blue screen in splash and login screen

[m_o_b]

after booting to mandriva2007 with KDE the screen turns blue just before the login screen and i can't see a thing. even when i login (i'm not using password) and the desktop still blue nothing i can see.

that's happened when i changed the 3d from metisse to beyrl while compiz used to work perfect.

is there i can do from safe mode.

You could try booting from CD and get access to your HD. From there you might be able to fix this problem.

I always feel it's safer not to boot directly into graphics mode because of these type of problems. But you can get access to your install through booting a CD.

if i boot from a cd where i can find those files?

sorry i'm new to linux and it doesn't use letter like windows

If you boot from a Linux LiveCD you can mount the partition (that is if the LiveCD doesn't automatically mount it) then you can access your /etc/X11/xorg.conf and revert the changes that are causing these problems.

Good luck

thank you for your respond

but i really don't know what to do with this file. what causing me this problem is beryl and i need to make the desktop no 3d for know how would i do it when i open the /etc/X11/xorg.conf file.

thank you

When you boot from a lifeCD open up a terminal. Note! You do not want to change /etc/X11/xorg.conf. Because that one is the xorg.conf on the lifeCD. You want the file from your HD, so you have to mount your HD. Try to do something like this:

Su
Password:
mkdir /mnt/HD
mount /dev/hda1 /mnt/HD
cp /mnt/HD/etc/X11/xorg.conf /mnt/HD/etc/X11/xorg.conf.backup (<= a life saver)

Or, I dunno, use sudo instead of su. That you have to preceed all above commands with sudo.

Start your favorite editor and open /mnt/HD/etc/X11/xorg.conf (as root)

Try to find out where the problem is. Commend out the guilty party (by adding # to the front of the line), make sure you commend on the changes you make, so you can easily find and undo your changes.

I always type either:
# user added <nr of lines>
# user enabled <nr of lines>
# user disabled <nr of lines>
This makes it really easy to grep a file for home brew changes.


Oh, and if you can find /mnt/HD/etc/inittab, you may want to change the default runlevel to 3. This saves you the constant rebooting. You can change it back once you've got it working again. (This is very optional however, just something I prefer myself)

If you're in doubt, you can post the contents of /mnt/HD/etc/X11/xorg.conf here, and let's have a looksy.

Once you're done with the xorg.conf reboot without the lifeCD.

i can't modify none of the file...........how can i login as superuser in lifecd

[Freston]

Oh, right. su or sudo don't work?

I believe *digs deep into memory* that the root password was 'mandriva'. Or, eh, 'root'. Not really sure. Perhaps it's just enter.

[netstrider]

Don't log in as super user, just use sudo in front of all your commands

[m_o_b]

on the command i loged in as su but when try to modify the text with kwrite i cant save it.

i highlight what i think is the problem

i think it's the 3d thing.

i just wnat to disable it for now.

thanx again.
