nvidia driver 314.X for Geforce 9800 GT and kernel module

I had some problem with new nvidia-driver (314.X)  and my card Geforce 9800 GT.
So, to avoid problem again, I change the driver.Now, I use the open source driver for nvidia : nouveau
It works and it's easy to configure : http://wiki.gentoo.org/wiki/Nouveau

Click on Input Devices.Then choose keyboard and go on the Layouts tabs.
Click on the configure layouts checkbox.
Then you have to click Apply.
If you restart your KDE console, the mode should be change.

eth0 does not exist ( renamed in enp2s0 )

I upgraded my gentoo and I had a problem with internet connection.
The following command told me that eth0 didn't exist :

/etc/init.d/net.eth0 restart

I checked if my network card exists by making :

dmsg -v | less

It exists because I had a line similary to:

02:00:00 Ethernet controller : .....

So, I checked all my network interface  :

ls /sys/class/net 

In the result list, there was no eth0 interface. However, there was enp2s0 interface.
I solved my problem by creating a symbolic link ( you could see this good wiki : https://wiki.archlinux.org/index.php/Dhcpcd#Dynamic_IP_address )

ln -s /dev/null /etc/udev/rules.d/80-net-name-slot.rules

emerge and less

When you use emerge, you want cetainly use less.
But, if you want it work, you have to do the following :

emerge -p system 2>&1 | less

Mysql install on Gentoo

I've tried to install Mysql with emerge but without success. That's why, I install it manually by following the install file in the binary distribution :

• shell> groupadd mysql

• shell> useradd -r -g mysql mysql

• shell> cd /usr/local

• shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz

• shell> ln -s full-path-to-mysql-VERSION-OS mysql

• shell> cd mysql

• shell> chown -R mysql .

• shell> chgrp -R mysql .

• shell> scripts/mysql_install_db --user=mysql

I have the following error :

Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

To solve this issue , I install libaio with emerge dev-libs/libaio

• shell> chown -R root .

• shell> chown -R mysql data

• shell> cp support-files/my-medium.cnf /etc/my.cnf

• shell> bin/mysqld_safe --user=mysql &

In the file monfichier.err which is located in  /usr/local/mysql/data/ I have the following error : Can't open and lock privilege tables: Table 'mysql.user' doesn't exist

I solve the problem with mysql_install_db --user=mysql --ldata=/usr/local/mysql/data/


Note :
I have the same error with :
GRANT ALL ON tbl.* TO 'user'@'localhost' IDENTIFIED BY 'tbl';
==> Error Mysql.User doesn't exist

In fact, I have an old version of Mysql on my computer. So, I unstall it and I type the following :

./scripts/mysql_install_db --user=mysql --ldata=/usr/local/mysql/data/

CONFIG_DEVTMPFS: is not set when it should be

Problem

emerge  sys-fs/udev

* Messages for package sys-fs/udev-200:

 *   CONFIG_DEVTMPFS:    is not set when it should be.
 * Please check to make sure these options are set correctly.
 * Failure to do so may cause unexpected problems.

Solution

 You have to check the following  option in your kernel config :

 Device Drivers-> Generic Driver 
* Maintain a devtmpfs filesystem to mount at /dev.  

 For getting the devfs automatically mounted at boot time it makes sense to also enable the option  
* Automount devtmpfs at /dev
