[gentoo-amd64] Lost ability to log in graphically

[Jim Seymour]

Hi,

About three weeks ago my kde desktop started to get distorted and slow reacting. I decided to go ahead and reboot the computer. That was the last time I have been logged in graphically. I have since removed KDE and the nvidia-drivers and am now just trying to get it working with the nv drivers and xdm/twm. I do get a log in screen, however upon trying to log in the screen goes blank and eventually comes back to the login screen. Since I seem to be the only one having this issue, I assume I missed an important entry in the elog. I have the modeline (no X at all without a xorg.conf) set to the parameters parsed by the video driver. I am using evdev for the keyboard and mouse (they work fine). I have googled and searched the mail archives to see if anyone else has had the same issue recently and how it was resolved. For the past three weeks I have come up empty. There are no EE entries in the Xorg.0.log at this point. I am running the stable version amd64
 that is completely up to date package wise. The hardware does not seem to be the issue as a gentoo live dvd works perfectly. Any ideas on how I can get this working again? The only worthwhile errors I can find is in the xdm.log are below. This is with a clean xdm.log, reboot, login attempt and then killing X with ctrl_alt_bkspc.

XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"

Weird report.

You might try booting with DRM debugging turned on and looking at
dmesg to see what's going on. I presume that you have a second machine
that you can shell in on.

To turn on debug in grub.conf do something like this, of course
dropping the modeset part if you don't need it:



title 2.6.32-gentoo-r2 MS=1, DRM=0x06
root (hd0,6)
kernel (hd0,6)/boot/bzImage-2.6.32-gentoo-r2 root=/dev/sda2
i915.modeset=1 drm.debug=0x06



This will create a lot of output in dmesg so you may not want to run
with it long term, but it's helped me find a few things over the last
couple of weeks.

Hope this helps,
Mark

Sometimes it takes just rebuilding the device drivers, which can be
found by the gine in the xorg-server ebuild - 

   emerge portage-utils; qlist -I -C x11-drivers/

Take that output and emerge the drivers.

I second this suggestion.

There was an update to xorg a few months ago that required a rebuild
of the drivers, but did not force it.  What happened when I did that
upgrade was that I would get the graphical login screen, but the mouse
and keyboard did not work.  Rebuilding the drivers fixed it for me.

Some observations...

1) Since you get the login screen, X has to be working.  Presumably, 
that's with full root permissions.

2) When you try to login, screen blanks and eventually returns to the ?DM 
login screen.  Of course, in the process of logging in as your user and 
getting a kde or twm session, you'll switch to user privs for some 
things.  That this doesn't work but the login screen as root does, hints 
at a permission issue, or an issue setting up the user "magic cookies" 
that allow an ordinary user to access the xorg server running as root.

3) That begs the question [1], what happens if you create a fresh user and 
try to login as them, and/or if you try logging in as root? (Yes, I don't 
recommend it for normal usage either, but for testing... disconnect from 
the net if you're paranoid, backup your /root so you can restore it to pre-
X-login condition afterward, and try the root thing.)  If a new/clean user 
works, then you know it's something in the user config.  If it doesn't but 
root works, you know it's a permissions issue of some sort.

4) Due to ?DM breaking on me years ago on Mandrake, I quit using ?DM 
graphical logins then, and have never gone back, choosing instead to login 
at the text console and startx as my preferred user.  You mention nothing 
about even trying that.  Does /that/ work and you simply prefer the 
graphical login, does that not work either, or were you unaware of the 
option?

Obviously if it works you have a workaround.  At least that way you can 
run your graphical environment of choice, even if you don't like the login 
method.  Plus, the results of this test should help someone a bit more 
skilled in ?DM technologies than I am (as I said I quit DMs long ago) 
figure out what's going on.

As a very curious and probably unrelated report I did updates on my
wife's machine last night. I did not reboot or restart X when I Was
done. When she turned it on this morning X didn't work for her.
Curiously it's the only nvidia machine here.

In her case gdm was not starting so it's likely not the same thing you
are seeing, but I got some messages that the nvidia driver was not
matching the kernel. The kernel wanted 185 something, the new emerge
had installed 190 something.

I masked everything above what's in portage right now for 185 + a
little and reemerged the drivers and it started working again.

and you checked ALL permissions of ALL files (inclusive root dir) of /tmp and 
/var/tmp

Hi,

Thanks for the ideas so far. I had already tried startx and that fails and comes back to the command prompt. I have tried the re-emerging of the drivers and even gone as far as running ldd against X and another package I forgot the name of and re-emerged the packages that contained the files that it it linked against as well as re-emerging those packages. I too had run into the nvidia and kernel headers issue when I tried to downgrade the nvidia driver. That was the real reason I dropped back to the nv driver while I was sorting this out, I have all of the right pieces together to run the nvidia driver but want to keep that out if the mix for right now.

I have not tried the debugging setting or the new user. Off to try those now.

Thanks to all,

Jim

Re: [gentoo-amd64] Lost ability to log in graphically

Hi All,

Problem has been resolved, however I am not positive what worked. As the situation was, I could not log in graphically with any user, root included. I had recompiled all x11 drivers as well as the kernel and every package I found /usr/bin/X linked against, recompiled hal, etc. All this and no fatal errors in the Xorg.0.log :-( On this final try I rechecked the config files for xdm, Xsession, xorg.conf and a few others and made a few tiny changes. I also went ahead and recompiled the x11-drivers again and one I had not recompiled prior to now ..... mesa. The problem was definately with one of the programs that was recompiled, however I can only suspect which one. Many thanks to all the suggestions. I did learn a couple of new tricks out of this. Now to get KDE reinstalled and go back to the nvidia driver.

Thanks again,

Jim
