Screen blanking out after x number of minutes.

**theAdmiral** · 03-19-2010

I have been having an issue with my screen blanking out after a few minutes (number of minutes unknown), since I reinstalled Fedora 12 (KDE) a couple of weeks ago. I have tried, yes, a lot of things to try to set it so that it doesn't blank out, to no avail. I have spent a lot of time on the Fedora forum seeking resolution, with a variety of suggestions, all to no avail. Has anybody had this problem, or is anybody familiar with this problem, and can offer some help? I went into System Settings > Power Control, and fooled with things around there and they didn't work. I tried xset and dpms and shutting them off. Still no cigar. Seems like I'm running out of things to try, but am wondering if somebody has experienced this and could tell me how to handle it, please?

Thank you kindly,
theAdmiral

Are you using correct, supported Graphics Driver? Is xorg.conf configured?

Post the output of this

Code:

su -
/sbin/lspci | grep -i vga

Post the contents of /etc/X11/xorg.conf file here.

**theAdmiral** · 03-19-2010

[root@localhost theAdmiral]# /sbin/lspci | grep -i vga
01:00.0 VGA compatible controller: nVidia Corporation GeForce 8400M GS (rev a1)
[root@localhost theAdmiral]#

[root@localhost theAdmiral]# cat /etc/X11/xorg.conf
cat: /etc/X11/xorg.conf: No such file or directory
[root@localhost theAdmiral]#

Uh, yeah, I think I need more help, please.

xorg.conf is not configured and you haven't installed Nvidia Driver.

Have you installed rpmfusion repository?

Code:

yum repolist

Post output here.

Thanks for the diagnosis for this noob. What's next, please?

[root@localhost theAdmiral]# yum repolist
Loaded plugins: presto, refresh-packagekit

Execute these commands :

Code:

su -
rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
rpm -ivh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm

First will install RPMFusion repository and second will install its GPG Key.

Install Nvidia Driver :

Code:

yum install kmod-nvidia

You have to edit /boot/grub/grub.conf file to blacklist native nvidia driver.

Execute this

Code:

su -
nano /boot/grub/grub.conf

It will open grub.conf file in nano editor.

Add rdblacklist=nouveau at the end of kernel line.
Sample ::

Code:

kernel /boot/vmlinuz-2.6.21-1.3228.fc7 ro root=LABEL=/ vga=773 rdblacklist=nouveau

Press Ctrl+X, Y and hit Enter key to save file.

Reboot machine.

This is what I have:

Code:

        initrd /initramfs-2.6.31.5-127.fc12.i686.img

What do I change, please?

**devils casper** · 03-19-2010

Add at the end of kernel line under title Fedora (2.6.32.9-70.fc12.i686)

Code:

title Fedora (2.6.32.9-70.fc12.i686)
        root (hd0,0)
        kernel /vmlinuz-2.6.32.9-70.fc12.i686 ro root=/dev/mapper/luks$ rdblacklist=nouveau

Save file and reboot machine.

I followed your directions, Sir. Still yet to tell whether KPackageKit likes it. Still yet to tell whether the intended change took place. But, I have another problem as a result. My pc is encrypted, and when I boot up, there used to be a password dialog that came up to pass into the encryption, like an encryption login before the user login. Now that I have made this latest change, there is no dialog, just a black screen with a file path, I think, and at the end is a colon and blinking cursor. I can enter my password, and it shows up as asterisks, instead of the usual fat dots. But, it gets me in. If possible, I would like to get the blue background dialog back, the way it was before. Any ideas on this would be great! And you are doing a fine job so far! A heck of a lot better than the yay-hoos that tried to help me (or were possibly having fun with me) on the Fedora Forum.

Thanks again very kindly,
theAdmiral

There is a bug somewhere. KPackageKit isn't liking it. It comes up with 2 or 3 dozen updates. So, I try to install them, and after 4 the computer wants to restart because of KPackageKit. I restarted and rebooted, and got the same error.
