Very slow after update to mdk10.1

[Landy]

Just updated my system which was 10.0 to 10.1 CE from a magazine DVD. Once it got updated, it took me to the KDE log in screen, but took ages to load up. Stayed on the splash screen after login for about 5 minutes at least.

I think it may be to do with the shorewall or network device having problems. I'm on broadband so my eth0 is connected to my cable modem.

Any ideas?

Is it just as slow every time you log on, or was it just the first time?

[Landy]

It does it everytime, and the internet is painfully slow too. The connection seems fine. I seem to recall something about IPv6 on some website one time. Could this be causing my slow browsing and slow boot up?

[TheCatMan]

I don't know about ipv6 but I've had something similar under Mandrake 9.2. When I first installed I changed my machine name from localhost to magrathea and, for some reason while I was setting up a new connection recently, Drakconnect removed the alias magrathea from /etc/hosts. This made starting X noticeably slower, but was easily cured by changing the first line of /etc/hosts from
127.0.0.1 localhost
to
127.0.0.1 localhost magrathea

I don't know if that would affect the internet tho.

HTH

Have you tried backing your data up and doing a fresh 10.1 install? Upgrading usually doesn't work too cleanly.

[Choozo]

I was thinking along the same lines, unless he has /home on a separate partition (don't need to back up much then) :)

Upgrading, instead of a fresh install, usually leaves a lot of "lint" that will slow things down (despite what Mandrake may say) :p

[Landy]

To be honest, I've never backed up a Linux system before, so I wouldn't know where to start.

All my Linux things are on the same partition, but one good piece of news is that I recently bought a DVD writer so less burning to do.

[Choozo]

You would back up files in /home (all users), and any other files that you have added elsewhere - e.g. webpages you have made?

Any system configuration files you have changed in /etc would also be candidates for a backup.

No need to back up any programs, as these would be reinstalled anyway.

[Landy]

Ok, I backed up, reinstalled and now its got other problems!

Just to list them:

KDE keeps locking up
The net is still really slow (its quick enough in XP)
The sound cut off once

On a small plus side, the boot up is quicker, but not as quick as it was before I tried an update.

I'll have to fine tune my system. It keeps knocking my modem off though. I've got broadband with NTL through a cable modem and if I bring the eth0 up and down a few times it turns the modem off and won't get a signal.

Argh!

For the KDE problem; rename your ~/.kde directory.

Before logging in, go to a virtual terminal using Ctrl+Alt+F1 and then log in at the loginprompt there:
$ mv .kde .kde_old
Log out of that console, go back to the kdm loginscreen (Alt+F7) and log in as usual.
Should fix the KDE problem.

Move any mail-, browser-directories from .kde_old to .kde as necessary.

[Landy]

Cheers I'll try that later on tonight. Just hope my modem is back on. :rolleyes:

I stumbled across this (http://linuxformat.co.uk/modules.php?op=modload&name=phpBB_14&file=index&action=viewtopic&topic=10472&forum=1&1) earlier.

I had this problem before with my broadband connection and Mandrake.
This was the advise that I got and it worked for me.

{If you want to disable ipv6 you just add the following line to either /etc/modules.conf for 2.4 kernel or /etc/modprobe.conf for 2.6 kernel.

alias net-pf-10 off

If the broadband connection seems slow.
Browse to the usr/etc.

ls
gedit ./modprobe.conf


At the end add: alias net-pf-10 off
Save and close: Reboot.

Ahh, I'd tried that IPv6 bit before I did a complete reinstall. Didn't seem to do anything but that other bit about modprobe I haven't tried. I like having things to try, its so much better.

Let us know how it turns out, I'll be upgrading to 10.1 before too long, also from a magazine DVD. 50% chance it's the same mag as yours :D
