How to disable HAL and still use X in Slackware64-13 ?
 
I did what is recommended in CHANGES_AND_TXT:
Code:
If you prefer to do this the "old" way
  using /etc/X11/xorg.conf, then you can use "X -configure" or "xorgsetup" to
  generate an xorg.conf, then add the following lines to the "ServerFlags"
  section to disable input device hotplugging via HAL:
    Option  "AllowEmptyInput"    "false"
    Option  "AutoAddDevices"      "false"
    Option  "AutoEnableDevices"  "false"
  This is also relevant if you prefer to disable HAL completely for whatever
  reason.
I already had an /etc/X11/org.conf file because I use a NVIDIA driver for my graphical card.

So I edited it, appended following lines at the end:
Code:
Section "ServerFlags"
    Option  "AllowEmptyInput"    "false"
    Option  "AutoAddDevices"      "false"
    Option  "AutoEnableDevices"  "false"
EndSection
But then if I do not start hald, X fail to start and I have these messages in /var/log/Xorg.0.log:
Code:
(EE) config/hal: couldn't initialise context: unknown error (null)

Backtrace:
0: /usr/bin/X(xorg_backtrace+0x26) [0x4eb2d6]
1: /usr/bin/X(xf86SigHandler+0x39) [0x471f79]
2: /lib64/libc.so.6 [0x7f192ac82f30]
3: [0x7d64f0]

Fatal server error:
Caught signal 11.  Server aborting
Do I miss something, maybe in X configuration, to "tell" the X server not to rely upon HAL ?

PS this a "how-to" question, I do not expect answers like "why don't you use HAL?" -- there is already (at least) one thread about that anyway.

If you check /etc/rc.d/hald messagebus and mysql, I would guess that the files will be empty. These are the symptoms that I saw and I had to do a full re-install to fix the problem. I think that it is a wider problem but I couldn't find a way to fix it.

Didier Spaier 09-10-2009 01:09 PM
Thanks Samac, but /etc/rc.d/hald, /etc/rc.d/messagebus and /etc/rc.d/mysql scripts are present in my installation and work, AFAIK. I can stop or start hal (and dbus and mysql) without any issue.

adamk75 09-10-2009 01:17 PM
Can you show us your full /var/log/Xorg.0.log file and your /etc/X11/xorg.conf file? Because, honestly, those options should be all you need to disable Xorg from using HAL.

Yes.

I think its because the nvidia-generated xorg.conf does not contain enough to start the x-server. You will have to run xorgsetup to generate a complete xorg.conf file. Then, re-installing the nvidia driver will prompt you to allow the installer to add the nvidia related options to xorg.conf. The last step will be to manually edit xorg.conf for your mouse and screen resolution - especially if you have a wide screen.

Didier Spaier 09-10-2009 02:24 PM
I ran xorgsetup with no more success. X stops as soon as I try to use an input device, with the same messages in Xorg.0.log.

Thanks anyway - also because running xorgsetup I found out that I could use "thinkpad60" as "XkbModel" which is more accurate than "pc105" for my Lenovo Thinkpad T61's keyboard.

GazL 09-10-2009 02:40 PM
I have exactly the same issue as Didier here. X displays ok initially (Windowmaker from startx), but the instant you move the mouse or press a key it dies just as Didier's has. But only when hald isn't running.

adamk75 09-10-2009 02:41 PM
You have

Code:
    Option        "AllowEmptyInput" "false"
    Option        "AutoAddDevices" "false"
In two different sections. I doubt that this would be the source of the problem, but it's worth removing them from one of the two sections to find out. Either section is fine as those options should work in either ServerLayout or ServerFlags.

Adam

Didier Spaier 09-10-2009 02:50 PM
Thanks for the suggestion, however these lines are not duplicated in my last xorg.conf (output of xorgsetup) and I get the same results.

GazL 09-10-2009 02:52 PM
I've just figured it out. Insipration out of the blue.

You also need to stop messagebus. If you run messagebus without hal then it goes BOOM!

Didier Spaier 09-10-2009 03:28 PM
Thanks Gazl, same here.

I thought I would still need dbus though to have a few KDE apps working -- even if I use Fluxbox as WM -- but notwithstanding a few warnings at konqueror start up kontact as well as konqueror still seem to work.

Didier Spaier 09-10-2009 03:48 PM
To be more accurate, these KDE apps somehow launch dbus when they need it.

I saw that with "top" command: as soon as I launch kontact or konqueror as user didier, I see dbus-launch and dbus-daemon which appear in top's window.

But in that case X don't crash.

Good to know, though I would like to know why.

GazL 09-10-2009 03:54 PM
Yes, its annoying. I don't like HAL that much but I can see the value in dbus and as you say, things like kde rely on it quite a bit, so having to turn it off is a pain. I found a /etc/dbus-1/system.d/hal.conf file and thought that by removing that it might allow dbus to still run while allowing X without HAL, but it didn't make any difference.

I guess the Xorg code just isn't checking return values properly on their messagebus calls and subsequently bombing out. :(


The reason I was trying to run X without HAL is that I've found that when using the Virtual Consoles after exiting an Xserver screen, key-presses are going astray making it unusable until I restart X again. Interestingly, while X is still running (even if only showing a XDM), or when X is restarted, the key-presses work correctly in the VC. It's only after you exit X that the problem happens. Also, the same thing occurs on OpenBSD 4.6, so it's not linux specific, but something is upsetting keyboard handling somewhere. I wanted to see whether turning off HAL made any difference - It doesn't! This is using a Chicony HID wireless keyboard and mouse. I've not tried plugging in a cabled PS2 keyboard yet, but that's my next step. I suspect the problem may go away when I do that, but we'll see.

All things being considered, I looks like X.org is going through a bit of a rough patch at the moment. Lets hope it gets back on track sooner rather than later.

There are two dbus daemons. A system wide one and one for your current session, which is the one dbus-launch starts. I'm not sure if the session specific one will work without the system level one being up. I've not really looked into dbus all that much.
