Red Hat Bugzilla – Bug 967545
unable to log in, 100% CPU load
Last modified: 2014-09-30 19:41:25 EDT
I installed RHEL7 0522-Workstatation compose today, after trying to log in as a regular user through GDM I only see gray background a cursor. The virt host this is running in shows 100% CPU load for the virt machine with the RHEL7.
switching into tty2 and checking 'top' output, there is gnome-shell taking 95% of the CPU.
Upgrading from F17 to F19 using FedUp. Has similar behavior. With one monitor it is OK. Second monitor causes gnome-shell to use CPU at about 150% (dual core machine). Seems to last indefinitely. Removing external monitor causes behavior to disappear. Seems to occur in both Gnome and Gnome classic. Version 3.8.4. Did not notice this happening in F17.
With one monitor gnome-shell uses ~20% CPU. Switch to LXDE resolves the issue. Two monitors runs as expected. Process "X" runs at about ~2% CPU, ~95% idle. Integrated Intel 945GM.
Whoops. Enabled KDM before switching to LXDE. Before this LXDE may have had similar problem.
yum install kdm;systemctl enable kdm.service;systemctl disable gdm.service;

has this been reproduced with rhel7 beta or newer ?
No, haven't seen it since, only that one time. Completely fine to close this.
