Fglrx AMD Driver troubleshooting on ubuntu-gnome 15.04


I install fgrlx driver on vivid os the driver look like is istalled correct on system and built the necessary kernel modules because the dpkg log not report any errors, i configured the driver by simple commands like:

sudo aticonfig --initial

sudo aticonfig --screen-layout=on

i reboot the machine , but i face an strange issue the boot splash screen is hangup,i cant enter my lvm password to boot the system, i was have a chance to boot into rescue mode when boot to rescue mode the display not read by the system i try to export display by

export DISPLAY=:0

I try to configure /etc/X11/xorg.conf there is not good resaults the boot splash still hang up

I edited the grub , i uncomment "quiet splash" modified by "nomodeset"

i can boot without boot splash but im faced other issue i cant switch to virtual tty

i dont know is this a bug in the driver or in the kernel

any suggest

You need modesetting for a tty/X swap to work.

I would comment out "quiet splash" and "nomodeset", as the more information available, the quicker problems get solved. To help people help you, Post the output of
Code:
lspci |grep VGA
and details of your system

As a quick fix, edit /etc/inittab. There is a section something like this:
Code:
 # These are the default runlevels in Slackware:
#   0 = halt
#   1 = single user mode
#   2 = unused (but configured the same as runlevel 3)
#   3 = multiuser mode (default Slackware runlevel)
#   4 = X11 with KDM/GDM/XDM (session managers)
#   5 = unused (but configured the same as runlevel 3)
#   6 = reboot

# Default runlevel. (Do not set to 0 or 6)
id:3:initdefault:
Change the digit in the last line (3 in my case) to be the 'Multiuser' mode. You log in on one of the ttys, and type 'startx' to get into X.

Using console runlevel was the advice, whatever way Ubuntu implement it. X is started using something else - xdm? never bothered with it. Here I just seem to have Xorg running, and a window manager

No the problem is you canít boot. The second problem is that is zero benefit to FGLRX with your old school graphics card. Any computer you might want to do will be handed just as well with the OS drivers that do work and youíre not playing games games on that classic GPU.

Actually there is a reason to use fglrx....

I have an HP Elitebook 8460p with Ubuntu 15.04. It has the radeon 6400m/7400m graphics card.

The reason I installed fglrx was to have control of the overscan and underscan properties which are not available with the default radeon driver - as far as I could tell. When I connect the laptop to a Seiki TV with HDMI and 1080p, the visible area is slightly larger than the monitor.

With the AMD control center I can control the overscan and get the screen size to match the monitor.

And yes, I also have the problem where the virtual terminals are black.

I verified they are *functional* by logging into one and doing a 'wall' command so the issue appears to be that the foreground and background color of the framebuffer are both black.
