PostPosted: Tue Sep 11, 2012 3:34 pm    Post subject: xfce can't control display[solved] Reply with quote

Hello, this problem has bothered me for a long time.

I am running xfce 4.10 on my laptop. After starting the xfce, the xfce power manager can't control the display by defaul, for example, reducing the brightness, switching off the monitor if the laptop is inactive for the time that I set in the preference.
However there are two ways to make it work:
The first is to open the xfce4 power manager and change the time and close. Then the power manager could reduce the brightness of display, put the monitor on sleep and switch it off.
The second is to unplug in and replug in the laptop the ac adaptor. The function comes back too.

So, I want to know what I could do could make the power manager work properly?

Thanks

Environment:
kernel: gentoo-3.5.2
Desktop: xfce4.10
xfce power manager version: 1.2.0

If you unplug it and power manager starts working, maybe it's set to not change the display while plugged in?

I am afraid not. In fact, if I just unplug it, power manager doesn't work either. It starts working after I re-plugin it.

I found the problem but I don't know how to fix it

Here are some other ways to make power manager work properly again.
1. quit xfce4-power-manager and restart it again, it will work well
2. run "session and startup" manager, go to tab "session", and change power manager restart style to never or immediately, then when I log in next session, it will work well
3. if I run xfce4 as root, power management will run it perfectly, smoothly.

so, could anyone have some ideas please?

Do you get any interesting messages if you run the power manager from a terminal?

No, there is nothing, after running xfce4-power-manager in terminal, it gives nothing. Programme starts and the cursor comes back.

Make sure xfce4-power-manager is not running already using "ps"; kill any instances (you may have to revert your setting for restarting it under session dialog). Then invoke in a terminal:

Code:
# xfce4-power-manager --no-daemon --debug --dump

What do you mean by "using ps"?

It quits after this output? What if you run it as root?

If it continues to operate when invoked as root, then the problem is permissions.

In the dump it indicates that it was not built with policykit support. AFAIK, you need this support for xfce4-power-manager to "just work."

Please confirm that the "policykit" USE flag is enabled. If isn't, enable it, and rebuild anything affected by this USE flag. Then log out/log back in and see how it works.

I though of the permission issue too, but I didn't know there is policykit USE flag for power-manager. I re-emerged with policykit. problem solved. Thanks a lot.

I am sorry, I was wrong, it doesn't solve the problem perfectly. In fact, it only solved the problem with brightness control, but it can't turn off the display after the time that I set. here are the information that I got after running the same command you told me

Can you turn off the screen by invoking

Code:
# xset dpms force off


on the commandline? If that doesn't work, xfce4-power-manager won't be able to turn off the screen as it uses the same method.

You can also double-check that X respects the DPMS timing settings (see the xset man page)

yes, of course. this command can turn off the screen.

when I said it doesn't work, I mean, it can't turn off the screen just after restarting a new session. but It works when I restart the xfce4-power-management in the same session.

It seems like you're still having a permissions problem originating with xfce4-session, though it's not immediately clear from your debug output what exactly that problem is.

You mentioned that you rebuilt xfce4-power-manager with the "policykit" USE flag; did you remember to rebuild all the packages with this USE flag? This includes xfce4-session.

You may also need to enable the "consolekit" USE flag if you have not already done so. xfce4-session has a USE flag for this as well.

Thanks a lot. I will even try to rebuild all packages with these two consolekit.
However, if it's like what you said, why the power-manager works very well. I restart it under normal user.

I just tried, it doesn't fix the problem.

I add consolekit and policykit as the global USE flag and update all packages with them, including xfce4-session. As you mentioned, xfce4-session wasn't compiled with the 2 USE flags last time.
To be sure, I re-emerge again xfce4-power-manager. Then I restart a new session, it still can't turn off the screen.

What's the problem with the forum server?

This consolekit/policykit stuff is not so easy to debug.

One theory is that because xfce4-session does not have consolekit/policykit support, the polkit daemon is not being started. However, if you start xfce4-power-manager yourself, that does start the polkit daemon, since it has that support built in now ...

My process listing for polkit:

Code:
# ps awux | grep polkit

This consolekit/policykit stuff is not so easy to debug.

One theory is that because xfce4-session does not have consolekit/policykit support, the polkit daemon is not being started. However, if you start xfce4-power-manager yourself, that does start the polkit daemon, since it has that support built in now ...

My process listing for polkit:

Code:
# ps awux | grep polkit
root      2345  0.0  0.1 141548  4428 ?        Sl   19:01   0:00 /usr/libexec/polkitd --no-debug

# ps awux | grep console

I just tried, it doesn't fix the problem.

I add consolekit and policykit as the global USE flag and update all packages with them, including xfce4-session. As you mentioned, xfce4-session wasn't compiled with the 2 USE flags last time.
To be sure, I re-emerge again xfce4-power-manager. Then I restart a new session, it still can't turn off the screen.

I run the command you showed, I got this.
Code:
peiding@Gentoo ~ $ ps awux | grep polkit
root      2084  0.0  0.1 209836  3500 ?        Sl   Sep27   0:00 /usr/libexec/polkitd --no-debug
peiding  18900  0.0  0.3 195160  6328 tty1     Sl   13:46   0:00 /usr/libexec/polkit-gnome-authentication-agent-1
peiding  19790  0.0  0.0  12192   912 pts/0    S+   13:54   0:00 grep --color=auto polkit

I have one more line.

I start X server by startx, is it the source of the problem? In my ".xinitrc", I wrote
Code:
exec ck-launch-session startxfce4
as taught in the guide.

What's the problem with the forum server?

about the consolekit

This is no longer correct. You want:

Code:
exec startxfce4 --with-ck-launch


See the updated Gentoo XFCE guide.

You need to grep "console-kit" not "consolekit" (note the hyphen). You can ensure it's enabled via

Code:
# rc-update show | grep consolekit
           consolekit |      default

Frustrating, isn't it?

I corrected the command and run again. That's the output
Code:
peiding@Gentoo ~ $ ps awux | grep console

The last easy thing to check is that you have a valid consolekit seat; my output:

Code:
# ck-list-sessions
Session1:
   unix-user = '1000'
   realname = '(null)'
   seat = 'Seat1'
   session-type = ''
   active = TRUE
   x11-display = ':0.0'
   x11-display-device = '/dev/tty7'
   display-device = ''
   remote-host-name = ''
   is-local = TRUE
   on-since = '2012-09-28T10:01:41.733670Z'
   login-session-id = '10'


The keys here are that "active" and "is-local" are "TRUE" .

If this is consistent, you might have to dig in the xfce4-power-manager code to see exactly what the failure point is ...

yes, consistent. my output is
Code:
Session1:
   unix-user = '1000'
   realname = '(null)'
   seat = 'Seat1'
   session-type = ''
   active = FALSE
   x11-display = ''
   x11-display-device = ''
   display-device = '/dev/tty1'
   remote-host-name = ''
   is-local = TRUE
   on-since = '2012-09-28T12:38:25.446302Z'
   login-session-id = '8'
   idle-since-hint = '2012-09-28T12:38:56.831787Z'
Session2:
   unix-user = '1000'
   realname = '(null)'
   seat = 'Seat1'
   session-type = ''
   active = TRUE
   x11-display = ':0'
   x11-display-device = '/dev/tty7'
   display-device = '/dev/tty1'
   remote-host-name = ''
   is-local = TRUE
   on-since = '2012-09-28T12:38:33.230567Z'
   login-session-id = '8'


Apparently, Session2 has active and is-local both TRUE. Is it possible that this issue could disappear if I use graphic login program?
