Default black line on right side

Hi gang,
New to the forum, I tried to see an earlier post but couldn't find one. I know that this is happening to a lot of people with Toshiba laptops. After I installed the nvidia drivers on my toshiba I have about a 1/4 inch of black verticle stripe not being used. I entered this in my etc modules but didn't fix.
options nvidia NVreg_SoftEDIDs=0 NVreg_Mobile=2
If anyone has a fix or any ideas to try I would appreciate it.
Thanks,
Mike

I can't believe that I am the only one with this problem. Is there any toshiba laptop owners out there running linux?

Cool Re: black line on right side

I am also having this problem with my Toshiba Satellite Pro 6100 running Fedora Core 2. I can eliminate the blank strip by changing the driver name from "nvidia" back to "nv" in the xorg.config file. The only trade off is that I lose my GLX extension support, which means no cool OpenGL screensavers or games. Which I suppose is an ok trade off since I do not need those benefits in my corporate environment, but it would be nice to have a legitimate fix for the issue. I have installed the latest drivers, made all suggested changes in the xorg.config file per the NVIDIA Readme page, and even tried changing the Horizonal Sync Rate and Vertical Refresh Rate.

The other thing I did was remove the rivafb support that reportedly conflicts with the NVIDIA drivers.

I am running 1024 x 768 with 24bit color depth.

The issue has been discussed several times for several toshiba laptops. For some reason NVIDIA drivers for the last two years always produce the black stripes. You can try editing your XF86Config and add those two lines as options, or you can extract the driver and change os-registry.c with the values you specified and install the modified driver. This is the way I usually do it. The problem is that the 6xxx series of the driver produces strange results with these changes and becomes unusable on many toshiba laptops. This means the 5xxx series is the safest bet but the 5xxx series is not compatible with the newest kernels default configuration due to the stack size. This can be avoided by compiling the kernel correctly or using an older kernel (the change should have been made around 2.6.5, I am not sure about this). I hope this helps.

I have a Toshiba laptop with the GeForce4 420 go (16mb) and have the same problem.

The fix that seems to work is to run it at 16bit color (I run 1024x768) and put in the x config file this line under device:

Code:
Option "IgnoreEDID" "1"

I have this problem too. I am going to try the Option "IgnoreEDID" "1" fix but I am running the native resolution which is like 1400Xsomething so I hope it works. I will let you know if it does.

Sorry i din't get back to you earlier. To extract the driver run:
./NVIDIA-Linux-x86-1.0-6111-pkg1.run --extract-only
In the folder your driver is located. If you get an error saying you don't have permissions then:
chmod +777 NVIDIA-Linux-x86-1.0-6111-pkg1.run
and try again.
After you have extracted then go to /usr/src/nv in the NVIDIA-Linux-x86-1.0-6111-pkg1 folder. The file os-registry.c is located here. Open it up in your favorite text editor scroll down untill you see this and change the values as I have them below:

/*
* Option: SoftEDIDs
*
* Description:
*
* The SoftEDIDs registry key enables dynamic generation of an appropriate
* EDID for mobile LCD displays from data stored in the video BIOS. If this
* is turned off, then on mobile systems, a hardcoded EDID will be chosen
* from a table, based on the value of the Mobile registry key.
*
* Possible Values:
*
* 0 = disable dynamic EDID generation
* 1 = enable dynamic EDID generation (default)
*/

static int NVreg_SoftEDIDs = 0;
NV_MODULE_PARAMETER(NVreg_SoftEDIDs);

/*
* Option: Mobile
*
* Description:
*
* The Mobile registry key should only be needed on mobile systems if
* SoftEDIDs is disabled (see above), in which case the mobile value
* will be used to lookup the correct EDID for the mobile LCD.
*
* Possible Values:
*
* ~0 = auto detect the correct value (default)
* 1 = Dell notebooks
* 2 = non-Compal Toshiba
* 3 = all other notebooks
* 4 = Compal/Toshiba
* 5 = Gateway
*
* Make sure to specify the correct value for your notebook.
*/

static int NVreg_Mobile = 2;
NV_MODULE_PARAMETER(NVreg_Mobile);

Save and exit your text editor. Run the installer from the extracted NVIDIA folder. You need to exit X and run it as root to make it work.

