He pasado unas cuantas horas trasteando con el kernel en Ubuntu, queria activar un par de cosas:<\/p>\n
Lo primero ha sido descargarse las fuentes del kernel, queria utilizar el \u00faltimo disponible y aplicar los parches de Ubuntu para que me funcione lo m\u00e1ximo posible con la distribuci\u00f3n (mantener la modularidad y tal para la autodetecci\u00f3n de hardware). He a\u00f1adido al fichero \/etc\/apt\/sources.list:
\n<\/p>\n
:\/\/archive.ubuntu.com\/ubuntu hoary main restricted universe multiverse\r\ndeb-src http:\/\/archive.ubuntu.com\/ubuntu hoary main restricted universe multiverse\r\n<\/pre>\nHe actualizado el listado de aplicaciones y me he descargado el c\u00f3digo fuente del \u00faltimo n\u00facleo:<\/p>\n
\r\naptitude update\r\napt-get source linux-image-2.6.10-3-686\r\n<\/pre>\nEsto me ha creado diversos ficheros:<\/p>\n

A continuaci\u00f3n he descomprimido el c\u00f3digo fuente original del n\u00facleo:<\/p>\n

\r\nmkinitrd -o \/boot\/initrd.img-2.6.10-686 2.6.10\r\n<\/pre>\nEn el fichero de configuraci\u00f3n del grub (\/boot\/grub\/menu.lst) tendremos que indicar donde se encuentra nuestra partici\u00f3n swap, la cual usar\u00e1 swsusp2 para guardar la informaci\u00f3n cuando hibernemos:<\/p>\n
\r\n...\r\n## ## Start Default Options ##\r\n## default kernel options\r\n## default kernel options for automagic boot options\r\n## If you want special options for specifiv kernels use kopt_x_y_z\r\n## where x.y.z is kernel version.

\r\n# update-grub\r\n<\/pre>\nSi todo ha ido bien, ya tenemos el kernel compilado y listo para reiniciar nuestro PC.<\/p>\n
En el primer inicio con el nuevo kernel tendremos que compilar los m\u00f3dulos de los drivers de Smart Battery:<\/p>\n
\r\n# cd \/home\/user\/Downloads\/acpi_sbs-20050119\r\n# make\r\n# make install\r\n<\/pre>\nSi tenemos un Pentium Centrino, es posible que nos interese instalar tambi\u00e9n el driver para la tarjeta wireless<\/a>. Se descarga el codigo fuente:<\/p>\n
\r\n# tar -zxvf ipw2200-0.21.tgz\r\n# cd ipw2200-0.21\/\r\n# vi ipw2200.c\r\n* Cambiamos la linea 6607 por \"priv->workqueue = create_workqueue(DRV_NAME, 0);\"\r\n# make\r\n# make install\r\n<\/pre>\nTambi\u00e9n ser\u00e1 necesario descargar el firmware<\/a> y descomprimirlo en \/usr\/lib\/hotplug\/firmware\/.<\/p>\n
Ya solo faltan los \u00faltimos retoques al sistema para que todo funcione correctamente, primero a\u00f1adiremos los modulos de smart battery para que se carguen automaticamente en \/etc\/modules:<\/p>\n
\r\ni2c-acpi-ec\r\nacpi-sbs\r\ncapability\r\n<\/pre>\n* El capability se ha de poner tanto si se va a usar Smart Battery como si no.<\/i><\/p>\n
Mi tarjeta de sonido no funciona correctamente con este kernel y curiosamente para que funcione solo tengo que ejecutar:<\/p>\n
\r\nalsactl power 0 D3\r\nalsactl power 0 D0\r\n<\/pre>\nPodemos poner esos comandos en un script de inicio, por ejemplo creamos \/etc\/init.d\/local:<\/p>\n
\r\n#!\/bin\/sh\r\n# Init script\r\n\r\n\r\n. \/lib\/lsb\/init-functions\r\n\r\ncase \"$1\" in\r\nstart) log_begin_msg \"Starting local init script...\"\r\n #start-stop-daemon --start --quiet --exec\r\n cp -f \/etc\/hosts.lan \/etc\/hosts\r\n \/usr\/local\/sbin\/firewall\r\n # Necesario para que funcione el sonido\r\n # (Parece BUG al tener el kernel compilado con swsusp2)\r\n\r\n alsactl power 0 D3\r\n alsactl power 0 D0\r\n #log_end_msg $?\r\n ;;\r\n*) log_success_msg \"Usage: \/etc\/init.d\/local start\"\r\n exit 1\r\n ;;\r\nesac\r\nexit 0\r\n<\/pre>\nAhora ya podemos volver a reiniciar y comprobar que todo funcione correctamente. Podemos ver el estado de la bater\u00eda con el comando “acpi” o con el applet de gnome correspondiente a la bater\u00eda.<\/p>\n
Para hibernar el equipo tendremos que configurar \/etc\/hibernate\/hibernate.conf, a continuaci\u00f3n listo las opciones principales:<\/p>\n
\r\n### swsusp2_15 (for Software Suspend 2)\r\nUseSwsusp2 yes\r\nReboot no\r\nEnableEscape yes\r\nDefaultConsoleLevel 1\r\n# ImageSizeLimit 200\r\n## useful for initrd usage:\r\nSuspendDevice swap:\/dev\/hda5\r\nLoadSuspendModules suspend_swap suspend_lzf suspend_text\r\nUnloadSuspendModulesAfterResume yes\r\n\r\n##############################################################################\r\n### Some global settings\r\n##############################################################################\r\n\r\nVerbosity 0\r\nLogFile \/var\/log\/hibernate.log\r\nLogVerbosity 1\r\n\r\n\r\n### clock\r\nSaveClock yes\r\n\r\n### filesystems\r\n# Unmount \/nfsshare \/windows \/mnt\/sambaserver\r\nUnmountFSTypes smbfs nfs\r\n# UnmountGraceTime 1\r\n# Mount \/windows\r\n\r\n### lock (generally you only want one of the following options)\r\n# LockConsoleAs root\r\nLockXScreenSaver yes\r\n# LockKDE yes\r\n\r\n### modules\r\n# UnloadModules snd_via82cxxx usb-ohci\r\n# UnloadAllModules yes\r\nUnloadBlacklistedModules yes\r\nLoadModules auto\r\n# LoadModulesFromFile \/etc\/modules\r\n\r\n### network\r\n# DownInterfaces eth0\r\nDownInterfaces eth0\r\nDownInterfaces eth1\r\n# UpInterfaces auto\r\n\r\n### programs\r\n# IncompatiblePrograms xmms\r\nIncompatiblePrograms gqmpeg mplayer totem xine xmms rhythmbox\r\n<\/pre>\nPara hibernar simplemente ejecutaremos como root “hibernate”, por ejemplo desde una terminal X. El PC se apagar\u00e1 y en el proximo reinicio se recuperar\u00e1 su estado tal y como se qued\u00f3 (e.g. con el firefox abierto, el OpenOffice con un documento…).<\/p>\n
