Fedora 16 على Sony VAIO VPCEA31E

يوم أمس توصلت بحاسوب محمول من فئة Sony VAIO VPCEA31E لأثبت عليه فيدورا لينكس 16 Fedora. توقعت أن أواجه صعوبات في إعداد قطعة عتاد أو أكثر خصوصا و أنه بمواصفات حديثة نوعا ما:
  • المعالج من نوع Intel Core i3 M370. بطاقة العرض من نوع ATI Mobility HD 5470.
  • بطاقة الصوت من نوع Realtek HD بمخرج صوت من نوع ATI HDMI.
  • بطاقة اللاسلكي من نوع Atheros AR9285 و أخرى سلكية من نوع Marvell Yukon 88E8059.
رغم 4GB من الذاكرة و معالج بنواتين كل واحدة بخيطي تشغيل بسرعة 2.4Ghz و نظام ويندوز 7 بمعمارية 64بت إلا أن النظام بطيء الإستجاب و يزحف.

أقلعت بـ Fedora 16 بعد أن نسختها على فلاشة. ثوان مرت لألاحظ أن دقة عرض الشاشة تم تحديدها بشكل صحيح من طرف النواة الشيء الذي يعني أن خاصية KMS مدعومة بشكل جيد. بضع ثوان أخرى لتظهر واجهة Gnome 3.2 بقوقعتها GnomeShell و بكل المؤثرات الرسومية و هذا يعني بدوره أن التسريع الثلاثي الأبعاد بواسطة العتاد يعمل بشكل جيد. ألقيت نظرة سريعة على التشيك اللاسلكي لأجده تعرف على نقطة الوصل و ينتظر فقط إدخال كلمة السر لإن التشبيك مشفر بـ WPA.

شغلت المثبت الذي ثبت فيدورا 16 في حدود 4 دقائق. بعدها أعدت تشغيل الجهاز ليقلع بالنظام الجديد لأجد كل قطع العتاد على هذا الجهاز تعمل بشكل جيد!. قمت بتحديث النظام
sudo yum update


ثم تذكرت أن الجهاز يتوفر على 4GB من الذاكرة التي لا يتم إستغلال جزء من مساحتها (600MB تقريبا) بحكم أن النظام المثبت بمعمارية 32بت و نواة لينكس الإفتراضية على فيدورا لا تفعل خاصية PAE بشكل افتراضي لتبقى متوافقة حتى من المعالجات القديمة أو تلك التي لا تدعم ملحق العنونة الفعلية PAE. يكفي تثبيت نواة بـ PAE:
sudo yum install kernel-PAE kernel-PAE-devel kernel-headers


ثم بعد إستخدام الجهاز لبضعة دقائق تحت حمل منخفض لاحظت أن صوت المروحة و سرعتها لاتتراجع و هذا غالبا مؤشر على مشكلة في إدارة الطاقة لبطاقة العرض خصوصا و أن التعريف مثبت و يعمل بشكل جيد من حيث الأداء. بحث سريع أوضح أن تعريف ATI/AMD المفتوح المصدر يستخدم مجموعة من الأنماط لتحديد الأداء و بالتالي إستهلاك الطاقة و أن هناك بعض الحواسب المحمولة التي لا تتصرف جيدا عندما تترك بالإعداد القياسي كما هو حال هذا الجهاز على ما يبدوا.
لتحديد الإستهلاك المنخفض لبطاقة العرض يكفي تنفيذ ما يلي:

echo low | sudo tee /sys/class/drm/card0/device/power_profile

و فعلا انخفظ صوت المروحة بشكل آني. ثم ليصمد ذلك الإعداد على فيدورا 16 بعد إعادة تشغيل الجهاز يكفي تنفيذ ما يلي :
echo '#!/bin/bash' | sudo tee /etc/rc.d/rc.local
echo 'echo low > /sys/class/drm/card0/device/power_profile' | sudo tee -a /etc/rc.d/rc.local
echo 'exit 0' | sudo tee -a /etc/rc.d/rc.local
sudo chmox +x /etc/rc.d/rc.local

جيد، لم يتبقى سوى تفعيل خاصية النقر في مساحة التحديد للفأرة بدل الضعط على الزر المخصص للفأرة. من على إعدادات الفأرة على مركز إعدادات جينوم فعلت "enable mouse clicks with touchpad"

ولتفعيل نفس الخاصية عند شاشة تسجيل الدخول يكفي إضافة السطر
Option "TapButton1" "1"
إلى الملف /usr/share/X11/xorg.conf.d/50-synaptics.conf

sudo gedit  /usr/share/X11/xorg.conf.d/50-synaptics.conf

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "TapButton1" "1"
EndSection

و هذا كل شيء.

بعدها قمت بتثبيت بعض الحزم الإضافية:
sudo rpm -ivh http://rpm.livna.org/livna-release.rpm
sudo yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
sudo yum localinstall --nogpgcheck http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
sudo yum check-update

sudo yum install gstreamer-plugins-{base,good,bad-free,bad-nonfree,ugly,base-tools} gstreamer-tools gstreamer-ffmpeg libdvdcss dvd+rw-tool libdvdnav libdvdread libvpx ffmpeg gnash-plugin gnome-tweak-tool p7zip p7zip-plugins


كل ما قد يحتاجه المستخدم بعد تثبيت فيدورا 16 موجود في موضوع خاص على مجتمع لينكس العربي. كما يوجد موضوع خاص لحل مشاكل المستخدمين هناك.





في النهاية، حتى تبقى تفاصيل عتاد هذا الحاسوب كمرجع سأضعها أسفله :
