I installed Ubuntu 12.04 alongside Windows 7 and sometimes, after selecting Ubuntu from GRUB menu, a black screen with a blinking pointer appears for a while. Then the screen goes black and nothing happens. I tried recovery mode and after some processing, I saw a repeating message that goes something like this:
udevd: timeout: killing '/sbin/modprobe...
After some restarts, I managed to reach the boot screen. When booting was complete, I encountered an internal error report saying:
ExecutablePath /usr/share/apport/apport-gpu-error-intel.py Package xserver-xorg-video-intel (not installed) ProblemType Crash Title [sandybridge-m-gt2+] GPU lockup IPEHR: 0x25102000.... ApportVersion 2.0.1-0ubuntu17.1 Architecture amd64
Not sure if the last block is related to the crash, but since it involves a GPU lockup, I figured it would. Any suggestions on what the best action to avoid the black screen boots would be?
