[Desktop-packages] [Bug 1313275] Re: relogin fails with black screen, Xorg high load
After weeks of being unable to track down the problem it seems to have disappeared for me. Since it was not reproducable and the load was not connected to any task I can only guess if it's been fixed by a regular update or if it's related to my deinstallation of the "virtualbox" package, although virtualbox was never run while the problem occured. Unscientific Conclusion: If you have weird load problems as of 14.04 and the virtualbox package installed: Try if deinstalling helps. I'm sorry I can't add anything more substantial to this. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1313275 Title: relogin fails with black screen, Xorg high load Status in “xorg” package in Ubuntu: Confirmed Bug description: Using a desktop with two users, it often hangs switching from one to another.

[Desktop-packages] [Bug 1313275] Re: relogin fails with black screen, Xorg high load
I'm quite sure this problem affects me as well. Unfortunately my linux knowledge seems insufficient to track this problem down properly so I can only add some observations since upgrading my workstation to 14.04LTS : * arbitrarily the load jumps from normal (between 0 and 3 during standard desktop workstation operations) to exactly 15 but(!) without really slowing the system down except for delays when switching users or trying to log in or out. This often (but not exclusively) happens after resuming from a lock screen. * iostats yields NO write/read load during high load * top yiels NO task excessively or exclusively consuming any CPU * there are no network shares mounted * a reboot solves this problem for several hours again. * shutdown hangs on Askingh all remaining processes to terminate - No error is shown but I have to hard-reset the pc. (as far as I can see after unmounting all filesystems - I had no fs problems regarding this issue so far) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1313275 Title: relogin fails with black screen, Xorg high load Status in “xorg” package in Ubuntu: Confirmed Bug description: Using a desktop with two users, it often hangs switching from one to another.
