<html> <head> <meta content="text/html; charset=ISO-8859-1" http-equiv="Content-Type"> </head> <body bgcolor="#FFFFFF" text="#000000"> I got a similar problem some times ago... I had 2 possibles hints : 1- no more space on disk (old machine, small (very small) disk This has been corrected by keeping only 2 logs files instead of 5 or 7 by default... By this way I no more had "disk full" messages at start-up and I was able to check the logs 2- The screensaver was mis-configured. ( I tried to have a diaporama, but it did not work well) Setting it to "blank screen" only was the right solution : No more lock up. When the screen is "locked-up" , do you have a big disk activity? I had the disk light continuously "ON" (hence my check of disk space) When it is locked up, can you get a tty login with <ctrl><alt><Fn>? Be patient.... If you can't get a tty login, the desktop manager is no more running.... If yo can get it, a "top" will show you what are the most cpu consuming task. Good luck <div class="moz-cite-prefix">Le 11/06/2014 05:49, Rob Ward a écrit : </div> <blockquote cite="mid:5397D1C8.5040807@bigpond.com" type="cite"> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> Hi Folks, My swap from XP to XUbuntu is going well, but every couple of days I get a lock-up from which I have no way out but to press the reset and reboot. I am wondering if there is a way I can gather some evidence as to what might be going on, so I can either correct it myself, or seek help from you folk with more information than "It crashed! Help!". Sometimes it locks up on the screen saver (3-D Ant (mentioned in many older www posts)) and other times just in the Desktop, but usually after some time of operator absence. <div class="moz-signature"> Ubuntu 14.04 LTS Cheers, Rob Ward Lake Tyers Beach, 3909 <a moz-do-not-send="true" href="http://www.laketyersbeach.net.au">Lake Tyers Beach Website</a> <a moz-do-not-send="true" href="http://www.laketyersbeach.net.au/XP2XU.html">XP to XUbuntu - The journey, join me!</a> </div> <fieldset class="mimeAttachmentHeader"></fieldset> </blockquote> </body> </html>
