|
|
So here's a fun one for you. When I boot about 1/2 to 1/3 of the time my keyboard does not work. Here are the conditions:
- Grub allows the keyboard to work
- Once load starts, I can at times hit keys and see the characters echo back, other times they do not.
- If the characters do not echo back, then my keyboard, mouse, and even power buttons do not work in either X or command line.
Interestingly enough, this isn't a "Gentoo" problem, as every distro I've tried does the same thing. Obviously doing a hard shutdown (press and hold the power button) 2-3 times until I get the keyboard working isn't a solution. So here's what I need.
- What can I do to ensure my keyboard is detected consistently.
- If that can't be done, what I can do to provide good debug information about the problem.
Thanks _________________ [Insert favorite Ghandi quote here]

theMerge,
USB or PS/2 Keyboard ?
Post your lspci output and your kernel .config file.
The .config file will need to go to a pastebin as its too big to fit in a post.
Oh - your dmesg may be useful too - again that needs to be on a pastebin. _________________ Regards,

Looks like a BIOS/hardware problem TBH.
Output of dmesg (or relevant part of /var/log/messages) from the case when keyboard is not detected would be a good starting point. |

Try adding this to your grub.conf:
i8042.nomux=1 i8042.reset
Example: Code: | kernel /boot/kernel-3.2.1-gentoo root=/dev/sda3 i8042.nomux=1 i8042.reset |
You can hit the "e" key at grub boot and add it manually to test it. |

Ion Silverbolt, I could kiss you. I no longer need to boot into windows all the time. I've done several consecutive boots and it appears things are good. I'll marked solved. _________________ [Insert favorite Ghandi quote here] |
