Slackware 13.37 - can start XFCE but not KDE, xorg seg faults


Hi all,

Slackware version: 13.37_x86, with latest patch applied via slackpkg
KDE version: stock 13.37

I could start XFCE but not KDE either on runlevel 3/startx or via runlevel 4/kdm.

Here is the xorg log: http://pastebin.com/bqWnH7gW

Some probably useful information in the log:

I also have the old disable composite thing:

Quote:
lysender@darkstar:~$ ls /etc/X11/xorg.conf.d
50-vboxmouse.conf disable-composite.xonf
lysender@darkstar:~$ ls /etc/X11/xorg.conf.d/disable-composite.xonf
/etc/X11/xorg.conf.d/disable-composite.xonf
lysender@darkstar:~$ cat /etc/X11/xorg.conf.d/disable-composite.xonf
Section "Extensions"
Option "Composite" "Disable"
EndSection
lysender@darkstar:~$
I have installed full stock 13.37 before without this issue but then something weird happened that I need to re-install everything (broke my xorg on current).

I install this way: day 1, installed disk 1 of 13.37 x86, day 2, installed disk 2. The day 3 which is supposed to be the KDE disk, I downloaded KDE directory from mirror instead of downloading disk 3. Then installed. After starting KDE, I experienced the error mentioned above.

Another thing I did was removed kde, then installed again via slackpkg, still the same issue as above.

By the way, I installed the freetype, cairo, fontconfig and libXft path for beautiful fonts from dugan's lcdfilter (if ever that would be related to the problem).

And lastly, this is a VM under virtualbox 4.0.8.

Thanks in advance

VirtualBox's video driver often has issues with OpenGL accelerated rendering which KDE uses a lot of. For now because you are on a VM, just stick to Xfce as it'll be lighter on system resources and faster.

Hi ReaperX7 for the input.

I open up the settings manager for KDE in XFCE and disabled desktop effects. Upon starting KDE again, it works.

Thanks
