[SOLVED] No keyboard/mouse in X + hald crashes!

Hello, I've just completed an upgrade and I have no keyboard/mouse in X windows.

/var/log/Xorg.0.log contains the following line at the end:

(EE) config/hal: couldn't initialise context: (null) ((null))

What's more, hald is *not* running, dmesg shows:

hald[2903]: segfault at 0 ip 08057f96 sp bff4db50 error 4 in hald[8048000+50000]

Any attempts to run "sudo hald --daemon=no --verbose=yes" fail with (the last lines)

I have tried downgrading kernel, moving to Xorg 1.6 from testing, nothing works, and I am left with an unusable system. Am I the only one?!? I've run out of ideas! Can anyone help?

Thanks!

Re: [SOLVED] No keyboard/mouse in X + hald crashes!

Add hal to the daemons list in /etc/rc.conf

Re: [SOLVED] No keyboard/mouse in X + hald crashes!

I already have hald in my rc.conf, but since it segfaults, it is never running!!!

I'm really going crazy over here!

Re: [SOLVED] No keyboard/mouse in X + hald crashes!

Well, because of HAL you're missing mouse/keyboard in X, that's for sure. So, the good news is that if HAL is repaired, X will have access to the input devices. The bad news is I don't know what's wrong with your HAL. I'm running the X86_64 port of Arch on my desktop and it runs fine. If noone else reports problem with HAL, usually bad hardware can give you segmentation faults (memory, perhaps... try running a memtest).

Re: [SOLVED] No keyboard/mouse in X + hald crashes!

Of course, but I'm guessing it isn't exactly HAL's fault since there must be something wrong with the 'zero' device HAL is detecting just before the segfault...

/sys/devices/pci0000:00/0000:00:00.0 is a device

And I've just noticed this lspci output. Are these "RAM memory" normal? I'm sure it's the first time I'm seeing them...

It should be hal - not hald. This is mine:

DAEMONS=(syslog-ng hal samba network netfs crond)

Re: [SOLVED] No keyboard/mouse in X + hald crashes!

Yes, yes, sorry, I meant 'hal'.
This is mine:

DAEMONS=(syslog-ng network netfs dbus named @crond @alsa @hal @fam @sshd @openntpd @cups @lighttpd @pulseaudio)

But the problem is that HAL crashes when it runs! It is irrelevant if it is autostarted or not, because it always *crashes*!!!

Re: [SOLVED] No keyboard/mouse in X + hald crashes!

I 'semi-solved' my issue by adding:

Section "ServerFlags"
    Option "AutoAddDevices" "false"
EndSection

to my xorg.conf and specifying by hand the keyboard and mouse device to be used. This is under no circumstances a solution, since I still have no HAL running but hey, I can actually *use* my computer now!

Re: [SOLVED] No keyboard/mouse in X + hald crashes!

I've solved my problem. It seems there was some garbage left in HALs cache, so a

sudo rm /var/cache/hald/fdi-cache

solved my problem once and for all!

Re: [SOLVED] No keyboard/mouse in X + hald crashes!

I was killing myself for an hour to figure out why X input was dead, and traced it to a segfaulting hald which I just couldn't get to run. Just after I found this last suggestion, my hald started working again before I could try it...

Glitches like this amaze me. Since I use GDM, I had to cut the power and boot into single user mode (can't even switch to a VT). I first thought of SSHing in, but because I use networkmanager, which uses hal, that was busted too... hal is a really flaky essential part of my laptop use, and it really bothers me.

I just had the same problem, and removing the cache works
Thanks a lot for the solve

Should we highlight this bug anyway?
