problem loading KDE after updating portage

[mesman00]

ok, i just updated my linux system by doing "emerge -u system". After it was done compiling and installing all the new ebuilds, i updated my config files as i was directed. then, after restarting my computer linux wouldn't start kde. when i typed "startx" i get the following error:
failed to initialized NVDriver module in kernel

is it possible that i have to change something in my XF86Config file because updating the system intalled new drivers? right now in my XF86Config file my driver is "nvidia". It has worked liked this fine up until i updated all my ebuilds. Any input would be great. Thanks.

Try running the NVmakedevices script. Not quite sure of the name, it is either in /sbin or /usr/sbin somewhere. If that does not work you need to add the nvidia module to /etc/modules.autoload.

 

[Slougi]

OK, just checked bu SSH'ing into my PC

The script is called NVmakedevices.sh and is in /sbin.

Mesman: Wouldn't you be better off searching the gentoo forums? Just a thought...

BTW Slougi, shouldn't XF86 automatically load the driver module if it's correctly configured to do so in XF86Config? Why should it be in modules.autoload?

 

[Slougi]

Yes it should always do that *theoretically*, and it used to work fine. Some update to baselayout and/or devfs however caused some breakage, so that one of the two things I mentioned above needs to be done for it to work correctly. It's a widespread problem, just search the gentoo forums.

do an lsmod to see if the modules loaded up
do an opengl-update nvidia
make sure you have your XF86Config file setup properly (from the error it sounds like you do)

try to run it again

i ran the script, tried to start x, and got the same errors. How should it appear in the modules file?

what exactly is "Ismod". anyways, i tried opengl-update nvidia and it still doesn't work. everthing as far as i am concerned is set up correctly in the XF86Config file. oh yah, i did post this on the gentoo forums, but they were of no help. i only got one response. that was it. so i came here

 

[Malcolm]

its not Ismod it lsmod (with an L)

It lists all loaded modules, if NVdriver isn't loaded then you'll always get an error on loading XFree86

 

[mesman00]

the nvidia module isnt loaded...there are no modules loaded as a matter of fact, becuase my modules.autoload file is empty (except for a few instructions at the top). so, how do i add nvidia to my modules.autuload file? what does it have to be entered as?

 

[Slougi]

What happens when you try to load the module? (modprobe nvidia or modprobe NVdriver, depending on driver version)

If it works you should be able to start X. And modules.autoload is just a text file where you can add modules (drivers) to be loaded on boot. Just add the driver name to it, in this case either nvidia or NVdriver. Here is some info from my computer:

Gondolin root # cat /etc/modules.autoload
# /etc/modules.autoload.d/kernel-2.4:  kernel modules to load when system boots.

ok after adding the module and editing the make.conf and the rc.conf file i was able to bring kde back up. however, i no longer have internet connection, even though when the kernel is loading it says that eth0 was brought up sucessfully. also, when i log into my user account using kde and open a konsole, it won't let me switch to the root user. instead it says permission denied. i had this problem before, and i know there's something i have to change in the user settings, but i don't exactly remember what. thanks for the help so far.

 

[Malcolm]

find your net.eth0 and make sure that dhcpcd is assigning everything, I can't remember how to do this off hand and I'm at school but I think its somewhere in the Gentoo install docs.

About the root stuff, no idea
/me looks at Slougi

btw, when you want to make sure that all of the packages on your system are up to date, do "emerge -U --deep world" rather than system. System refers to the core components, where world refers to all major packages. Also, --deep checks all dependencies, rather than just the immediate ones that are flagged for updating when any given package is updated.

Baselayout 1.8.6.8 is broken, I had the same problem. Downgrade to 1.8.6.7, reboot, emerge sync, emerge baselayout 1.8.6.8-r1. If needed boot from gentoo livecd and chroot.

http://bugs.gentoo.org/show_bug.cgi?id=21376

< edit >

From your description (now that I read it properly) It seems like you might have replaced /etc/groups, or something similar. Possibly you need to readd your user to the wheel group.

usermod -g users -G wheel [user]

 

[mesman00]

hey slougi...how do i downgrade from the livecd?

 

[Slougi]

Boot from CD, set up networking, mount partitions, chroot (same as when you installed), use emerge as always

 

[mesman00]

heres the deal, i messed with something i wasn't supposed to, becuase now after emerge baselayout, when i try to load linux i get the following error after going through some of the loading process:

kernel panic: no kernel init!!

insteading of emerging after setting up my network card and mounting my drives, i did.

tar -xvjpf /mnt/cdrom/gentoo/stag1-*.tbz2
mount -o bind /proc /mnt/gentoo/proc

and unpacked the stage1 tarbell. it wasn't until after this that i did:

chroot /mnt/gentoo /bin/bash
evn-update
source /etc/profile

and emerged baselayout

could this be the reason that is causing my newfound problems? any help would be great, and thanks for all the help so far. i guess the only way to learn things is by fuxoring them up.

Ack :|
Basically you will need to bootstrap again at this point, maybe emerge system. emerge sync before this though, so you get the new fixed baselayout.

True. Or having a system where you do not have super user rights, and a broken tcl and gcc, and you need to compile an eggdrop :doh:
That's how I learned my stuff mostly

 

[mesman00]

this bootstrap you speak of, can i get some more details.
