Stuck in low res after Nvidia driver install (Ubuntu 10.10)

[anthonyvo]

Running Ubuntu 10.10
Card is an Nvidia Quadro FX 1500
Monitor is a Dell E172FP

Well, after installing the drivers for my Nvidia Quadro FX 1500, I am stuck in 800x600. The options in the Nvidia X-server Settings (under System > Administration) show only "Auto / 640x480 / 320x240"

I've edited the xorg.conf (backed up before every attempt, of course,) to add modes, etc. but to no avail.

I just installed read-edid via Synaptic and in Terminal ran this:

$ sudo get-edid | sudo parse-edid

I received this back (apparently, no EDID is being read - I have my monitor connected with an DVI adaptor)

    Performing real mode VBE call
    Interrupt 0x10 ax=0x4f00 bx=0x0 cx=0x0

The EDID data should not be trusted as the VBE call failed

Any ideas on how to force or fake the EDID info? (I only need 1024x768 on this living room PC.)

Just bumping this up.

I've since uninstalled the manual .run driver/package from Nvidia and have reinstalled the nvidia drivers via ubuntu. Still only gives me the 640x480 resolution as the max option (but looks like it's in "auto" w/ 800x600.)

Celebration! I'm posting what worked for me in case anyone else can benefit from it:

I edited my xorg.conf (after backing it up, of course) and changed this:

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "Unknown"
    HorizSync       28.0 - 33.0
    VertRefresh     43.0 - 72.0
    Option         "DPMS"
EndSection

to this:

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "Unknown"
    HorizSync       28.0 - 72.0
    VertRefresh     43.0 - 60.0
EndSection

Now I have my Nvidia Quadro FX 1500 in 1024x768 "glory."

Congratulations! Did disabling the "DPMS"-option make it work or is just setting the correct specs enough, in your case?

For anyone else who wants to set the correct specs of the used monitor:

sudo apt-get install hwinfo
sudo hwinfo --monitor

I'm getting the same problem. I got the latest NVIDIA driver through Synaptic and still have the LowRes issue.

I have an NVIDIA FX5700 card, could someone please suggest what setting in xorg.conf I need?

[BicyclerBoy]

Any clues in the /var/log/Xorg.0.log file ?

Any EDID warnings errors..

What is the native res of the monitor ?
And connected how ?

Below xorg.conf snippet could be useful. You need to replace the "CRT-0" with something appropriate.

Section "Screen"
Identifier "Screen1"
Device "Device1"
Monitor "Monitor1"
DefaultDepth 24
Option "ModeValidation" "AllowInterlacedModes"
Option "UseEDID" "FALSE"
Option "UseDisplayDevice" "CRT-0"
SubSection "Display"
Depth 24
# Modes "1920x1080i60" "1280x720p60" "1024x576p50" "848x480p60"
EndSubSection
EndSection


The "AllowInterlaceModes" is most likely not necessary for you..


Does that read-EDID package actually work for anyone ?
I think it is i386 or powerPC only...

Did you try anthonyvo's solution, with your own monitor specs of course?

I think it had to do with the sync. I can't see how enabling Energy Star functions would have helped (isn't that what DPMS is?) The monitor seems to go to sleep after some time anyway.

Later today, I'll experiment with it and find out.

Exactly, it's about power management. But apparently it is able to interfere sometimes however. Looking forward to get your test result, thanks.

[anthonyvo]

Well, you were right. After adding the DPMS option, it would hang at the splash screen on boot. I was under the impression that the sync range was the solution. Perhaps it's a combo of the two. I might be tempted to play with the sync range to see if it too caused it... Or just leave well enough alone.
