Hi, I've updated my computer from F14 to F15 final with the DVD (preupgrade doesn't work as my /boot and / partitions are on md devices). F15, AMD64, 6GB RAM, nvidia GeForce 6150. I use propietary nvidia drivers from rpmfusion. gdm login screen shows perfectly but once the session is started a) if nautilus handles desktop => there is a black background, no image shown, no icons, no right-click menu with the mouse b) if nautilus doesn't handle desktop (default in GNOME 3) => background image is shown, but... in both cases every window/app I open appears as black rectangles, even no windows decorations. Some times, the first app I open is shown correctly, but no more. I know apps are running, but windows are not drawn on screen and appears as black windows. Topbar "applets" (calendar, user menu, nm-applet, etc) and their menus work ok, and when I press WINDOWS key it shows the Activities screen with no problems, I can see the background, left dock, workspaces at right, search for apps... NO problems, and it's fast. But when I come back to normal screen, windows are black rectangles (except maybe the first one). I don't think if problem comes from nvidia drivers but as in F14 I was using gnome-shell at it worked ok, I think issued comes from mutter/gnome-shell => compositor? Btw, using nouveau driver goes to fallback mode. My graphics card is a nvidia GeForce 6150, maybe old, but worked ok and even fast with gnome-shell from F14. I've tried uninstalling rpmfusion drivers and installing old and new/beta drivers from nvidia website, but same problem. I've search and find other people share same problem with ATI cards [1], that's the reason I think problem is composition or maybe xorg.

I've been testing many things last couple of days, no luck. I've also been looking carefully at many logs: /var/log/{Xorg.0.log, messages audit/audit.log}, .xsessions-errors, dmesg and glxinfo output... Everything seems correct, no errors. If you need them I can attach the logs. Here, another bug I think related to this one: https://bugzilla.redhat.com/show_bug.cgi?id=707650
Excuse me for the monologue, but I think I've found something... it looks there are some problems with xorg 1.10 and nvidia drivers 270.x when using KDE and transparency, maybe it's related with the issue I have.

I have the same problem, but with the nouveau drivers. Installed Fedora 15 (Default DVD media), and once I login to Gnome 3, I get a black screen with 'patches' everywhere. My display card is an integrated nvidia GeForce 6150. I doubt if it is due to the desktop effects ? Is there any way to turn the effects from command line?
I also have an integrated GeForce 6150, my motherboard is a ASUS M2NPV-VM. But in my case, it doesn't run GNOME 3, always goes to fallback mode, showing the next error: [ 41.268] (EE) NOUVEAU(0): Error creating GPU channel: -16 [ 41.269] (EE) NOUVEAU(0): Error initialising acceleration. Falling back to NoAccel Did you do something special? Anyway, I've read many reports with compositing/transparency errors with xorg 1.10 and nvidia drivers 270.x, so I think there are some bugs there at least.
Iñigo: After a couple of reboots I realized that the problem occurs only once in a while. Whenever I'm logging into GNOME, if I hover my mouse around, there is a good chance that I hit the problem. On other cases (If I leave the mouse as is), the login happens just fine, and GNOME 3 is running too. I've never tried nvidia binaries, but I think there could be problems to be addressed in Xorg/GNOME 3 ? I cannot access terminal/logs whenever the problem happens, so cannot attach any logs to look for any clues..
I have same problem. With nouveau, I experienced screen corruption sometimes, and decided to try nvidia drivers. With them, I also see a background and a top bar, but nothing else is drawn. I installed KDE and it works in this configuration, so, I guess, the problem is on Gnome's side.
I've solved my original problem, so I will close the case. I'm not completely sure about what happened but it looks like a bug of nvidia propietary drivers with last version 1.10 of xorg-server. In my case, after lots of hours testing I finally got gnome-shell work without those "black windows". My graphics card is a GeForce 6150 embedded on an Asus M2NPV-VM mother board. I took a look at BIOS and saw a setting called "Frame buffer size for onboard graphic", whose value was 32MB, I changed it to the maximum, 256MB, and gnome-shell works now. Note that with Fedora 14's gnome-shell (xorg 1.9, nvidia 260.x) it worked. Anyway, nVidia has reproduced the issue (and other regarding screen corruption) on their labs and they are working in a fix.
