installing over previous sabayon installation

Postby 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.
