젠투 3.8.13 x86_64 업데이트 문제

젠투 3.8.13 x86_64에 대한 전체 시스템 업데이트를 수행하려고 합니다.

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

하지만 다음과 같은 오류가 발생합니다

!!! Problem resolving dependencies for media-video/vlc from @selected
... done!

!!! The ebuild selected to satisfy "media-video/vlc" has unmet requirements.

The above constraints are a subset of the following complete expression:

누구든지 나에게 제안할 수 있나요? 전체 업데이트를 어떻게 수행할 수 있나요?

모두에게 감사드립니다. make.conf에 X 사용 플래그를 추가했을 때 작동했습니다. 하지만 지금은 업데이트에서 몇 가지 메시지를 받고 있습니다.

* 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

나는 다음과 같은 AGP 카드를 가지고 있습니다

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]

이 메시지에 대해 걱정해야 합니까, 아니면 무시해야 합니까?

어떤 제안이라도