Default Re: black line on right side

Hey I was wondering if matjaz's suggestion worked for anyone. Unfortunately it did not for me. I am about ready to recompile to fix my stacks and use a 5XXX series driver because those seemed to work for me but I wanted to check on this thread and see if anyone had any other suggestions first. I have researched this problem for hours and tried a billion different options in my xorg.conf, as well as in my modules.conf and nothing seems to help. Must kill the now infamous Toshiba black bar of doom!!!

I am running Fedora Core 3 final fully up2date on a Toshiba 6100 pro. If anyone can help me on this I will send them an invite for the Google mail beta (heh I know these things are a dime a dozen now but hey maybe someone with the answer out there doesn't have one yet :-)

For those people that can sacrifice bleeding edge to get their black 12x1200 right-edge pixels back, here's a solution after fighting 3 days with the 6629 drivers.
This is for a Toshiba 5105-S701 capable of 1600x1200 24 bit running Mandrake 10.1 Official, kernel 2.6.8-12mdk, GeForce4 4400Go 64 Mb.

Go to the Nvidia linux driver archive and download and isntall version 5336.

Add the following to these xorg.conf sections:

Section "Monitor"

Modeline "1600x1200" 162.00 1600 1664 1856 2160 1200 1201 1204 1250 +hsync +vsync

Section "Device"

Option "IgnoreEDID" "True"
Option "MetaModes" "1600x1200"
Option "NvAgp" "0" # Without this, X locks on glx apps
Option "MetaModes" "1600x1200"

Section "Screen"
Subsection "Display"
Depth 24
# Virtual 1600 1200 #Comment "virtual" lines if you ahve them
Modes "1600x1200"

That's it. This should work for lower resolutions as well. You can generate a modeline like the one above with

> gtf 1600 1200 60

or google around.

It's annoying not having AGP support (cuts my glxgears from 2800 to 1800 fps), but it's more annoying not having 3D accel at all or having to cope with the black strip plus a maximum of 1400x1050 16 bit and messed up fonts.

I hope NVIDIA can think a little bit more about the Toshiba users for the next driver's release
If anybody has a solution for 6629 not posted in this forum (and I tried most of the pseudo-solutions found here), I'm all eyes.

One more thing to complete the above. With this kernel and this driver version, the /dev/nvidia* and /dev/nvidiactl nodes are not recreated at boot time, though they are created while installing the driver. An easy working solution is to add to some init script e.g. /etc/rc.local, the 9 lines:

#Create the nvidia devices
mknod -m 660 /dev/nvidia0 c 195 0
mknod -m 660 /dev/nvidia1 c 195 1
mknod -m 660 /dev/nvidia2 c 195 2
mknod -m 660 /dev/nvidia3 c 195 3
mknod -m 660 /dev/nvidia4 c 195 4
mknod -m 660 /dev/nvidia5 c 195 5
mknod -m 660 /dev/nvidia6 c 195 6
mknod -m 660 /dev/nvidia7 c 195 7

mknod -m 660 /dev/nvidiactl c 195 255

Working nicely now

I had to revert back to the patched 4363 driver availabe from www.minion.de.
The harderst part for me was the fact that I am running ubuntu and one of their 2.6.8.1-4 kernels. So for those of you running Linux on the Toshiba Satellite Pro 6100, I had to do this:
Download the patched driver from www.minion.de and run that.
I then had to add the following script to /etc/init.d:

#Create NVidia Devices
mknod -m 660 /dev/nvidia0 c 195 0
mknod -m 660 /dev/nvidia1 c 195 1
mknod -m 660 /dev/nvidia2 c 195 2
mknod -m 660 /dev/nvidia3 c 195 3
mknod -m 660 /dev/nvidia4 c 195 4
mknod -m 660 /dev/nvidia5 c 195 5
mknod -m 660 /dev/nvidia6 c 195 6
mknod -m 660 /dev/nvidia7 c 195 7

mknod -m 660 /dev/nvidiactl c 195 255

chgrp video /dev/nvidia*

Which is pretty much what the above posts all say, except that I had to do a chgrp on the /dev/nvidia* files so that the gl stuff would run once X started.

The reason i had to go back to the 4363 driver was that the switching down to a console from X produced a garbled screen. Otherwise, the 5336 driver worked fine as well.

I could not get the resolution beyond 1400x1050 nor could I get any of the 6series drivers to work without getting the split window.
