installing over previous sabayon installation

Post by dumay » Thu Aug 02, 2007 14:39

i downloaded the latest loop of sabayon liveDVD 64bit then tried running the livedvd (i have a c2d system so 64bit should work) problem is after sabayon finishes loading the monitor just goes black. so what i did was do a text install which went well, although after loading the monitor still turns black. i tried burning another dvd just incase something went wrong with the other one, this time at 2x speed, but still the monitor goes black.

i downloaded the mini version 32bit, then tried running the livecd and everything seem well. so im thinking it has something to do with my very old monitor and the 64bit edition.

ok, so now i decided to just download the livedvd 32bit edition. will i have to uninstall the previous 64bit sabayon installation? will i have any problems with grub which is on the same partition as the previous sabayon installation? TIA

At the cd /dvd boot menu use the up / down arrows to select the one you want to boot " no music "
then press F5 and some text apears at the bottom above F1 / F2 / F3 you get the idea.

Now add text to the line before the --
res=1024x768
replacing the 1024x768 with a correct reasonable resolution to your screen.
Mine will be res=1440x900
Also add teh video driver to be loaded for yours
xdriver=nvidia
or
xdriver=ati

This should load the correct driver + resolution for your config and then all should be well.

If not sure on the live cd /dvd there is a readme file showing this " cheat codes " you can pass at boot to load / unload stuff.

Code: Select all

This file lists the possible command line options that can be used to tweak
the boot process of this CD.  This lists the Gentoo-specific options, along
with a few options that are built-in to the kernel, but that have been proven
very useful to our users.  Also, all options that start with "do" have a "no"
inverse, that does the opposite.  For example, "doscsi" enables SCSI support
in the initial ramdisk boot, while "noscsi" disables it.

Hardware options:

acpi=on		This loads support for ACPI and also causes the acpid daemon to
		be started by the CD on boot.  This is only needed if your
		system requires ACPI to function properly.  This is not required
		for Hyperthreading support.
acpi=off	Completely disables ACPI.  This is useful on some older systems,
		and is also a requirement for using APM.  This will disable any
		Hyperthreading support of your processor.
console=X	This sets up serial console access for the CD.  The first
		option is the device, usually ttyS0 on x86, followed by any
		connection options, which are comma separated.  The default
		options are 9600,8,n,1.
dmraid=X	This allows for passing options to the device-mapper RAID
		subsystem.  Options should be encapsulated in quotes.
doapm		This loads APM driver support.  This requires you to also use
		acpi=off.
dopcmcia	This loads support for PCMCIA and Cardbus hardware and also
		causes the pcmcia cardmgr to be started by the CD on boot.
		This is only required when booting from a PCMCIA/Cardbus device.
doscsi		This loads support for most SCSI controllers.  This is also a
		requirement for booting most USB devices, as they use the SCSI
		subsystem of the kernel.
hda=stroke	This allows you to partition the whole hard disk even when your
		BIOS is unable to handle large disks.  This option is only used
		on machines with an older BIOS.  Replace hda with the device
		that is requiring this option.
ide=nodma	This forces the disabling of DMA in the kernel and is required
		by some IDE chipsets and also by some CDROM drives.  If your
		system is having trouble reading from your IDE CDROM, try this
		option.  This also disables the default hdparm settings from
		being executed.
noapic		This disables the Advanced Programmable Interrupt Controller
		that is present on newer motherboards.  It has been known to
		cause some problems on older hardware.
nodetect	This disables all of the autodetection done by the CD, including
		device autodetection and DHCP probing.  This is useful for doing
		debugging of a failing CD or driver.
nodhcp		This disables DHCP probing on detected network cards.  This is
		useful on networks with only static addresses.
nodmraid	Disables support for device-mapper RAID, such as that used for
		on-board IDE/SATA RAID controllers.
nofirewire	This disables the loading of Firewire modules.  This should only
		be necessary if your Firewire hardware is causing a problem with
		booting the CD.
nogpm		This diables gpm console mouse support.
nohotplug	This disables the loading of the hotplug and coldplug init
		scripts at boot.  This is useful for doing debugging of a
		failing CD or driver.
nokeymap	This disables the keymap selection used to select non-US
		keyboard layouts.
nolapic		This disables the local APIC on Uniprocessor kernels.
nosata		This disables the loading of Serial ATA modules.  This is useful
		if your system is having problems with the SATA subsystem.
nosmp		This disables SMP, or Symmetric Multiprocessing, on SMP-enabled
		kernels.  This is useful for debugging SMP-related issues with
		certain drivers and motherboards.
nosound		This disables sound support and volume setting.  This is useful
		for systems where sound support causes problems.
nousb		This disables the autoloading of USB modules.  This is useful
		for debugging USB issues.

