I repeated test 3 with boot options changed to remove "quiet" and "splash" and add "drm.debug=0x02". The result was that kernel messages ran across the laptop screen at some low resolution until reaching the error "ureadahead main process (381) failed with status 5" then the screen went blank. The system didn't continue on any further. I didn't see the message about plymouthd.
I repeated test 1 with the same boot options as above. The result was that kernel messages ran across the laptop screen at some low resolution until reaching the error "ureadahead main process (381) failed with status 5", then the screen switched to a higher resolution and a few more kernel messages ran across the screen. Then X started. After I plugged in the screen and ran xrandr -q the screen went blank and the ssh session stopped working shortly after. There wasn't enough time to get any debugging info. It seems that the splash option makes no difference. -- [arrandale] X freezes after plugging in external monitor and selecting System>Preferences>Monitors https://bugs.launchpad.net/bugs/599626 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
