Hi all, any help out there?? First some details; I have 64-bit Ubuntu 11.10 installed from a LiveCD and am having problems getting the resolution I know the hardware is capable of. GFX card: $ lspci grep VGA 01:00.0 VGA compatible controller: nVidia Corporation GF110 [GeForce GTX 580] (rev a1) My monitor is an LG Flatron W2243S, which unfortunately doesn't seem to have a Linux driver. I know it supports up to 1920x1080, but via the 'Displays.'

We would like to show you a description here but the site won’t allow us. Tipovoj proekt stanciya lechebnogo gazosnabzheniya.

GUI I can only select 1024x768. Yet more information! Strangely I had to hack my way into Ubuntu via 'nomodeset' - I suspect this is to do with an nVidia driver problem, and since then I've installed the nVidia driver. OK, so progress.

The LG monitor features a super energy saving mode that adjusts the brightness to a lower, more comfortable level while saving your business money in energy.

Seems the NVIDIA driver doesn't get the EDID info. From /var/log/Xorg.0.log: [ 6.757] (WW) NVIDIA(GPU-0): The EDID read for display device CRT-0 is invalid: [ 6.757] (WW) NVIDIA(GPU-0): unrecognized EDID Header.

Welcome to the forums. It looks that your display has a corrupt EDID. Since I was 'blessed' with a laptop with a similar problem, I've learned a few tricks that can help you. I can't promise you that they will work, but I would gladly help you as much as I can. My first idea would be to try to use another input. Sometimes there are more chances of retrieving the EDID data from a DVI, or HDMI input. Check this as a point of reference.

If that don't work, we need to get the correct EDID data. There is a reasonable chance that other people had faced the same problem, and may be you can find in the web a downloadable fixed EDID file that we can 'hardcode' into xorg.conf The last resort would be to try to fix it ourselves. I would gladly help you with that if it comes to it. This is an example of the work the would need to be done:. I hope those references point you in the right direction, and tell us if you need more help with this.

Thanks Papibe! I think you hit the nail on the head, but unfortunately I'm not at a solution just yet. In fact, I was looking at the possible effects of different inputs - this monitor ships with an SVGA output, which I'm having to use an adaptor to plug into the DVI port. Short of buying a new monitor, I'm not going to be able to switch that.

So, I spotted your useful tip on (dare I say it) using my Windows OS to get hold of the EDID file. Phoenix EDID Designer, installed and used.

Interestingly there are two EDIDs on there: IV46BA is an Iiyama EDID.

HSD899A appears to be just a generic one, but also no fail on CRC.
