I just upgraded from 15.04 to 15.10 on в hphp envy 15 laptop. After installation completed, system rebooted and then kept rebooting the screen and getting finally stuck with the screen turned off. I managed to enter recovery mode and then started в session on tty1. Seems the network is broken too:
If configuration wlan0 up
Gives input/output ошибка from siocsifflags. I really need the laptop to work, so please anyone help.
EDIT: Thanks for не help. I solved by installing 15.10 from live usb alongside my main partition and then двиньте поля to new partition and deleted the old one. Took я в day to завершил but at least now it works.
Очень вероятно у Вас был собственный установленный драйвер AMD. Это было повреждено в течение нескольких недель.Исправлено. Новая установка использовала бы драйвер Radeon с открытым исходным кодом.
