I am having the same problem on Acer Extensa EX5235-901G16MN with chipset Intel GL40, graphics card Intel GMA 4500M.
With the i915.modeset=0 the system boots but I am unable to play any DVD or video via Totem, VLC or other media player as GUI crashes back to login page. Note Flash videos (YouTube) are ok. -- i915: black screen on boot https://bugs.launchpad.net/bugs/431812 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
