Right..
This is what I think.
X or xorg.conf needs the Hsync and Refresh rates in the xorg.conf as well as the modes line.
livna flattened my xorg.conf and the problem came back. Clearly either the Nvidia driver does not report back the right monitor display information or the current version of X is not setting the correct modes (For some monitors at least). There is some talk in other forums that the current release of X is less than perfect and that retro fitting X is the best solution.

At this point the problem is paling into insignificance as my current install is now rapidly going from wounded to terminal so i'm going back to Fedora 8 this week.

Best of Luck with this problem.

Hi,

I am a new Fedora user, and have exactly the same problem after installing the nvidia driver from livna: blank screen with a thin blue line on top. Any solution?

My graphics card is an on board nvidia 6100 chip. I have PCLinuxOS and Mythbuntu 7.10 on another hard disk in the same computer, and they are working fine.

If I do not install the driver, there is display, but with only max 800x600 resolution. Is there a way to "force" it to higher resolution without the driver installation?

Appreciate any suggestion. Thanks in advance.

Edit note: My Fedora installation is fresh installation with all latest updates. No additional software and changes to config except hooking up to the livna repository and install nvidia driver.


Regards

I would assume its the same problem as with the blue line.
HorizSync and VertRefresh need to be added to your xorg.conf (Check your monitor specification details).
Also add Modes "1280x960" "1152x864" "1024x768" "832x624" "800x600" "720x400" "640x480" "640x400" "640x350"
to the screen section.

I do remember the Flash Gordon effect's from early days of setting up X and it was always these that caused problems.
I was a former Ubuntu user and I know that 7.10 worked fine again the assumption is that fedora 9 and Ubuntu 8.04 are using the same X version. The problem is fairly rare I have work colleagues who have installed Ubuntu with no display problems.

Which by any stretch of the imagination cannot be right

Ok the attachment did not attach.....
Get back to you later..
I can however say Xorg -configure created a section for every Nforce device display adapter or not
in the xorg.conf.new (USB, Disk controller Ect..).

No: F9 is using the very latest (still pre-release and unfinished, "beta"-ish) X11R7.4/Xorg-1.5 (actually: 1.4.99*+), while Ubuntu 8.04 uses X11R7.3/Xorg-1.4. For further comparison, F8 uses X11R7.2/Xorg-1.3. This does not mean that a similar regression/glitch with the software is not involved - after all, they're all still "Xorg". But in general, The X11/Xorg stuff in F9 is sufficiently different from prior releases to void such assumptions. Add into the mix the proprietary NVidia driver, which incorporates some non-standard features, and which was somewhat hastily patched/updated (under extremely vocal pressure) to work with that newest X11/Xorg stuff in F9. Finally, this appears to be a somewhat rare/isolated problem.

Unfortunately, therefore, there are a very large number of possible causes for this problem, but so far, it seems that none of the usual fixes work. I wish that I could offer more concrete suggestions, but depending on how important this is to you to solve, it seems to me that only a very thorough, methodical troubleshooting exercise is necessary. Either that, or just plain luck at stumbling across the right techno-magical formula that works.

There are some troubleshooting guides available, and some other ideas have already been offered, if you wish to try them.

Good Luck,
V

I stand corrected.
I wonder if it makes a difference if this happens to users on intergrated graphics over say PCI or AGP expansion cards?
Im on intergrated graphics (It was cheap).

Theoretically of course, it should not matter much. To the best of my understanding, the biggest difference between integrated graphics (possibly using shared system RAM) and PCI/AGP cards is available VRAM. But X11/Xorg has a slightly less than spectacular history at auto-configuring all the various hardwares. I believe I already mentioned that Xorg will default to the highest resolution supported by the monitor (unlike some other OSs), even if the result is a failed GUI due to insufficient VRAM. /var/log/Xorg.0.log would show that happening.

My monitor supports up to 1600x1200. Integrated GeForce 6150 LE (with separate 256 MB VRAM). I consider this to be fairly good specs, but I've never even attempted 1600x1200 - I'm sure I could do it, but performance would plummet - or worse. So, I enforce a limit of 1200x960 @ 24[32] bpp color depth, which I personally find to be an adequate balance between performance and graphical quality. YMMV.

Fedora 8 now has the same problem.

kmod-nvidia-173.14.12-1.lvn8
xorg-x11-drv-nvidia-libs-173.14.12-1.lvn8
xorg-x11-drv-nvidia-173.14.12-1.lvn8
kmod-nvidia-2.6.25.11-60.fc8-173.14.12-1.lvn8

Looks like it's very much the driver.
