From the nvidia-drivers documentation:
Quote:
A "display device" refers to some piece of hardware capable of displaying an image. There are three categories of display devices: analog displays (i.e., CRTs), digital displays (i.e., digital flat panels (DFPs)), and televisions. Note that analog flat panels are considered the same as analog CRTs by the NVIDIA Linux driver.
So the CRT reference seems to be a red herring.

I can say that this problem is WM independent (I get the exactly same effect when running TWM). I don't recall seeing the same effect when running Windows 2007. Unfortunately I can't test this atm because I took too much hard drive space for Linux. (The Windows partition manager happily shrunk the C drive to 90GB without complaining and now I can't run W2007. If I get this problem fixed then I might reclaim the C drive as a spare partition for Linux).

When I get this fixed, I will use "slim" as a login manager (XDM only reads the global xinitrc file). In the mean time, I still boot up into runlevel 3. At least this way, I can rapidly test changes to the X configuration I make.

I have a spare monitor that I can try out but (unless I can find the right change to make) I am beginning to suspect a bug in the nvidia driver.

With EDID disabled, you have to specify your own horizontal and vertical sync, and resolutions. So you have to add these thing to xorg.conf.

If you decide to try and use the nouveau driver again with your video card install all the packages from testing, without an xorg.conf file. I have the same video card on my emachine.

xorg.conf was generated when I ran nvidia-xconfig and has all of the necessary parameters in it already. I dare not tweak anything in the file (unless I know exactly what I am doing). At best startx won't work and at worst I could cause damage to my hardware.

I really appreciate the time you are spending assisting me with this problem. This is proving to be a tough nut to crack and if you get fed-up trying then I understand. OTOH I hope you haven't run out of ideas yet.

Of course! That #@&^^%!!! 2.6.37.6 kernel was part of the problem! I had recently upgraded two oldish laptops to 13.37 and neither would run properly with the 2.7.37.6 kernel.

Now that I have upgraded to the 2.6.38.4 kernel, noveau works almost the way it should. The on-screen fonts (and those in Terminal) are bigger but I don't mind looking at the screen without my nerd-glasses.

The only problem is that the entire screen is shifted to the right and xvidtune refuses to do anything about it. Is there any other way to adjust this?

PS: nvidia gives the identical screen problem whether the kernel is 37 or 38 and whether I am using the generic or huge kernel.

Check the monitor manual and see if the horizontal and vertical sync values are the same as in xorg.conf.

*sob* If only such information was out in the public domain! The only documentation I can find on the E192HQV is the "user" manual which assumes that only window$ is being used. There is not a single useable number in the whole book!

Surprisingly enough, I managed to get the screen positioned correctly! (All I had to do was press the "auto" button on the monitor *blush* ). There is still a slight overshoot to the right when I use the noveau driver (probably because noveau incorrectly detects the resolution to be 1366x768 instead of 1368x768) but using the nvidia driver, everything fits perfectly now.

I will now mark this thread as solved. It isn't really though. There are still vertical strips of slight "fuzziness" when I use nvidia but I think I will have to live with that until we get a linux-based E192HQV driver.

Thank you very much for your help H_TeXMeX_H. Even if I haven't found a perfectly satisfactory solution, my knowledge of screens and drivers has improved dramatically.

I'm not certain what is ausing the 'fuzziness', it could be refesh rates are out, just a cheap screen or something else I havent considered. But you shouldnt need a driver for ther E192HQV (or other monitors without add-in hardware for that matter). What you want is decent EDID.

Thanks for finding that. I don't know if it is helpful or not. According to the manual, the frequencies are 47.712 x 59.790 and according to the Xorg.0.log (when I am running noveau) the frequencies are 47.7 x 59.8 which may just be rounded off numbers.

When running nvidia, neither the Xorg.0.log nor the xorg.conf file refers to the frequencies used.

If I could generate a decent xorg.conf for the noveau driver I might be able to tweak the modeline. However, I have a lot of homework to do before I attempt something like that.

You should be able to just modify the xorg.conf to put in whatever info you want.

xorg.conf was generated by nvidia-xconfig. I need a noveau-generated xorg.conf that I can touch up.

xorgsetup should create an xorg.conf.
