Yesterday I installed installed ubuntu 12.04 on my Acer aspire one D270-1838. Everything worked ok, except I couldn't adjust brightness, I fixed it changing:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
The problem is when I closed the lid it suspended properly but trying to start it again it showed a crashed screen. I have read people with a similar problem but they report screen completely black, mine isn't. I wanted to upload an image of the screen but I don't have the reputation....
Something I can do to suspend my netboot and that works fine is type:
sudo pm-suspend --quirk-dpms-on
and it suspends correctly but without authentication, that's not a problem for me but it is tedious. Also, I can enter a virtual terminal with ALT+CTRL+F1 which works fine and kill X, this fixes the screen crash but also terminates my session. however there are sometimes that after the first try if I try to close the lid and open it up again, the screen stays on but black and I cant enter the virtual terminal.
I'm not tech saavy, but I hope you can direct me to a way of fixing this problem.
