           Summary: another KDE4 + nVidia (270) bug
           Product: kde
           Version: 4.6
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: corneld_linux at yahoo.com


Version:           4.6 (using KDE 4.6.0) 
OS:                Linux

Yesterday, after upgrading my OpenSuse 11.4 system to the waiting-to-install
upgrade packages, amongst which there where the kernel 2.6.37.6 and the new
nVidia driver v.270
After the necesary restart (due to the new kernel installed) I could not have a
normal work session with KDE4.
This is, though, a very strange situation: KDE seems to start OK (at least it
gives me that sound event at KDE's starting up).
But the splash screen doesn't dissapear from the screen, it remains on my
monitor, with that progress bar at about 90-95%
Even stranger, and frustrating is the fact that the KDE seems to be working OK,
except it doesn't shows me the normal desktop, but that darn splash-screen.
I tried to launch some applications through ALT-F2 : I blindly wrote kcalc, and
after that repeated to launch krename ... and they launch up OK, since I
checked at the console login and they are launched in the memory. This really
is very frustrating.

The only workaround was: to UNINSTALL the nvidia packages, reboot the system,
login to KDE, getting into "Personal settings" and un-check DESKTOP EFFECTS,
and then install again the nvidia packages, reboot again and now ... I can
login again normally.

So ... it seems that this new driver from nVidia is another part of the nVidia
driver hell, and not anymore compatible with 3D desktop effects.

Does anyone know  anything else on this ? I could live OK without those 3D
effects, but still ... I can't stand this line of behaviour from nVidia (v.260
worked OK, and now v.270 doesn't ! -- and this comes just after another hell in
those last days of Opensuse 11.3, with the same v.260 .. see bug #251719)


By the way, with the same driver, I could login as expected into Gnome, XFCE !


Reproducible: Always

Steps to Reproduce:
install the new nvidia v.270 driver from OpenSuse repository (or upgrade to
this version from the existing v.260 driver)

Actual Results:  
after the install + reboot, you can no longer normally login and work with
KDE4, if the desktop effects are "active"

Expected Results:  
you should login and work as normal

Gnome (2.9) and XFCE are not affected by this problem
