I have installed my graphics card driver. But when I login, before the welcome screen appears and also before the login screen I see a screen with all black and white boxes. What could be the posible reason?
And does installing from nvidia from community repository fix this problem?
Thanks a lot.
Hi Nihilanth,
According to your other post, you’ve already installed the proprietary NVIDIA driver (from the Nvidia website) is this correct?
If so, you do not want to install from the Nvidia repository unless you first uninstall the proprietary drivers you are currently using.

This is a known issue with the proprietary driver. However, it does not cause any other problems. Also, the proprietary driver is better than the community one. So, I suggest you do not revert back to the community driver now.
I think that’s KDE that’s too blame, I remember reading something about it before. Normally your videocard RAM is flushed… which isn’t being done, so you’re seeing old ‘remnants’.
It showed me parts of Vista when I rebooted from Vista to openSUSE without powering off. It doesn’t do any harm though, so don’t worry about it.
If you don’t have the NVIDIA drivers installed atm, installing them will do you no good for this particular issue. I’m using the NVIDIA ‘community’ drivers and am still seeing this slightly odd behavior.
You may still wish to install the drivers for other purposes however, like hardware acceleration for video’s or fancy desktop effects.
[edit]
Going by the other comments it seems to happen only if you already have the driver installed… and I agree with syampillai, keep the situation as it is. No harm is being doing and the proprietary drivers are vastly superior.
i had the same problem
the answer?
remove kde4-kdm-branding-openSUSE and install kde4-kdm-branding-upstream instead
what do you mean with “community” driver?
you mean Not installing nvidia driver?
or installing from nvidia repository?
Nvidia drivers available at the Nvidia website are not opensource. But, they are free. Since, the drivers released by Nvidia are not opensource, it can not be packaged with openSUSE. However, openSUSE comes with an opnesource driver for Nvidia cards and that is what I referred to as community driver. Anyway, Nvidia proprietary driver is superior to the opensource driver.
I dont get what do you mean by “kde4-kdm-branding-openSUSE” and “kde4-kdm-branding-upstream”. I m a new to openSUSE and linux. So I am sorry if i ask a stupid question.
Click the application launcher (k icon or opensuse lizard icon) then go to Computer>Yast.
Once in Yast choose Software Management.
Search for kde4-kdm.
uninstall kde4-kdm-branding-openSUSE and kde4-kdm-branding-upstream will be automatically checked to install. Click accept and it will install upstream branding for kdm.
Hope this helps!
Ian
Thank you Ian for such a fast reply,
But what does it mean? I mean what is the difference between branding-openSUSE and branding-upstream? And also what do they mean.
Thank you again. 
Not really sure what the significance is. My Nvidia driven desktop is 8 years old and I rarely use it.
K Desktop Environment 4 - K Desktop Manager - Branding - openSUSE
KDE4-KDM-Branding-openSUSE
vs
K Desktop Environment 4 - K Desktop Manager - Branding - Upstream
KDE4-KDM-Branding-Upstream.
The openSUSE version is what gives that openSUSE splash screen when you boot up.
The upstream version will have a different splash screen.
These are the only noticeable difference I can think of.
Yes! Thanks! I’ve been searching for a solution to this too. Finally! Mucho gracias!
