Public bug reported:
After update from Ubuntu 17.04 to 17.10 on my Acer Aspire One netbook
(model ZG5) I have a problem with framebuffer corrupting the notebook
internal display after modeset.
During system boot, when correct console screen resoltion is to be set,
roughly 80% of the screen on the left side gets corrupted (looks like
framebuffer is trying to put 1024px line in 800px, so it overflows onto
the next line, causing the screen to be unreadable). This effect
persists after gdm boots up, so only right 20% of the screen is visible
and the rest is still garbled.
I have so far found to workarounds for the issue:
- add nomodeset kernel option in grub at boot time (or add it as
GRUB_CMDLINE_LINUX_DEFAULT)
- use 4.10 kernel from Ubuntu 17.04 that I still have installed
There are reports on stackexchange of the same problem happening for
other netbooks like Samsung NC10.
