Thank you for your message. The only possible issues in the dmesg logs are these lines:
[ 19.426027] nouveau [ DRM] 0: core 425MHz shader 425MHz fanspeed 100% [ 20.449899] init: avahi-cups-reload main process (994) terminated with status 1 I am not sure why the avahi-cups service (printer's network search/sharing) has restarted but it should not be related to this particular issue as it occurs so early during the boot. Can you tell me if you've noticed any issues with your graphic card's fan? Could you also please attach the Xorg.log and Xorg.0.log files from the /var/log folder to this report? Thanks in advance. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1176062 Title: System crashes when starting Firefox and/or Thunderbird Status in “firefox” package in Ubuntu: Incomplete Status in “thunderbird” package in Ubuntu: New Bug description: When starting up either Firefox or Thunderbird,the system freezes. First the cursor usually freezes and no input is possible, but the desktop display remains, sometimes for a few seconds. Then a pattern of horizontal bars appears on the screen. The bars are about two or three inches wide and about an eighth of an inch high, in various shades of color or black and white. Each thin horizontal bar looks like it is a sliver copied from the display picture that existed on the screen before the crash. System almost always crashes when I click on an e-mail link in Thunderbird, as soon as the system attempts to start up the Firefox browser. System frequently crashes if I attempt to start up either Firefox or Thunderbird after I have previously run the other application. So, if I run Thunderbird and close it, then try to run Firefox, a crash occurs. Or if I run Firefox and close it, then try to run Thunderbird, I get a crash. System occasionally crashes the first time I try to run either Firefox or Thunderbird, even when I have never opened either application previously during the session. Basically, I can only use either Firefox or Thunderbird once, or sometimes twice, per session, before the system freezes and requires a cold boot. System crashed after leaving it for a few hours. The screen saver blanked out the screen by that time, I move the cursor, the application I had been using appeared briefly (it was a Sudoko game I had been playing a few hours earlier), then the lines appeared in its place and the system froze. Pressing Alt+SysRq+1 followed by Alt+SysRq+t does nothing. It is a total system freeze and requires a cold boot. Problem began after installing upgrade to Ubuntu 13.04 (raring). My system is: Ubuntu 13.04 (raring) Gnome 3.6.3 Kernel 3.8.0-19 generic GCC Version 1.13.3 CPU Athentic AMD Model AMD Athlon 7850 Dual-Core Graphics Card: NVIDIA C61 (GeForce 7025 / nForce 630a) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1176062/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
