I have downgrade my xorg drivers, so I can hibernate and stand by my ubuntu smoothly.
However, in some case, there's a problem.
My ubuntu get hang. When I tried to switch to console mode (Ctrl+Alt+F1), then I cannot login.
The system always reply with an error whenever I tried to press a key.
When I press Ctrl+Alt+Del to perform a softreset, here what's it said:
[80141.320122] end_request: I/O error, dev sda, sector 193687181 init: control-alt-delete main process (5660) terminated with status 2.
This error is not even recorded in syslog. I guess this should be a problem with my hard disk since it said something about a bad sector.
Exactly, what kind of error is this?
