** Description changed: - I am not sure at all what package this bug is; I report it against Unity - because I get to see the purple screen... + Since the incomplete/broken "fix" for #1431753 was released, and hence + NVidia drivers version 340 were installed AND enabled on my machine + (where previously I had 331 installed and disabled) this has started + happening: - Steps to reproduce: - - turn on the laptop while not connected to AC power, but with more than enough battery charge (tested with battery completely charged) + About 50-75% of the times (very rough estimation), when I boot, the boot + gets stuck at the purple screen with the "Ubuntu" word with four red + dots below. - Expected result: - should boot fine + Systematically, when this happens, that screen is preceded by a black screen with a lot of errors, of which I attach a picture (yes, I know, it's unreadable, but it's all I can do). + If anybody tells me in which log files those errors can be found, I will be happy to attach them. - Observed result: - When the purple Ubuntu loading screen appears and the four dots below the word "Ubuntu" are all filled in red, the system gets stuck at that screen for fucking ever. - No matter how many times I retry, it will always remain stuck there. - If I connect the charger and reboot, then it works fine. + Normally, that is, when the issue does not happen and the boot is + succesful, the black screen preceding the purple screen would only + contain one line with an unrelated error that has to do with USB. - This REGRESSION has appeared after some recent automatic updates. This - didn't use to happen before. I had booted with battery power thousands - of time, though it's not something that I do very often so i can't tell - exactly when the regression appeared. - - - Before the purple screen appears, for a fraction of a second I've been able to see a black screen full of messages, probably error messages, while normally (when boot works fine) there would only be one usb-related error message. - - Please let me know from which log I can retrieve those error messages so - that I can post them here. - - Don't tell me to update the bios, because this used to work on the very - same machine, so the issue is obviously in Ubuntu.
