This is either at booting, when the X-server starts for the first time, or when I switch to the console and back to X manually using Ctrl-Alt-F1 followed by Alt-F7. For one switch I get typically three such warnings with call traces, and there is a clear delay of about a second before X is responsive again after the switch. Any keys presseed during this time are swallowed. Then there is a short flicker of the whole screen just before X is again responsive to kbd and mouse input.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
