI, I'm still seeing this issue with 6.8.0-r3 whenever I switch consoles.
This appears to because the system in question is using the i810 drivers. So this is probably a duplicate bug. I couldn't find one that looked close enough to mark it myself. When I get the chance I will load the system using the i915 drivers and compare.
x11-base/xorg-x11-6.8.2-r1 works fine with no changes to the xorg.conf that was being used with xorg-x11-6.7.0-r3
