I should add a couple more things. I initially assumed that it might have something to do with the processor running slower while in battery power and something not being detected or run in time, so the default going to text mode. However, the behavior was unchanged when I changed BIOS settings to set the computer to run at full speed even on battery power. I don't know how soon the OS takes over control of power-saving, but I thought I'd add that bit of information.
Also, I can't directly hit ALT-F7 or CTRL-ALT-F7 to get to the graphical login. I do have to switch away to another screen first. -- Computer boots to text when on battery power https://bugs.launchpad.net/bugs/570233 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
