When the freshly-installed nvidia driver loads on boot-up, I get a blank screen in konsole mode in SuSE 9.1. Occasionally I see some characters on the konsole screen, but they are much larger than they should be, and disappear soon.
X is OK, the problem only concerns the konsole.

Could you help me how to troubleshoot this problem?

You know people are becoming too dependent on the GUI when they call it 'konsole' mode.

I suggest downgrading and waiting until a new one comes out. Often new nvidia driver cause problems that are fixed in the next release. You can use a livecd to stop the nvidia module loading on boot.

It could be your framebuffer. Assuming you're using lilo, edit /etc/lilo.conf and replace the "vga=" parameter with a lower resolution setting. In other words, something like "vga=791" is 1024x768 with a 64K color depth, which may be too high for some monitors. Choose a really low resolution, such as "vga=771" (800x600 with 256 colors) or just the plain "vga=normal".

To be honest, I wouldn't worry too much about it. Booting up should only take a minute or so, and as long as X works you should be in good shape -- J.W.

I don't think you two understand his problem.

After he installed his nVidia drivers, and opens the "konsole" program, the konsole screen is blank. It's not that he's "dependent on a GUI," and therefore refers to the command line as "konsole mode."

I have the same problem as well, and am working to fix it right now. If anyone has figured this out, any help would be appreciated.

the Nvidia drivers have issues with the framebuffer drivers, using vga=normal would work for sure if that is the problem.

I'm using grub, not lilo. I probably should have mentioned that.

However, I don't know what that has to do with the fact that the konsole program results in only a blank screen.

I can do a normal console (with a "c," not a "k") login and I have no problems with blank screens. It's the KDE program "konsole" that has a blank screen.

"vga=normal" helped. Thanks for the tip!

To Ringfinger:
That option (kernel parameter) works for grub, too, only you will not enter that option into /etc/lilo.conf, but into /boot/grub/menu.lst.

By the way, I have a movix2 system, too, where the problem is just the opposite: X comes up with a blank screen (with a green bar to the left, only), and I have to change to a text konsole and back to X in order to get the correct X screen with the movix logo.
"vga=normal" did not solve this latter problem.
Is there an other workaround?

Is there any particular place in menu.lst I have to put that option? My problem persists even after doing that.
