Public bug reported:
The default boot process on the very recent acer extensa 5635z does not display
anything after grub. The backlight is on but everything stays black.
Luckily an external display connencted before boot displays everything just
fine. The internal display is again always black. So I did an ubuntu-bug linux
just after boot up with the external monitor connected. Screenshot1.png shows
that the monitors are in mirror mode at 1024x768.
At a previous boot I played around with the display settings a bit more (via
the GUI). I could set the external monitor to its native resolution. That
displayed fine. I could also set the internal monitor to its 1366x768 native
resolution, but it stayed black. A screenshot captured all the contents of the
two screens just fine. See Screenshot2.png.
Please let me know what further information is needed to fix this bug.