Volume/Device Management:

dodevfs		This enables the deprecated device filesystem on 2.6 systems.
		You will also need to use noudev for this to take effect.
		Since devfs is the only option with a 2.4 kernel, this option
		has no effect if booting a 2.4 kernel.
doevms2		This enables support for IBM's pluggable EVMS, or Enterprise
		Volume Management System.  This is not safe to use with lvm2.
dolvm2		This enables support for Linux's Logical Volume Management.
		This is not safe to use with evms2.
noudev		This disables udev support on 2.6 kernels.  This option requires
		that dodevfs is used.  Since udev is not an option for 2.4
		kernels, this options has no effect if booting a 2.4 kernel.
unionfs		Enables support for Unionfs on supported CD images.  This will
		create a writable Unionfs overlay in a tmpfs, allowing you to
		change any file on the CD.
unionfs=X	Enables support for Unionfs on supported CD images.  This will
		create a writable Unionfs overlay on the device you specify.
		The device must be formatted with a filesystem recognized and
		writable by the kernel.

Other options:

debug		Enables debugging code.  This might get messy, as it displays
		a lot of data to the screen.
docache		This caches the entire runtime portion of the CD into RAM, which
		allows you to umount /mnt/cdrom and mount another CDROM.  This
		option requires that you have at least twice as much available
		RAM as the size of the CD.
noload=X	This causes the initial ramdisk to skip the loading of a
		specific driver that may be causing a problem.  Replace X with
		the driver name.  Multiple drivers can be specified by a
		comma-separated list.
nox		This causes an X-enabled LiveCD to not automatically start X,
		but rather, to drop to the command line instead.
scandelay	This causes the CD to pause for 10 seconds during certain
		portions the boot process to allow for devices that are slow to
		initialize to be ready for use.
scandelay=X	This allows you to specify a given delay, in seconds, to be
		added to certain portions of the boot process to allow for
		devices that are slow to initialize to be ready for use.
		Replace X with the number of seconds to pause.

Before you format try the last post to see if you can not get it to work or even " nox " option and then install / emerge the video driver you want as root after getting internet connection working and tehn reboot.
Can even as root with nox run " xorgconfig " to get X to work then restart it should load kde and edit /etc/xorg.conf.
Format partion = erase = nothing left , so backup any documents / mp3's / video's you want to keep to a usb / dvd or similar.
You can do the upgrade option in the installer but this will take a long time

whats the default 3.4 livedvd resolution? anyway, this should be a better option that the uninstall reinstall i was planning to do. questioin though, can i do this using a 3.3 mini edition cd? i already gave away my 3.4 dvd. thanks again

Any cd / dvd that is gentoo based / Sabayon based.
res=1024x768 is generally the default but might have to add this so the video card does not get funny idea's.

You must remember your video driver needs to be reinstalled / fixed and then the /etc/X11/xorg.conf needs to be set at same or just below the max screen resolution. Then ctrl+alt+backspace to reload x then it should be happy. You can even try to boot from the live cd /dvd and copy it's settings to your hd for /etc/X11/xorg.conf if you feel they work perfectly there.
Then all should be okay.
Might try to search the forums / wiki on top of this page or if you can not find a fix for the problem try gentoo.org and it's wiki / forums.

Have a look at /etc/X11/xorg.conf usually the # load DRI is there and by removing the # it should enable that feature.

Best of luck.
