Linux Not starting


Hi Gurus,

I have installed Mandrake 10.2 and it was working until yesterday. I tried to configure internet sharing through the control center and the system hanged. I did a forced reboot. After that, my linux system doesn't come up. I can see in verbose mode that everything starts OK, but I am not getting the KDE screen to logon. I tried to fix it using rescue and nothing seems to help. How could I fix this? Any help is really appreciated.

Thanks,
meetmefar

When you say you see the verbose messages, I'm assuming these are the boot messages flashing by? In which case, when they are finished, what happens - does the monitor simply turn black? I would have expected it to bring you a text-based login, where it simply prompts for your username. Here, enter "root" and the password your provided during the install.

Hi, meetmefar -

fouldsy's absolutely correct. It sounds like your system is booting to text mode; if so, my suggestion would let you manually get the rest of the way into graphics mode.

Before you leave text mode, however, it probably wouldn't hurt to write down (verbatim!) any error messages you might see among the boot messages. Once (if!) you log in, all these messages can also be seen in the system log file "/var/log/messages".

Of particular interest is the LAST (bottom most) message before the login prompt.

You might have to hit "Enter" before seeing a login prompt. but it's probably there...

'Hope that helps .. PSM

Hi,

The monitor doesn't turn black. I can see a very faint display of empty screen without any text based login.

Thanks,
meetmefar

can't you boot and stay in text-mode? e.g. using the your boot manager (lilo, grub, etc).

meetmefar,

I've had this problem before, and for me it's been linked to the boot loader. I haven't used Mandrake before, so I'm not sure what bootloader it uses. I'll assume lilo, seeing I know the option off the top of my head.

As root you need to edit your /etc/lilo.conf file and look for the vga option. Change this so it reads vga = normal, save the file and run lilo from the command line. How you can edit this file seeing you can't log in? Try using a live CD distro like Knoppix, or if you can boot using the Mandrake CD somehow (I'm not sure)?

Restart the box and see how that goes.

I'm at work at the moment so let me know how it goes and I'll be able to help you more when I get home.

Good luck,
Kristijan

Hi Kristijan,

Thanks for your help. In a frustration, I have installed Linux in another partition. Now I have two installations of Linux, but only one starts, the new one(shows in the lilo menu). How could I access the other partition so that I could move the files from one partition to another? When I type df in the command line, I am seeing two mount points (of the new disk )
/dev/hdb1 5.8G 1.8G 3.7G 33% /
/dev/hdb6 30G 36M 30G 1% /home

OK I did this. Removed the new installation. I am back to square1. With the old installation with blank screen. I tried your suggestion. changing thelilo.conf file, but it didn't help.

Thanks,
meetmefar

I've never heard of anything like this, but Kristijan's suggestion that it could have to do with the boot loader is entirely plausible.

Remember - the bootloader starts out in BIOS text mode, then switches over to BIOS *graphics* mode. From there on, all the "text" is actually bitmapped graphics. My guess is that whatever "messages" you see are all in BIOS text mode only, and that maybe the bootloader's "fbdev" display driver can't handle your system's video card.

Question:
Did you try Kristijan's suggestion about editing /etc/lilo.conf?

(Related) question:
Can you successfully boot from *ANY* Linux on this PC (for example, boot from CD)?
