Gentoo 3.8.13 x86_64の完全なシステムアップデートを実行しようとしています。

emerge --update --deep --with-bdeps=y --newuse world

しかし、次のエラーが発生します

誰でも私に提案できますか？フルアップデートをどのように実行できますか？

みんなに感謝します。 make.confにX有効フラグを追加したときに動作しました。しかし、今はアップデートからいくつかのメッセージを受け取っています。

* Messages for package x11-drivers/ati-drivers-13.4:

*   CONFIG_DRM must be disabled or compiled as a module and not loaded for direct
*   rendering to work.
* Please check to make sure these options are set correctly.
* Failure to do so may cause unexpected problems.
* 
* Please note that this driver only supports graphic cards based on
* Evergreen chipset and newer.
* This includes the AMD Radeon HD 5400+ series at this moment.
* 
* If your card is older then use x11-drivers/xf86-video-ati
* For migration informations please refer to:
* http://www.gentoo.org/proj/en/desktop/x/x11/ati-migration-guide.xml
* To switch to AMD OpenGL, run "eselect opengl set ati"
* To change your xorg.conf you can use the bundled "aticonfig"
* 
* If you experience unexplained segmentation faults and kernel crashes
* with this driver and multi-threaded applications such as wine,
* set UseFastTLS in xorg.conf to either 0 or 1, but not 2.
* 
* Fully rebooting the system after an ati-drivers update is recommended
* Stopping Xorg, reloading fglrx kernel module and restart Xorg
* might not work
* 
* Some cards need acpid running to handle events
* Please add it to boot runlevel with rc-update add acpid boot

私は次のようなAGPカードを持っています

VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Park [Mobility Radeon HD 5430/5450/5470]
Audio device: Advanced Micro Devices [AMD] nee ATI Cedar HDMI Audio [Radeon HD 5400/6300 Series]

このメッセージについて心配する必要がありますか、それとも無視する必要がありますか？

どんな提案でも
