I found this report while I was searching for a solution for a quite similar problem. I think it’s the same.
For playing games I start an xserver from tty1 with (simplified) “xinit /usr/bin/xterm "$@" -- :1”. If I try to close the session by just typing “exit” in the xterm window of the second xserver the screen blanks immediately and even the LCD-backlight turns off. The only way out is Magic SysReq (R-E-I-S-U-B). The screen comes back to life after killing processes (I-Key) showing the white cursor. I attached the related lines of syslog. The lines with “XINIT-TEST” are generated by myself with the logger command. ** Attachment added: "syslog.txt" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1004983/+attachment/3194950/+files/syslog.txt -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1004983 Title: X.org segfaults when exiting window manager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1004983/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
