Login screen has wrong aspect ratio in Mageia 2

[mailedfist]

I have recently upgraded to Mageia 2 - a nice painless process using the on-line distro upgrade. Excellent!

However, I have been left with one quirk. The login screen seems to be set up for 16:9 ratio screens, so it doesn't look very good on my 4:3. Is there an option to change it?

[doktor5000]

Which login manager are you using?

[mailedfist]

KDM.

There's something else odd going on I've now found - if I try to open "Login Screen" in the "System Administration" section of "System Settings", it doesn't do anything.

[doktor5000]

Can you please try via Alt+F2 and there you enter kdesu systemsettings

[mailedfist]

I get the same behaviour. If I do so in konsole instead, I get

Code: Select all

[mark@fast ~]$ kdesu systemsettings
"KConfigIni: In file /usr/share/locale/currency/gbp.desktop, line 1: " Invalid entry (missing '=')
"KConfigIni: In file /usr/share/locale/currency/gbp.desktop, line 3: " Invalid entry (missing '=')
"KConfigIni: In file /usr/share/locale/currency/gbp.desktop, line 4: " Invalid entry (missing '=')
[mark@fast ~]$


The errors appear before I get the prompt for the root password, so are probably irrelevant, but I thought I should include them.

[mailedfist]

In the "System Administration" section, all options work except for "Login Screen" and "Date & Time", which both just cause the application to exit.

Is there a general location which KDE logs errors too? There's nothing significant in /var/log/messages.

[mailedfist]

Ignore the last message please.

Running "systemsettings" direct in konsole, I get:

Code: Select all

ystemsettings
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.

[mark@fast ~]$ systemsettings: symbol lookup error: /usr/lib/libpolkit-gobject-1.so.0: undefined symbol: g_dbus_error_register_error_domain

The last line appears at the point of the exit, so I suspect is the error. However, is it due to the QDBusConnection warning?

[doktor5000]

The last line doesn't look good. How did you do your upgrade to Mageia 2, which mirror did you use, and did you check if all packages have been updated?
Please show the output of

Code: Select all

urpmq --list-media active

and also try an

Code: Select all

urpmi --auto-update

to see if everything has been updated. Please post the output of that, too.

[mailedfist]

I got notified that Mageia 2 was available by the update widget, and let it go ahead and upgrade. I don't remember picking a mirror (but, then again, my memory's not very good!).

I added the extra repositories after upgrade and before reboot because of concerns over graphics drivers.

I have now realised that the update widget is not just hidden but missing from my tool tray.

[mailedfist]

That said, if I go to Mageia Control Center and ask it to update, it says there are no updates needed. That's a bit odd, given the above urpmi output, isn't it?

[mailedfist]

Appears from a web search that the missing function should be in /usr/lib/libgio-2.0.so.0, which is a symlnk.

Now, we have:

Code: Select all

   0 lrwxrwxrwx 1 root root      32 May 26 10:12 /usr/lib/libgio-2.0.so -> ../../lib/libgio-2.0.so.0.3200.1*


Code: Select all

1368 -rwxr-xr-x 1 root root 1393448 Apr 25 08:41 ../../lib/libgio-2.0.so.0.3200.1*


Which looks OK. However,

Code: Select all

   0 lrwxrwxrwx 1 root root      22 Oct 16  2010 /usr/lib/libgio-2.0.so.0 -> libgio-2.0.so.0.2400.1*
 708 -rwxr-xr-x 1 root root  720200 May  4  2010 /usr/lib/libgio-2.0.so.0.2400.1*
 

does not look so good. Should the .0 symlink have been updated and hasn't been?

[doktor5000]

Can you please give the output of

Code: Select all

rpm -qf /usr/lib/libgio-2.0.so.0.2400.1

and

Code: Select all

rpm -qf /usr/lib/libgio-2.0.so.0.3200.1

For your other question, the Mageia control center and the update applet only consider repositorier which are marked as update repos.
And as there are no updates available yet for Mageia 2, there won't be any shwon there. urpmi considers all enabled repositories, that's the difference.

Note: Mageia 1 was installed as an upgrade from Mandriva 2010. Is it possible that the problem I'm now getting having upgraded to Mageia 2 is down to something which went wrong at that point?

Could be possible, yes.
Can you please try

Code: Select all

urpmi --replacepkgs libgio2.0_0-2.32.1-2.mga2

[mailedfist]

Sadly, that made no difference.

As I have now got another annoying quirk, which may or may not be related, in that open konsole windows are not appearing in the task bar, I want to make some progress on this, so I have just done the following:

Code: Select all

[root@fast mark]# cd /usr/lib
[root@fast lib]# mv libgio-2.0.so.0 libgio-2.0.so.0.old
[root@fast lib]# ln -s ../../lib/libgio-2.0.so.0 libgio-2.0.so.0


systemsettings now does not crash. However, I can't find an option to tell the theme to use 4:3 ratio.

[mailedfist]

OK. Something is definitely wrong in Mageia 2.

To get systemsettings to work, we need the "3200" version of libgio symlinked. However, that breaks K3b, which needs the link to the "2400" version put back.

Dependency tracking has gone awry somewhere by the look of it.

[doktor5000]

Well, no, it's just that your old version of that file is not owned by any package (and hence it's the problem)

Code: Select all

[root@fast mark]# rpm -qf /usr/lib/libgio-2.0.so.0.2400.1
file /usr/lib/libgio-2.0.so.0.2400.1 is not owned by any package

Please also show the output of

Code: Select all

rpm -qi k3b

[mailedfist]

But surely the fact that the mga2 k3b needs the old libgio means something has gone wrong?

Code: Select all

K3b is CD-writing software which intends to be feature-rich and
provide an easily usable interface. Features include burning
audio CDs from .WAV and .MP3 audio files, configuring external
programs and configuring devices.

or am I jumping to conclusions and it could be that k3b is using another library which is itself the wrong version and it is making the call which needs the old libgio?

[doktor5000]

Why do you think that k3b needs the old version, can you please show any output that shows this?

[mailedfist]

Setup when k3b works:

Code: Select all

[root@fast lib]# ls -als libgio*
3588 -rw-r--r-- 1 root root 3666220 May  4  2010 libgio-2.0.a

1168 -rwxr-xr-x 1 root root 1188852 Apr 10 18:43 libgiomm-2.4.so.1.3.0*

Move to "new" libgio, which makes systemsettings work:

Code: Select all

[root@fast lib]# mv libgio-2.0.so.0 libgio-2.0.so.0.old
[root@fast lib]# mv libgio-2.0.so.new libgio-2.0.so.0
[root@fast lib]# mv libgio-2.0.so.0.new libgio-2.0.so.0


Now run k3b:

Code: Select all

[mark@fast ~]$ k3b
k3b: symbol lookup error: /usr/lib/libgio-2.0.so.0: undefined symbol: g_signal_accumulator_first_wins

Revert to "old" setup and k3b works again but systemsettings doesn't.

[mailedfist]

Putting aside the issues with systemsettings etc, for the momenty, the headline issue seems to be related to ATI graphics cards.

I now have several machines which don't exhibit the problem and have other vendor's graphics cards. I have three machines with ATI cards, of wildly differing ages, which all exhibit the login screen aspect ratio issue. I'll try and dig a bit deeper when I have time.
