I get this problem in BT5-Gnome-32
I managed to get my install working using the notes in this forum thread.

I added "i915.modeset=1" to my kernel command line for my intel chipset.
More information for other video chipsets may be here if its the same problem as I had. http://ubuntu4beginners.blogspot.com...n-problem.html
Hmm... At first I thought that this might have been related to the fact that I have an nvidia card with optimus---Nvidia GT 335M with switchable Intel GMA 4500MHD---as this technology is unsupported by X server but many of the machines listed above do not have switchable graphics.
This issue (X server causing a kernel panic) has occurred all over the linux landscape in the past:

My guess is that the installation somehow creates a misconfigured /etc/xorg.conf file (see https://wiki.ubuntu.com/X/Config ) because when I run BT5 live X has no problem at all starting up. When I get home from work I am going to try to create a new vanilla file with: sudo Xorg -configure . If that doesn't work, or if someone doesn't solve this for GNOME in the next few hours, I am going to try bumblee: https://github.com/MrMEEE/bumblebee which might provide a workaround to this bug for those of us who are stuck with optimus.

I have the same thing happening with a Dell 5510, core i5 with the Intel Corporation Core Processor Integrated Graphics Controller rev. 02.
Once you launch X, it appears the kernel panics as the scroll and caps lights start flashing and it hard locks. So I don't think its regulated to just a ATI issue, tho it is obviously a driver issue :/
Anyone else having this issue?
Edit:
I tried the Xorg -configure and created a new .conf file, no dice here with the Intel GMA. It looks like is a problem all over the landscape but it *seems* to have been fixed in the newer kernels within ubuntu (if i'm following the majority of these threads) and those are older than the current kernel being used by BT5. argh - more digging i suppose!
For those with intel HD integrated video laptops, this is your fix. Just tried it out now and it worked. THanks snipes420 for the help!

I tried that and it didn't work for me. I had just put the command at the end of the kernal commands, does it HAVE to be placed before a certain command? If so, where?Quote:

^ The line on my grub was:
text splash nomodeset vga=791
so i changed nomodeset to i915.modeset=1 and then changed it permanently in the /etc/default/grub
You can also change the line to quiet splash i915.modeset=1
Thank you so much! I'm typing this on my laptop right now. I must have been blind as a bat to not see the "text splash nomodeset vga=791." As soon as I changed it, it worked perfectly.Quote:
