How to fix Netbook restart issue with Linux (Ubuntu)
Posted: Sun Jan 15, 2012 3:10 am
I installed Ubuntu 11.10 on my newly bought Acer Aspire One D257 netbook. Though it came with Windows 7 Starter I couldn't live without Linux
However there was a strange restart issue. Netbook never restarted and ended up in a black screen unlike on the Windows starter installation. However Power Off worked perfectly. After making several attems I was able to fix it and though it would be helpful to share this information with you.
The reason for these issues could be a BIOS issue or the hardware setup of the system. For example some netbooks with Atom processor doesn't come with a keyboard controller in which case Linux kernel can't figure out the way to tackle that situation. However the best thing about Linux is, there is always a solution if you can sit in-front of for many hours
Acer Aspire One D257 netbook - efi fixed the issue
Acer Aspire One Happy 2 netbook - acpi fixed the issue
Dell latitude E6420 - pci fixed the issue
Please add what worked for you to this list.
