[SOLVED] Thunar does not automount USB stick in Windowmaker on Slackware64-current

allend · 03-10-2016, 07:04 PM

Can anybody else replicate this corner case of Thunar launched in Windowmaker on Slackware64-current (as at 9 March 2016) not automounting USB sticks when plugged?
This is a little weird to me, as:
Thunar launched in XFCE on the same system behaves as expected.
Dolphin launched in Windowmaker on the same system behaves as expected.

Thunar launched in Windowmaker on 32bit Slackware-current behaves as expected.

I have taken the lack of answers as a No.

I just rebuilt my proprietary nVidia graphics driver and the problem has gone away. Go figure!

Just an update on this since upgrading to Slackware64 14.2-RC2.

Following the upgrade to the 4.4.7 kernel, I patched the kernel source and rebuilt the generic kernel to suit the nVidia 304.131 driver that I use. http://www.linuxquestions.org/questi...it-4175576863/

For kicks, I rebuilt the thunar-volman package from source and reinstalled, and the problem went away.
I then reinstalled the thunar-volman package from my local Slackware mirror, and the problem returned.
Reinstalling the locally built thunar-volman package made the problem go away again.

As this does not appear to be affecting anybody else, then it is obviously not a big issue, but perhaps thunar-volman could do with a recompile before Slackware 14.2 is released.

Further update:
Compiling locally shows some additional links in /usr/bin/thunar-volmam and /usr/bin/thunar-volman-settings to the nVidia driver.

Code:

ldd
...
        libnvidia-tls.so.304.131 => /usr/lib64/../lib64/tls/libnvidia-tls.so.304.131 (0x00007f0a57cae000)
        libnvidia-glcore.so.304.131 => /usr/lib64/../lib64/libnvidia-glcore.so.304.131 (0x00007f0a558c4000)

My apologies that this is a blog post, but this is getting on my goat. The previous fix did not stick.

The fundamental problem seems to be the setting of the DBUS_SESSION_BUS_ADDRESS environment variable. This affects both WindowMaker and FVM2 when booting to run level 4.

When I boot to run level 3, the DBUS_SESSION_BUS_ADDRESS environment variable is set for KDE, XFCE, FluxBox, WindowMaker and FVWM2, so all is OK and Thunar recognises the plugging of a USB stick.

When I boot to run level 4 using kdm as the login manager, then both WindowMaker and FVWM2 do not see the DBUS_SESSION_BUS_ADDRESS environment variable set (unlike KDE, XFCE and FluxBox), so Thunar does not recognise the plugging of a USB stick.

This can be worked around by adding 'dbus-launch ' in front of a call to Thunar, but this is a kludge that was not required until recently for reasons that I cannot elucidate.

I have looked at this some more and have discovered that the following changes allow WindowMaker, FVWM and Blackbox to see the DBUS_SESSION_BUS_ADDRESS environment variable when started from run level 4 using kdm.

For WindowMaker:
1. Create a file /usr/bin/startwmaker (I copied the existing /usr/bin/startblackbox and edited) containing

Code:

#!/bin/sh
#  startwmaker v1.0

########################################################################
##  Start DBUS session bus                                            ##
########################################################################


if [ -z "$DBUS_SESSION_BUS_ADDRESS" ]; then
   eval `dbus-launch --sh-syntax --exit-with-session`
fi


########################################################################
##  Start wmaker Window Manager                                       ##
########################################################################


exec /usr/bin/wmaker


########################################################################

2. Edit /usr/share/apps/kdm/sessions/wmaker.desktop to read

Code:

[Desktop Entry]
Type=XSession
Exec=startwmaker
TryExec=startwmaker
...

Comment - A similar fix probably applies to TWM and MWM.

For FVWM:
1. Edit /usr/share/apps/kdm/sessions/fvwm.desktop to read

Code:

[Desktop Entry]
Type=XSession
Exec=startfvwm2
TryExec=startfvwm2
...

For Blackbox:
1. Edit /usr/share/apps/kdm/sessions/blackbox.desktop to read

Code:

[Desktop Entry]
Type=XSession
Exec=startblackbox
TryExec=startblackbox
...
