[gentoo-user] no keyboard no mouse

[gentoo-user] no keyboard no mouse

[alain.didierjean]

After upgrading xcb, ati driver and rebooting xorg can't read mouse and keyboard
anymore. No more access to the system besides booting an unbuntu livecd.
According to /var/log/Xorg.0.log, evdev cant't be loaded any more (see below).
What can I do ? Is there an upgrade to evdev ?

A emerge -1 x11-drivers/xf86-input-evdev should do the trick.

No you just need to rebuild it, so emerge xf86-input-evdev

Did you try remerging evdev? I believe there's another package you need
to reemerge also, I can't remember off the top of my head. If some one
else doesn't chime in by the time I wake up then I'll look it up.

If you use portage 2.2, emerge @x11-module-rebuild

This problem hit me too.  Can you give us an explanation for needing to
rebuild evdev?  Was there some missing dependency in an ebuild, or
something?

It is sort of like when you update a kernel and have to rebuild the 
video drivers.  One is built against the other and when you upgrade, you 
have to update the things it was built against.  There are other 
examples of this but this is just the first one I thought of.

Anyone recall expat?  That I think is another.

If you update xorg (which OP didnt list, but a new version just went
stable) you need to rebuild its drivers (unless they were
automatically rebuilt due to version bump).

I think portage should take care of that... but obviously it doesn't
I solved the problem by rebuilding xf86-input-evdev after booting on an unbuntu livecd then chrooting... Took some time.
As for using portage 2.2, it's listed as ~*2.2.0_alpha41, too early for me. 
Thanks all for the help

Make an entry in your grub.conf with gentoo=nox, so you can boot to
command line. here's what mine looks like

title Gentoo Linux 2.6.39-r1a
root (hd0,0)
kernel /boot/kernel-2.6.39-r1a root=/dev/sda3 usbcore.autosuspend=1

title Gentoo Linux 2.6.39-r1a Console
root (hd0,0)
kernel /boot/kernel-2.6.39-r1a root=/dev/sda3 usbcore.autosuspend=1 gentoo=nox

Hmm.  Recompiling the same source code produces a different binary?
Presumably, it uses C macros in a .h file which is part of xorg.  Or
something like that.

So evdev depends on xorg.  Isn't there a way of expressing this in
evdev's ebuild?  Something like the DEPEND variable?

Not quite:

Rebuilding the same sources against different headers produces a 
different binary.

It's already there, but doesn't help as the update trigger never 
happens.

Actually, you have the depend the wrong way round - evdev depends on 
xorg-server; to have the driver and for it to be useful, the xorg-
server must be present, otherwise there is nothing for the drivers to 
build against.

You want to force a rebuild that is the opposite of the DEPEND, but 
portage does not support that (it's a circular dependency). It will 
also not rebuild the driver as part of a regular update as there is 
not a new version of the driver, hence according to normal portage 
logic there is no need to do so.

Make sense?

Why did you need to chroot, just boot your normal system without X (add
gentoo=nox to the kernel paramaters).

Don't let the ridiculous version number fool you, 2.2 has been
generally usable for a couple of years.

+1   I been using it here for a good while now.  Other than the

Honestly, the "alpha" designation also made me shy away from 2.2

Really, someone should rebrand that as "beta", if 2.2 is indeed usable
for a couple of years.

That said, thanks for the heads-up. I'll unmask it on my systems :-)

It's not alpha as in alpha

The rc point releases hit -99 sometime ago so Zac switched to a 
different prefix. Most other projects would have been a release by 
now.

Why did you need to chroot, just boot your normal system without X (add
gentoo=nox to the kernel paramaters).

Didn't remember the option in these times of panic (I had some task to achieve rapidly). It's now an entry in grub.conf

Don't let the ridiculous version number fool you, 2.2 has been
generally usable for a couple of years.

Oooops, I stupidly thought that "alpha" in version name, which usually doesn't appear, meant a specially risky version in alpha state... Silly me.

I think so - I've always had problems understanding dependencies.  What I
want is one of these "nice to have"s which would take an inordinate
amount of work, if it's even possible.

In the meantime, I'll carry on not starting Gnome at boot-up.  Despite
the existence of gentoo=nox, I feel safer starting it manually.  It's a
strange, depressing feeling when the only input device which works is the
reset button - thank goodness that isn't handled by evdev.  ;-)

I'd say the sillyness is in the version number. 2.2 (we're on 2.2.0 now)
reached the milestone of 99 release candidates, which is farcical.

Hmmm.  Yes.  The problem is not so much the reading, but that the
pertinent text is only fleetingly on the screen.  I'm quite sure I saw
these warnings, but their seriousness didn't impinge on my consciousness.
Sadly.

Are these warnings stored in a log anywhere?  Looking for them in ebuilds
before emerging would be a bit tedious.

Or maybe it needs a script which would take the output of "emerge -puND
world", extract the ebuild names, and run them through "grep ewarn".  Or
does such already exist?

There are tools for that:

That should help.  I liked it when all the messages like that were saved 
until the end of the emerge then displayed.  I rarely sit and watch for 
the stuff scroll by anymore.

Trouble with dependencies is they present themselves the wrong way 
round when you try to debug them. It's the classic grandfather 
problem:

I ask you "who is your granddad?", that's an easy one, you say it's 
John Smith. Now I go find John Smith and ask him "who's your 
grandson?" He says "I have more than one. Which one you interested 
in?" and you can't answer that without more information.

When you look in an ebuild for DEPENDS, you are using the first case. 
When you try debug portage output, you often end up at the second 
case.

I imagine the real reason portage doesn't have excellent tools to help 
answer that is becuase the problem is infernally difficult to do 
correctly, and the output will always be mind-bogglingly confusing.

Moving a little off-topic, I have a similar thing at work. A perfectly 
valid question I often get asked is "when did we last receive a mail 
to xyz@company.com?" HR want to know this so they can know when to 
retire an address. I can't tell them, not without an exhaustive manual 
search of mail logs.

Yup, loss of input devices in the most annoying pain in the arse 
imagineable. Remember when xorg was a huge monolithic code base and 
you always got everything every time, but the dependency issues just 
simply never happened?

those warnings ARE stored.

For the ultra lazy way:
PORTAGE_ELOG_CLASSES="warn error log"
PORTAGE_ELOG_SYSTEM="mail save"
PORTAGE_ELOG_MAILURI="root@localhost /usr/sbin/sendmail"
PORTAGE_ELOG_MAILFROM="portage@localhost"

and then have the stuff dumped in your mailbox.

Please use the > mark for quotes or it's a pain to read your reply.

Using "Ctrl + Alt + SysRq + key" by passes Xorg and gets handled by the kernel.

I used the same key combo to fix my Xorg drivers the other day. Yes I know I should of read the elog.
With the key combo you need to hit all 4 keys at the same time or it does not work.
