Further evidence - If the machine suspends itself after 20 mins I resume by pressing power button. This presents a login that looks perfectly normal, no screen corruption, no lock up.
However, if I force a logout the graphics screen goes and the screen hangs with text showing /dev/sda setting advanced Power Management level to 0xfe (254) All I can do is to switch to tty1 and restart kdm; then I get a normal login screen. In summary: The corrupt login screen and graphics hang only occurs on initial login when that tty is on screen. Other logins seem to behave normally. A forced logout fails to get back to the login screen. -- corrupt login screen and lockup during login when using desktop effects https://bugs.launchpad.net/bugs/355508 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
