X can't connect to my monitor

I have a problem with my X server.
Everytime I start it, the first time everything works fine, but if I need to switch from X to a terminal, or just need to restart it, my monitor shows the error message "no signal found" and keeps showing it until I restart my computer.
It only shows up the second time I want to switch to X, start it, or want to switch from X to a terminal, the first time it's alway working well. If this problem occurs I can't even restart my pc with ctrg+alt+del and need to do in manualy.

My xorg.conf:

Re: X can't connect to my monitor

Does it happen if you use the nv driver instead of nvidia ?  I had a similar issue with Slackware and using nv "fixed" it.  Eventually the issue stopped with updated drivers from NVidia.  Not sure exactly when, but I hadn't changed anything else.

Re: X can't connect to my monitor

Thanks, you really helped me out. I switched from nvidia to vesa and now it seems to work.
I recompiled my nvidia package to see if the error could be fixed that way, but it didn't work out, so I guess I'll just have to sick to vesa for now, and wait for a new version of the driver.

Re: X can't connect to my monitor

Glad you got it narrowed down. 
Since you can be reasonably sure it is related to the NVidia drivers, maybe someone on one of the NVidia Linux forums has a better solution, given your combination of hardware, kernel and driver version.  I'd definitely try posting one one of them.

Re: X can't connect to my monitor

I have the same problem as blue-dev, except using an ATI X1600 and a Samsung SyncMaster 2253BW (DVI). I want to use DVI but I couldn't get it to work on arch so I gave ubuntu a try. The latest ati driver from ati.com works great in ubuntu. No issues when closing X or switching to a terminal. I tried using the same xorg.conf as I do in ubuntu in arch, same graphics driver, still doesn't work. I also tried the catalyst package in arch. Only difference is that ubuntu is 64bit and arch 32bit. (will install 64bit soon) Could the 32bit driver be the problem?

Here's the working xorg.conf I use in ubuntu:
