8756 black bar toshiba satellite 420 go

[ewiget]

O.k., so I have been running linux on this laptop for many years. And there was always the blackbar issue unless you had Option "IgnoreEDID" "true" in your config file....but now this doesnt seem to work.

Some of you may remember me from the post I had with issues with the previous module on gentoo.....but now I am running on xandros beta 4. I had 8178 running just fine using the hack required for 2.6.15 series kernels.

Here is my current config (which has the black bar irregardless of whether I use the IgnoreEDID option:

/etc/modprobe.d/nvidia file

options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1 NVreg_SoftEDIDs=0 NVreg_Mobile=1 NVreg_DeviceFileUID=0 NVreg_DeviceFileGID=44 NVreg_DeviceFileMode=0660

Have you tried any of the new xorg.conf options:

Option "UseEdidFreqs" "boolean"
Option "UseEDID" "boolean"

There appears to be a lot more new options affecting the use of EDID info in this driver, have you taken a look at the README recently?

sure haven't, although I did try the NVreg_Mobile=4 as recommended in another toshiba thread right now.

I will take a look at the readme and update when I find a fix.

I commented out the Option "IgnoreEDID" "true" part since it was deprecated and ignored:

If I set both UseEdidFreqs and UseEDID to false (since they are true by default), then the black bar grows to about 3 inches on the right of the screen, and there is a gray bar about 1/3 of the way up the screen and about 1/4" wide that runs horizontal.

If I comment out UseEdidFreqs which makes it true by default and leave UseEDID as false, then I get a 3 inch black verticle bar on right, and a 1/2" horizontal bar about 4 inches up the screen that gradually gorws brighter in color from gray to white....but no kdm or gdm appears.

If I have UseEdidFreqs false and comment out UseEDID which makes it true, then I have the same original problem - about a 1 inch black bar on the right of the screen that runs verticle, however, I have the kdm login screen and adding the virtual screen allows me to scroll hard right or hard left to view the screen.

Both of these options were using the same nvidia modules as above, except I tried mobile=5 for this test (per someone else post in another toshiba thread)

interesting ... 1 inch that's a lot ... mine is no more than 3-4 mm but I'm a
perfectionist so it bothers me .
When launching startx with logverbose 6, I get:

1) if UseEdid = True
with

Option          "ModeValidation" "NoMaxPClkCheck,NoEdidMaxPClkCheck,NoMaxSizeCheck,NoEdidDFPMaxSizeCheck"

Mode is rejected: Mode (1600 x 1200) is too large for DFP

because the EDID infos are:

(--) NVIDIA(0): --- EDID for NVIDIA Default Flat Panel (DFP-0) ---
(--) NVIDIA(0): EDID Version                 : 1.3
(--) NVIDIA(0): Manufacturer                 : NVD

(--) NVIDIA(0): Valid VRefresh Range         : 0Hz - 60Hz
(--) NVIDIA(0): 
(--) NVIDIA(0): Detailed Timings:

(--) NVIDIA(0):     HRes, HSyncStart : 1588, 1664
(--) NVIDIA(0):     HSyncEnd, HTotal : 1856, 2160
(--) NVIDIA(0):     VRes, VSyncStart : 1200, 1201
(--) NVIDIA(0):     VSyncEnd, VTotal : 1204, 1250
(--) NVIDIA(0):     H/V Polarity     : +/+

It's unlogical as it should be possible to get the following valid modeline
too
ModeLine "1600x1200_60_0" 161.89 1600 1672 2032 2176 1200 1202 1214 1240
which is 1600x1200, below 162 MHz dotclock ...

2) if UseEdid = False (whether UseEdidFreqs = True or False):

(II) NVIDIA(0):   Validating Mode "1600x1200_60_0":
(II) NVIDIA(0):     1600 x 1200 @ 60Hz

(II) NVIDIA(0):       H/V Polarity     : -/-
(II) NVIDIA(0):     Mode is valid.
(II) NVIDIA(0): 
(WW) NVIDIA(0): Unable to use mode "1600x1200_60_0" for DFP-0; cannot compute
(WW) NVIDIA(0):     backend DFP timings (no EDID).
