wrong resolution in X
I cannot get this resolution working: 2048x1152 on slackware 12.2.
card: nvidia 8600GT monitor: samsung 2343nw So i tried re-installing nvidia drivers, didn't work, tried re-installing X, didn't work either, then i didn't even knew what to do, so decided to install ubuntu and see if it works there, after installation i installed the same card drivers and i had the same problem on ubuntu as well. So installed slack again and i had the same problem as well. I tried Code:
nvidia-settings Then i tried nvidia-xconfig to re-create the xorg.conf file and it didn't work as well and of course i tried editing xorg.conf by hand but it doesn't do anything either :| this is my xorg.conf pastebin as you can i see i added my wanted resolution 2048x1152, but it just ignores it or something like that. :| then i went through the Xorg.0.log and saw this: Code:
(WW) NVIDIA(GPU-0): Unable to read EDID for display device CRT-0 and also this Code:
(WW) NVIDIA(0): No valid modes for "2048x1152"; removing. Xorg log I tried googling about edid but found info for only mostly ubuntu, tried re-generating edid with some Phoenix app but it said Invalid EDID. i have no idea what to do now, can anyone help me ? :( |
If the monitor and card support the resolution at the refresh rate, then you may need to generate a full modeline for it.
You certainly need a proper monitor and device section - currently missing. You've edited xorg.conf by hand before, but I don't know what you did so cannot comment. |

Right - you need full monitor and device entries.
You may need a full modeline. Presumably you are running Ubuntu 9.04 now? Have you installed the proprietary driver? If yes - skip. If no then ........... system > administration > hardware drivers Have you installed the nvidia settings tool? If yes then skip, if no then ........... sudo apt-get install nvidia-settings sudo nvidia-settings Try to adjust the settings there. (Lets rule out this method for ubuntu before fiddling with xorg.conf manually.) Note: if the nvidia conf is restricting resolution, then double-check that the card supports the resolution and at what refresh rates and color depths. I have: Code:
Section "Device" |

Yes, i am running Slackware 12.2.
|
Code:
(WW) NVIDIA(GPU-0): Unable to read EDID for display device CRT-0 In any case you may need to tell the nvidia drivers to not use the EDID data. Option "UseEDID" "False" In your screen section, but as started you will have to add complete modelines. |
Thanks!
Option "UseEDID" "False" worked like a dream =D |

after last restart it got back to using lame resolution again. So i used nvidia-xconfig remade the config and im using 1400x1050 now, but not 2048x1152 ;-/ How do i make "proper" modelines? or any other ideas what might be wrong? |
