hi friends. Seems like fedora is giving me enough troubles now and then. I recently install AT radeon drivers in f15 and after that even though it worked properly and had no issues with rebooting. But from the third time onwards, when booted, it is loaded ie., I see a screen with fedoraa's icon and later it gives a black screen. I dont get the login option or anything. Just blank. I dont know what the problem is. It might not even be related to those drivers at all. Please help me on how to proceed on this issue.


Now I am able to login.However, I get an error window saying "Unfortunately GNOME 3 failed to start properly and started in the fallback mode.

This most likely means your system (graphics hardware or driver) is not capable of delivering the full GNOME 3 experience."
Does that mean Cant i use drivers for using graphic cards?

Please show us your /var/log/Xorg.0.log file.

this is the log file. Thanks in advance

You may have the proprietary drivers from AMD installed but your xorg.conf file (if you have one) doesn't tell Xorg to use the fglrx driver. You need to create a new xorg.conf file with 'aticonfig --initial'. Then reboot, and try again.

Adam

It looks like your glx module is coming from ATI (AMD) but the Radeon module is from Xorg. Does this find anything?
If not you haven't loaded your proprietary driver.

Till he fixes his xorg.conf file to load just "fglrx", there's not much point in checking that output.

Adam

After creating that xorg.conf file, I got the blank screen again. It seems that keyboard takes the input but monitor doesnt display anything.

How can I uninstall those drivers and install default graphic card drivers of F15?
I dont even know what those drivers are.

lsmod |grep fglrx -This doesn't give any output either.

thanks a lot for bearing.

If you want to get back to the open source drivers, we can help with that. If you want to try and get fglrx working, we can help with that as well.

So, to get back to the open source drivers, you will need to uninstall the proprietary ones you currently have installed. How you do that, though, depends entirely on how you installed the drivers in the first place... So how'd you do that?

I followed this process. WHen I screwed up, I removed those abovesaid drivers through add/remove software. Now, can i delete the xorg.conf file so that I can log back into fedora or will that create any problems?

It seems better if I undo waht I did and then reinstall ATI radeon 3400 drivers so that everything works properly again. How to do that?

Thanks.

Just a point of information from Adam about this problem. Does xorg in Fedora still use an xorg.conf file? I'm using Xorg 7.6 and there's no xorg.conf file - only an xorg.conf.d folder.

Never mind. I just read your previous post and see that you create it using aticonfig --initial but I don't understand how a proprietary GLX got loaded but not fglrx. I'm confused about this.
ciao & thanks,

Kamal Reddy, yes, once you remove those packages via add/remove software, remove your /etc/X11/xorg.conf file and reboot. If all goes well, you will be back to using the open source drivers that come with F15 by default.

jdkaye, Xorg still uses an xorg.conf file if it is present.

Adam

Please tell me correct drivers that should be installed for AT radeon 3400 on F15.
Does Fedora 15 support this video card ?

There are no "correct" drivers. You have two to chose from: the open source driver that F15 comes with or the proprietary driver that you installed via that guide you mentioned above. Both drivers support 2D and 3D acceleration. The open source drivers are better for using gnome3. You do not, typically, need to do anything to install the drivers since they come with Fedora 15.

Adam

one final doubt please...

Now blank screen is gone and I am able to use fedora but now the look is different from previous. I dont know how to put it but now for example,I get 'Applications' and 'Places' on top left instead of hot corner. I think all those effects are disabled which have anything to do with video card.

Thanks
Kamal

I don't know how Gnome works but I imagine it has a System Settings app which can configure things like Desktop Effects. That's where you should be able to enable or disable desktop effects. I know that on my KDE (4.6.5) the default was for the effect to be disabled. If Gnome is similar then you may need to enable them.
