When did this problem appear? Did you upgrade something as this time?
Could the problem be related to switching to a VT console and then back
to X? Or related to some applications?
Could you send the output of
/usr/share/bug/xserver-xorg-core/script 3>&1
so that we see your config and log (reportbug should have included this
output automatically in your first report).
