install of Natty leads to panic on login or nothing

[Traejan]

Hi everyone, big fan of linux:
ok I was running Karmic Koala on my Hp and was loving it after running previous states of Ubuntu...I recently upgraded toNatty and was all excited when it installed with out a hitch, but when I went to log in, it froze after the third icon or would send the screen into a scrolling lines of text before stoppin and saying Kernel in Panic, not Syncing....I tried looking on here for a solution but didn't really see one that fit the situation. I went into recovery and did sudo aptget -y -f update and upgrade twice. and I even created a second boot disk and thunb stick bootable. I can run Kubuntu as a trial from the thumbstick, which I thought about just going with that and try the install again (4th time) but its not a full os so can use virtual box or chrome from there. I do not have a invidia or ati graphix card,

I have a HP compac dc5700. original MB, 1Tb HDD..yes I know its old in computer standards, but its never failed me and was always willing to run an version of Ubuntu/Kubuntu

Sorry... but no new help here on this issue yet...

However, I have had this same issue on a new install of 32 bit Kubuntu on an older Intel P4 motherboard running Natty 11.04.

After the install that all went well, I rebooted and got to the splash screen with the logon box. I entered my credentials and the system started to load up. It then did a kernel panic during the third icon while trying to start the kde desktop. At this point, the system was totally hung (keyboard lights flashing.)

This issue seems to be related to the Kubuntu Natty install and the specific hardware your installing on as I have installed both the 32 bit and the 64 bit Kubuntu Natty 11.04 on different hardware with no issues. (In fact, I loaded a 32 bit Ubuntu 11.04 dist on the same box having the issues and it worked just fine.)

My guess is that its a video related issue....

If I get a minute, I'll try to pull the error messages created on boot from the system log and post them here.

Cheers
Bill

Hi traejan

could you tell us your video card?

Ok... well I finally had some time to test my hypothesis regarding the video card as being the likely suspect causing the kernel panic... Bingo!

I booted to the 11.04 signon screen. Then did a ctl-alt-F1 to get a terminal window in Kubuntu (without logging on to KDE.) At this point, I went to the default directory (/etc/default) and modified grub2 file to boot as follows:

sudo nano /etc/default/grub

Change the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.modeset=0"

Then rebuild the grub.cfg file by running:

sudo grub-mkconfig --output=/boot/grub/grub.cfg

Once this is all done do a

sudo shutdown -r now

to reboot. At this point I was able to boot into the KDE graphical desktop signon screen and actually signon and get to the graphic desktop without kernel faulting.

This means that the issue is defiantly a video driver issue with Kubuntu and the Intel video cards. I still need to do some more research to see where to go next... but I suspect I'll have to retrograde the driver. Just a cursory look points back to KMS.. more research ahead... ack.. phft!

cheers
