I have a Samsung N-130 I upgraded to 11.10 from 11.04. The flickering screen in 11.10 was worse than 11.04.
My Solution. I installed : Samsung Backlight & Samsung tools The flickering persisted I then added the following to the Grub Menu by editing /boot/grub/grub.cfg noapic nolapic apci=off So that the relevant line is as follows: linux /boot/vmlinuz-3.0.0-12-generic root=UUID=108fc33a-18b8-410f-9991-a6bd4458f1ae ro quiet splash noapic nolapic apci=off vt.handoff=7 The flickering has stopped. And the special function keys now work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/756509 Title: N130 flickering backlight on startup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/756509/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
