Moving from 2.4 to 2.6 guide

[surf27]

Good news; badnews. Linux does not yet support DRI on Savage 4 video cards. ref: http://dri.sourcerorge.net. I have the same problem.. I'm getting a GeForce TI4200 card as soon as I can> Cheers.

Is a ProSavage a Savage4? I'm really uneducated on the whole S3 line, sadly

Hey I went to 2.6 and when my computer boots all the text is garbled but after a few seconds it is all clear again

I just upgraded from 2.4->2.6 I was running LVM on 2.4 and I uninstalled LVM and emerged LVM2. Now when I boot, the LVM manager doesn't even start. Does anyone know why this could be or a way to fix it? I enabled multi-device support and whatnot as this thread suggested but nothing is working.

I am going to type out the errors:

It gets to *Mounting local filesystems...

then says

mount: special device /dev/vg/usr does not exist
mount: special device /dev/vg/var does not exist.
mount: special device /dev/vg/opt does not exist.
mount: special device /dev/vg/home does not exist

* Some local filesystems failed to mount

few more lines, then:

Could not create needed directory '/var/lib/init.d/softscripts'!
Could not create needed directory '/var/lib/init.d/snapshot'!
Could not create needed directory '/var/lib/init.d/options''!
Could not create needed directory '/var/lib/init.d/started'!
ln: creating symbolic link '/var/lib/init.d/started/checkroot' to '/etc/init.d/checkroot': No such file or directory
Gives about 4 other /var/lib errors
then
localmount': No such file or directory
/sbin/rc: line 376: install: command not found
/sbin/rc: line 421 install: command not found

then a ton of other ln: errors with /var/lib

Does this help at all?

Gentoo doesn't try to start lvm unless it detects that you have lvm support. That means you probably want to do things like add dm_mod to your autoload. Is there a doc on this?

is there a way to somehow move the old kernel-config to the new one. the thing is that i'm not so sure about all the things i need to put into the kernel....HELP

It takes a while for my mouse to start working, after I move it around a few times then it acutally works. How do I actually make it more responsive?

This works for me...

cd /usr/src
cp linux/.config /usr/src/linux-2.6.1-rc1/ (- to location of new kernel)
cd
ls -l /usr/src/linux
rm /usr/src/linux && ln -s /usr/src/linux-2.6.1-rc1/ /usr/src/linux (- linux-2.6.1-rc1 represents the name of the new kernel)
ls -l /usr/src/linux (- to check the symlink)
cd /usr/src/linux
make oldconfig
make && make modules_install
mount /boot/
cp arch/i386/boot/bzImage /boot/kernel-2.6.1 (- or whatever name you give it)

Edit /boot/grub/grub.conf to point to the new kernel
Reboot

emerge nvidia-kernel
emerge nvidia-glx
reboot

Can someone show me an example of what they added to their grub config in order to boot kernel 2.6.

[elec999]

Can someone show me a sample config of their grub with the new kernel 2.6.3.
Thanks

I have a system set up and working under 2.4.25 using lvm. I am using either ext3 or reiserfs (depending on the box's purpose) for all filesystems on all my machines; this box uses ext3. The only non-lvm filesystem is /boot, which is a primary partition formatted as ext2. Even my swap is under lvm,

Now I discover that to fulfill this machine's purpose in life, I have to run it under a 2.6 flavor of kernel.

I need the 2.6 kernel because this machine is destined to be an ipsec tunnel server, and I apparently need 2.6 to support all the modes I need. It must be able to accept a connection from a dynamic ip on a box running various microsoft os's, Mac OS-X, and various linuxes and bsd's. It is basically going to be a VPN tie point for a bunch of diverse road warriors, so they can all access the home network, and all appear to be on the same lan with each other when they are connected. In particular, remote roving laptop video conferencing must be supported. NAT traversal is deliberately being avoided for now, because some of the clients do not support it.

All that is mainly to explain why I have to use 2.6 after I had a basic system up and running 2.4.25.

I use rsync for backup, and I have been configuring all my other boxes to run 2.4.25 and lvm so I could use the snapshot feature of lvm to freeze the filesystems during backup operations.

If I cannot do snapshots under lvm-2 on the 2.6 kernels, then I will have to forgo lvm altogether on the vpn server, as I need the 2.6 kernel to support the ipsec vpn tunnel stuff worse than I need snapshotted backups.

Does lvm-2 under a 2.6.* kernel support snapshots yet?

I have already posted this in "networking," but since
it happened as a result of updating the kernel from 2.4
to 2.6, maybe somebody here will have an answer for
me. :)

After I upgraded the kernel, all the things that I had
worried the most about (sound, video, changing to
udev) worked flawlessly. What failed? SSH!
