When I initially tried to boot from a live-cd, the screen turned black and I had to restart the computer. When I chose 'Basic Video' instead of normal booting, it worked fine.
I also used the 'Basic Video' mode when I installed to harddrive.

Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information especially concerning your hardware we require that will be helpful in our diagnosis of this issue.

Could you try to start once more (WITHOUT basic video driver) and follow the following instructions, please?

If the anaconda crashes during the switching to the graphic mode, most likely the problem lies in Xorg support for your graphics chip. There are couple of options how we can obtain information necessary for resolving the issue.

If the computer is not completely frozen when installation fails, switch to the console (Ctrl+Alt+F2) and copy /tmp/X* and /var/log/anaconda.xlog to some other place -- USB stick, some other computer via network, somewhere on the Internet, and please attach it to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.

If the computer is completely useless after installation fails, you can also install Fedora with a VESA mode driver (see http://docs.fedoraproject.org/en-US/Fedora/13/html/Installation_Guide/
for more information on that). Then after successful installation you can collect /var/log/anaconda.xlog, /var/log/Xorg.0.log, and the output of the program dmesg instead.

Or you can install Fedora in a text mode completely, and then start X after that. If it fails, still /var/log/Xorg.0.log and the output of dmesg program from the failed attempt to start X would be useful.

We will review this issue again once you've had a chance to attach this information.

Thank you very much in advance.

I've already installed with the VESA mode driver as you suggest.
After the installation I temporarily moved the xorg.conf and then restarted the computer. When the screen turned black, I switched to Ctrl+Alt+F2 and copied /var/log/Xorg.0.log. That is the Xorg.0.log I've already attached.

I'm sorry if that was unclear in my initial description. I will upload the rest of the files as soon as I have time to try it.

Comment 4 Ulrika Uddeborg 2011-03-20 19:33:13 UTC
I've discovered that it gives different results if I connect the monitor with a VGA-BNC cable or a VGA-VGA cable. I initially used the VGA-BNC cable and it was then that the screen turned black. However, with a VGA-VGA cable I get a picture on the screen.

Without an xorg.conf file I only get low resolution. With some assistance I managed to make an xorg.conf file using "Xorg -configure". I added a monitor section in it, where I specified the properties of my monitor. I also used the "gtf" command to create a modeline.

When I boot with nomodeset and my xorg.conf the computer manages to detect several other modelines, apart from the one I created. When I, on the other hand, boot without nomodeset and my xorg.conf the computer doesn't detect any more resolutions apart from the low ones and the one I added.

I tried to use another monitor and it worked fine. I'm not planning on keeping the old monitor (Philips Brilliance 21B) and I was wondering if you want me to test anything else or if I can throw it away?

No we don't expect to work properly with bnc connector
