The behavior of VT switching points toward a low-level bug, rather than an application bug (cf. #437607):
0. After first login: X consumes 100% CPU 1. Alt+SysRQ+R (release KB, the VT switching seems to be disabled in default configuration?) 2. Alt+F1 (switch to VT1) 3. Something (Xorg?) causes the VT to switch immediately back to VT7 3b. The "Switch user" functionality in Gnome doesn't work either: VT switches always back to VT7 4. Log out from X, log then back in 5. X cpu consumption low 6. Alt+F1 7. Now the VT does not switch immediately back 7b. Also "Switch user" functionality works again. It could be useful if the past/future me-tooers verified if they see this same behavior vs. VT switching. There may be multiple causes for 100% cpu consumption, but to me the above seems too much of a coincidence to be accidental. -- [karmic] Xorg 100% CPU utilization -- only after first login https://bugs.launchpad.net/bugs/439138 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
